This patch adds a new boot firmware to buildroot for building the zynqmp pmufw.
It requires the toolchain-bare-metal package that includes a bare-metal
binutils, gcc and newlib which can be built for the microblaze architecture.
Signed-off-by: Neal Frager <neal.frager at amd.com>
---
V1->V2:
- builds a bare-metal gcc toolchain instead of requiring an external
microblaze toolchain
V2->V3:
- corrected custom cflags option
- added support for xilinx_v2022.2 version
- added zynqmp-firmware.hash
V3->V4:
- no changes
V4->V5:
- reduced all lines to <80 chars
V5->V6:
- migrated to toolchain-bare-metal-buildroot
V6->V7:
- removed patch numbers
- changed dependency to toolchain-bare-metal-buildroot
- removed hash since version is configurable
V7->V9:
- no changes
V9->V10:
- removed patches for supporting versions older than xilinx_v2023.2
V10-V11:
- set default BR2_TOOLCHAIN_BARE_METAL_BUILDROOT_ARCH to
"microblazeel-xilinx-elf" to avoid stand-alone build failure
