Subject: [PATCH] resource: change MEMATTRS_NORMAL to MEMATTR_WB
Date: Mon, 15 Dec 2025 09:36:33 +0100 [thread overview]
Message-ID: <20251215083635.2329721-1-a.fatoum@pengutronix.de> (raw)
Other EFI loaders (EDK-II, U-Boot) only set WB (Write-Back) for normal
memory. Let's follow suit for barebox.
This introduces no functional change yet, as these attributes will only
be put to use with the incoming EFI loader support.
