Subject: [PATCH] display5: Stop disabling device tree relocation
Date: Tue, 18 Nov 2025 12:03:56 -0600	[thread overview]
Message-ID: <20251118180356.591016-1-trini@konsulko.com> (raw)

Remove setting of fdt_high to ~0, which disables device tree relocation,
from the default environment. Doing so prevents U-Boot from correcting
problems such as having an unaligned device tree and leads to various
failure modes in the OS.

Signed-off-by: Tom Rini <trini@konsulko.com>

If there is some window of memory that must be used for where the device
tree is relocated to, bootm_low + bootm_size (or often just bootm_size)
or bootm_mapsize are the correct way do this. Please see
doc/usage/environment.rst for more details.
