[PATCH-for-8.0,0/7] hw/mips/malta: Generate nanoMIPS bootloader with bootloader generator API

Message

Bernhard posted his "Consolidate PIIX south bridges" v3 series:
https://lore.kernel.org/qemu-devel/[e-mail]/

However in order to simplify it, on the Malta board we need to set
the PIIX IRQC[A:D] routing values via the embedded bootloader (used
when no external BIOS is provided). Jiaxun added a "bootloader
generator API" for 32-bit wide instructions, and we use it in the
write_bootloader() function.
This series provides the nanoMIPS equivalent generated instructions
and update the write_bootloader_nanomips() function.
That allow fixing the TODO left in
https://lore.kernel.org/qemu-devel/[e-mail]/
and apply Bernhard's consolidation.

Please review,

Phil.
