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

[David Purdy]

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,
