Subject: mpc86xx: Add generic POST word read/write support
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=65f23519d65f56a3a894fcf4d748e5e96ef7166d;p=u-boot.git

mpc86xx: Add generic POST word read/write support

The PIC's TFRR register doesn't affect hardware and is generally unused,
so use as storage for the POST word.
