From 69259b83670661ad530442e1ebb788e96a7676cb Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 18 Jun 2018 17:23:12 +0200 Subject: [PATCH] efi: sandbox: Adjust memory usage for sandbox With sandbox the U-Boot code is not mapped into the sandbox memory range so does not need to be excluded when allocating EFI memory. Update the EFI memory init code to take account of that.
