[U-Boot] [PATCH 0/2] Fix onenand command after ARM relocation changes.

[U-Boot] [PATCH 0/2] Fix onenand command after ARM relocation changes.

[Enric Balletbo i Serra]

Hello,

After ARM relocation support the onenand command seems broken, these patches attempt to solve this issue.

The first patch fixes the usage help for onenand command when no arguments are passed. 

The second patch relocate the onenand command table manually, I think this is required after relocation changes but I'm not sure if this is the best solution, so comments are welcome.

Tested on IGEP v2 and OMAP3 IGEP module boards.

Cheers,
  Enric

Running the onenand command without arguments does nothing, with this
patch shows the command usage.

We also have to relocate the onenand command table manually, otherwise
onenand command don't work.

Could you try

git://git.denx.de/u-boot-arm.git elf_reloc

branch? With this branch, it is not longer necessary to do
such fixups.

bye,
Heiko

Of course :-)

> With this branch, it is not longer necessary to do such fixups.

Here my tests:

   U-Boot # onenand erase
   OneNAND erase: whole chip
   OK

Yes, seems the patch 2/2 it's not longer necessary, the onenand
command works without this patch.

U-Boot # onenand
(hang)

I think the patch 1/2 it's also necessary, otherwise the onenand
command without arguments hangs.

Cheers,
  Enric

Is this patch still necessary? I thought the relocation change made it OBE.

As I reply to Heiko this patch [2/2] it's not necessary if elf_reloc
branch is merged. OTOH I think the patch [1/2] of the same series it's
necessary.

 [PATCH 1/2] cmd_onenand.c: Fix command usage help.
