Subject: x86: Move fsp_prepare_mrc_cache() to fsp1 directory
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=22e0de355196f809d74bdc0c6e0e2c689caa515b;p=u-boot.git

x86: Move fsp_prepare_mrc_cache() to fsp1 directory

This function needs to be different for FSP2, so move the existing
function into the fsp1 directory. Since it is only called from one file,
drop it from the header file.
