this seems to work much nicer for me. only odd thing is that 'fatls' does not
work if i dont 'mmcinfo' first. do you see the same ? maybe this is
(currently) expected behavior ?
from cold boot:
bfin> mmc_spi 4
MMC_SPI: 0 at 0:4 hz 25000000 mode 0
bfin> fatls mmc 0:1
MMC: block number 0x1 exceeds max(0x0)
** Can't read from device 0 **
** Unable to use mmc 0:1 for fatls **
bfin> mmcinfo
