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
Device: MMC_SPI
