[v9] Add nanoMIPS support to QEMU

[Qemu-devel] [PATCH v9 58/84] elf: On elf loading, treat both EM_MIPS and EM_NANOMIPS as legal for MIPS

Posted by Aleksandar Markovic 7 years, 2 months ago

From: Aleksandar Rikalo <arikalo@wavecomp.com>

Modify load_elf32()/load_elf64() to treat EM_NANOMIPS as legal as
EM_MIPS is.
