From: Alper Nebi Yasak Date: Mon, 7 Feb 2022 22:08:07 +0000 (+0300) Subject: binman: Convert FIT entry type to a subclass of Section entry type X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=f3078d4ea707931c2307a623ecf6e4d215b413d5;p=u-boot.git binman: Convert FIT entry type to a subclass of Section entry type The binman FIT entry type shares some code with the Section entry type. This shared code is bound to grow, since FIT entries are conceptually a variation of Section entries. Make FIT entry type a subclass of Section entry type, simplifying it a bit and providing us the features that Section implements. Also fix the subentry alignment test which now attempts to write symbols to a nonexistent SPL ELF test file by creating it first.
