[U-Boot-Users] [PATCH 1/3] SDHC Support for AT572d940HF-EB

[COSTA, Antonio]

Hi Ulf, good to hear from you again.
I'm trying apply patches to U-Boot but they beat my hands a bit,
they are very severe :). Now I'm fixing // comments, line lentgh, ...

SDHC patch is not complete because PATCH 2/3 bounced due to size problem (40.5 KB)
so the patch is invalid.

Anyway, in my patch I introduced a function that computes the frequency runtime
and I use it to configure the DTOR register so some care should be taken here.

As I written in the patch I put atmel_mci.c and atmel_mci.h in relevant board directories
insted in drivers because this is a proposal.

In fact I want to get the rid of MASTER_CLOCK declaration to have U-Boot able to run at different frequencies.
The one in my atmel_mci.c is just the first step.

Regards,
Antonio

I do not think that Antonio has any AT91SAM9260 boards.
Pls check what is happening with a JTAG emulator and propose a patch.

Best Regards
