I'm not sure I understand the question (or rather the problem you are
seeing).

You already know the board name, because the board config file is
clearly related ot one (or eventually more) boards. The rest can be
done with some trivial #ifdef'fery.

You can for example set CONFIG_SYS_MONITOR_BASE (or some other CONFIG_
variable - but CONFIG_SYS_MONITOR_BASE is used anyway) as needed in your
include/configs/*.h, which then gets exported through
include/autoconf.mk, so you can use some
"TEXT_BASE = $(CONFIG_SYS_MONITOR_BASE)" in your config.mk

Best regards,
