Message

This patchset is to add toolchain feature detection for most MIPS CPUs
by adding more toolchain feature detections and fixing -march CFLAGS.

Thanks
Jiaxun

Jiaxun Yang (7):
  MIPS: Move various toolchain ASE check to Kconfig
  MIPS: Add toolchain feature dependency for microMIPS smartMIPS
  MIPS: Detect toolchain support of workarounds in Kconfig
  MIPS: Detect toolchain support of o32 ABI with 64 bit CPU
  MIPS: Remove cc-option checks for -march=octeon
  MIPS: Fallback CPU -march CFLAG to ISA level if unsupported
  MIPS: Limit MIPS_MT_SMP support by ISA reversion
