[U-Boot] [RFC 00/10] New board-specific USB initialization interface

[U-Boot] [RFC 00/10] New board-specific USB initialization interface

[Mateusz Zalega]

Current implementation of do_dfu() and do_usb_mass_storage() requires
board-specific board_usb_init() which performs USB hardware initialization.

I noticed that several boards have such a function defined, named either
usb_board_init() (which binds to ohci-hcd.c driver and had been used solely
by it) or board_usb_init() (as in ehci-omap.c). I _assumed_ that these functions
do what's required by do_*() and renamed the earlier in order to unify the naming
convention.

It would:
+ make enabling DFU and UMS in these boards easier
+ clean up the namespace
+ improve code reusability
+ enable devs to postpone hardware init until it's needed (as in do_dfu())

Declarations of these functions were scattered all over the codebase. Seeing it
as a bad practice, I added declaration of usb_board_init() in usb.h and removed
the other.

I added a weak symbol for usb_board_init() in usb.c so that boards which do not
require USB initialization or have to initialize hardware earlier would compile
and run.

For boards which offer both USB device and host capabilities, you can specify
which part, host or device, to initialize, via function argument.

Does this approach sound good and/or reasonable?

Code compiles successfully for all ARM boards and was tested on Samsung Goni.

I appreciate your efforts, but this whole area clearly falls into the
domain of the device model rework.  Is your suggested implementation
in any way synchronized with what has been discussed about this topic
before?

Best regards,

Hello,

I've caught up with driver model discussion. The changes I submitted are
related to sharing of board-specific hardware initialization functions
between drivers, therefore my patches, if I don't miss anything, do not
collide with driver model rework - these changes would have to be done
anyway.

Regards,

With just this patch applied, nothing calls that function. This breaks
"git bisect".

This needs to be part of the previous patch (or part of that patch needs
to be split out and put into this patch) so that this prototype change
happens in the same patch that the implementation is renamed. Perhaps
this can happen before the current patch 1?

Moving the pinmux initialization might be dangerous; pin_mux_usb() might
prevent the pins used for USB having a mux function selected that
conflicts with some other pins selected mux function. We really do need
to initialize all of the pinmux early, and not defer it.

If new USB driver model would use some other API to deal with
board-specific functions, please correct me. I didn't manage to find
related information, maybe I didn't look for it carefully enough.

[U-Boot] [PATCH] usb: new board-specific USB init interface

[Mateusz Zalega]

This commit unifies board-specific USB initialization implementations
under one symbol (usb_board_init), declaration of which is available in
usb.h.

---
Changes since RFC:
- NVIDIA Tegra doesn't postpone its USB init anymore
- board_usb_init()'s sole argument name was shortened
- networking code comment style (/* blurb...) dropped
- squashed RFC changes so that patch won't break bisect

The EHCI supports multi-bus thing (passing the controller *), will this be 
viable to pass in this case too, so the busses can be inited selectively in 
host/gadget functions?

[U-Boot] [PATCH v2] usb: new board-specific USB init interface

[Mateusz Zalega]

This commit unifies board-specific USB initialization implementations
under one symbol (usb_board_init), declaration of which is available in
usb.h.

Changes since RFC (v1):
- NVIDIA Tegra doesn't postpone its USB init anymore
- board_usb_init()'s sole argument name was shortened
- networking code comment style (/* blurb...) dropped
- squashed RFC changes so that patch won't break bisect

v2 changes:
- commit message fixup

Hello, Marek.
I need more context. Could you show me the part of code in which you'd
like to pass/use additional arguments?

Please grep the 'controller' pointer that is passed to various functions at 
least in the EHCI case. It would be nice to pass that to the init functions too, 
no?

It may be possible, but note that board_usb_init() is not used solely by
EHCI code (please grep or cscope function calls). In order to do that,
we would need to devise some generic interface.

Is it worth the time? Are there targets that would benefit from this change?

In case you want to separatelly init one port for USB peripheral mode and one 
for Host mode, yes.

We could add another argument: "int controller_index" (or maybe "const
char* controller_id"), which would correspond to node names or aliases
defined in devicetree source files (ie. see: tegra30.dtsi). List of
available controllers would be accesible via ie. "usb list" command.
Implementations of board_usb_init() would lookup applicable hardware in
gd_t.

We would need to find a way to differentiate between these controllers
in cases when it would be expected from u-boot to automatically
initialize devices it needs. It looks easy in case of ehci-tegra.c.

Devicetree-agnostic boards would have their own "usb list"
implementation, and those of them that can't initialize their
controllers selectively would be left the way they are with just one
additional, unused board_usb_init() argument.

Device tree is completely ortogonal to this. See how "int usb_lowlevel_init(int 
index, void **controller)" is declared. Pass something similar, index at least. 
Also pass the mode in which the controller should operate.

