From mboxrd@z Thu Jan 1 00:00:00 1970 From: Siarhei Siamashka Date: Mon, 5 Sep 2016 06:36:10 +0300 Subject: [U-Boot] [PATCH] ARM: Respect CONFIG_SPL_STACK define in lowlevel_init.S Message-ID: <1473046570-13795-1-git-send-email-siarhei.siamashka@gmail.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 SPL and U-Boot proper may use different initial stack locations, which are configured via CONFIG_SPL_STACK and CONFIG_SYS_INIT_SP_ADDR defines. The lowlevel_init.S code needs to handle this in the same way as crt0.S Without this fix, setting the U-Boot stack location to some place, which is not safely accessible by the SPL (such as the DRAM), causes a very early SPL deadlock.
