Subject: [PATCH 0/2] EMMC2 fix _DMA for newer SOC
Date: Tue, 11 May 2021 17:41:47 -0500 [thread overview]
Message-ID: <20210511224149.864718-1-jeremy.linton@arm.com> (raw)
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.
