Sometimes it is desired to build multiple U-boot images. E.g. one to save into flash memory and one for serial load. So far this was not possible. This change allows to select any combination of the target formats. They are all copied to the image folder. Signed-off-by: Petr Kulhavy <brain@jikos.cz> [Thomas: - Handle the BR2_TARGET_UBOOT_FORMAT_BIN, which wasn't handled, and therefore u-boot.bin was not copied when BR2_TARGET_UBOOT_FORMAT_BIN=y. - Rename UBOOT_BIN to UBOOT_BINS, since it can now contain multiple values.] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

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.
