Subject: binman: Write the original input fdtmap to a file
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=96b6c506ca162b97ece5a59c0d2619173e6bfad8;p=u-boot.git

binman: Write the original input fdtmap to a file

When reading an image in, write its fdtmap to a file in the output
directory. This is useful for debugging. Update the 'ls' command to set up
the output directory; otherwise it will fail.
