Subject: net: zynq_gem: Use wait_for_bit with non breakable
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=dea004e41a6d1aa8ebf668c450962db45a41b373;p=u-boot.git

net: zynq_gem: Use wait_for_bit with non breakable

Use wait_for_bit to be non breakable as using it with
breakable causes issue of un interruptible auto negotiation.
This is due to the ctrlc pressed will taken for wait_for_bit()
abort during phy_read() and hence not coming out of
auto negotiation.
