When CONFIG_DM_ETH is set, we assemble the device path properly with a
full device hierarchy. Our helper function dp_fill() even put the MAC
node itself in it for us.
However, for non-DM compatibility we also have code in that added the
MAC node manually. That code now runs on top of the existing MAC node:
Handle 0x3db2f6b0
/HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]
/USBClass(0,0,9,0,0)/USBClass(424,9514,9,0,2)/MacAddr(b8:27:eb:e1:81:47,1)
/MacAddr(b8:27:eb:e1:81:47,57)/EndEntire
We obviously don't need the additional node and in fact, grub chokes on
it and fails to match the DP against the ethernet device node. So this
patch moves the additional MAC node into the non-DM code path:
Handle 0x3db3fde0
/HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ]
/USBClass(0,0,9,0,0)/USBClass(424,9514,9,0,2)/MacAddr(b8:27:eb:e1:81:47,1)
/EndEntire
While at it, we also mark the non-DM MAC node as ethernet.

The GOP path was optimized, but still not as fast as it should be. Let's
push it even further by trimming the hot path into simple 32bit load/store
operations for buf->vid 32bpp operations.
Signed-off-by: Alexander Graf <agraf@suse.de>
We usually try to compile for size, not for speed. Unfortunately with the
more powerful GOP infrastructure to handle all sorts of GOP operations, we
end up slowing down our copying hot path quite a lot.
So this patch moves the 4 possible GOP operation modes into separate
functions which call a common function again. The end result of that is
more optimized code that can properly do constant propagation throughout
its switch() statements and thus removes compares in the hot path.
