2b5b2be5e9 board/BuR/common: move I2C initialization from common part to board-specific
At this time I2C and responsible pin-mux is setup during PMIC initialziation
within common.c, this is possible because today PMIC is always connected on
I2C0.

In Future this will be changed, PMIC isn't anymore connected to bus0 in call
cases.

So we do following:
- rename enable_i2c_pin_mux0 to enable_i2c_pin_mux to be generic for enabling
  pin-mux on different or more busses.
- move the call to i2c_pin_mux and i2c_init from common.c to the specific
  board.c

8db622cdd4 board/BuR/kwb: Support modify bootcmd through reset-controller
For some cases it is necessary to modify temporaly the bootcommand.
This can be done by writing into the Scratchregister a specific value:

* 0xCC - modify bootcmd "run netboot"
* 0xCD - modify bootcmd "run netscript"
* 0xCE - modify bootcmd "run mmcboot"

the environment in flash is NOT overwritten.

a9642925a1 board/BuR/kwb: Form a bootline for vxWorks
vxWorks needs several parameters which are set by the bootloader und his
environment. So we form a vxWorks bootline and pass the result to vxWorks on
a predefined address.

cf630f289f board/BuR/kwb: switch to board HW-Rev3
The board has been redesigned, therefore we need from now other I/O Pins to
mux and handle.

Older boards aren't supported from now anymore.

2e07c249a6 kconfig: arm: introduce symbol for ARM CPUs
This commit introduces a Kconfig symbol for each ARM CPU:
CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136,
CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100.
Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected
for CPU_ARM1176 and CPU_V7.

For each target, the corresponding CPU is selected and the definition of
SYS_CPU in the corresponding Kconfig file is removed.

Also, it removes redundant "string" type in some Kconfig files.

207828e215 board/BuR: fix pinmux for MII Ethernet Interface
The lines COL (collision detect) and CRS (carrier sense) needs to be connected
and muxed to the CPSW MAC for a proper function in half-duplex Mode of the
interface.

461be2f96e kconfig: remove redundant "string" type in arch and board Kconfigs
Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME}
are specified in arch/Kconfig.

We can delete the ones in arch and board Kconfig files.

This commit can be easily reproduced by the following command:

find . -name Kconfig -a ! -path ./arch/Kconfig | xargs sed -i -e '
/config[[:space:]]SYS_\(ARCH\|CPU\|SOC\|\VENDOR\|BOARD\|CONFIG_NAME\)/ {
    N
    s/\n[[:space:]]*string//
}
'

93d4334f7f Add board MAINTAINERS files
We have switched to Kconfig and the boards.cfg file is going to
be removed. We have to retrieve the board status and maintainers
information from it.

The MAINTAINERS format as in Linux Kernel would be nice
because we can crib the scripts/get_maintainer.pl script.

After some discussion, we chose to put a MAINTAINERS file under each
board directory, not the top-level one because we want to collect
relevant information for a board into a single place.

TODO:
Modify get_maintainer.pl to scan multiple MAINTAINERS files.

dd84058d24 kconfig: add board Kconfig and defconfig files
This commit adds:
 - arch/${ARCH}/Kconfig
    provide a menu to select target boards
 - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
    set CONFIG macros to the appropriate values for each board
 - configs/${TARGET_BOARD}_defconfig
    default setting of each board

(This commit was automatically generated by a conversion script
based on boards.cfg)

In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.

But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.
