[PATCH 1/5] arm: bcmbca: add bcm63158 SoC support under CONFIG_ARCH_BCMBCA
William Zhang

Fri Aug 12 01:17:53 CEST 2022
BCM63158 is a Broadcom B53 based DSL Gateway SoC. It is part of the
BCA (Broadband Carrier Access origin) chipset family. Like other
Broadband SoC, this patch adds it under CONFIG_BCM63158 chip
config and CONFIG_ARCH_BCMBCA platform config.
This initial support includes a bare-bone implementation and the
original dts is updated with the one from linux next git repository.
The u-boot image can be loaded from flash or network to the entry
point address in the memory and boot from there to the console.
