[U-Boot] [PATCH v5 08/23] Define CONFIG_SYS_LEGACY_BOARD everywhere

Fri Feb 8 16:12:04 CET 2013
We are introducing a new unified board setup and we want this to
be the default. So we need to opt all architectures out first.

+- 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 NOT define CONFIG_SYS_LEGACY_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:
