[netx] compile fixes, update netx defconfig

[memory layout]: streamline memory layout ...

Memory layout can now be specified via kconfig options. Two
possibilities exist: default layout means the layout is stack
/ malloc heap / U-Boot. The user can also specify fixed addresses
for each TEXT_BASE / stack / malloc heap.

[general] Move include/configs/* to board/*/config.h

[ARM] Remove CONFIG_ARCH_NUMBER from Kconfig system. Putting too many ...

values into kconfig which are not user configurable at all only
      encourages people to put even more stuff in there. This is not
      good because people tend to have board patches lying around and
      these patches won't apply regularly if they all change the same
      file (arch/arm/Kconfig)
      Instead, introduce a function armlinux_set_architecture() which
      everyone can call during board setup.
      Similarly introduce armlinux_set_bootparams() for the boot
      parameter pointer.

netx doc added and some typos fixed

- Implement tree structure for devices ...

- Use device tree structure to implement partitions
- Let devinfo print a nice tree
- Introduce 'fixed' partitions which are not removable
- Fix mount: It was not possible to mount on a relative path.

Linking: Remove linker scripts from (arm based-) boards and add ...

a generic linker script to arch/arm/lib/u-boot.lds.S.
	 If a board wants to overwrite a linker script it can do
	 so using CONFIG_BOARD_LINKER_SCRIPT.
	 There is no generic linker script for ppc and blackfin
	 yet, so still use the board specific one.

arm: use text_entry for reset vector instead of hardcoded filename ...

(once again)

changing function name for board specific init

whitespace cleanup

add hilscher netx support
