   4 Subject: [PATCH V2 04/13] 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 BMIPS5000.

  15 V1 -> V2:
  16  * Let the SYS_HAS_CPU_BMIPS* symbols select SYS_HAS_CPU_BMIPS instead of
  17    requiring users to select it
