Subject: [PATCH v2 04/13] ARM: lds: Add SoC specific sections to go before .text_head_prologue
Date: Thu, 25 May 2023 01:43:19 +0200	[thread overview]
Message-ID: <20230524234328.82741-5-jmaselbas@zdiv.net> (raw)
In-Reply-To: <20230524234328.82741-1-jmaselbas@zdiv.net>

On sunxi platforms the boot rom (BROM) looks for a specific header which
will also be loaded in memory, causing pbl, or barebox, image not loaded
at the expected BASE addresse. This also cause an issue with relocatable
pbl: instruction used for relocation expect the image to be aligned on a
4K page boundary.

The proposed solution here is to allow to soc specific section to be put
in the very begging of the .text section, before anything else.
