[RESEND PATCH 1/2] ARM: OMAP2+: nand: Make board_onenand_init() visible to board code

[Javier Martinez Canillas]

board_onenand_init() and board_nand_init() initialization functions are
used to initialize OneNAND and NAND memories respectively. But only
board_nand_init() was visible to be used from board code. This patch makes
possible to initialize a OneNAND flash memory within platform code.

[RESEND PATCH 2/2] OMAP3: igep0020: Add support for Micron NAND Flash storage memory

[Javier Martinez Canillas]

IGEP-based boards can have two different flash memories, a OneNAND or
a NAND device. The boot configuration pins (sys_boot) are used to
specify which memory is available.

Also, this patch removes unnecesary code for registering the OneNAND.

Tony,

Can you please merge this patch and:

[RESEND PATCH 1/2] ARM: OMAP2+: nand: Make board_onenand_init()
visible to board code

I've sent this two patches several times and no one is against them. I
also had positive feedback such as Enric's acked-by

These two patches are a fix and needed to boot newer versions of the
IGEPv2 board. Without the patches the board doesn't even boot.

Please tell me if you need me to resend the patches.

Best regards,

Hi Tony, Russel:

This patch is a requirement for patch:

[RESEND PATCH 2/2] OMAP3: igep0020: Add support for Micron NAND Flash
storage memory

which is really important since newer IGEPv2 boards have changed their
flash memory from OneNAND to NAND.

This patch-set is necessary to make the board work, otherwise it
doesn't even boot.

Could we please include these patches?

Thanks a lot and best regards,
Javier

This patch breaks the build for platforms that don't use ONENAND.
Using omap2plus_defconfig, set CONFIG_MTD_ONENAND_OMAP2=n and you'll get
the build error below[1]

By removing the static, there is now duplicate definitions in the .c and
.h files.

The solution is to remove the dummy definition from the .c file.  

Tony, feel free to fold the diff below[2] into the original patch to fix
this compile problem.

Kevin

That's already merged as 8259573b (ARM: OMAP2+: nand: Make board_onenand_init()
visible to board code) so we need to apply it as a fix.

Can you do a fix with your Signed-off-by or at least reply with that
so I can apply it?

Thanks,

Tony

Here you go.  Applies to your 'board' branch.

Subject: [PATCH] ARM: OMAP2+: nand: fix build error when
 CONFIG_MTD_ONENAND_OMAP2=n
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

commit 8259573b (ARM: OMAP2+: nand: Make board_onenand_init() visible
to board code) broke the build for configs with OneNAND disabled.  By
removing the static in the header file, it created a duplicate definition
in the .c and the .h files, resuling in a build error:

/work/kernel/omap/dev/arch/arm/mach-omap2/board-flash.c:102:111: error: redefinition of 'board_onenand_init'
/work/kernel/omap/dev/arch/arm/mach-omap2/board-flash.h:56:51: note: previous definition of 'board_onenand_init' was here

make[2]: *** Waiting for unfinished jobs....
make[1]: *** [arch/arm/mach-omap2] Error 2
make: *** [sub-make] Error 2

Fix this by removing the duplicate dummy entry from the C file.
