this device has a tSD on mmc2 instead of an ugly nand, which is awesome.
BUT I can't see it when booting from our u-boot on mmc0.

is this something to fix in boards.cfg, or we just don't support mmc2? I
ask because (obviusly) I would like to boot from the tSD[1] ;-)
never mind, just found CONFIG_MMC_SUNXI_SLOT. will send a v2 soon.
yet another self reply...
based on board/sunxi/board.c's mmc_pinmux_setup() MMC_SUNXI_SLOT=3
should match the setup for accessing the tSD according to the .fex
<http://sprunge.us/WbMM?ini#n-647> but:
"Card did not respond to voltage select!"
any idea what I'm missing?
cheers,
Alejandro Mery
