[U-Boot] [PATCH 1/9] mmc: mmc header fix

[U-Boot] [PATCH 1/9] mmc: mmc header fix

[Mateusz Zalega]

Structure definition used type block_dev_desc_t, defined in part.h, which
wasn't included in mmc.h. It worked only in circumstances when common.h,
or another header using part.h was incuded in implementation files.

[U-Boot] [PATCH 2/9] part: header fix

[Mateusz Zalega]

Implementation made use of types defined in common.h, even though it
wasn't #included. It worked in circumstances when .c files included
every needed header (all).

[U-Boot] [PATCH v3 3/9] arm:goni: Update configuration for goni target

[Mateusz Zalega]

Configuration file for GONI has been updated to support FAT file system,
new mmc partitioning scheme and read linux kernel from eMMC instead of
OneNAND.

It's an updated version of an earlier patch which didn't make it to mainline
due to dependencies.

[U-Boot] [PATCH 4/9] arm:goni:dfu Add support for DFU to Goni target

[Mateusz Zalega]

Proper adjustment for supporting DFU at GONI target has been made.
The s5p_goni.h file has been updated. Moreover, the code for low level
USB initialization has been added to Goni board code.

The malloc pool has been enlarged in order to support larger buffer
sizes needed by DFU implementation.

[U-Boot] [PATCH v3 7/9] dfu:mmc: raw data write fix

[Mateusz Zalega]

When user attempted to perform a raw write using DFU (vide
dfu_fill_entity_mmc) with MMC interface not initialized before,
get_mmc_blk_size() reported invalid (zero) block size - it wasn't
possible to write ie. a new u-boot image.

This commit fixes that by initializing device in get_mmc_blk_size() when
needed.

Tested on Samsung Goni.

v2 changes:
- code cleanup
- minor dfu_alt_info format change

v3 changes:
- moved invalid block length check to mmc core
- removed redundant 'has_init' check

[U-Boot] [PATCH 8/9] ums: always initialize mmc before ums_disk_init()

[Mateusz Zalega]

In some cases MMC was still uninitialized while media capacity check,
leading to broken ums command.

[U-Boot] [PATCH 9/9] USB: gadget: added a saner gadget downloader registration API

[Mateusz Zalega]

g_dnl core were replaced by a linker list made of {usb_function_name,
bind_callback) pairs.

[U-Boot] [PATCH v3 7/9] dfu:mmc: raw data write fix

[Jaehoon Chung]

Hi, Mateusz,

This patch should be separated with dfu and mmc.

Why this condition needs?

Could you test those g_dnl related patches?

You would probably need to apply the whole series for testing.

Thanks in advance.

It doesn't have to go through get_timer(). The effect, although
negligible, saves some cycles.

NAK, it improves code readability.

I added it as a countermeasure after fixing the bug and mistook its
purpose when writing a late update to this patch, my bad.

Given the circumstances it might be a sound assertion, but we shouldn't
clobber the codebase that we aim to optimize for size, should we.

ACK, will remove.

If you're asking to put this if() block after variable declaration, NAK.

It's perfectly fine C99 code. I'm not aware of any existing U-Boot style
guidelines that would forbid me to leave it this way.

These variables are only meaningful when mmc_init() returns a valid pointer.

[U-Boot] [PATCH v2 01/12] mmc: mmc header fix

[Mateusz Zalega]

Structure definition used type block_dev_desc_t, defined in part.h, which
wasn't included in mmc.h. It worked only in circumstances when common.h,
or another header using part.h was incuded in implementation files.

[U-Boot] [PATCH v2 07/12] arm:goni:dfu Add support for DFU to Goni target

[Mateusz Zalega]

Proper adjustment for supporting DFU by Goni target has been made.
The s5p_goni.h file has been updated. Moreover, the code for low level
USB initialization has been added to Goni board code.

The malloc pool has been enlarged in order to support larger buffer
sizes needed by DFU implementation.

[U-Boot] [PATCH v2 10/12] dfu:mmc: raw data write fix

[Mateusz Zalega]

When user attempted to perform a raw write using DFU (vide
dfu_fill_entity_mmc) with MMC interface not initialized before,
get_mmc_blk_size() reported invalid (zero) block size - it wasn't
possible to write ie. a new u-boot image.

This commit fixes that by initializing device in get_mmc_blk_size() when
needed.

Tested on Samsung Goni.

Can you follow this advice and build a macro for declaring these USB devices ?

btw would you mind fixing the example for ll_entry_declare() in linker-lists.h ? 
It has four params in the example for some reason (it's a remnant from rework).

