uboot environment from within OpenWRT

[lambda]

Hi,

writing it down here so I know where to look it up
once I forget again: To have fw_printenv/fw_setenv
work you need a file /etc/fw_env.config with the
follwing line:

/dev/mmcblk0   0x40000   0x4000

(I have no reason to believe this is correct other
than that it works for me. I didn't read the source
or whatever.)

HTHSE,
Harald
