This bug is awaiting verification that the linux-azure/5.19.0-1017.18
kernel in -proposed solves the problem. Please test the kernel and
update this bug with the results. If the problem is solved, change the
tag 'verification-needed-kinetic' to 'verification-done-kinetic'. If the
problem still exists, change the tag 'verification-needed-kinetic' to
'verification-failed-kinetic'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Title:
  Support Icicle Kit reference design v2022.10

Status in linux package in Ubuntu:
  Invalid
Status in linux source package in Kinetic:
  Fix Released

Bug description:
  [ 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.
