This is part of the effort moving peripheral registers outside of pxa-regs.h,
and using ioremap() make it possible the same IP can be re-used on different
processors with different registers space
As a result, the fixed mapping in pxa_map_io() is removed.
The regs-lcd.h can actually moved to where closer to pxafb.c but some of its
bit definitions are directly used by various platform code, though this is not
a good style.

If the user specified a fixed framebuffer address on the command line, it may
have been initialized already with a splash image or something, so we
shouldn't clear it.
Therefore, we should only initialize the framebuffer if we allocated it
ourselves. This patch also updates the AVR32 setup code to clear the
framebuffer if it allocated it itself, i.e. the user didn't provide a fixed
address or the reservation failed.
I've updated the at91 platform code as well so that it initializes the
framebuffer if it is located in SRAM, but I haven't tested that it actually
works.

Changes include:
1. rename MFP_LPM_WAKEUP_ENABLE into MFP_LPM_CAN_WAKEUP to indicate
the board capability of this pin to wakeup the system
2. add gpio_set_wake() and keypad_set_wake() to allow dynamically
enable/disable wakeup from GPIOs and keypad GPIO
* these functions are currently kept in mfp-pxa2xx.c due to their
dependency to the MFP configuration
3. pxa2xx_mfp_config() only gives early warning if MFP_LPM_CAN_WAKEUP
is set on incorrect pins
So that the GPIO's wakeup capability is now decided by the following:
a) processor's capability: (only those GPIOs which have dedicated
bits within PWER/PRER/PFER can wakeup the system), this is
initialized by pxa{25x,27x}_init_mfp()
b) board design decides:
- whether the pin is designed to wakeup the system (some of
the GPIOs are configured as other functions, which is not
intended to be a wakeup source), by OR'ing the pin config
with MFP_LPM_CAN_WAKEUP
- which edge the pin is designed to wakeup the system, this
may depends on external peripherals/connections, which is
totally board specific; this is indicated by MFP_LPM_EDGE_*
c) the corresponding device's (most likely the gpio_keys.c) wakeup
attribute:

- PGSR1 = 0x00000002;
- PGSR2 = 0x0001FC00;
- PGSR3 = 0x00001F81;
this is removed as low power state has already been encoded in
the pin configuration definitions.
Note: there is no specific reason for some of the GPIOs to drive
high in low power mode as indicated by the above setting, those
bits are ignored, and the result is validated to work.
2. the following code to configure GPIO wakeup is removed as this
is now totally handled by pxa2xx_mfp_config():

- PRER = 0x00000002;

