Before adding -support for bcma it should be possible to build bcm47xx without the -need of ssb. With this patch bcm47xx does not directly contain a -ssb_bus, but a union contain all the supported system buses. As a SoC -just uses one system bus a union is a good choice. - -Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> ---- - arch/mips/bcm47xx/gpio.c | 56 ++++++++++++++++---------- - arch/mips/bcm47xx/nvram.c | 15 +++++-- - arch/mips/bcm47xx/serial.c | 13 +++++- - arch/mips/bcm47xx/setup.c | 33 ++++++++++++--- - arch/mips/bcm47xx/time.c | 9 +++- - arch/mips/bcm47xx/wgt634u.c | 14 ++++-- - arch/mips/include/asm/mach-bcm47xx/bcm47xx.h | 14 ++++++- - arch/mips/include/asm/mach-bcm47xx/gpio.h | 55 ++++++++++++++++++------- - drivers/watchdog/bcm47xx_wdt.c | 12 +++++- - 9 files changed, 160 insertions(+), 61 deletions(-) - ---- a/arch/mips/bcm47xx/gpio.c -+++ b/arch/mips/bcm47xx/gpio.c -@@ -20,42 +20,54 @@ static DECLARE_BITMAP(gpio_in_use, BCM47 - - int gpio_request(unsigned gpio, const char *tag) - { -- if (ssb_chipco_available(&ssb_bcm47xx.chipco) && -- ((unsigned)gpio >= BCM47XX_CHIPCO_GPIO_LINES)) -- return -EINVAL;
