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.
Signed-off-by: Simon Glass sjg@chromium.org --- Changes in v8: - Switch polarity: !CONFIG_SYS_LEGACY_BOARD becomes __HAVE_ARCH_GENERIC_BOARD
Changes in v7: - Add description of CONFIG_SYS_LEGACY_BOARD to README

+- 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: diff --git a/config.mk b/config.mk index b7cd481..9886415 100644 --- a/config.mk +++ b/config.mk @@ -221,6 +221,14 @@ ifeq ($(CONFIG_SPL_BUILD),y) CPPFLAGS += -DCONFIG_SPL_BUILD endif
