+# Renesas RZ/G2 SOCs
+# - There are a combination of Cortex-A57s, Cortex-A53s, Cortex-A55, Cortex-R7
+# and Cortex-M33 for each SOC
+# - Each SOC can boot through the Cortex-A5x cores
+
+# Supported RZ/G2 SOCs and their cores:
+# RZ/G2H: Cortex-A57 x4, Cortex-A53 x4, Cortex-R7
+# RZ/G2M: Cortex-A57 x2, Cortex-A53 x4, Cortex-R7
+# RZ/G2N: Cortex-A57 x2,                Cortex-R7
+# RZ/G2E:                Cortex-A53 x2, Cortex-R7
+# RZ/G2L:                Cortex-A55 x2, Cortex-M33
+
+# Usage:
+# There are 2 configuration options:
+# SOC:       Selects the supported SOC. (Default 'G2L')
+# BOOT_CORE: Selects the booting core. 'CA57', 'CA53' or 'CA55'
