Subject: e1000: fix PCI memory addressing
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f81ecb5d3300bf92d17302d3712f30585c182da9;p=project%2Fbcm63xx%2Fu-boot.git

e1000: fix PCI memory addressing

The Intel E1000 driver was making assumptions about the relationship between
some virtual, physical, and PCI addresses.

Also fix some bad usage of the DEBUGOUT macro
