This series tries to add a DMA memory test to the mtest tests. The DMA test performs bursts to SDRAM which can be useful in stressing memory and can be difficult to produce reliably in certain circumstances (eg running with data caches disabled).
It can be enabled on 85xx and 86xx boards by defining CONFIG_FSL_DMA, CONFIG_SYS_ALT_MEMTEST, and CONFIG_SYS_DMA_MEMTEST.
Other platforms will need to support the dmacpy() function in order to enable the DMA memory test.
