x-load is a first level bootloader for Texas Intruments OMAP
microprocessors (similar to the AT91Bootstrap application).
This bootstrap package is required on TI OMAP boards where
dataflash/nandflash or USB/RS232 is used to boot from. In
any of these cases the internal bootROM of the OMAP core is
used to boot the board with.

+ The X-Loader is a first level bootloader for Texas Intruments OMAP
+ microprocessors (similar to the AT91Bootstrap application). It is
+ used for booting these microprocessors from NAND-flash, MMC/SD-card,
+ USB or serial interfaces.

+config X_LOAD_VERSION
+ string
+ default 1.4.2-dirty
+ prompt "X-Loader version"
+ help
+ Enter the X-Loader version you want to build. Usally something like
"1.4.2"
+
+config X_LOAD_SERIES
+ prompt "patch series file"
+ string
+ default "series${PTXDIST_PLATFORMSUFFIX}"
+ help
+ This entry specifies a patch series file which has to live in
+ the kernel patches directory:
+
+ The series file contains lines with names of patch files which
+ are then being applied to the kernel.
+
+config X_LOAD_CONFIG
+ string
+ prompt "X-Loader config target"
+ help
+ The X-Loader make config target. Usually something like
+ "yourbox_config". See X-Loader's main Makefile for possible
+ configuration targets.
+
+config X_LOAD_MAKE_IFT
+ bool
+ prompt "Generate signed IFT file"
+ help
+ When this option is enabled, a so-called IFT file is generated. You
+ need a X-Loader source tree that supports this. This must know about
+ the make target 'ift' so ptxdist can do the following: "make ift".
+
+ In details you will need the tool signGP from
+ http://beagleboard.googlecode.com/files/signGP.c
