[PATCH 0/5] arm64: bcmbca: add bcm63158 soc support

[William Zhang]

[-- Attachment #1: Type: text/plain, Size: 1220 bytes --]

This change adds the basic support for Broadcom's ARM64 based
Broadband SoC BCM63158. The initial support includes a bare-bone dts
for quad core ARM A53 with a ARM PL011 uart. Linux kernel image can be
built with the ARM64 defconfig.

[PATCH 3/5] arm64: dts: add dts files for bcmbca soc 63158

[William Zhang]

[-- Attachment #1: Type: text/plain, Size: 5413 bytes --]

Add dts for ARMv8 based broadband SoC BCM63158. bcm63158.dtsi is the
SoC description dts header and bcm963158.dts is a simple dts file for
Broadcom BCM963158 Reference board that only enable the UART port.

Yes it is the generic board id with only minimum hardware blocks(cpu, 
memory, uart) enabled for all BCM63158 based boards.  Specific board id 
can be added in the future with actual hardware blocks that are used on 
the board.
