qemumips: Use 34Kf CPU emulation
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>
