Subject: cbfs: Use void * for the position pointers
X-Git-Url: http://git.dujemihanovic.xyz/img/static/git-favicon.png?a=commitdiff_plain;h=e82ab51bafecef063a081851d592fe82b680d50f;p=u-boot.git

cbfs: Use void * for the position pointers

It doesn't make sense to use u8 * as the pointer type for accessing the
CBFS since we do not access it as bytes, but via structures. Change it to
void *, which allows us to avoid a cast.