DT is not present on all platforms, so you _MUST_ handle the non-DT case too.

[U-Boot] [PATCH v3] usb: new board-specific USB init interface

[Mateusz Zalega]

This commit unifies board-specific USB initialization implementations
under one symbol (usb_board_init), declaration of which is available in
usb.h.

Changes since RFC (v1):
- NVIDIA Tegra doesn't postpone its USB init anymore
- board_usb_init()'s sole argument name was shortened
- networking code comment style (/* blurb...) dropped
- squashed RFC changes so that patch won't break bisect

v2 changes:
- commit message fixup

v3 changes:
- added 'index' argument to perform selective port initialization

OK, a few general ideas again:

Why not wrap board_usb_init() and board_usb_init_fail() into single call. You 
now pass some flags to board_usb_init() already, so just add another for the 
fail case. How does it sound to you?

Moreover, the 'int index' should likely be unsigned int and the special value to 
init all controllers at once should probably then be 0xffffffff

Best regards,
Marek Vasut

Like overengineering. It would lead to "board_usb_init(USB_INIT_ALL,
USB_INIT_DEVICE, USB_CLEANUP)" calls, which are not very readable.

Despite our greatest ambitions, I don't think we're likely to use more
than 2^31-1 USB controllers at a time. Besides, negative values look
better both in code and debugger session.

This is not what I mean, see this:

int board_usb_init(int index, enum board_usb_init_type init)

Add a new "init" type (or maybe change the init field to be flags) that will say 
"OK, do a fail init" ?

Thinking of it further, instead of using negative value here, like I mentioned 
above, why not make the "board_usb_init_type" into a field of flags , then add 
flag to init all controllers at once ?

As for providing a way to do a selective cleanup if anything gone wrong,
it's a good idea, but adding such functionality to board_usb_init()
would be confusing, especially for newcomers. Why not do this in
board_usb_init_fail(int index, enum board_usb_init_type)?

...and maybe rename board_usb_init_fail to board_usb_cleanup.

That's unnecessary. It wouldn't lead to any practical advantage over
existing interface.

Cleanup is nice name, yeah.

The advantage would be you won't be mixing two things (value AND value with 
special meaning) into the "index" parameter.

Alright, provide a use-case. The only 'special' value we have now
doesn't interfere with controller index. Why write code or interfaces
that won't ever be used?

Look, abusing the index field with a special value is moronic, especially if you 
_do_ have another field that can very well be turned into a block of flags 
instead of enum right next to it.

function(int foo , enum bar)
            |         ^
            |         |
            `---------'
             flags go
               here

Then int foo can be turned into unsigned int foo _and_ be used for it's one 
singular purpose. Likewise, enum bar will now be "unsigned int flags" . Do you 
see the separation now ?

I wouldn't call a de-facto standard abusive or moronic.
On the other hand, contributing to unnecessary code bloat would be.

Have you provided another use-case for that, as I asked?

Read your mail carefully - at this point I don't have any problems
understanding what you wish to do, but I see your API changes as
unjustified. Can you justify them without appealing to your authority
and maybe inserting a couple of ad-hominems here and there?

[U-Boot] [PATCH v4] usb: new board-specific USB init interface

[Mateusz Zalega]

This commit unifies board-specific USB initialization implementations
under one symbol (usb_board_init), declaration of which is available in
usb.h.

New API allows selective initialization of USB controllers whenever needed.

- board_usb_init()'s sole argument name was shortened
- networking code comment style (/* blurb...) dropped
- squashed RFC changes so that patch won't break bisect

v2 changes:
- commit message fixup

v3 changes:
- added 'index' argument to perform selective port initialization

v4 changes:
- board_usb_init_fail() renamed to board_usb_cleanup()
- board_usb_cleanup() accepts controller index and init type
- DFU and UMS commands don't init all USB controllers anymore
- minor related fixes & refactorization

Afterall, we do not want to init _ALL_ ports at once, but we want to init them 
selectively.

Looks pretty much OK. Did you test it on a few platforms? I'd like to apply this 
for -next anyway, since the MW is long closed.

I've ran MAKEALL on all arm boards and tested it on Samsung Goni.
Everything seems to be OK.

How did you test it on all the ARM boards ?

ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- BUILD_DIR=/tmp/u-boot-arm-build 
MAKEALL_LOGDIR=/tmp/u-boot-arm-log ./MAKEALL -a arm

does this work for you ?

I checked powerpc and "arches" "glacier" and "glacier_nand" don't build. Can you 
please check and fix ? You can get the ELDK 5.4 PPC toolchain from [1].

They don't touch any usb core stuff, they're just samsung-specific configuration 
adjustments. They should go via u-boot-samsung.

Hello,
it's because I moved some function declarations and had to include usb.h
in their code.

