Subject: binman: Add DecompressData function to entry class
X-Git-Tag: v2022.10~41^2~14
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=204a27bbb222c61bf5aaecbf7e00a5a8aa835bf9;p=platform%2Fkernel%2Fu-boot.git

binman: Add DecompressData function to entry class

Add a DecompressData function to entry class to allow override in child
classes and to centralize the compress and decompress in a single class.
