This adds initial board support for the BT Homehub V1/V1.5 for use with Redboot.
Looks like USB, Wireless, first ethernet port (not second for the
moment) all work. This is similar to the livebox implementation.
Detail: Adds
target/linux/brcm63xx/patches-2.6.35/340-add_bt_homehub_v1_v1.5.patch,
which in turn does:
Modifies /arch/mips/bcm63xx/boards/Kconfig to add the ability to
select the "BT Homehub V1/V1.5 Redboot" board
Modifies /drivers/mtd/maps/bcm963xx-flash.c to make the flash mapping
work when CONFIG_BOARD_BTHOMEHUBV1 is selected.
Adds /arch/mips/bcm63xx/boards/board_bthomehubv1.c, based on
board_livebox.c, but updated for some features of board_bcm63xx.c (I
think livebox may be broken with 2.6.35; the registration of serial
has changed in the kernel).
Modifies /arch/mips/bcm63xx/boards/Makefile to add the new c file when
CONFIG_BOARD_BTHOMEHUBV1 is selected.
