Several fixes as well where the +1 was missing.
Done via coccinelle scripts like:
@@
struct resource *ptr;
@@
- ptr->end - ptr->start + 1
+ resource_size(ptr)
and some grep and typing.
Mostly uncompiled, no cross-compilers.

This will configure the platform data for the PL180, PL011 and
PL022 PrimeCells found in the U300 to use DMA with the generic
PrimeCell DMA engine for COH 901 318.

Just as it says, if this is merged along with the other patch, the
driver supports the U300 NAND flash interface.

This removes the quirks to clock the U300 VIC and timer by custom
hooks and moves the control out to the clock framework where it
belongs. This is possible now that clocks are available early.

This fixes a regression due to the new apb_pclk stuff in the U300
platform, makes it run by splitting the apb clock off the single
UART clocks. For the MMCI and PL022 clocks we don't split them:
these are actually hardwired to the same clock terminal and will
thus simply have a double reference count and will be referenced
twice.
We also move clock registration to .init_irq() so they are
available early enough for probing to be successful and remove the
earlier quirk to clock primecells during PrimeCell registration.

MACH_U300_BS26 doesn't exist in Kconfig, therefore removing all

This fixes a few bugs in the DMA configuration for the COH 901 318
DMA engine used in U300. It also removes the directional parameter
for each channel: separate DMA engine patches (submitted to the
DMA engine maintainer) switches that mechanism over to using
dynamic configuration of this, to handle bidirectional DMA
channels.

In particular, several occurances of funny versions of 'success',
'unknown', 'therefore', 'acknowledge', 'argument', 'achieve', 'address',

This changes the bus name of the U300 watchdog from just "wdog"
to "coh901327_wdog" which is used to match the corresponding
driver. This makes the watchdog probe properly.

This will fix some small issues with the COH 901 331 RTC driver:
- Interrupt is disabled after alarm so that we don't fire
multiple interrupts.
- We return 0 from the coh901331_alarm_irq_enable() ridding
a compile warning.
- We alter the name in the U300 device registry to match that
of the driver so they sucessfully resolve.

This adds a U300 board configuration for the PL022 SSP/SPI
PrimeCell driver recently merged to the 2.6.31-rc series.
Further it adds a dummy loopback SPI chip that can be used

the loopback mode of PL022.

This makes the VIC resume from suspend flagged IRQ:s identical to
the flags indicating all possible interrupts. This is perhaps not
the optimal setting but setting it to 0 makes the system suspend
and never come back again (all IRQ sources masked off).

This adds core support for the ST-Ericsson U300 series
platforms: U300, U330, U335 and U365. Supports memory
mappings, interrupt controller, system timer (clocksource
and clockevents), and binds to the existing drivers for
the PrimeCells used in this design: PL190 (VIC), PL180
(MMC/SD host) and PL011 (UART). This is intented to serve
as starting point for our mainling work, more patches to
follow.
