From c26c80a1a4e2e2e7e4c9806e9123bf027c02f711 Mon Sep 17 00:00:00 2001 From: Nikhil Badola Date: Tue, 30 Sep 2014 11:22:43 +0530 Subject: drivers: usb: fsl: Move USB Errata checking code Move USB Errata checking code from "arch/powerpc" to architecture independent file "fsl_usb.h" so that errata(s) become independent of the architecture. For each erratum checking function for PPC arch, define a nop function for non PPC arch for successful compilation in either case Signed-off-by: Nikhil Badola Reviewed-by: York Sun --- include/fsl_usb.h | 66 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 66 insertions(+) (limited to 'include') diff --git a/include/fsl_usb.h b/include/fsl_usb.h index 1a6c9c1636..66f8934588 100644 --- a/include/fsl_usb.h +++ b/include/fsl_usb.h @@ -85,4 +85,70 @@ struct ccsr_usb_phy { #define CONFIG_SYS_FSL_USB_SQUELCH_PROG_MASK 0x07 #endif +/* USB Erratum Checking code */ +#ifdef CONFIG_PPC +static inline bool has_erratum_a006261(void) +{ + u32 svr = get_svr(); + u32 soc = SVR_SOC_VER(svr); + + switch (soc) { + case SVR_P1010: + return IS_SVR_REV(svr, 1, 0) || IS_SVR_REV(svr, 2, 0); + case SVR_P2041: + case SVR_P2040: + return IS_SVR_REV(svr, 1, 0) || + IS_SVR_REV(svr, 1, 1) || IS_SVR_REV(svr, 2, 1); + case SVR_P3041: + return IS_SVR_REV(svr, 1, 0) || + IS_SVR_REV(svr, 1, 1) || + IS_SVR_REV(svr, 2, 0) || IS_SVR_REV(svr, 2, 1); + case SVR_P5010: + case SVR_P5020: + case SVR_P5021: + return IS_SVR_REV(svr, 1, 0) || IS_SVR_REV(svr, 2, 0); + case SVR_T4240: + case SVR_T4160: + case SVR_T4080: + return IS_SVR_REV(svr, 1, 0) || IS_SVR_REV(svr, 2, 0); + case SVR_T1040: + return IS_SVR_REV(svr, 1, 0); + case SVR_T2080: + case SVR_T2081: + return IS_SVR_REV(svr, 1, 0); + case SVR_P5040: + return IS_SVR_REV(svr, 1, 0); + } + + return false; +} + +static inline bool has_erratum_a007075(void) +{ + u32 svr = get_svr(); + u32 soc = SVR_SOC_VER(svr); + + switch (soc) { + case SVR_B4860: + case SVR_B4420: + return IS_SVR_REV(svr, 1, 0) || IS_SVR_REV(svr, 2, 0); + case SVR_P1010: + return IS_SVR_REV(svr, 1, 0); + case SVR_P4080: + return IS_SVR_REV(svr, 2, 0) || IS_SVR_REV(svr, 3, 0); + } + return false; +} +#else +static inline bool has_erratum_a006261(void) +{ + return false; +} + +static inline bool has_erratum_a007075(void) +{ + return false; +} + +#endif #endif /*_ASM_FSL_USB_H_ */ -- cgit v1.2.3