Are these two new functions called from multiple places at all? If not, just 
inline these ll_foo() calls and be done with it. FYI you can also make macros 
for these to avoid having to type all these args all around and duplicating the 
code.

callback++ , this is not C++ where the order might matter. Nonetheless, you do 
want to use ll_entry_count() and ll_entry_get() with an iterator variable 
instead to make sure you don't step onto a corrupted field and crash in some 
weird way.

Macros or static inlines, it's all the same, there's no point in
changing that. The symbols aren't visible outside this compilation unit
and function calls are, well, inlined.

don't bug me.

I don't think using ll_entry_get() in this way is possible with current
implementation of linker lists. Moreover, there's plenty of code doing
just the same already accepted to U-Boot.

Linker would have to split sections to make this sort of thing possible.

NAK, what you say is seriously wrong, you should know that by now!

Macros do not do any kind of typechecking, functions do typechecking.
Macros are expanded in place during preprocessing, functions are (usually) 
single-instance.

etc.

It's pointless to have them pulled out so explicitly. Or would you prefer to 
have each function encapsulated in another function ? This doesn't make does 
now, does it ?

What I would like to do is for you to follow the advice in linker_lists.h and 
produce a small shim over these crude linker lists prototypes there, so that the 
users here in the g_* world don't have to type the whole linker list macros with 
all the arguments, which do not ever change for this g_* . Does it make sense 
please?

Can be done on purely statistical grounds, try this:

$ git grep 'for.*(.* *++[:alnum:]\+ *)' | wc -l
13
$ git grep 'for.*(.* *[:alnum:]\+++ *)' | wc -l
183

Please fix, thank you.

Ah meh, sorry. Seems like someone was messing with the linkerlists and 
misdesigned it. Dang.

Yeah, and it's all the same if you don't care for typechecking and all
that, which I assumed from _you_ proposing usage of macros here.

It's taken care of by static inlines.

You're guaranteed by the linker, and our setup, that all your

You will need macros wherever you do some kind of strange expansion. If you 
don't need to do strange expansion, use inline functions wherever possible. But 
I think in case of the linker generated lists, you really cannot avoid using 
macros.

Sure ...

Actually, looking at this, you are right that wrapping the LL macro with a 
function is a good idea.

Yes OK, you do have a point.

This doesn't mean someone won't corrupt it, but that's for an entirely different 
discussion I'd say.

This new CONFIG_USB_CABLE_CHECK macro doesn't work. Why don't you introduce a 
__weak version of usb_cable_connected() instead and drop this macro altogether ?

This patch certainly does more than that I think, no ?

Moreover, it's up to the user to init the MMC before using it, don't you agree?

Sorry, this really doesn't explain what was the bug, what caused the bug and why

[U-Boot] [PATCH v3 01/13] mmc: mmc header fix

[Mateusz Zalega]

Structure definition used type block_dev_desc_t, defined in part.h, which
wasn't included in mmc.h. It worked only in circumstances when common.h,
or another header using part.h was incuded in implementation files.

[U-Boot] [PATCH v3 07/13] arm:goni:dfu Add support for DFU to Goni target

[Mateusz Zalega]

Proper adjustment for supporting DFU at GONI target has been made.
The s5p_goni.h file has been updated. Moreover the code for low level
USB initialization has been added to GONI board code.

The malloc pool has been enlarged in order to support larger buffer
sizes needed by DFU implementation.

[U-Boot] [PATCH v3 10/13] dfu:mmc: raw data write fix

[Mateusz Zalega]

When user attempted to perform a raw write using DFU (vide
dfu_fill_entity_mmc) with MMC interface not initialized before,
get_mmc_blk_size() reported invalid (zero) block size - it wasn't
possible to write ie. a new u-boot image.

This commit fixes that by initializing device in get_mmc_blk_size() when
needed.

Tested on Samsung Goni.

Hm, actually, I see we have open issues with the 04/13 V2 patch (why don't you 
have default __weak usb_cable_detection() implementation instead of another 
#ifdef ?).

The whole patchset is a mix of completely unrelated things which should go 
through different trees. Can the patchset be reordered/split in some reasonable 
chunks ? There are fixes which should go in immediatelly and then features which 
should go in for -next.

btw. please keep custodians on CC of the respective patches.

Existing code relied on boolean value returned from
usb_cable_connected(), but there was no way to signal that it's
impossible to tell whether cable is connected or not. If you prefer an
enum with USBCNT_DONTKNOW as a return value, make a decision.

Not exactly unrelated, most of it should be applied in this particular
order. It would be less chaotic had it been accepted in one piece.

Did I say anything about "USBCNT_DONTKNOW" above please?

