Subject: patman: Update errors and warnings to use stderr
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=38fdb4cb35e9260a6aa78ffcfa68d39bfc3523de;p=u-boot.git

patman: Update errors and warnings to use stderr

When warnings and errors are produced by tools they should be written to
stderr. Update the tout implementation to handle this.
