So we +could only assume it always has a card instead of detecting SDHC_CD_B +status. This patch is to add workaround for these non-removable +cards which are used by esdhc-2. + +Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com> +--- + drivers/mmc/fsl_esdhc.c | 6 +++++- + include/fsl_esdhc.h | 1 + + 2 files changed, 6 insertions(+), 1 deletion(-) + +diff --git a/drivers/mmc/fsl_esdhc.c b/drivers/mmc/fsl_esdhc.c +index cacf879..2c6e175 100644 +--- a/drivers/mmc/fsl_esdhc.c ++++ b/drivers/mmc/fsl_esdhc.c +@@ -628,6 +628,8 @@ static int esdhc_getcd(struct mmc *mmc) + struct fsl_esdhc *regs = (struct fsl_esdhc *)cfg->esdhc_base; + int timeout = 1000; + ++ if (cfg->non_removable_card) ++ return 1; + #ifdef CONFIG_ESDHC_DETECT_QUIRK + if (CONFIG_ESDHC_DETECT_QUIRK) + return 1; +@@ -759,7 +761,9 @@ int fsl_esdhc_mmc_init(bd_t *bis) + cfg_1 = calloc(sizeof(struct fsl_esdhc_cfg), 1); + cfg_1->esdhc_base = CONFIG_SYS_FSL_ESDHC_1_ADDR; + cfg_1->sdhc_clk = gd->arch.sdhc_clk; +- ++#ifdef CONFIG_FSL_ESDHC_1_NON_REMOVABLE_CARD ++ cfg_1->non_removable_card = true; ++#endif + if (fsl_esdhc_initialize(bis, cfg)) + return -1; + if (fsl_esdhc_initialize(bis, cfg_1)) +diff --git a/include/fsl_esdhc.h b/include/fsl_esdhc.h +index 073048f..8335106 100644 +--- a/include/fsl_esdhc.h ++++ b/include/fsl_esdhc.h +@@ -175,6 +175,7 @@ struct fsl_esdhc_cfg { + #endif + u32 sdhc_clk; + u8 max_bus_width; ++ bool non_removable_card; + struct mmc_config cfg; + }; + +-- +1.7.9.5 + |
