[Buildroot] [PATCH 2/2] boot/uboot: allow to build multiple Uboot images

Petr Kulhavy brain at jikos.cz
Thu Sep 1 14:51:34 UTC 2016


Sometimes it is desired to build multiple U-boot images. E.g. one to save into
flash memory and one for serial load. This was not possible.

This change allows to select any combination of the target formats. They are
all copied to the image folder.
