Subject: [PATCH v2 14/29] ARM: lds: add support for a 2nd CSF area
Date: Tue, 17 Oct 2023 16:51:16 +0200 [thread overview]
Message-ID: <20231017145131.3069283-15-m.felsch@pengutronix.de> (raw)
In-Reply-To: <20231017145131.3069283-1-m.felsch@pengutronix.de>
Extend the CSF area to be able two store two CSF slots. The 2nd CSF slot
is required in case of FlexSPI HAB boot support. The first slot is used
for the MMC-IVT + barebox-pbl; the 2nd slot is used for the FlexSPI-IVT
+ barebox-pbl. This is necessary because of the fact that the HAB ROM
code requires that the IVT is signed as well.
Make the 2nd CSF slot optional since early SRAM space is limited and 4K
can make a difference here.
Please check the documentation for a more detailed information about the
i.MX8M image layout.
