The msp71xx_defconfig has never compiled in a kernel release. This is because the file msp_setup.c relies on some definitions from the PMCMSP GPIO driver, which has not yet been accepted into the kernel. This patch checks for the existence of the PMCMSP GPIO driver; if it doesn't exist, no GPIO functions are referenced. This patch will continue to work after the GPIO driver has been accepted, so no changes will be necessary when that happens.

I'm trying to wrangle some hardware to sort this out. Note that removing the definition of plat_timer_setup in msp_time.c allows the kernel to compile completely, but I don't know if it will run. diff -uprN orig/arch/mips/pmc-sierra/msp71xx/msp_setup.c patched/arch/mips/pmc-sierra/msp71xx/msp_setup.c --- orig/arch/mips/pmc-sierra/msp71xx/msp_setup.c 2008-08-17 10:15:11.000000000 -0600 +++ patched/arch/mips/pmc-sierra/msp71xx/msp_setup.c 2008-08-17 10:15:48.000000000 -0600 @@ -19,7 +19,7 @@ #include <msp_prom.h> #include <msp_regs.h> -#if defined(CONFIG_PMC_MSP7120_GW) +#if defined(CONFIG_PMC_MSP7120_GW) && defined(CONFIG_PMCMSP_GPIO) #include <msp_regops.h> #include <msp_gpio.h> #define MSP_BOARD_RESET_GPIO 9 @@ -79,7 +79,7 @@ void msp7120_reset(void) /* Wait a bit for the DDRC to settle */ for (i = 0; i < 100000000; i++); -#if defined(CONFIG_PMC_MSP7120_GW) +#if defined(CONFIG_PMC_MSP7120_GW) && defined(CONFIG_PMCMSP_GPIO) /* * Set GPIO 9 HI, (tied to board reset logic) * GPIO 9 is the 4th GPIO of register 3