Pin configuration on pxa{25x,27x} has now separated from generic GPIO
into dedicated mfp-pxa2xx.c by this patch. The name "mfp" is borrowed
from pxa3xx and is used here to alert the difference between the two
concepts: pin configuration and generic GPIOs. A GPIO can be called
a "GPIO" _only_ when the corresponding pin is configured so.
A pin configuration on pxa{25x,27x} is composed of:
- alternate function selection (or pin mux as commonly called)
- low power state or sleep state
- wakeup enabling from low power mode
The following MFP_xxx bit definitions in mfp.h are re-used:
- MFP_PIN(x)
- MFP_AFx
- MFP_LPM_DRIVE_{LOW, HIGH}
- MFP_LPM_EDGE_*
Selecting alternate function on pxa{25x, 27x} involves configuration
of GPIO direction register GPDRx, so a new bit and MFP_DIR_{IN, OUT}
are introduced. And pin configurations are defined by the following
two macros:
- MFP_CFG_IN : for input alternate functions
- MFP_CFG_OUT : for output alternate functions
Every configuration should provide a low power state if it configured
as output using MFP_CFG_OUT(). As a general guideline, the low power
state should be decided to minimize the overall power dissipation. As
an example, it is better to drive the pin as high level in low power
mode if the GPIO is configured as an active low chip select.
Pins configured as GPIO are defined by MFP_CFG_IN(). This is to avoid
side effects when it is firstly configured as output. The actual
direction of the GPIO is configured by gpio_direction_{input, output}
Wakeup enabling on pxa{25x, 27x} is actually GPIO based wakeup, thus
the device based enable_irq_wake() mechanism is not applicable here.
E.g. invoking enable_irq_wake() with a GPIO IRQ as in the following
code to enable OTG wakeup is by no means portable and intuitive, and
it is valid _only_ when GPIO35 is configured as USB_P2_1:
enable_irq_wake( gpio_to_irq(35) );
To make things worse, not every GPIO is able to wakeup the system.
Only a small number of them can, on either rising or falling edge,
or when level is high (for keypad GPIOs).
Thus, another new bit is introduced to indicate that the GPIO will
wakeup the system:
- MFP_LPM_WAKEUP_ENABLE
The following macros can be used in platform code, and be OR'ed to
the GPIO configuration to enable its wakeup:
- WAKEUP_ON_EDGE_{RISE, FALL, BOTH}
- WAKEUP_ON_LEVEL_HIGH
The WAKEUP_ON_LEVEL_HIGH is used for keypad GPIOs _only_, there is
no edge settings for those GPIOs.
These WAKEUP_ON_* flags OR'ed on wrong GPIOs will be ignored in case
that platform code author is careless enough.
The tradeoff here is that the wakeup source is fully determined by
the platform configuration, instead of enable_irq_wake().

The main issue here is that pxa3xx does not have GAFRx registers,
access directly to these registers should be avoided for pxa3xx:
1. introduce __gpio_is_occupied() to indicate the GAFRx and GPDRx
registers are already configured on pxa{25x,27x} while returns
0 always on pxa3xx
2. pxa_gpio_mode(gpio | GPIO_IN) is replaced directly with assign-
ment of GPDRx, the side effect of this change is that the pin
_must_ be configured before use, pxa_gpio_irq_type() will not
change the pin to GPIO, as this restriction is sane, esp. with
the new MFP framework

This makes the code better organized and simplified a bit. The change
will lose a bit of performance when performing IRQ ack/mask/unmask,but
that's not too much after checking the result binary.
This patch also removes the ugly #ifdef CONFIG_PXA27x .. #endif by
carefully not to access those pxa{27x,3xx} specific registers, this
is done by keeping an internal IRQ number variable. The pxa-regs.h
is also modified so registers for IRQ > PXA_IRQ(31) are made public
even if CONFIG_PXA{27x,3xx} isn't defined (for pxa25x's sake)
The incorrect assumption in the original code that internal irq starts
from 0 is also corrected by comparing with PXA_IRQ(0).
"struct sys_device" for the IRQ are reduced into one single device on
pxa{27x,3xx}.

The upcoming PB11MPCore and PB1176 have different memory maps and some
of the definitions in platform.h are no longer common. This patch
moves them to the board-eb.h file and updates their usage in
realview_eb.c.

Since the PB1176 has different UART base addresses, this patch moves
the definitions form platorm.h to board-eb.h. It also modifies
uncompress.h to detect the platform type at run-time.

This patch moves the timer definitions from platform.h into board-eb.h
as they are different on PB11MPCore and PB1176. It also adds
timerX_va_base variables in core.c which are set by the
realview_eb_timer_init function before invoking realview_timer_init.

This patch moves the patch definitions into board-eb.h and
realview_eb.c (from core.c) as they are different on the PB11MPCore
and PB1176 platforms.

This is in preparation for the RealView PB11MPCore and PB1176 patches
which have different base addresses for the GIC.

RealView/EB revD platform comes with the SMSC LAN9118 Ethernet
chip. This patch allows either the smc91x or the smc911x drivers to be
used with the RealView/EB platform.

This patch moves the SCU initialisation from __v6_setup to the
smp_prepare_cpus() function as it relies on platform-specific
settings. Changes to get_core_count() are mainly for allowing cleaner
code with the upcoming PB11MPCore patches.
