[U-Boot] [PATCH] Tricorder: Fix boot after making software ecc configurable

[Thomas Weber]

The tricorder stops booting with the following message:

U-Boot 2011.12-00325-ga661206 (Feb 13 2012 - 09:29:50)

OMAP3503-GP ES3.1, CPU-OPP2, L3-165MHz, Max CPU Clock 600 mHz
OMAP3 Tricorder + LPDDR/NAND
I2C:   ready
DRAM:  128 MiB
NAND:  CONFIG_MTD_ECC_SOFT not enabled
0 MiB
MMC:   OMAP SD/MMC: 0

Adding CONFIG_MTD_ECC_SOFT to config file fixes this problem.

Sorry about that -- I meant to exclude "nand: make 1-bit software ECC
configurable" from the patchset I applied, due to the potential for this
sort of breakage.

We should revert that patch until the issues raised here are resolved:

I had / have plan to take the tricorder patch tomorrow, unless you
really want to push a revert from your tree instead.  Either way is
fine with me.

This affects more than just tricorder -- any board that depends on soft
ECC will be broken, since none of them define this symbol.  I thought I
had left this patch out, but apparently didn't.
