boot/uboot: add support for i.MX28 SD format
Allow to generate u-boot.sd, Freescale i.MX28 SB format with a header for booting from an SD card. U-boot includes an mxsboot tool to generate this format, starting from v2011.12. See u-boot doc/README.mxs (or doc/README.mx28_common before 2013.07). [Arnout: - Wrap Config.in help text at 72 columns. - Remove v from U-Boot version specifier. - Refer to different README name before 2013.07. - Depend on host-elftosb - Add comment to clarify sb -> sd conversion.] Signed-off-by: Vincent Stehlé <vincent.stehle@freescale.com> Tested-by: Jörg Krause <joerg.krause@embedded.rocks> Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> Acked-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> Reviewed-by: Jörg Krause <joerg.krause@embedded.rocks> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
