[PATCH-for-8.0 v2 00/11] hw/mips/malta: Generate nanoMIPS bootloader with bootloader generator API

[Philippe Mathieu-Daudé]

Bernhard posted his "Consolidate PIIX south bridges" v3 series:
20221204190553.3274-1-shentey@gmail.com/">https://lore.kernel.org/qemu-devel/20221204190553.3274-1-shentey@gmail.com/

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/20221027204720.33611-3-philmd@linaro.org/
and apply Bernhard's consolidation.

Since v1:
- addressed review comments
- generate JALRc
- split write_bootloader_nanomips() convertion in 5 parts
- use bl_gen_jump_kernel()
- merge common code to bl_setup_gt64120_jump_kernel()
