kexec-tools/0026-uImage-use-char-instead-of-unsigned-char-for-uImage_.patch

Subject: [PATCH 26/45] uImage: use 'char *' instead of 'unsigned char *' for
 uImage_probe()

... and friends. Again, PPC never cared about the difference, while
ARM had to add an explicit cast to work around it, which we can remove
now.
