This is a patch from Simon Glass. U-Boot clears the display
when it starts up, but was asking the VESA driver to do the
same, needlessly; this patch avoids the latter.
A further patch is also included, which provides a better
message when jumping into long mode on the SPL (64-bit) target,
dumping it on the serial console instead of using printf.

U-Boot was hanging on hardware, but not Qemu. This is because on
the machines tested, namely the X200 and E6230 laptops supported
in Libreboot, the UART was disabled from coreboot.
This U-Boot patch from Simon Glass works around the issue by
silently disabling the UART when it isn't there. Instead,
output is sent to the display and U-Boot no longer hangs.

It's a new experimental payload in Libreboot, so we may aswell
start with the very latest release of U-Boot.

Currently seems to stall when booted from the GRUB
payload, but works when booted from the SeaBIOS menu.
I also tested it as a standalone payload and it seems
to boot. Will test on hardware next, and start adding
it to more mainboards.
