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.
