From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tim Harvey Date: Fri, 25 Sep 2020 08:08:35 -0700 Subject: [PATCH] imx8m: fix cache setup for dynamic sdram size Message-ID: <1601046515-30684-1-git-send-email-tharvey@gateworks.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de the mem_map structure containing the size of SDRAM is used in various cache functions in cache_v8.c thus we need to update it with the sdram size the board is configured with as well. Without this the cache functions do not get setup properly and can hang in the case where a board reports more SDRAM than defined in PHYS_SDRAM_SIZE.