Sorry, I also lost context of this thread as it was dead for more than a month.

Please elaborate why can the fixes not go first and features second. Thank you.

As I described on the IRC. We've got to have a way to signal U-Boot code
that our hardware isn't capable of knowing if cable is connected, thus
#ifdef all related code or introduce 3-valued enum.

It's because of silly relationships between some of these patches. ie.
am335x SPL build process just blew (too little ROM), leaving its
codebase in unbisectable state, after I added some more code to DFU
implementation. am335x's SPL had to be disabled first, and I consider it
a change on the feature list.

I've reordered the fixes I could, but I guess it doesn't matter anymore,
now that -next is out.

Please ack applicable USB patches on the next patchset version or
propose a different solution.

[U-Boot] [PATCH v4 00/13] DFU, MMC, Gadget, Goni, misc.

[Mateusz Zalega]

This is, I hope, the final version of patchset.

Custodians: please ack appropriate patches.

Minkyu Kang: Could you pick it up after it gets reviewed by the community?

patches 1-7: fixes that can be applied before features
patches 8-13: features and fixes that depend on features

Patchset has been tested by running MAKEALL -a arm on every commit, so that it
wouldn't break bisect.

[U-Boot] [PATCH v4 01/13] mmc: mmc header fix

[Mateusz Zalega]

Structure definition used type block_dev_desc_t, defined in part.h, which
wasn't included in mmc.h. It worked only in circumstances when common.h,
or another header using part.h was incuded in implementation files.

[Mateusz Zalega]

mmc_init() doesn't call get_timer() anymore if MMC is already
initialized.

[U-Boot] [PATCH v4 06/13] dfu: mmc: raw data write fix

[Mateusz Zalega]

When user attempted to perform a raw write using DFU (vide
dfu_fill_entity_mmc) with MMC interface not initialized before,
get_mmc_blk_size() reported invalid (zero) block size - it wasn't
possible to write ie. a new u-boot image.

This commit fixes that by initializing device in get_mmc_blk_size() when
needed.

Tested on Samsung Goni.

[U-Boot] [PATCH v4 07/13] ums: always initialize mmc before ums_disk_init()

[Mateusz Zalega]

In some cases MMC was still uninitialized while media capacity check,
leading to broken ums command.

[U-Boot] [PATCH v4 11/13] arm: goni: dfu: Add support for DFU to Goni target

[Mateusz Zalega]

Proper adjustment for supporting DFU at GONI target has been made.
The s5p_goni.h file has been updated. Moreover the code for low level
USB initialization has been added to GONI board code.

The malloc pool has been enlarged in order to support larger buffer
sizes needed by DFU implementation.

OK, so I guess a weak default implementation returning -ENOTSUP would work.

I suggest we go for the weak default implementation of usb_cable_connected() 
which would return -ENOTSUP in the default case. Override with board-specific 
stuff if needed.

[U-Boot] [PATCH v5 00/12] DFU, MMC, Gadget, Goni, misc.

[Mateusz Zalega]

Patchset contains fixes for:
* DFU write issues
* USB cable detection
* ums command
* U-Boot's base framework (headers)
* fixed base DFU offsets
and features:
* convenient USB Gadget registration
* Samsung Goni DFU, UMS, GPT bringup
also:
* am335x will no longer support DFU in SPL builds

There _are_ dependencies between these patches. ie. Goni stuff depends on the
new Gadget registration API, which in turn depends on disabling DFU in
am335x's SPL build so that some poor soul wouldn't trip over a board-breaking
commit while running git bisect, and I could have not written correct code
without fixing u-boot headers first...

Changes since v1:
- reordered "USB: gadget: added a saner gadget downloader registration API"
- fixed a bug related to usb_cable_connected() which broke previous Goni
  configuration patches
- disabled DFU in TI's am335x SPL build due to insufficient ROM capacity
since v2:
in "USB: gadget: added a saner gadget downloader":
fixed issues which came to [Marek Vasut]'s attention:
- fixed coding style issues
- added convenient macro wrappers for used ll_entry_declare
since v3:
- grouped patches related to common topics
in "ums: always initialize mmc before ums_disk_init()"
- Added const attribute of ums_disk_init introduced type warnings. It would
  take a lot of changes to MMC core code to fix it, so it was dropped, even
  though ums_disk_init shouldn't and doesn't change struct mmc it is passed.
since v4:
- added detailed changelog to each patch
- removed patches which can go in separately:
  "common: fixed linker-list example"
  "mmc: postponed needless timer initialization"
in "dfu: mmc: raw data write fix":
- commit message was made more detailed
- the patch was split in two, introducing
  "dfu: mmc: change offset base handling" to the patchset
in "usb: dfu: fix boards wo USB cable detection":
- removed CONFIG_USB_CABLE_CHECK
- moved implementation from usb.h (reserved for USB host code)
  to USB gadget
- renamed usb_cable_connected to g_dnl_usb_cable_connected
- removed defunct board implementations (origen, universal)
- added __weak default implementation and removed ifdef'd blocks around
  dependent code
in "gadget: added a saner gadget downloader"
- fixed coding style issues reported by [Jaehoon Chung]

