From ba1b041bd138573096cddedc2d58e9ba4d0a5a21 Mon Sep 17 00:00:00 2001 From: Kinsey Moore Date: Mon, 26 Sep 2022 15:52:57 -0500 Subject: rtemsbsd/arasan_sdhci: Stop masking capabilities The initial version of this driver was masking the capabilities register to hide 8 bit bus capability. This is not necessary since these devices report that capability correctly and the masking affects performance negatively on ZynqMP boards where the 8 bit bus is supported. This also removes two quirks that were made necessary by the capabilities masking. --- rtemsbsd/sys/dev/sdhci/arasan_sdhci.c | 13 +------------ 1 file changed, 1 insertion(+), 12 deletions(-) diff --git a/rtemsbsd/sys/dev/sdhci/arasan_sdhci.c b/rtemsbsd/sys/dev/sdhci/arasan_sdhci.c index 6332260a..9dcab3b1 100644 --- a/rtemsbsd/sys/dev/sdhci/arasan_sdhci.c +++ b/rtemsbsd/sys/dev/sdhci/arasan_sdhci.c @@ -123,16 +123,8 @@ static uint32_t arasan_sdhci_read_4(device_t dev, struct sdhci_slot *slot, bus_size_t off) { struct arasan_sdhci_softc *sc = device_get_softc(dev); - uint32_t val32, wrk32; - val32 = RD4(sc, off); - - if (off == SDHCI_CAPABILITIES) { - val32 &= ~SDHCI_CAN_DO_8BITBUS; - return (val32); - } - - return val32; + return (RD4(sc, off)); } static void @@ -287,9 +279,6 @@ arasan_sdhci_attach(device_t dev) goto fail; } - sc->slot.quirks |= SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK; - sc->slot.quirks |= SDHCI_QUIRK_BROKEN_AUTO_STOP; - /* * DMA is not really broken, it just isn't implemented yet. */ -- cgit v1.2.3
