MIPS: generic: Support MIPS Boston development boards
Add support for the MIPS Boston development board to generic kernels, which essentially amounts to: - Adding the device tree source for the MIPS Boston board. - Adding a Kconfig fragment which enables the appropriate drivers for the MIPS Boston board. With these changes in place generic kernels will support the board by default, and kernels with only the drivers needed for Boston enabled can be configured by setting BOARDS=boston during configuration. For example: $ make ARCH=mips 64r6el_defconfig BOARDS=boston Signed-off-by: Paul Burton <paul.burton@imgtec.com> Reviewed-by: James Hogan <james.hogan@imgtec.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/16485/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
