Hi All,
Here is a massive update for the ARM aarch64 port. With the following
series the aarch64 port should be on par with the 32bit support.
With this aarch64 supports relocatable binaries, proper MMU support, DMA
cache maintenance operations, and finally starting a aarch64 Linux
image :)
This all has been developed on a i.MX8MQ EVK board. The i.MX8MQ patches
are currently evolving, but are not yet quite ready. DDR setup is still
very crude and pinmux is not yet working. NXP did a nice job with the
i.MX8MQ: It behaves very much like a i.MX6 with a different core, so
we already have most of the drivers and I could concentrate on the
aarch64 update. I hope I can send i.MX8 patches soon.
