# Renesas R-Car Generation 3 SOCs
# - There are a combination of Cortex-A57s, Cortex-A53s, and Cortex-R7 for each Gen3 SOC
# - Each SOC can boot through any of the, up to 3, core types that it has
# e.g. H3 can boot through Cortex-A57, Cortex-A53, or Cortex-R7
# Supported Gen3 SOCs and their cores:
# H3: Cortex-A57 x 4, Cortex-A53 x 4, Cortex-R7 x 2 (Lock-Step)
# M3W: Cortex-A57 x 2, Cortex-A53 x 4, Cortex-R7 x 2 (Lock-Step)
# M3N: Cortex-A57 x 2, Cortex-R7 x 2 (Lock-Step)
# V3H: Cortex-A53 x 4, Cortex-R7 x 2 (Lock-Step)
# V3M: Cortex-A53 x 2, Cortex-R7 x 2 (Lock-Step)
# E3: Cortex-A53 x 1, Cortex-R7 x 2 (Lock-Step)
# D3: Cortex-A53 x 1
# Usage:
# There are 2 configuration options:
# SOC: Selects the supported SOC. (Default 'H3')
# BOOT_CORE: Selects the booting core. 'CA57', 'CA53', or 'CR7'
# Defaults to 'CA57' if the SOC has one, else defaults to 'CA53'
