Inform the EFI subsystem that the framebuffer memory is reserved.

Without the patch the AllocatePool boot service allocates memory from the framebuffer which will will be overwritten by screen output.

Should this patch be merged into v2018.03 release or can it wait?

Hello Anatolij,

v2018.05 is fine. The problem will become visible in more cases with

[PATCH 1/1] efi_loader: efi_allocate_pages is too restrictive https://patchwork.ozlabs.org/patch/881055/ https://lists.denx.de/pipermail/u-boot/2018-March/321840.html

which is also pending.

Heinrich
