Sun May 15 02:49:27 CEST 2016
Remove the warning from the Makefile, since boards that do not use generic
board will no longer build. Also update documentation.

-Supported Architectures
-------------------------
-
-If you are unlucky then your architecture may not support generic board.
-The following architectures are supported now:
-
- arc
- arm
- avr32
- blackfin
- m68k
- microblaze
- mips
- nios2
- powerpc
- sandbox
- x86
-
-If your architecture is not supported, you need to select
-HAVE_GENERIC_BOARD in arch/Kconfig
-and test it with a suitable board, as follows.

-
-Adding Support for your Board
------------------------------
-
-To enable generic board for your board, define CONFIG_SYS_GENERIC_BOARD in
-your board config header file.
-
-Test that U-Boot still functions correctly on your board, and fix any
-problems you find. Don't be surprised if there are no problems - generic
-board has had a reasonable amount of testing with common boards.

---------

-Please don't take this the wrong way - there is no intent to make your life

-However, with any migration there has to be a period where the old way is

-Boards or architectures not converted over to general board by the
