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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
