   4 Subject: [PATCH 05/10] MIPS: bmips: merge CPU options into one option
   5
   6 Instead of treating each flavour as an exclusive CPU to select, make
   7 BMIPS the only option and let SYS_HAS_CPU_BMIPS* decide for which
   8 flavours to include support.
   9
  10 Run tested on BMIPS3300 and BMIPS4350, only build tested for BMIPS4380
  11 and BMISP5000.
