[PATCH v4 00/12] Resolve issues with booting distros on x86

[Simon Glass]

This little series reprises the EFI-video fix, fixes a USB problem and
enables a boot script for coreboot.

It also moves to truetype fonts for coreboot and qemu-x86, since the
menus look much better and there are no strong size constraints.

With these changes it is possible to boot a Linux distro automatically
with U-Boot on x86, including when U-Boot is the second-stage
bootloader.

Changes in v4:
- Don't rename the legacy-USB functions
- Add a bit more detail to the comment
- Use a Kconfig option

Changes in v3:
- Add new patch to refactor mmc prep to allow a different scan
- Add missing word 'function' in the commit message
- Clear the screen before booting
- Add new patch to drop unnecessary truetype operations from SPL
- Add new patch to enable truetype fonts in coreboot
- Add new patch to enable truetype fonts in qemu-x86 and qemu-x86_64

Changes in v2:
- Rebase to -next
- Add some more comments to the header file
- Add fixes tag
- Add new patch to add a return code to bootflow menu
- Add new patch to add a coreboot boot script
- Add new patch to avoid unbinding devices in use by bootflows
