Hi,
this patchset adds basic support for the ZynqMP family of ARM64
SoC+FPGA by Xilinx and for the ZCU106 board based on it.
The ZynqMP sets a few challenges that needed some work besides the
usual defconfig + readme that is enough for more classic and simple
SoCs.
This v5 addresses the comments received to v4 by Joel (BR2_EXTERNAL
not working). It also fixes support for providing a PMU firmware as a
local file, while keeping the ability to download it.
I reordered the patches w.r.t. v4. Here's their summary.
The first issue is the PMU (Platform Management Unit). It is a
Microblaze core that handles power and clock gating and the like, and
reprogramming it during early boot is necessary to boot any modern
U-Boot and Linux. Since we can't build Microblaze code out of the
ARM64 toolchain, U-Boot obtains a pre-built binary either from a local
file or downloaded using EXTRA_DOWNLOADS. This is added in patch
1. Until v3, the PMUFW had to be copied inside the U-Boot source. With
a patch from upstream it is now possible to avoid the copy.
With this in place, patch 2 just adds the defconfig and board files.
Patch 3 allows to pass an externally-supplied init file to U-Boot,
which is needed to boot boards not supported in the U-Boot source
code, or on the same boards but with a different
configuration. Instead of copying the user-provided file inside the
U-Boot source as in v3, I applied a patch from upstream so U-Boot is
able to build that file without any copy. ZCU106 is supported by
mainline U-Boot with a default configuration and thus it does not need
this patch, so I have moved it at the end.
