PATCH v2 1/2 boot/uboot: add support for i.MX28 SD format

From: Vincent Stehl? <[email protected]>

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.]

PATCH v2 2/2 config: Add defconfig for Freescale i.MX28 EVK

In reply to Arnout Vandecappelle (Essensium/Mind)

From: Vincent Stehl? <[email protected]>

The i.MX28 Evaluation Kit (or EVK) is Freescale's evaluation board based on the i.MX287 Applications Processor.

This defconfig is based on mainline u-boot and Linux kernel.

Also, we add an SD card creation script and documentation, shamelessly based on the ones for i.MX5/6 by Luca Ceresoli.

[Arnout: fixate U-Boot and kernel (headers) versions]

We use a manually specified custom version 3.19.2 of the linux kernel for i.MX28, but linux-headers defaults to a 2.6.x family.

Select custom headers family 3.19.x explicitely, to repair linux-headers "build".
