Work around the CPU clock miscalculation on Au1000DA/HA/HB due the
sys_cpupll register being write-only, i.e. actually do what the comment
before cal_r4off() function advertised for years but the code failed at.
This is achieved by just giving user a chance to define the clock
explicitly in the board config. via CONFIG_SOC_AU1000_FREQUENCY option,
defaulting to 396 MHz if the option is not given...
The patch is based on the AMD's big unpublished patch, the issue seems to
be an undocumented errata (or feature :-)...

Split the device setup code in ps3_register_repository_device() in two
routines:
1. ps3_setup_static_device(), to handle the setup of static devices in the
PS3 repository, which can be __init,
2. ps3_setup_dynamic_device(), to handle the setup of storage devices that
may appear later in the PS3 repository.
This fixes a few section mismatch warnings.

Improve the debugging support of the PS3 bootwraper code:
o Increase the size of the PS3 bootwrapper overlay from 256 to 512 bytes to
allow for more debugging code in the overlay.
o Use the dot symbol to set the size of __system_reset_overlay. The
assembler will then emit an error if the overlay code is too big.
o Remove some unused instructions.
o Update the text describing the PS3 bootwrapper overlay.
o Add a check for null pointer writes.
o Change hcall return value from s64.

The hardware team changed some things that were taken as being common to
all ns9xxx processors up to now.
This patch addresses:
- irqs: s/IRQ_/IRQ_NS9360_/
- system module registers: some registers are still general, their
definition lives now in include/asm-arm/arch-ns9xxx/regs-sys-common.h.
The ns9360 specific ones are in .../regs-sys-ns9360.h
As a result ns9360_systemclock cannot be static inline any more as its
definition needs regs-sys-ns9360.h. This becomes a real problem when
adding support for ns9215 as this will need regs-sys-ns9215.h and
including both files will not work. For the same reason
ns9360_reset() is now non-inline and gpio functions live in their own
file.
- register mapping: s/ns9xxx_map_io/ns9360_map_io/
- timer registers: move time.c to time-ns9360.c;
s/ns9xxx_timer/ns9360_timer/
Signed-off-by: Uwe Kleine-König <Uwe.Kleine-Koenig@digi.com>
- add all available mach types for ns9xxx even if the corresponding

Some IOMMUs allocate memory areas spanning LLD's segment boundary limit. It
forces low level drivers to have a workaround to adjust scatter lists that the
IOMMU builds. We are in the process of making all the IOMMUs respect the
segment boundary limits to remove such work around in LLDs.
SPARC64 IOMMUs were rewritten to use the IOMMU helper functions and the commit
89c94f2f70 made the IOMMUs not allocate memory
areas spanning the segment boundary limit.
However, SPARC64 IOMMUs allocate memory areas first then try to merge them
(while some IOMMUs walk through all the sg entries to see how they can be
merged first and allocate memory areas). So SPARC64 IOMMUs also need the
boundary limit checking when they try to merge sg entries.

I believe http://bugzilla.kernel.org/show_bug.cgi?id=10318 is a false
positive. There's no way in which networking will be using highmem pages
here, so it won't be taking the KM_USER0 kmap slot, so there's no point in
performing these checks.
