Subject: target-microblaze: Move TCG initialization to MicroBlazeCPU initfn
X-Git-Tag: v1.5.0-rc0~672^2~26
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=cd0c24f9095b1f825210bb9d9f99532c78668074;hp=1cc896195bae54d7a5f48f9032037d8f6f65abd5;p=qemu.git

target-microblaze: Move TCG initialization to MicroBlazeCPU initfn

Split off TCG initialization from cpu_mb_init() into mb_tcg_init() to
call it from the initfn.

Ensures that a QOM-created MicroBlazeCPU is usable.