@usb.h, this giant ifdef fails:
134 #if defined(CONFIG_USB_UHCI) || defined(CONFIG_USB_OHCI) || \
135         defined(CONFIG_USB_EHCI) || defined(CONFIG_USB_OHCI_NEW) || \
136         defined(CONFIG_USB_SL811HS) ||
defined(CONFIG_USB_ISP116X_HCD) || \
137         defined(CONFIG_USB_R8A66597_HCD) ||
defined(CONFIG_USB_DAVINCI) || \
138         defined(CONFIG_USB_OMAP3) || defined(CONFIG_USB_DA8XX) || \
139         defined(CONFIG_USB_BLACKFIN) || defined(CONFIG_USB_AM35X) || \
140         defined(CONFIG_USB_MUSB_DSPS) ||
defined(CONFIG_USB_MUSB_AM35X) || \
141         defined(CONFIG_USB_MUSB_OMAP2PLUS)

and results in:
169 #error USB Lowlevel not defined

I don't like the notion of using board-specific CONFIG_* defines in
usb.h. Any ideas on where can we move it? Maybe one generic
CONFIG_USB_HOST specified in board code would do?

Can you please elabore which functions did you exactly move that cause this to 
fail now ?

The ifdef is pretty much what would CONFIG_USB_HOST do.

Yeah, but it would be nice to be able to add more boards to u-boot
without touching usb.h.

CONFIG_USB_OMAP3 <-- what happens in arch/board code should stay there

[U-Boot] [PATCH v5] usb: new board-specific USB init interface

[Mateusz Zalega]

This commit unifies board-specific USB initialization implementations
under one symbol (usb_board_init), declaration of which is available in
usb.h.

New API allows selective initialization of USB controllers whenever needed.

Changes since RFC (v1):
- NVIDIA Tegra doesn't postpone its USB init anymore
- board_usb_init()'s sole argument name was shortened
- networking code comment style (/* blurb...) dropped
- squashed RFC changes so that patch won't break bisect

v2 changes:
- commit message fixup

v3 changes:
- added 'index' argument to perform selective port initialization

v4 changes:
- board_usb_init_fail() renamed to board_usb_cleanup()
- board_usb_cleanup() accepts controller index and init type
- DFU and UMS commands don't init all USB controllers anymore
- minor related fixes & refactorization

v5 changes:
- fixed an issue with boards based on canyonlands.c
- patch passes MAKEALL -a powerpc (vide: ^)

[U-Boot] [PATCH v5] usb: new board-specific USB init interface

[Marek Vasut]

Dear Mateusz Zalega,

> This commit unifies board-specific USB initialization implementations
> under one symbol (usb_board_init), declaration of which is available in
> usb.h.
> 
> New API allows selective initialization of USB controllers whenever needed.
> 
> Signed-off-by: Mateusz Zalega <m.zalega@samsung.com>
> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
> Reviewed-by: Lukasz Majewski <l.majewski@samsung.com>
> Cc: Marek Vasut <marex@denx.de>
> Cc: Lukasz Majewski <l.majewski@samsung.com>
> ---
> Changes since RFC (v1):
> - NVIDIA Tegra doesn't postpone its USB init anymore
> - board_usb_init()'s sole argument name was shortened
> - networking code comment style (/* blurb...) dropped
> - squashed RFC changes so that patch won't break bisect
> 
> v2 changes:
> - commit message fixup
> 
> v3 changes:
> - added 'index' argument to perform selective port initialization

Hey, can you please rebase on top of usb/next ? I'd like to run build tests and 
apply.

Best regards,

[U-Boot] [PATCH v6] usb: new board-specific USB init interface

[Mateusz Zalega]

This commit unifies board-specific USB initialization implementations
under one symbol (usb_board_init), declaration of which is available in
usb.h.

New API allows selective initialization of USB controllers whenever needed.

Changes since RFC (v1):
- NVIDIA Tegra doesn't postpone its USB init anymore
- board_usb_init()'s sole argument name was shortened
- networking code comment style (/* blurb...) dropped
- squashed RFC changes so that patch won't break bisect

v2 changes:
- commit message fixup

v3 changes:
- added 'index' argument to perform selective port initialization

v4 changes:
- board_usb_init_fail() renamed to board_usb_cleanup()
- board_usb_cleanup() accepts controller index and init type
- DFU and UMS commands don't init all USB controllers anymore
- minor related fixes & refactorization

v5 changes:
- fixed an issue with boards based on canyonlands.c
- patch passes MAKEALL -a powerpc (vide: ^)

v6 changes:
- rebased onto usb/next

I'm a little late to the game, but can you rename this to just 
usb_init_type ?
I'm wanting to use this as a parameter to usb_lowlevel_init, moving it
above the usb_lowlevel_init definition would help me too.


Thanks
Troy

Looks like Marek already applied it. You can always send another RFC.
