[U-Boot] "CONFIG_MTD_ECC_SOFT not enabled" breakage/change

While finishing some work on support for a new machine, a build based on the latest git, I see this: ........................... U-Boot 2011.12-00374-g54e9668-dirty (Mar 02 2012 - 14:48:48) Pogoplug E02

SoC: Kirkwood 88F6281_A0 DRAM: 256 MiB WARNING: Caches not enabled NAND: CONFIG_MTD_ECC_SOFT not enabled 0 MiB `````````````````````````````

which is very reminiscent of what Thomas Weber mentions here: http://lists.denx.de/pipermail/u-boot/2012-February/117926.html

Is it now considered standard and expected practice to enable CONFIG_MTD_ECC_SOFT in the machine config ?

Or is this a fluke/bug/commit error that is awaiting a fix?

thanks,
