2007-08-13atmel_mci: Fix data timeout valueHaavard Skinnemoen
Calculate the data timeout based on values from the CSD instead of just using a hardcoded DTOR value. This is a backport of a similar fix in BSP 2.0, with one additional fix: the DTOCYC value is rounded up instead of down. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-08-13atmel_mci: Use 512 byte blocksize if possibleHaavard Skinnemoen
Instead of always using the largest blocksize the card supports, check if it can support smaller block sizes and use 512 bytes if possible. Most cards do support this, and other parts of u-boot seem to have trouble with block sizes different from 512 bytes. Also enable underrun/overrun protection.

2007-04-14Atmel MCI driverHaavard Skinnemoen
Driver for the Atmel MCI controller (MMC interface) for AT32AP CPUs. The AT91 ARM-based CPUs use basically the same hardware, so it should be possible to share this driver, but no effort has been made so far. Hardware documentation can be found in the AT32AP7000 data sheet, which can be downloaded from http://www.atmel.com/dyn/products/datasheets.asp?family_id=682 Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
