Subject: [PATCH RESEND master] PBL: fdt: fix /memory parsing when #address-cells != #size-cells
Date: Mon, 30 May 2022 09:41:02 +0200	[thread overview]
Message-ID: <20220530074102.632341-1-a.fatoum@pengutronix.de> (raw)

Due to a typo, this code assumed so far ignored #size-cells and assumed
it to be equal to #address-cells. This breaks using the
barebox-dt-2nd.img with some 64-bit device trees like the Raspberry Pi's.

Fixes: ffb0344b7410 ("ARM: Add generic device tree 2nd stage support")
Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de>

Sent originally as part of the Raspberry Pi 4 support patch series.
Split it out, so it can go into master independently.
