Subject: fsl/pcie: Change 'no link' to 'undetermined' for pcie endpoint
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=32514d259bf37cc92872aeb0624b75f600e7fb3a;p=u-boot.git

fsl/pcie: Change 'no link' to 'undetermined' for pcie endpoint

Even u-boot boots up, the pcie link may not setup correctly when
Freescale SOC acts as endpoint.
So change the link status from 'no link' to 'undetermined' to
reduce the confusion.
The link status can check from host side eventually.
