From e6e3b9d7b55ce2563f9da0b5991605f15bd38163 Mon Sep 17 00:00:00 2001 From: Ricardo Salveti Date: Thu, 20 Jan 2022 16:17:30 -0300 Subject: [PATCH] xilinx: common: change bootm_size to not go beyond ram_top The available ram can be limited by ram_top as that depends on the reserved memory nodes provided by the device-tree (via board_get_usable_ram_top), so make sure to respect ram_top when setting up bootm_size to avoid overlapping reserved memory regions (e.g. memory used by OP-TEE). The same logic is available in env_get_bootm_size when bootm_size is not defined by the default environment.
