__HAVE_ARCH_GENERIC_BOARD controls availabilty of generic board
We are introducing a new unified board setup. Add a check to make sure that board config files do not define CONFIG_SYS_GENERIC_BOARD unless their architecture defines __HAVE_ARCH_GENERIC_BOARD __HAVE_ARCH_GENERIC_BOARD will currently not be the default setting, but we can switch this later when most architecture support generic board.

+- CONFIG_SYS_GENERIC_BOARD
+ This selects the architecture-generic board system instead of the
+ architecture-specific board files. It is intended to move boards
+ to this new framework over time. Defining this will disable the
+ arch/foo/lib/board.c file and use common/board_f.c and
+ common/board_r.c instead. To use this option your architecture
+ must support it (i.e. must define __HAVE_ARCH_GENERIC_BOARD in
+ its config.mk file). If you find problems enabling this option on
+ your board please report the problem and send patches!

The following definitions that deal with the placement and management
of environment data (variable area); in general, we support the
following configurations:
