This patch implements the following:
- interrupt initialization uses ioremap() instead of passing a virtual address
via davinci_soc_info.
- machine definitions directly point to cp_intc_init() or davinci_irq_init()
- davinci_intc_type and davinci_intc_base now get initialized in controller
specific init functions instead of davinci_common_init()
- minor fix in davinci_irq_init() to use intc_irq_num instead of
DAVINCI_N_AINTC_IRQ

The board file #define's its own version of EMIFA base addresses, while there
are DA8XX_AEMIF_*_BASE macros #define'd in <mach/da8xx.h>. Start using them
instead.

Host map configuration instructs the interrupt controller to route interrupt
channels to FIQ or IRQ lines. Currently, DA8xx family of devices leave these
registers at their reset-default values.
TNETV107X however does not have sane reset defaults, and therefore this
architecture needs to reconfigure the host-map such that channels 0 and 1
go to FIQ, and the remaining channels raise IRQs.
This patch adds an optional host map argument to cp_intc_init() for this.

The merge for 2.6.34 brings in 8-bit support to the DaVinci MMC/SD driver.

The DA830/OMAP-L137 EVM has GPIO based card detection logic, but the current
code does not use it.
Add support for GPIO based card detection to avoid reading the card to see
if a card is present or not.

OMAP-L138 adds a second SYSCFG region having useful functionality
like deep sleep, pull up/down control and SATA clock stop.
This patch makes provision for accessing registers from second
SYSCFG region in da8xx code.
Note that OMAP-L137 has a single SYSCFG region.

When kernel is built with CONFIG_DEBUG_SECTION_MISMATCH=y
option, using da8xx_omapl_defconfig, some warnings are
observed:
WARNING: vmlinux.o(.text+0xc2a4): Section mismatch in reference
from the function da850_evm_setup_nor_nand() to the variable
.init.data:da850_nand_pins
The function da850_evm_setup_nor_nand() references
the variable __initdata da850_nand_pins.
This is often because da850_evm_setup_nor_nand lacks a __initdata
annotation or the annotation of da850_nand_pins is wrong.
This patch fixes such warnings.

On the DA830, AEMIF and MMC/SD pins are shared. On the EVM, when
the mux_mode signal is low MMC/SD works and when mux_mode signal
is high, NAND works.
When MMC/SD driver is configured in the kernel, do not let NAND
get registered and drive mux_mode high. Instead, print a warning
for user to understand why the platform device for NAND did not
get registered.

This patch supports runtime detection of DA830 UI card and
eliminates the need for DA830_UI config option. Successful
probe of GPIO expander present on the UI card is used to
detect its presence. For this reason, GPIO_PCF857X is auto-
selected when DA830 EVM is configured. In case the UI card
is absent, the probe fails in reasonable time.
As a side effect this patch also gets rid of the voilation
of Documentation/SubmittingPatches section 2.2 in function
da830_evm_ui_expander_setup()

On this board the OHCI port's power control and over-current signals from
TPS2065 power switch are connected via GPIO1[15] and GPIO2[1] respectively,
so we can implement the DA8xx OHCI glue layer's hooks for overriding the
root hub port's power and over-current status bits.
We also have to properly set up the clocking mode in the CFGCHIP2 register,
so that internal 24 MHz reference clock is fed to the USB 2.0 (MUSB) PHY and
its output is used to clock the USB 1.1 (OHCI) PHY...

Add graphics support for the Sharp LCD035Q3DG01 graphical
LCD that's on the User Interface (UI) daughter card of the
DA830/OMAP-L137 EVM.
The LCD shares EMIFA lines with the NAND and NOR devices that
are also on the UI card so those lines are shared via a couple
of muxes. The muxes are controlled by the 'MUX_MODE' line on
the UI card. The 'MUX_MODE' line is controlled by pin P6 of
a pcf8574 i2c expander that's at i2c address 0x3f on UI card.
The i2c expander is controlled using the gpio infrastructure
from the board code using the 'setup()' and 'teardown()'
routines.
