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