+- 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!
+
+- CONFIG_SYS_SYM_OFFSETS
+       This is set by architectures that use offsets for link symbols
+       instead of absolute values. So bss_start is obtained using an
+       offset _bss_start_ofs from CONFIG_SYS_TEXT_BASE, rather than
+       directly. You should not need to touch this setting.
