From 51c533fdce75fbdec7de28a05a675a553d209bcb Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Mon, 28 Aug 2017 18:54:30 +0200 Subject: [PATCH] efi_loader: bootefi hello should use loadaddr Command 'bootefi hello' currently uses CONFIG_SYS_LOAD_ADDR as loading address. qemu machines have by default 128 MiB RAM. CONFIG_SYS_LOAD_ADDR for x86 is 0x20000000 (512 MiB). This causes 'bootefi hello' to fail. We should use the environment variable loadaddr if available. It defaults to 0x1000000 (16 MiB) on qemu_x86.
