+
+ atmel_mci: Fix data timeout value
+
+ 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.

+
+ AVR32: Include <div64.h> instead of <asm/div64.h>
+
+ include/asm-avr32/div64.h was recently moved to include/div64.h, but
+ cpu/at32ap/interrupts.c wasn't properly updated (an earlier version of
+ the patch was merged perhaps?)
+
+ This patch updates cpu/at32ap/interrupts.c so that the avr32 port
+ compiles again.

+
+ atmel_mci: Use 512 byte blocksize if possible
+
+ 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.

+
+ macb: Introduce a few barriers when dealing with DMA descriptors
+
+ There were a few theoretical possibilities that the compiler might
+ optimize away DMA descriptor reads and/or writes and thus cause
+ synchronization problems with the hardware. Insert barriers where
+ we depend on reads/writes actually hitting memory.
