We don't have cpu_is_omapxxxx SoC detection initialized until
SoC detection is initialized from init_early.
Note that with the common map_io we should no longer need
cpu_is_omapxxxx for ioremap.

Otherwise multi-omap1 support for omap1 won't work as the cpu_class_is_omap1()
won't work until the SoC is detected.
Note that eventually these will go away, please use ioremap + read/write instead.

This patch removes the L4 wakeup io mapping section for omap3
and omap4. L4 wakeup space is part of 4MB L4 space which is
already mapped and hence remove the overlapped mapping.

This allows the procfs vmallocinfo file to show who created the ioremap
regions. Note: __builtin_return_address(0) doesn't do what's expected
if its used in an inline function, so we leave __arm_ioremap callers
in such places alone.

Out of the three major OMAP2 chip types, OMAP2420, OMAP2430, and OMAP3430,
we only map the IVA on OMAP2420. The memory mapping is not shared between
OMAP2420 and OMAP2430, so it is inappropriate to label those macros as
'24XX'; this patch changes them to '2420'.

Move the remaining headers under plat-omap/include/mach
to plat-omap/include/plat. Also search and replace the
files using these headers to include using the right path.
This was done with:
#!/bin/bash

plat_dir_new="arch/arm/plat-omap/include/plat"
headers=$(cd $mach_dir_old && ls *.h)

This patch splits OMAP2_IO_ADDRESS to OMAP2_L3_IO_ADDRESS and
OMAP2_L4_IO_ADDRESS to reclaim more IO space.
The omap_read*() and omap_write*() functions will work only over
L4 address space. Current omap kernel stack uses these functions
only to access registers over L4 io address space
Note that these macros should only be used when ioremap does
not work. Please use ioremap instead in all new code.

This patch is part of a series which unifies all duplicated code between

Search and replace OMAP_IO_ADDRESS with OMAP1_IO_ADDRESS and OMAP2_IO_ADDRESS,
and convert omap_read/write into a functions instead of a macros.
Also rename OMAP_MPUIO_VBASE to OMAP1_MPUIO_VBASE.
In the long run, most code should use ioremap + __raw_read/write instead.

This patch adds the support for OMAP4. The platform and machine specific
headers and sources updated for OMAP4430 SDP platform.
OMAP4430 is Texas Instrument's SOC based on ARM Cortex-A9 SMP architecture.
It's a dual core SOC with GIC used for interrupt handling and SCU for cache
coherency.

Add minimal omap3430 support based on earlier patches from
Syed Mohammed Khasim. Also merge in omap34xx SRAM support
from Karthik Dasu and use consistent naming for sram init
functions.
Also do following changes that make 34xx support usable:
- Remove unused sram.c functions for 34xx
- Rename IRQ_SIR_IRQ to INTCPS_SIR_IRQ and define it locally
in entry-macro.S
- Update mach-omap2/io.c to support 2420, 2430, and 34xx
- Also merge in 34xx GPMC changes to add fields wr_access and
wr_data_mux_bus from Adrian Hunter
- Remove memory initialization call omap2_init_memory() until
until more generic memory initialization patches are posted.
It's OK to rely on bootloader initialization until then.
