[OpenWrt-Devel] [PATCH] brcm47xx: explicitly select CPU_MIPS32_R2 and CPU_MIPSR2 for mips74k

[Nathan Hintz]

The mips74k subtarget of brcm47xx configures gcc to compile for mips32r2;
however, the generated kernel config for 3.14 and later kernels ends up
with CPU_MIPS32_R1 and CPU_MIPSR1 selected.  The generated kernel config
for the 3.10 kernel (Barrier Breaker) properly selected CPU_MIPS32_R2 and
CPU_MIPSR2.  Modify the default kernel config for mips74k to explicitly
select CPU_MIPS32_R2 and CPU_MIPSR2.
