Subject: binman: bintool: move version check implementation into bintool class
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=723a63eeec3ee22d63006dcae593d395698fa55c;p=platform%2Fkernel%2Fu-boot-spacemit.git

binman: bintool: move version check implementation into bintool class

Version checking has nothing specific to compression/decompression tools
so let's move it to the Bintool class.
