shannon/INFERNO: fix special handling of environment configuration
Remove some INFERNO related #ifdef's from common environment code by fixing the board configuration settings (add CONFIG_ENV_SECT_SIZE). While we are at it, fix comment which incorrectly talks about 4 KB environment size, while it's actually 0x4000 = 16 KiB. Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: Rolf Offermanns <rof@sysgo.de>
