[PATCH 1/2] Add comp_copy function for use with CONFIG_IMAGE_COMPRESSION_NONE

Sascha Hauer s.hauer at pengutronix.de
Wed Sep 14 01:21:52 PDT 2016


The Makefile compression commands all append the size of the
uncompressed image. With CONFIG_IMAGE_COMPRESSION_NONE simply
'shipped' is used which does not append the size. Add and use
a special comp_copy function which adds the size. This helps
us to get the uncompressed image size in the startup code later.
