From c8da6513c054c150640e8ad12185bd53ae1852fc Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Thu, 9 Jul 2020 15:57:56 +0200 Subject: [PATCH] xilinx: Setup bootm variables On system with PL DDR which is placed before PS DDR in DT env_get_bootm_size() and env_get_bootm_low() without specifying bootm_low and bootm_size variables are taking by default gd->bd->bi_dram[0].start and gd->bd->bi_dram[0].size. As you see 0 means bank 0 which doesn't need to be PS ddr and even can be memory above 39bit VA which is what U-Boot supports now. That's why setup bootm variables based on ram_base/ram_size setting to make sure that boot images are placed to the same location as U-Boot is placed. This location should be by default location where OS can boot from.
