From: Heinrich Schuchardt Date: Mon, 14 Aug 2023 05:50:53 +0000 (+0200) Subject: efi_loader: fix efi_add_known_memory() X-Git-Tag: v2023.10~36^2~1 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b571b3acdaa43b90de3bc7540f13c02b1ee86b8e;p=platform%2Fkernel%2Fu-boot.git efi_loader: fix efi_add_known_memory() In efi_add_known_memory() we currently call board_get_usable_ram_top() with an incorrect value 0 of parameter total_size. This leads to an incorrect value for ram_top depending on the code in board_get_usable_ram_top(). Use the value of gd->ram_top instead which is set before relocation by calling board_get_usable_ram_top().
