3630 is getting treated like next rev of 3430
omap_chip.oc variable has to be updated for 3630 version
Otherwise the Core power domain is not getting registered.
This gets used in the registration of power domains in:
"arch/arm/mach-omap2/powerdomains34xx.h"
core_34xx_es3_1_pwrdm
OMAP_CHIP_INIT(CHIP_GE_OMAP3430ES3_1)
Core power doman will get registered for 3630 only when .oc is
populated correctly.
Tested on Zoom3(3630) board

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
This patch was tested on SDP3430, boot tested on 3630 platform using
3430sdp defconfig

The OMAP35x family has multiple variants differing
in the HW features. This patch detects these features
at runtime and prints information during the boot.
Since most of the code seemed repetitive, macros
have been used for readability.

The MMC mux pins normally used by omap chips in devices.c
are different from what is needed by omap7xx chips. This
change adds a conditional around the mux setup code to
enable the correct mux pins.
The omap730 and omap850 both use a different clock for the "fck"
clock of the MMC interface than other omap processors based on the
SOFT_REQ_REG, pin 12. The "ick" clock is the same as that used
by other omap processors.
* Added the missing clock definition as mmc3_ck to clock.h
* Added the clock definition to omap_clks in clock.c
* Added CK_7XX to the mmci-omap.0 "ick" clock already in clock.c
With these changes, it is now possible to initialize and use MMC
cards with omap730 and omap850 devices.

Zoom2/Zoom3 kind of boards do not use omap uarts for console.
These use external debug board for console.
So these boards should not have "Uncompressing Kernel...."
log put on omap uarts.
By interoducing OMAP_LL_DEBUG_NONE option,
unnecessary writes to omap uarts is avoided.
In future, the DEBUG_LL interface will be enhanced
to use external debug board.

Eliminate OMAP_MAX_NR_PORTS
Note that also the null terminator entry for omap1
serial_platform_data needs to be now removed to avoid
oopsing.
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
struct omap_uart_state, and does not use a null
terminator.

Due to an OMAP3 errata (1.142), on HS/EMU devices SDRC should be
programed to issue automatic self refresh on timeout
of AUTO_CNT = 1 prior to any transition to OFF mode.
This is needed only on sil rev's ES3.0 and above.
This patch enables the above needed WA in the SDRC power register
value stored in scratchpad, so that ROM code restores this value
in SDRC POWER on the wakeup path.
The original SDRC POWER register value is stored and restored back
in omap_sram_idle() function.
This fixes some random crashes observed while stressing suspend
on HS/EMU devices.
