   3 # Renesas R-Car Generation 2 SOCs
   4 # - There are a combination of Cortex-A15s and Cortex-A7s for each Gen2 SOC
   5 # - Each SOC can boot through any of the, up to 2, core types that it has
   6 #   e.g. H2 can boot through Cortex-A15 or Cortex-A7
   7
   8 # Supported Gen2 SOCs and their cores:
   9 # H2:  Cortex-A15 x 4, Cortex-A7 x 4
  10 # M2:  Cortex-A15 x 2
  11 # V2H: Cortex-A15 x 2
  12 # M2N: Cortex-A15 x 2
  13 # E2:                  Cortex-A7 x 2
  14
  15 # Usage:
  16 # There are 2 configuration options:
  17 # SOC:       Selects the supported SOC. (Default 'H2')
  18 # BOOT_CORE: Selects the booting core. 'CA15', or 'CA7'
  19 #            Defaults to 'CA15' if the SOC has one, else defaults to 'CA7'
