# 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'
