The MII_MODE bit of the FEC RCR register means xMII, i.e. 'not 7-wire', so set
it accordingly.
According to the xMII and 7-wire (aka GPSI) standards, full duplex should be
available on xMII, but not on 7-wire, so set FCE accordingly. The FEC may
support full duplex for 7-wire too, but the reference manual does not say that,

ehci-hcd: fix external buffer cache handling
Buffer coming from upper layers should be cacheline aligned/padded
to perform safe cache operations. For now we don't do bounce
buffering so getting unaligned buffer is an upper layer error.
We can't check if the buffer is properly padded with current
interface so just assume it is (consider changing with in the
future). The following changes are done:
1. Remove useless length alignment check. We get actual transfer
length not the size of the underlying buffer so it's perfectly
valid for it to be unaligned.
2. Move flush_dcache_range() out of while loop or it will
flush too much.
3. Don't try to fix buffer address before calling invalidate:
if it's unaligned it's an error anyway so let cache subsystem
cry about that.
4. Fix end buffer address to be cacheline aligned assuming upper
layer reserved enough space. This is potentially dangerous
operation so upper layers should be careful about that.

Microblaze will never use the ARCH_CPU_DTS substitution and we

programmed over a USB connection. On dev boards, this is typically entered
by holding down a "force recovery" button and resetting the CPU. However,
not all boards have such a button (one example is the Compulab Trimslice),
so a method to enter RCM from software is useful.
This change implements the command "enterrcm" to do this, and enables it
for all Tegra boards by default. Even on boards other than Trimslice,
controlling this over a UART may be useful, e.g. to allow simple remote
control without the need for mechanical button actuators, or hooking up
relays/... to the button.

Commit 896bbb5 "fdt: avoid bad MAKEALL status" added logic to capture
the result code from dtc by echoing $? to stdout and capturing it using
$(). However, dtc emits some diagnostics to stderr and some to stdout.
The diagnostics send to stdout ended up getting captured via $() rather
than being echo'd to the user. This caused those diagnostics to be passed
to the exit command, which would then fail with the following cryptic
error message:
/bin/sh: line 1: exit: too many arguments
Solve this by redirecting all dtc output to stderr so that $() does not
capture it. This allows the user to see the actual error message from dtc.
