Error: Opcode not supported on the processor: mips2 (mips2) 'sync'

Hi,

While compiling the openwrt project, i'm facing the "opcode not supported" errors as seen in the attached image.

FYI - The below changes are already present in the ev.c file.

Let me know if any other information is required.

Regards,
Bobby
