Hi William,

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.

Changes in v3:
- Remove the CONFIG_SYS_BAUDRATE_TABLE to use the u-boot default table

Changes in v2:
- Updated dts and dtsi files which are accpeted in linux-next upstream
- Changed CONFIG_SYS_TEXT_BASE to 0x0100 from 0x1000 to work
on boards with 256MB or less memory

[PATCH v3 1/1] arm: bcmbca: introduce the bcmbca architecture and 47622 SOC

2022-05-09 Thread William Zhang 
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.
