More fun n900 booting debian900 via BBBSD

BBBSDdebian900Boot.m4v

i had to cheat cause uboot follows the spec more than the cards values and assumes 25MHZ while i report 400khz.
kernel comes from mmc.

time to login after first BBBSD access 6:37 min
login takes around 30 sec.

i couldnt find enough fast pins so i went for 1 bit sdio at 400 khz giving a random io of around 14kb/s

single block read, multi block write working
(they saved single block writes as fallback as well as crc7 check on cmd (so did I))