[U-Boot] [PATCH v5 01/12] mmc: mmc header fix

[Mateusz Zalega]

Structure definition used type block_dev_desc_t, defined in part.h, which
wasn't included in mmc.h. It worked only in circumstances when common.h,
or another header using part.h was incuded in implementation files.

[U-Boot] [PATCH v5 03/12] usb: dfu: fix boards wo USB cable detection

[Mateusz Zalega]

Former usb_cable_connected() patch broke compilation of boards which do
not support this feature.

I've renamed usb_cable_connected() to g_dnl_usb_cable_connected() and added
its default implementation to gadget downloader driver code. There's
only one driver of this kind and it's unlikely there'll be another, so
there's no point in keeping it in /common.

Previously this function was declared in usb.h. I've moved it, since
it's more appropriate to keep it in g_dnl.h - usb.h seems to be intended
for USB host implementation.

Existing code, confronted with default -EOPNOTSUPP return value,
continues as if the cable was connected.

CONFIG_USB_CABLE_CHECK was removed.

[U-Boot] [PATCH v5 04/12] dfu: mmc: raw data write fix

[Mateusz Zalega]

When user attempted to perform a raw write using DFU (vide
dfu_fill_entity_mmc) with MMC interface not initialized before,
get_mmc_blk_size() reported invalid (zero) block size - it wasn't
possible to write ie. a new u-boot image.

This commit fixes that by initializing MMC device before use in
dfu_fill_entity_mmc().

While fixing initialization sequence, I had to change about half of
dfu_fill_entity_mmc's body, so I refactored it on the way to make it,
IMHO, considerably more comprehensible.

Being left as dead code, get_mmc_blk_size() was removed.

Tested on Samsung Goni.

[U-Boot] [PATCH v5 05/12] dfu: mmc: change offset base handling

[Mateusz Zalega]

Previously offsets handled by dfu_fill_entity_mmc(), defined in boards'
CONFIG_DFU_ALT were treated as hexadecimal regardless of their prefix,
which sometimes led to confusion. This patch forces usage of explicit
numerical base prefixes.

[U-Boot] [PATCH v5 06/12] ums: always initialize mmc before ums_disk_init()

[Mateusz Zalega]

In cases when MMC hadn't been initialized before, ie. by the user or other
subsystem, it was still uninitialized while UMS media capacity check,
leading to broken ums command.

UMS has to initialize resources it uses.

Tested on Samsung Goni.

Changes since v3:
- Added const attribute of ums_disk_init introduced type warnings. It would
  take a lot of changes to MMC core code to fix it, so it was dropped, even
  though ums_disk_init shouldn't and doesn't change struct mmc it is passed.
Changes since v4:
- added slightly more detailed commit message

[U-Boot] [PATCH v5 10/12] arm: goni: dfu: Add support for DFU to Goni target

[Mateusz Zalega]

Proper adjustment for supporting DFU at GONI target has been made.
The s5p_goni.h file has been updated. Moreover the code for low level
USB initialization has been added to GONI board code.

The malloc pool has been enlarged in order to support larger buffer
sizes needed by DFU implementation.

I've agreed with Marek Vasut about those patches. I will take them to
u-boot-dfu tree and send PR to Marek.

Since this is a cleanup patch (not connected to DFU/USB) I would like
to take it to the u-boot-dfu to prevent it from being vanished on the
ML.

Tom, could you ACK this patch? And then I will add it to u-boot-dfu.

I've agreed with Marek Vasut about patches 1 to 8. I will take them to
u-boot-dfu tree and send PR to Marek.

However, I would like to ask you to add patches from 9 to 12 (related to
GONI) to u-boot-samsung tree.

Below, please find links to patchwork:

It's probably better to just switch from find_mmc_device() to
get_device(), which does the initialization internally. patch "ums: use
get_device() not find_mmc_device()" does this.

http://patchwork.ozlabs.org/patch/344328/

That said, at this point, it's probably simplest to just apply this
series, and I'll rebase my series on top of this in a day or two.

[U-Boot] [PATCH v5 05/12] dfu: mmc: change offset base handling

[Lukasz Majewski]
