6cbec7b3ba ARMV7: OMAP3: Cleanup extern variables in mem.c
Removed boot_flash_* extern variables.
boot_flash_type was totally unused. The other ones were actually constants, so
they have been replaced with #defines in the board config files.

8b6724aa5a OMAP3: remove unused config macros
Most OMAP3 boards have various flash related macros in their configs
that are either not referenced anywhere in the code or are used by
drivers that are not enabled. Remove them.

25ddd1fb0a Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value
CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough.  This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool.  In the result, all definitions of this value can be
deleted from the board config files.  We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.

No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.

f56348af5d ARM: Rename arch/arm/cpu/arm_cortexa8 to armv7
The purpose of this patch is to prepare for adding the OMAP4 architecture, which is Cortex A9

Cortex A8 and A9 both belong to the armv7 architecture, hence the name change.

The two architectures are similar enough that substantial code can be shared.

function (mem_init), this generalization of omap memory setup

2ec1abea43 OMAP3 zoom2 Use usbtty if the debug board is not connected.
The preferred serial output comes from the debug board.
When the debug board is disconnected, fall back on using
usbtty from the usb connector on the Zoom2 board.

This shows up as /dev/ttyACM0 in a linux host.

0297ec7e2a TI OMAP3 Use arm init sequence to initialize i2c
This changes fixes an early i2c error.

It appears that I2C is working because once a read or write
error is detected, the omap24xx_i2c driver calls i2c_init
inside its error handling check.

While it is ok to attempt error handling this way, the boards
must not depend on this side effect to initialize it's i2c.

Instead of explicitly calling i2c_init for every board, use
the generic arm initialization in lib_arm/board.c. By defining
the config variable CONFIG_HARD_I2C, the omap3 i2c initialization
is included in the init_sequence table.

Run tested on Beagle.
Compile tested on the omap3's

2c15513010 OMAP3 Move twl4030 power and led functions
Because twl4030 now has its own device files, move exiting
omap3 power_init_r to a new location.

power_init_r is the only function in board/omap3/common.
It initializes the twl4030 power for the board and enables
the led.

The power part of the the function is moved to twl4030_power_init in
drivers/power/twl4030.c The power compilation is conditional on the
existing config variable CONFIG_TWL4030_POWER.

The led part is moved to twl4030_led_init in the new file
drivers/misc/twl4030_led.c  The led compilation is conditional on
the new config variable CONFIG_TWL4030_LED

The directory board/omap3/common was removed because power_init_r
was the only function in it.

cd7826359e TWL4030 Add power reset button
The Zoom2 power reset button is on the top right side of the
main board.  Press and hold for about to 8 seconds to completely
reset the board.

Some of the beta boards have a hardware problem that prevents
using this feature.  If is difficult to further characterize the
boards that fail.  So disable resetting for all beta boards.

The Zoom1 reset button is the red circle on the top right,
front of the board.  Press and hold the button for 8 seconds to
completely reset the board.

After analyzing beagle, it was determined that other boards
that use the twl4030 for power managment can also make use
this function.

The resetting is done by the power management part of the twl4030.
Since there is no existing drivers/power, add one.

The compilation of power/twl4030.h is controlled by the config
variable CONFIG_TWL4030_POWER

660888b7fb ZOOM2 Add serial support.
Zoom2 serial is in general supplied by one of the 4 UARTS on the debug board.
The default serial is from the USB connector on left side of the debug board.
The USB connector will produce 2 of the 4 UARTS.  On your host pick the first
enumeration.

The details of the setting of the serial gpmc setup are not available.
The values were provided by another party.

The serial port set up is the same with Zoom1.
Baud rate 115200, 8 bit data, no parity, 1 stop bit, no flow.
