From f8209d30512d2e9c994d32cccfceda3a1e065cab Mon Sep 17 00:00:00 2001 From: William Zhang Date: Mon, 9 May 2022 09:28:02 -0700 Subject: arm: bcmbca: introduce the bcmbca architecture and 47622 SOC This is the initial support for Broadcom's ARM-based 47622 SOC. In this change, our first SOC is an armv7 platform called 47622. The initial support includes a bare-bone implementation and dts with ARM PL011 uart. The SOC-specific code resides in arch/arm/mach-bcmbca/ and board related code is in board/broadcom/bcmba. The u-boot image can be loaded from flash or network to the entry point address in the memory and boot from there.
