[edk2-devel] [PATCH 0/2] EMMC2 fix _DMA for newer SOC

[Jeremy Linton]

The _DMA range needs to change depending on the SOC in use, this
was part of the problem with enabling DMA by default because there
wasn't a clear way to determine the SOC revision in use.

Now that we have an id register for that, we can pick the correct
_DMA at runtime. Lets also flip DMA on by default.
