I don't know this port really well (and the AT91 family has been
orphaned and without active custodian for a long time), but it should
not touch the PHY (and especially not wait for a link) unless a
network command is being run in U-Boot.  There have been some
discussions about this topic recently (see for example thread starting
here: http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/76507).

Best regards,

Wolfgang Denk
