From: Simon Glass <sjg@chromium.org> When running under QEMU U-Boot obtains its ACPI tables from QEMU, since it has the require information. This works well in most cases. QEMU also provides SMBIOS tables, but U-Boot doesn't currently use those on x86. This creates problems if a VM environment is expecting to see particular values (e.g. those which it passed to QEMU!) when booting. So this series switches QEMU on x86 to use those SMBIOS tables. Finally, there is a facility in EFI for showing a boot logo, via a BGRT table. QEMU does not provide this itself, so this series augments the ACPI tables with a new BGRT table containing a suitable logo.
