b8cf7cc886 arm/km: add implementation for read_dip_switch
Add a function to read the dip_switch on kmcoge5un. If the
switch is set the actual_bank is set to 0 and this SW is
booted.

48ced62cfb arm/km: cleanup km_kirkwood boards
Remove config options from boards.cfg and simply add one switch
per board and differ afterwards in km_kirkwood.h between the features.
More boards are upcoming and therefore it's easier to have this
at one place.

b37f772433 arm/km: enable BOCO2 FPGA download support
This adds a first support of the FPGA download for a PCIe FPGA based
on the BOCO2 CPLD.

This takes place in 3 steps, all done accessing the SPICTRL reg of the
BOCO2:
1) start the FPGA config with an access to the FPGA_PROG bit
2) later in the boot sequence, wait for the FPGA_DONE bit to toggle to 1
   for the end of the FPGA configuration (with a timeout)
3) reset the FPGA
4) finally remove the access to its config EEPROM from the FPGA so that
   the CPU can update the FPGA configuration when the kernel is running

The boards with a PCIe FPGA but without BOCO2 still are supported.

The config option name is CONFIG_KM_FPGA_CONFIG

6ef6486180 arm/km: remove portl2.h and use km_kirkwood instead
The additional headerfile is unneeded here, we can use the generic
km_kirkwood.h instead. And we can use the better config option
KM_PIGGY4_88E6061 for the specific features for boards with this
design in km_arm.c.

d9354530fe arm/km: add kmcoge5un board support
For u-boot this board is similar to mgcoge3un. But some differences
are present. We have a different SDRAM on it and therefore a new
SDRAM config file. Additionaly this board has a direct MAC/MAC
connection from the kirkwood to a marvell simple switch without a
phy inbetween, this needs a new configuration for the mvgbe driver.

8170aefc84 arm/km: add kmnusa board support
This board is similar to portl2, but it has the u-boot environment
in a SPI NOR flash and not in an i2c eeprom like portl2 have.

Some other details:
 - IVM EEPROM is at adress: pca9547:70:9
 - PCI is enabled
 - PIGGY4 is connected via MV88E6352 simple switch. There is no phy
   between the simple switch and the kirkwood.

f3f98bb0b8 ARM: OMAP4/5: Do not configure non essential pads, clocks, dplls.
Currently on OMAP4/5 platforms, many kernel drivers are dependent
upon the bootloaders for mux, dpll and clock configurations.
This should not be the case and bootloaders should set only the
minimum required for the uboot functionality and kernel boot.

Note that this is going to break the kernel drivers. But this
is the only way to get things fixed in the kernel.

0c25defccd arm/km: use spi claim bus to switch between SPI and NAND
We overwrite these weak functions from the kirkwood spi code to
use our own method to be able to switch between the SPI NOR and
the NAND flash. This is needed e.g. to update the u-boot. The former
command do_spi_toggle can therefore be removed. And the usage of
this command is removed from the u-boot update command in the
u-boot environment.

e139cb31d3 AT91SAM9*: Change kernel address in dataflash to match u-boot's size
On at91sam platforms, u-boot grew larger than the allocated size in

uboot      0x00008400
kernel     0x00042000
fs         0x00252000

u-boot with the defconfig doesn't seem to fit in 0x42000 - 0x8400 =
0x39C00 bytes anymore.

Now, the layout is:
bootstrap  0x00000000
ubootenv   0x00004200
uboot      0x00008400

Built all Tegra builds OK; Booted on Seaboard and saw
ODMDATA in PMC scratch20 was the same as the value in my
burn-u-boot.sh file (0x300D8011). NOTE: All flash utilities
will have to specify the odmdata (nvflash --odmdata n) on
the command line or via a cfg file, or built in to their
BCT.

f9f2f12e2c tegra: seaboard: disable SPI, move environment to eMMC
The SPI hardware on Seaboard is too broken to use; it is muxed with the
console UART and requires evil interactions between the SPI and UART
drivers to work even partially. The current code in U-Boot is not
sufficient to make this work correctly; auto boot is aborted due to
corruption in the UART RX channel interrupting it.

Instead, move the environment to eMMC, at the end of the second boot
sector. This should not conflict with any other eMMC usage, irrespective
of whether the board boots from SPI, NAND, or eMMC: if U-Boot is stored
in eMMC, it will be stored well below this location. The kernel only
uses the general area of the eMMC once booted, not the boot sectors.

Boards that are derivatives of Seaboard don't have the muxing issue,
and should/could have a separate U-Boot configuration file that does
enable SPI if desired.

Alternatively, the environment could be stored in NAND flash, but we
currently have no driver for that controller.
