[U-Boot] [PATCH 0/1] board: arm: Add support for Broadcom BCM7445D0

[Thomas Fitzsimmons]

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
