From 41c65ce44c3fad473102c92d569cb2c134ae9059 Mon Sep 17 00:00:00 2001 From: William Zhang Date: Mon, 1 Aug 2022 11:39:21 -0700 Subject: arm: bcmbca: add bcm63178 SoC support BCM63178 is an ARM A7 based DSL Broadband SoC. It is part of the BCA (Broadband Carrier Access origin) chipset family so it's added under ARCH_BCMBCA platform. This initial support includes a bare-bone implementation and dts with CPU subsystem, memory and ARM PL011 uart. This SoC is supported in the linux-next git repository so the dts and dtsi files are copied from linux with minor fix-up that needs to be upstreamed to linux as well. The u-boot image can be loaded from flash or network to the entry point address in the memory and boot from there.
