[Y.b. Lu] The title and commit message is confusing. From the code changes, I think you can rephrase like, armv8: ls2080ardb: enable eSDHC pin mux support CONFIG_FSL_ESDHC_PIN_MUX should be enabled for ls2080ardb whose eSDHC has pin mux with DSPI. This config makes sure esdhc dts node would be fixed with disabled status if DSPI is used, in case of any mmc issue in linux. Also, esdhc should be added in default hwconfig since eSDHC is used in default. > > Signed-off-by: Yinbo Zhu <yinbo....@nxp.com> > --- > include/configs/ls2080ardb.h | 5 +++-- > 1 files changed, 3 insertions(+), 2 deletions(-) > > diff --git a/include/configs/ls2080ardb.h b/include/configs/ls2080ardb.h index > f6aa4ed..d2e80a8 100644 > --- a/include/configs/ls2080ardb.h > +++ b/include/configs/ls2080ardb.h > @@ -331,6 +331,7 @@ unsigned long get_board_sys_clk(void); > /* MMC */ > #ifdef CONFIG_MMC > #define CONFIG_SYS_FSL_MMC_HAS_CAPBLT_VS33 > +#define CONFIG_FSL_ESDHC_PIN_MUX > #endif > > #define BOOT_TARGET_DEVICES(func) \ > @@ -390,7 +391,7 @@ unsigned long get_board_sys_clk(void); #undef > CONFIG_EXTRA_ENV_SETTINGS #ifdef CONFIG_TFABOOT > #define CONFIG_EXTRA_ENV_SETTINGS \ > - "hwconfig=fsl_ddr:bank_intlv=auto\0" \ > + "hwconfig=fsl_ddr:bank_intlv=auto;esdhc\0" \ > "ramdisk_addr=0x800000\0" \ > "ramdisk_size=0x2000000\0" \ > "fdt_high=0xa0000000\0" \ > @@ -459,7 +460,7 @@ unsigned long get_board_sys_clk(void); > "bootm $load_addr#$board\0" > #else > #define CONFIG_EXTRA_ENV_SETTINGS \ > - "hwconfig=fsl_ddr:bank_intlv=auto\0" \ > + "hwconfig=fsl_ddr:bank_intlv=auto;esdhc\0" \ > "ramdisk_addr=0x800000\0" \ > "ramdisk_size=0x2000000\0" \ > "fdt_high=0xa0000000\0" \ > -- > 1.7.1 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
