At91SAM9G20 AT91_MCI patches

[Retallack, Mark]

Good morning, I hope this is the correct list. 

I am using the AT91SAM9G20-EK dev board. It does not look like the vanilla kernel (2.6.27+) contains the patch for support in the drivers/mmc/host/at91_mci.c file. Patch 5130/3 contains the correct information, however the final patch 5130/4 has the at91_mci section removed. Was there a reason for this?

Also it would be useful to know what the preferred MCI (MMC) driver for the AT91SAM9G20 is; the at91_mci or atmel_mci. The revision A and B AT91SAM9G20-EK dev board (board-sam9g20ek.c) uses the at91_mci driver, but the revision C AT91SAM9G20-EK dev board (board-sam9g20ek-2slot-mmc.c) uses atmel_mci driver.

Thanks in advance
