When building the zmx25 target we get: Configuring for zmx25 board... generic.c:108: warning: 'get_reset_cause' defined but not used
Fix this warning by defining get_reset_cause only if CONFIG_DISPLAY_CPUINFO is defined. Signed-off-by: Fabio Estevam <[email protected]> --- Changes since v2: - Move the location of get_reset_cause Changes since v1: - Only define get_reset_cause when CONFIG_DISPLAY_CPUINFO is defined. arch/arm/cpu/arm926ejs/mx25/generic.c | 46 ++++++++++++++++---------------- 1 files changed, 23 insertions(+), 23 deletions(-) diff --git a/arch/arm/cpu/arm926ejs/mx25/generic.c b/arch/arm/cpu/arm926ejs/mx25/generic.c index 1261640..8e60a26 100644 --- a/arch/arm/cpu/arm926ejs/mx25/generic.c +++ b/arch/arm/cpu/arm926ejs/mx25/generic.c @@ -105,29 +105,6 @@ ulong imx_get_perclk (int clk) return lldiv (fref, div); } -static char *get_reset_cause(void) -{ - /* read RCSR register from CCM module */ - struct ccm_regs *ccm = - (struct ccm_regs *)IMX_CCM_BASE; - - u32 cause = readl(&ccm->rcsr) & 0x0f; - - if (cause == 0) - return "POR"; - else if (cause == 1) - return "RST"; - else if ((cause & 2) == 2) - return "WDOG"; - else if ((cause & 4) == 4) - return "SW RESET"; - else if ((cause & 8) == 8) - return "JTAG"; - else - return "unknown reset"; - -} - u32 get_cpu_rev(void) { u32 srev; @@ -153,6 +130,29 @@ u32 get_cpu_rev(void) } #if defined(CONFIG_DISPLAY_CPUINFO) +static char *get_reset_cause(void) +{ + /* read RCSR register from CCM module */ + struct ccm_regs *ccm = + (struct ccm_regs *)IMX_CCM_BASE; + + u32 cause = readl(&ccm->rcsr) & 0x0f; + + if (cause == 0) + return "POR"; + else if (cause == 1) + return "RST"; + else if ((cause & 2) == 2) + return "WDOG"; + else if ((cause & 4) == 4) + return "SW RESET"; + else if ((cause & 8) == 8) + return "JTAG"; + else + return "unknown reset"; + +} + int print_cpuinfo (void) { char buf[32]; -- 1.6.0.4 _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
