The address prefix 00:90:4C is used by Broadcom in their initial
configuration. When a mac address with the prefix 00:90:4C is used all
devices from the same series are sharing the same mac address. To
prevent mac address collisions we replace them with a mac address based
on the base address. To generate such addresses we take the main mac
address from et0macaddr and increase it by two for the first wifi
device and by 3 for the second one. This matches the printed mac
address on the device. The main mac address increased by one is used as
wan address by the vendor code.

The reboot on the BCM47XX SoCs is done, by setting the watchdog counter
to 1 and let it trigger a reboot, when it reaches 0. Some devices with
a BCM4705/BCM4785 SoC do not reboot when the counter is set to 1 and
decreased to 0 by the hardware. It looks like it works more reliable
when we set it to 3. As far as I understand the hardware, this should
not make any difference, but I do not have access to any documentation
for this SoC.
It is still not 100% reliable.

This fixes a regression caused by commit
bb6c0bd3fd [MIPS: SB1: Fix excessive kernel
warnings.], that makes `-march=r5000' selected for compilation flags
rather than supposed `-march=sb1' with compilers that do not support the
ASE selection flags introduced with that change.
For example GCC 4.1.2 supports `-mips3d'/`-mno-mips3d' (and obviously
`-march=sb1'), however it does not support `-mdmx'/`-mno-mdmx'. As a
result the whole selection of flags fails and compilation resorts to using
`-march=r5000', meant for really old compilers indeed only.
It is always best to pick the flags individually unless we are absolutely
sure a set of flags was introduced to the toolchain together (`-march=sb1'
and `-mtune=sb1' would be a good example), and this change makes it happen
for CONFIG_CPU_SB1. Consequently the flags ultimately selected with GCC
4.1.2 are `-march=sb1 -Wa,--trap -mno-mips3d'

The generic version uses a variable length of u32 registers instead of u32/u64.
This allows easier support for "wider" registers without having to rewrite
everything.
This "generic" version is as fast as the old version in the best case
(i == next set bit), and twice as fast in the worst case in 64 bits.
Using a macro was chosen over a (forced) inline version because gcc generated
more compact code with the macro.
The change from (signed) int to unsigned int for i and to_call was intentional
as the value can be only between 0 and (width - 1) anyway, and allowed gcc to
optimise the code a bit further.

This patch introduces common clock framework integration for all
configurable on-chip clocks on Alchemy chips:
- 2 or 3 PLLs which generate integer multiples of the root rate 12MHz,
- 6 dividers which take one of the 3 PLLs as input and divide their
rate by either multiples of 2 or 1 (Au1300).
- another bank of up to 6 muxes which take either one of the 6
above dividers or one of the PLLs directly and divide their rate
further by 1, 2, 3 or 4.
- a few other sources which are used by onchip peripherals and are
informational.
This implementation will take the clock tree as it was set up
by boot firmware: all in-kernel boards should continue to work
without having to set up the clock tree in board code.
CLK_IGNORE_DISABLED will be removed once all drivers have been
converted.

Pull parisc fixes from Helge Deller:
"The major patch in here is one which fixes the fanotify_mark() syscall
in the compat layer of the 64bit parisc kernel. It went unnoticed so
long, because the calling syntax when using a 64bit parameter in a
32bit syscall is quite complex and even worse, it may be even
different if you call syscall() or the glibc wrapper. This patch
makes the kernel accept the calling convention when called by the
glibc wrapper.
The other two patches are trivial and remove unused headers, #includes
and adds the serial ports of the fastest C8000 workstation to the
parisc-kernel internal hardware database"
* 'parisc-3.16-5' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
parisc: drop unused defines and header includes
parisc: fix fanotify_mark() syscall on 32bit compat kernel
parisc: add serial ports of C8000/1GHz machine to hardware database
On parisc we can not use the existing compat implementation for fanotify_mark()
because for the 64bit mask parameter the higher and lower 32bits are ordered
differently than what the compat function expects from big endian
architectures.
Specifically:
It finally turned out, that on hppa we end up with different assignments
of parameters to kernel arguments depending on if we call the glibc
wrapper function
int fanotify_mark (int __fanotify_fd, unsigned int __flags,
uint64_t __mask, int __dfd, const char *__pathname);
or directly calling the syscall manually
syscall(__NR_fanotify_mark, ...)
Reason is, that the syscall() function is implemented as C-function and
because we now have the sysno as first parameter in front of the other
parameters the compiler will unexpectedly add an empty paramenter in
front of the u64 value to ensure the correct calling alignment for 64bit
values.
This means, on hppa you can't simply use syscall() to call the kernel
fanotify_mark() function directly, but you have to use the glibc
function instead.
This patch fixes the kernel in the hppa-arch specifc coding to adjust
the parameters in a way as if userspace calls the glibc wrapper function
fanotify_mark().
