Commit Message

Neal Frager Jan. 31, 2024, 11:22 a.m. UTC 
This patch adds a new package for building gcc for a bare-metal toolchain.
The cpu architecture is defined by a toolchain-bare-metal virtual package.
While any cpu architecture could be used, the default configuration will be a
Xilinx microblaze little endian architecture, so that buildroot will be able
to build the microblaze firmware applications for zynqmp and versal.

V1->V2:
 - removed default enable to be replaced with toolchain select config
V2->V3:
 - no changes
V3->V4:
 - split tar instruction into multiple lines
 - replaced unnecessary =? with = for assignments
 - changed xlnx-rel-v2023.1.tar.gz hash to sha256
 - improved menuconfig help comment
V4->V5:
 - moved to upstream gcc without any xilinx patches
 - reduced all lines to <80 chars
 - added license files
V5->V6:
 - migrated to toolchain-bare-metal-buildroot
V6->V7:
 - removed Config.in and hard-coded version
 - added sysroot for newlib install
V7->V8:
 - no changes
V8->V9:
 - integrated changes from Thomas
