[Buildroot] [PATCH v2 1/2] boot/uboot: add support for i.MX28 SD format
Arnout Vandecappelle (Essensium/Mind)

Sun Mar 22 13:25:14 UTC 2015
From: Vincent Stehlé <vincent.stehle at freescale.com>
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.]
