[U-Boot] AT91 working SD with u-boot

[Konrad Mattheis]

Hi Sebastian,

yes I'm using an AT91SAM9G20-EK Rev.c with two SD slots.
I used slot a but I think you just have to init slot b.

in PatchV3 you can read:

>at91_mci0_hw_init(int slot, int bus_width)

>switch (slot) {
>		case 0:
>			.....
>		case 1:
So I think you just have to call at91_mci0_hw_init(1,4) for
slot b.

bye
Konrad
