Subject: scripts/qemustart: update malta to use MIPS64 R2 cpu
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=5b3ff53ebd6846a0f03bfa29d9aa5d22a6a05bfb;p=openwrt%2Fstaging%2Fynezz.git

scripts/qemustart: update malta to use MIPS64 R2 cpu

Explicitly set the QEMU cpu type and support the MIPS R2 ISA, for both
64-bit and 32-bit targets. The later previously supported MIPS R2 by
implicit default.

This is needed after commit 93608697f3 ("malta: update MIPS64 ISA to R2"),
otherwise booting malta images with scripts/qemustart will hang.
