[U-Boot] IXP42x patch series - 2nd attempt

[U-Boot] IXP42x patch series - 2nd attempt

[Michael Schwingen]

Hi,

here is my IXP42x patch series, which brings my IXP boards back to life
after relocation was added.  I hope I addressed all comments I got from the
pervious patch.


Notes:

I added the XScale sub-architecture to the MAINTAINERS list to get a better
overview which boards may still need work:
[PATCH 01/13] add XScale sub architecture (IXP/PXA) to board list

The NPE library needs a fix for B1 silicon - the special handling is only
needed for Rev.  A0, but the code treats everything *but* B0 as being the
old A0 silicon:
[PATCH 02/13] add support for IXP42x Rev. B1 and newer

The dvlhost board has a watchdog that needs to be triggered regularly:
[PATCH 03/13] trigger hardware watchdog in IXP42x serial driver

Rework the startup and timer code:
[PATCH 04/13] Fix IXP code to work after relocation was added

make fails during depend pass in the NPE directory, due to missing include
files:
[PATCH 05/13] fix "depend" target in npe directory

Board updates:
[PATCH 06/13] add wildcard to sections (for -ffunction-sections/-fdata-sections)
[PATCH 07/13] update/fix AcTux1 board
[PATCH 08/13] update/fix AcTux2 board
[PATCH 09/13] update/fix AcTux3 board
[PATCH 10/13] update/fix AcTux4 board

The following changes should be OK (not sure about the environment location
on IXDP425 - the old value is inside the monitor area, which seems to be
wrong for this type of flash/linker script).  I do not know if these should
be committed, or should be left for the board maintainers:
[PATCH 11/13] update/fix some more IXP42x boards (only compile tested)

Add support for MII links that run at fixed speed, without a PHY with
standard registers (ethernet switch on AcTux-2/AcTux-3, powerline modem on
dvlhost):
[PATCH 12/13] IXP NPE: add support for fixed-speed MII ports

Add one new board:
[PATCH 13/13] add dvlhost (dLAN 200 AV Wireless G) board

That's not a "board list", but the MAINTAINERS file (I would
expect changes to boards.cfg when I read "board list").

> -	wepep250	xscale
> +	wepep250	xscale/pxa (removed)

What does "removed" mean? When it's removed, then please remove.

Best regards,

Wolfgang Denk

Right. Do you waht a patch with an updated comment?

It looks like it is already removed - I could not find support for that
board in the current code, but I think removing maintainers is nothing
*I* should do without further discussion?

Well, this got removed by Marek in commit 7369478.


Marek, it seems you forgot to clean up MAINTAINERS, and also to add
the removed boards to the "doc/README.scrapyard" file.  Can you please
provide cleanup patches for these commits:

4262a7c   2010-10-22 01:38:01 +0200   PXA: Remove "xsengine" board
7369478   2010-10-22 01:38:01 +0200   PXA: Remove "wepep250" board
75e2035   2010-10-22 01:38:01 +0200   PXA: Remove "delta" board

Thanks.

Best regards,

Wolfgang Denk

Hi, I believe I sent the patch finally ... I hope this can be closed then.

This code is broken. You must not access any variables in BSS segment
(like these two) before relocation.

It should then be possible to remove the CFLAGS line, right?

That does not seem to work - I need both. I do not have a full
understanding of the Makefile structures, but I guess the inclusion  of
CPPFLAGS into CFLAGS happens before I can add to CPPFLAGS.

Please always use I/O accessors.  Please fix globally.

You should use get_ram_size() here.

Can we please get rid of this file completely?

If you have a better proposal where to add -ffunction-sections and
--gc-sections?

In my previous patch, I proposed a generic config switch (which added
those flags in the generic Makefile) for that, but the only comment I
got was from Mike Frysinger, stating that an extra config switch was
unnecessary when I could simply set those variables in the board config.mk.

Those two switches make for a significant reduction in code size (~61000
bytes, nearly one flash sector!), so dropping them is no real option.

Which solution would you prefer?

These should go to arch/arm/config.mk or at least arch/arm/cpu/*/config.mk

It makes little sense to enable this on a per board level.

I got out everything except the LDSCRIPT definition. However, I can't
find a way to specify a board-specific linker script (which I need due
to the embedded environment) without using config.mk in the board
directory, since the platform sets up a non-board default in
arch/arm/config.mk.

How about a
#define CONFIG_BOARD_LDSCRIPT
that is picked up by autoconf.mk and used in the Makefiles if set?

PowerPC uses CONFIG_SYS_LDSCRIPT for this.

Thanks, found it - I had only searched non-architecture Makefiles.
I can copy that mechanism to ARM.

Since I am not the maintainer of these boards, I tried to keep the
changes minimal.
I can go ahread if noone protests, but I can only test IXDP425 (we have
one at work), and I can't guarantee compatibility with old u-boot versions.

A student of  probability  soon  realizes  that  by  its  nature  the
billion-to-one  chance  crops  up nine times out of ten, and that the
greatest odds boil down to a double-sided statement: it will  happen,
or it will not.         - Terry Pratchett, _The Dark Side of the Sun_

Please drop that file, it should not be needed.

Incorrect multiline comment style, please fix globally.

You should use get_ram_size() here.

Do you really need a board specific linker script?
It looks pretty much generic to me.

Please always use I/O accessors.  Please fix globally.

Please do not undef what is not defined anyway. Please fix globally.

By the way, ALL software projects are done by iterative  prototyping.
Some companies call their prototypes "releases", that's all.

Same as the other AcTux boards: where should I move these
compiler/linker flags?
