Zoom3 is the next version of Zoom2 board.
There has been a silicon update from zoom2 to zoom3.
        Zoom2 has OMAP34xx
        Zoom3 has OMAP3630 [1]
Zoom3 = OMAP3630 SOM board [2] + same zoom2 main board [3] + same debugboard

Zoom3 has a SDRAM part from Hynix
Zoom2 had SDRAM part from micron

Hynix memory timings are contributed by:
Chalhoub, Nicole and Bour, Vincent

Reuse the zoom2 files as much for zoom3, as at board level,
there is no change at all.

The I2C-1 bus frequency on zoom2/zoom3/sdp3630 should be 2.4 MHz.
The speed is limited by TWL5030/GAIA; a higher speed could lead to errors
on the interface.

The maximum I2C speed depends on the system clock for GAIA:
2.2 MHz (sys-clk = 19.2 MHz)
2.4 MHz (sys-clk = 26 MHz)
2.9 MHz (sys-clk = 38.4 MHz)

For Zoom2/Zoom3/SDP3630 the system clock is 26Mhz
and hence choose 2.4Mhz for I2C1 bus speed

Replace zoom2 with zoom name in board-zoom-peripherals.c file

Hence have all functions commonly named as zoom

Split zoom2 board file into a base board file and a board-zoom-peripherals.c
file. That way the same peripherals file can be reused for zoom3 and sdp3630
in addition to zoom2.

Also remove unused struct omap_board_config_kernel entry.

NOTE: Keep the twl4030_madc_platform_data and twl4030_platform_data
entries in board-zoom2.c to avoid merge conflicts with the pending
patches in MFD tree. These entries will be removed later as a fix.

Following list shows the commonality across the three platforms and hence the
case for software reuse:

Migrate to smsc911x ethernet driver instead of smc911x driver.
The smsc911x ethernet driver supports NAPI and performs better
under heavy traffic. With the smc911x driver we were witnessing
very high iowait time for high IO load over NFS.

Added runtime programming for the differences in EHCI interface between
OMAP3EVM revisions (Rev >= E) and (Rev < E).

Changes:
	- EHCI PHY reset GPIO pin is 21 on Rev >= E while Rev < E
	  uses GPIO pin 135.
	- Rev >= E uses EHCI Vbus enable GPIO22 line.
	- Rev >= E uses GPIO61 to select EHCI port either on main board or
	  on Mistral Daughter Card (MDC). OMAP3EVM Rev < E doesn't have
	  EHCI port on main board.
	- Currently GPIO61 it programmed to enable EHCI port on main
	  board only.

The mainline merge of the 3430SDP support (commit 6fdc29e2)
seems to have messed up the 3430 defconfig completely.

Update the defconfig using a known good version
(SDP defconfig from v2.6.26-omap2 and current beagle defconfig)
as reference.

The image size is now 1.9 MB down from 2.4 MB earlier, and
the number of modules is 8, down from 203. Build time also
scales proportionally.

Other support (OneNAND, etc) can be enabled as needed.

Note that this patch intentionally does not update CONFIG_FB
related options to avoid merge conflicts with the pending
omap_dss2 patches.

This patch disables a GPIO module when all pins of a GPIO
module are inactive (clock gating forced at module level) and
enables the module when any gpio in the module is requested.

The module is enabled only when "mod_usage" indicates that no GPIO
in that  module is currently active and the GPIO being requested
is the 1st one to be active in that module.

Each module would be disabled in omap_gpio_free() API when all
GPIOs in a particular module becomes inactive. The module is
re-enabled in omap_gpio_request() API when a GPIO is requested
from the module that was previously disabled.

Since individual GPIO's bookkeeping is added in this patch
via "mod_usage", the same is used in omap_set_gpio_debounce()
& omap_set_gpio_debounce_time() APIs to ensure that the gpio being
used is actually "requested" prior to being used (Nishant Menon's
<nm@ti.comSuggestion)

GPIO module level details are specific to hardware and hence
introducing this patch in low level layer (plat-omap/gpio.c)

the initialization of da should be moved below the test.

All of the OMAP3 IVA physical address macros in
plat-omap/include/plat/omap34xx.h are wrong[1]:

OMAP34XX_IVA_INTC_BASE: The IVA interrupt controller does not appear
to be accessible from the L3 interconnect, and in any case is
definitely not at 0x40000000; the latter address appears to be the
internal IVA physical address base for the OMAP2420's interrupt control[2].

OMAP34XX_DSP_BASE: The section of L3 physical address space mapped to
the IVA starts at 0x5c000000, not 0x58000000.

OMAP34XX_DSP_MEM_BASE: It's not clear what this refers to, but it's not
in the L3 IVA address space.

OMAP34XX_DSP_IPI_BASE: The Intrusive Port Interface is a relic from
the OMAP2420 days and no longer applies to OMAP3.

OMAP34XX_DSP_MMU_BASE: The DSP MMU is mapped at 0x5d000000, not 0x5a000000.


Nothing that uses these can possibly be working, so drop them.  When
future code needs these, correct versions can be added in.
