Subject: [PATCH v2 2/8] configs: j7200_evm_r5: Used reserved memory in DDR for stack
Date: Tue, 7 Nov 2023 17:17:56 +0100 [thread overview]
Message-ID: <20231107161802.855154-3-thomas.richard@bootlin.com> (raw)
In-Reply-To: <20231107161802.855154-1-thomas.richard@bootlin.com>
From: Gregory CLEMENT <gregory.clement@bootlin.com>
When resuming from suspend to ram, we load again the DM firmware.
However, we have to be sure to not modify the memory used by
Linux.
Currently the SPL stack in DDR was in place that could be used by
Linux. Instead of it use a memory address that is located in a
reserved location that won't be used by Linux.
