Some platforms might expect the header of the image to be a certain
platform specific blob. This patch adds an ability to insert an
arbitrary size header in the binary blob, if so desired, the intention
is to have the platform specific tools to postprocess the image and
replace the header with sensible data.
Ideally we should be able to produce an image which is mapped to start
at an offset to the FLASH_BASE, but the macros in ec.S.lds files are
way too smart for this.
BRANCH=none
