Subject: keystone2: keystone_nav: don't use hard addresses in netcp_pktdma
X-Git-Tag: v2015.01-rc1~125^2~47
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=ed948e2959acbad5289de1c733b3aeddd93208fe;p=u-boot

keystone2: keystone_nav: don't use hard addresses in netcp_pktdma

Use definitions in netcp_pktdma instead direct addresses.
The definitions can be set specifically for SoC, so there
is no reason to check SoC type while initialization.
