Subject: linux-user/mips: Select M14Kc CPU to run microMIPS binaries
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=51c3aebfda6489b49cebef593a1ceb597cb97a7e;p=thirdparty%2Fqemu.git

linux-user/mips: Select M14Kc CPU to run microMIPS binaries

The M14Kc is our latest CPU supporting the microMIPS ASE.

Note, currently QEMU doesn't have 64-bit CPU supporting microMIPS ASE.
