[-- Attachment #1: Type: text/plain, Size: 9032 bytes --]
BCM63138 is an ARM A9 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, peripheral timer and
Broadcom uart.
This SoC is supported in the linux-next git repository so the dts and
dtsi files are stripped down version of linux copies with mininum blocks
needed by u-boot.
The u-boot image can be loaded from flash or network to the entry
point address in the memory and boot from there.
This patch applies on top of the my previous patch [1] and depends
on the timer support from patch [2].
