Public bug reported:
[ Impact ]
* The Michochip PolarFire SoC on the Icicle Kit is an FPGA with 4 + 1
RISC-V cores. So the memory map and some peripherals depend on the
FPGA design loaded.
* Microchip releases reference designs and are upstreaming support for
running Linux on it. Unfortunately the upcoming v2022.10 release
changes the memory layout compared to earlier versions, but v6.1-rc1
contains patches for it.
* We'd like to support the v2022.10 release and hopefully future versions
by backporting these changes.
[ Test Plan ]
* Update the Icicle Kit to the v2022.10 reference design and check that
the generic riscv64 kernel boots.
[ Where problems could occur ]
* Users who are running v2022.9 or older versions of the reference design
may have trouble booting, but the Icicle Kit was never officially
supported by Ubuntu.
