This is the initial attempt to support booting SeaBIOS from U-Boot.
This is tested: - On Intel Crown Bay board with a PCIe graphics card, booting SeaBIOS then chain-loading a GRUB on a USB drive, then Linux kernel finally. - On QEMU x86 target with U-Boot chain-loading SeaBIOS to install/boot a Windows XP OS.
This series is available on u-boot-x86/seabios-working.
