Subject: [U-Boot] [PATCH 0/1] board: arm: Add support for Broadcom BCM7445D0
Date: Sun, 6 May 2018 07:09:21 -0400 [thread overview]
Message-ID: <20180506110922.32469-1-fitzsim@fitzsim.org> (raw)
Hi,
This patch adds support for loading U-Boot on the Broadcom 7445D0 SoC,
as a third stage bootloader loaded by Broadcom's BOLT bootloader.
While this is only a partial port, it does enable some of U-Boot's
flexibility on this SoC, functionality beyond what BOLT provides.
Specifically, it brings:
- ext4 file system traversal
- support for loading FIT images
- advanced scripting
- support for FIT-provided DTBs instead of relying on the
BOLT-provided DTB
My team at Cisco is using a customized version of this port in
production. The same approach may work on other BCM7xxx boards, with
some configuration adjustments and memory layout experimentation.
Stefan Roese reviewed (off-list) some early revisions of these
changes. This patch is my attempt to rebase on the current U-Boot
master branch. I'm submitting it in case there is interest in
including this port in upstream U-Boot.
Thomas
