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

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:

OMAP3630 is the latest in the family of OMAP3 devices
and among the changes it introduces are:

New OPP levels for new voltage and frequency levels. a bunch of
Bug fixes to various modules feature additions, notably with ISP,
sDMA etc.

Details about the chip is available here:
http://focus.ti.com/general/docs/wtbu/wtbuproductcontent.tsp?templateId=6123&navigationId=12836&contentId=52606

Strategy used:
Strategy to introduce this device into Linux was discussed here:
Ref: http://marc.info/?t=125343303400003&r=1&w=2

Two approaches were available:
a) Consider 3630 generation of devices as a new family of silicon
b) Consider 3630 as an offshoot of 3430 family of devices

As a common consensus, (b) seems to be more valid for 3630 as:
* There are changes which are easily handled by using "FEATURES"
  infrastructure.
  For details how to do this, see thread:
  http://marc.info/?t=125050998500001&r=1&w=2
* Most of existing 34xx infrastructure can be reused(almost 90%+)
	- so no ugly if (cpu_is_omap34xx() || cpu_is_omap36xx())
	  all over the place
	- lesser chance of bugs due to reuse of proven code flow
	- 36xx specific handling can still be done where required
	  within the existing infrastructure

NOTE:
* If additional 34xx series are added, OMAP3430_REV_ESXXXX can be
  added on top of the existing 3630 ones are renumbered

Note that mach-omap1 uses struct plat_serial8250_port
array, which requires a null terminator at the end,
and that's why we need to use ARRAY_SIZE - 1. This
is not needed on mach-omap2 as the array used is
