U-Boot nowadays also uses kconfig, so we can handle config fragments like we do for barebox/busybox/linux. Signed-off-by: Peter Korsgaard <peter@korsgaard.com> Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>

There are two possibilities when preparing an image writable to
|

NAND flash:
|
|
1) The NAND was not written at all yet or the BCB (Boot Control
|
|
Blocks) is broken. In this case, the NAND image 'u-boot.nand'
|
|
needs to written.
|
|
2) The NAND flash was already written with a good BCB. This
|
|
applies after 'u-boot.nand' was correctly written. There is no
|
|
need to write the BCB again. In this case, the bootloader can be
|
|
upgraded by writing 'u-boot.sb'.
|
|
|
|
To satisfy both cases, the 'u-boot.nand' image obtained from
|
|
mxsboot as well as the U-Boot make target 'u-boot.sb' are copied
|
|
to the binaries directory.
