Dear Rob Emanuele,
this patch applies to current TOT, however it does not work flawlessly:
TOP9000> fatls mmc 0:1 gen_atmel_mci: CMDR 0x00001050 (16) ARGR 0x00000000 (SR: 0x00000000) COMMAND Dbg Msg gen_atmel_mci: CMDR 0x00051051 (17) ARGR 0x00000000 (SR: 0x00000000) COMMAND Dbg Msg
*** system hangs here ***
But, if preceeded by a mmc read command it works (except for some odd clock related messages):
TOP9000> mmc read 0 21000000 0 1

Which hardware(CPU) did you test it, and which u-boot version?
