Few years ago we switched to using mips32r2 tunings for qemumips however the default CPU emulation still remained 24Kf which is not optimal for mips32r2 ISA for qemu [1], therefore switch to recommended 32Kf for CPU emulation when running qemu in system mode Boot time to console is ~1s faster with this setting, hopefully this should speed up qemumips in general [1] https://www.qemu.org/docs/master/system/target-mips.html#preferred-cpu-models-for-mips-hosts (From OE-Core rev: e68d2afd4a5529437824b5d6b9a2077c2fefd337) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
