Hey Bart,

Thanks for this!
Really helpful.

Just a tiny wee snag:

Acorn RiscPC is ARMv3, which sadly isn't supported anymore with gcc9.
So for compilation I had to modify Kconfig to select ARMv4:

diff --git a/arch/arm/mm/Kconfig b/arch/arm/mm/Kconfig
index 8355c3895894..22ec9e275335 100644
--- a/arch/arm/mm/Kconfig
+++ b/arch/arm/mm/Kconfig

+       select CPU_32v4 if ARCH_RPC
        select CPU_32v4 if !ARCH_RPC
        select CPU_ABRT_EV4
        select CPU_CACHE_V4WB

Cheers,

Hannes
