From 2c03915322ede112030fcfb8097d4697b92fcc2f Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Mon, 13 Feb 2023 13:11:28 +0100 Subject: [PATCH] fix(zynqmp): fix DT reserved allocated size BL31_LIMIT is not size but reserved node reg property contains base address and size that's why BL31_LIMIT - BL31_BASE + 1 is correct size of reseved space for BL31. Also update warning message to cover that it is for BL31.
