# Renesas R-Car Generation 2 SOCs
# - There are a combination of Cortex-A15s and Cortex-A7s for each Gen2 SOC
# - Each SOC can boot through any of the, up to 2, core types that it has
#   e.g. H2 can boot through Cortex-A15 or Cortex-A7

# Supported Gen2 SOCs and their cores:
# H2:  Cortex-A15 x 4, Cortex-A7 x 4
# M2:  Cortex-A15 x 2
# V2H: Cortex-A15 x 2
# M2N: Cortex-A15 x 2
# E2:                  Cortex-A7 x 2

# Usage:
# There are 2 configuration options:
# SOC:       Selects the supported SOC. (Default 'H2')
# BOOT_CORE: Selects the booting core. 'CA15', or 'CA7'
#            Defaults to 'CA15' if the SOC has one, else defaults to 'CA7'
