[PATCH 2/3] MIPS: Add generic list_* Makefile targets

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add MIPS specific Makefile targets for listing generic defconfigs
(list_generic_defconfigs), generic board types (list_generic_boards),
and legacy defconfigs which have been converted to generic
(list_legacy_defconfigs).

This is useful for quick reference and for buildbots to be able to
automatically build all supported default configurations without parsing
of the generic_defconfig error output.

In order for these to work without .config being updated or
CROSS_COMPILE being needed, list_%s is added to no-dot-config-targets in
the main Makefile.
