Series fully reviewed.
v3:
- Do not rename loongarch_la464_initfn (rth)
- Added R-b
v2:
- Do no rename loongarch_cpu_get/set_pc (rth)
- Rebased Jiajie's patches for convenience
- Added rth's R-b
Jiajie, this series contains few notes I took while
reviewing your series adding loongarch32 support

Commit 228021f05e ("target/loongarch: Add core definition") sets
disas_set_info to loongarch_cpu_disas_set_info. Probably due to
a failed git-rebase, commit ca61e75071 ("target/loongarch: Add gdb
support") also sets it to the same value. Remove the duplication.

Extract loongarch64 specific code from loongarch_cpu_class_init()
to a new loongarch64_cpu_class_init().
In preparation of supporting loongarch32 cores, rename these
