For best performance, codecs often setup linked triggered
transfers with a contiguous block of params, and that is when
this API is used. Setup/configuration of these parameter RAMs
is most efficient if they are contiguous.
There is an API to allocate a set of contiguous parameter RAMs and
a corresponding API to free a set of contiguous parameter RAMs

This patch adds definitions for some DM365 IRQs that are used by
the codecs. Codecs will also use the IRQs.
Entries are being added to enable/disable IRQ's.
There is no use as such for these entires in the kernel itself.
Instead these will be used by the "linuxutils" package of the DVSDK.

Earlier patch which adds EMAC support for da850/omap-l138
was not configuring the MDIO pins.

Ethernet was working fine with the earlier patch, because
the MDIO pins were configured from the boot loader. This
patch removes that dependency.

Also, this patch populates a member in the emac clk structure
to say that EMAC LPSC sits on controller 1.

EDMA queues in DM365 are a little different than those
on other DaVinci's. On DM365 Q0 and Q1 have the larger
FIFO size. We want Q0 and Q1 to be used by codecs and
DVSDK demos.
MMC driver is the only driver which uses the flag
'EVENTQ_DEFAULT'. So MMC driver should be using Q2 instead of
Q1 on DM365.
This patch allows us to declare a "default queue" from
SOC specific code. If it is not declared then the EDMA
driver assumes a default of queue 1.

Add support for the DA850/OMAP-L138 Evaluation Module (EVM)
from TI.  The EVM has User Interface (UI) card which contains
various devices. This UI card can be connected to the base
board. Support for all the devices on the UI card and ones on
the EVM will be added in subsequent patches.

The EVM schematics are not available publicly yet; but should
be available soon.

A new defconfig for this board has been added mainly because
the DA830/OMAP-L137 defconfig forces writethrough cache mode
which is not required on DA850/OMAP-L138.

This patch adds platform data and init function for IDE which could be called
from board specific file to register IDE device.

Note that for 594MHz device the transfer mode is limited to UDMA4 since ideclk
rate is less than 100 MHz, which forces udma_mask in palm_bk3710.c to UDMA4,
while for 729MHz device, it is UDMA5.

This patch takes out IO mapping macros from mach/io.h and puts them in
mach/hardware.h avoiding need to include mach/io.h in various files such as
serial.h, vmalloc.h etc.

The main reason to avoid inclusion of mach/io.h is, when default in/out macros
are overridden by machine specific functions (e.g., in case of PCI I/O), they
result into linker error. An example snippet and error snapshot is listed below.

Following code in mach/io.h:

	#define inl(p)  my_inl()

	static inline unsigned int my_inl(unsigned int addr)
	{
		if (IS_PCI_IO(addr))
			return pci_inl ();
		else
			return le32_to_cpu(__raw_readl(__typesafe_io(addr)));
	}

leads to error:
	LD      arch/arm/boot/compressed/vmlinux
	arch/arm/boot/compressed/misc.o: In function `my_inl':
	misc.c:(.text+0x2744): undefined reference to `pci_inl'
	make[2]: *** [arch/arm/boot/compressed/vmlinux] Error 1

This is because mach/io.h gets included in arch/arm/boot/compressed/misc.c
through mach/serial.h but pci.c file, which defines 'pci_inl' doesn't get built
into compressed vmlinux.

Support DM365 GPIOs ... primarily by handling non-banked GPIO IRQs:

 - Flag DM365 chips as using non-banked GPIO interrupts, using a
   new soc_info field.

 - Replace the gpio_to_irq() mapping logic.  This now uses some
   runtime infrastructure, keyed off that new soc_info field,
   which doesn't handle irq_to_gpio().

 - Provide a new irq_chip ... GPIO IRQs handled directly by AINTC
   still need edge triggering managed by the GPIO controller.

DM365 chips no longer falsely report 104 GPIO IRQs as they boot.

Intelligence about IRQ muxing is missing, so for the moment this
only exposes the first eight DM365 GPIOs, which are never muxed.
The next eight are muxed, half with Ethernet (which uses most of
those pins anyway).

Tested on DM355 (10 unbanked IRQs _or_ 104 banked ones) and also
on DM365 (16 unbanked ones, only 8 made available).
