    How hard are the microblaze patches going to be to apply?


Alex is out today but the Microblaze gcc and binutils are based off versions Xilinx has
patches for. Right now, the microblaze is using this.

tools/rtems-xilinx-binutils-2.36
tools/rtems-xilinx-gcc-10-newlib-head

The first question is what's the latest gcc Xilinx has patches for.
It seems that the MicroBlaze support is not that well maintained in the 
upstream projects, for example:
https://support.xilinx.com/s/question/0D54U00006lA691SAC/microblaze-gcc-needs-proper-lra-support?language=en_US

I guess the trend is to use RISC-V soft cores instead.
