mii: add read-modify-write option to mii command
When accessing PHY registers it is often desirable to only update
selected bits, so it is necessary to first read the current value
before writing back an modified value with the relevant bits
updated.
To simplify this and to allow such operations to be incorporated
into simple shell scripts propose adding a 'modify' option to the
existing mii command, which takes a mask indicating the bits to
be updated in addition to a data value containing the new bits,
ie, <updated> = (<data> & <mask>) | (<current> & ~<mask>).

net: phy: realtek: Disable interrupt on Realtek Ethernet PHY drivers
Some Realtek Ethernet PHYs, like RTL8211D(G/N) and RTL8211E(G), have
interrupts enabled by default. If the interrupt is not treated later by
the OS and the PHY's interrupt line is enabled and shared with other
interrupts, the system will get an interrupt storm. This patch disables
the interrupt for PHY devices that use one of the current Realtek
Ethernet PHY drivers. Some of Realtek Ethernet PHYs, such as RTL8211B(L)
have the interrupt masked. In this case, the functionality of the PHY
should not be afected since this patch brings INER and INSR registers to
their default values.

powerpc/mpc8641hpcn: Move environment to avoid conflict
U-Boot on this board grew a long time ago past the 384 KiB that
it reserves for the U-Boot image, before the environment. Thus,
saveenv overwrites the U-Boot image and bricks the board.
I tried to find out when U-Boot grew beyond this point, but there is a
long stretch in the history where this board did not build -- and
AFAICT when it did fit in 384 KiB, it was missing vital features such
as fdt support. Turning off CONFIG_VIDEO was not enough to make it
fit. Thus, I don't think we have any choice other than to move the
environment.

powerpc/mpc85xx: Remove some dead code
U-Boot does not have system calls (the services it exposes to
standalone commands use a different mechanism), so the syscall handler
is dead code. It's also broken code, as it assumes it is located at
0xc00 -- while even before the patch to stop relocating exception
vectors to 0, U-Boot had the syscall at 0x900.
The critical and machine check return paths are never called -- the
regular exception return path is used instead, which works because
xSRR0/1 have already been saved and can be restored via the regular
SRR0/1 (we don't care too much in U-Boot about taking a critical/mcheck
inside another exception prolog/epilog).
Also remove a few other small unused functions.

Booke does not require exception vectors to be located at address zero.
U-Boot was doing so anyway, simply because that's how it had been done

address zero, the exception vectors have been overwritten -- which
makes it difficult to diagnose a crash that happens after that point.

buildman: Adjust the 'aborted' heuristic for writing output
At present buildman tries to detect an aborted build and doesn't record a

does not mark the build as done. Without this option, buildman would never
retry the build unless -f/-F are provided. The effect is that aborting the
build creates 'fake errors' on whatever builds buildman happens to be
working on at the time.
Unfortunately the current test is not reliable and this detection can
trigger if a required toolchain tool is missing. In this case the toolchain
problem is never reported.
Adjust the logic to continue processing the build result, mark the build as
done (and failed), but with a return code which indicates that it should be
retried.
The correct fix is to fully and correctly detect an aborted build, quit
buildman immediately and not write any partial build results in this case.
Unfortunately this is currently beyond my powers and is left as an exercise
for the reader (and patches are welcome).
