This is copied from U-Boot v2014.10 and modified for use with
barebox:
- Add a main() function to make it a standalone tool
- Add option to pass in the prepare stage and bootloader
image as options. If the config file contains @PREP@ or
@BOOTLOADER@ the string will be replaced with the actual
image file passed via the -p and -b options.

We assumed that there is a special image format for SPI. This is not
the case. The AM33xx can boot either images generated with omap_signGP
or raw images which only have the image size and load address in front
of the image. Whether these images are booted from SPI or another
boot medium doesn't matter. The only special thing about SPI is that
the image is in big endian format.
- renames mk-am3xxx-spi-image.c to mk-omap-image.c as the image format
is not only supported by AM3xxx but also by the OMAP SoCs
- removes the option to specify the SoC
- introduces -s to build a big endian image
- detects if an image already is an image generated with omap_signGP
So the behaviour is like this:
raw image -> mk-omap-image -> prepend size/address -> image for SD/MMC
raw image -> mk-omap-image -s -> prepend size/address, big endian swap -> image for SPI
CH image -> mk-omap-image -> nothing, input == output
CH image -> mk-omap-image -s -> big endian swap -> image for SPI

Create up-to-date list of hostprogs and targetprogs based on Makefile.
Have this list sorted like the targets in the Makefile to ease maintenance.
Also move some leftovers from root .gitignore over here.

The Altera SoCFPGAs expect a simple header for their first stage
loaders. This adds a tool to generate images for the SoCFPGAs. The
header is either embedded into the image or optionally prepended
to the image. In this case code is added to jump over the image
header.

This tool is used with Marvell EBU SoC to trigger the UART boot mode
provided by the SoC BootROM, and push the bootloader image to the
target using the Xmodem protocol.
It has been taken from the U-Boot source code, with minor
modifications to make it work with Armada 370/XP platforms.

The Marvell EBU SoCs (Kirkwood, Armada 370, Armada XP) have a BootROM
that understand a specific image format, composed of a main header,
several extension headers and a paylod. This image can be booted from
NAND, SPI, SATA, UART, NOR, etc.
This patch adds a tool that allows to extract the components and
configuration of existing images, and to create new images.

The bootrom only reads an image if the correct checksum is present in the
header. The calculation is pretty simple:
sum over all words from 0x20 to 0x44
Two of this words are the image length. That is why the checksum can not be
calculated until barebox_image_size is known.
The easiest solution is a program that has to be run after make.

Booting from SPI on an AM35xx (and possibly other TI SOCs) requires
a special format:
- 32 bit image size in big-endian
- 32 bit load address in big-endian
- binary image converted from little- to big-endian
The mk-am35xx-spi-image tool converts barebox.bin to
this format.
