[PATCH 06/12] binman: Convert mkimage to Entry_section

Simon Glass sjg at chromium.org
Wed Jun 28 13:41:39 CEST 2023


From: Marek Vasut <marex at denx.de>

This is needed to handle mkimage with inner section located itself in a
section.

Signed-off-by: Marek Vasut <marex at denx.de>
Use BuildSectionData() instead of ObtainContents(), add tests and a few
other minor fixes:
