From c6e0073c0583f2557bcaf62333dab705e25e1e24 Mon Sep 17 00:00:00 2001 From: William Zhang Date: Fri, 5 Aug 2022 18:34:00 -0700 Subject: [PATCH] arm: bcmbca: add bcm63146 SoC support BCM63146 is a Broadcom B53 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. 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.
