* mci: Add am654 SDHCI driverSascha Hauer2023-11-061-0/+1

* mci: Add dwcmshc-sdhci driverJules Maselbas2023-08-211-0/+1
| | | | | | | | | | | | | | The dwcmshc driver started as a modification of the dove-sdhci driver. This new dwcmshc driver has been heavily reworked to be closer to the rockchip-dwcmshc-sdhci driver, both drivers are for the same IP from Synopsys DesignWare Cores. This new dwcmshc driver use new features introduced in common sdhci code, mainly to support v4_mode and 64-bit DMA.

* mci: sdhci: atmel: extend driver for PBL usageAhmad Fatoum2020-07-111-0/+1
| | | | | | | | | The BootROM resets both the SD/MMC host controller and the pin controller, but the card itself remains in transfer mode. If we redo host-side setup, we can directly read new blocks off the card. Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mci: sdhci: add Atmel SDHCI (sama5d2, sam9x60) supportAhmad Fatoum2020-04-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | We already support Ethernet and QSPI on the SAMA5D2, but MMC was so far missing. Port over the at91bootstrap driver to barebox. Some parts are based on the U-Boot and Linux implementations. To support future use in PBL, the driver model and driver implementation parts are split into separate files with the latter being compilable for PBL as well. Registers, which are found in the common Linux sdhci.h have been added to the barebox sdhci.h. Registers which appear to be Atmel specific have been added to atmel-sdhci-common.c instead. The driver still misses some parts, which will follow later: - ADMA is unsupported, PIO only for now - Only the SD/MMC controller already enabled by the first stage bootloader is supported. Further clocking changes appear to be necessary to enable another Both can be retrofitted later on and don't hold us back from booting from MMC.

* mci: add Arasan SDHCI controller driverThomas Haemmerle2019-11-211-0/+1
| | | | | | | | | | | | | | | | | | | | This adds support for the Arasan SDHCI controller, which is found on the Xilinx Zynq 7000 and ZynqMP SoCs. This just adds very basic PIO read/write support. This submission is also missing the tap delay configuration, which is required for the high speed modes on the ZynqMP, but this can be added in a separate patch once it is clear how the interface for this feature should look like. The driver skeleton was provided by Michael, most of the actual driver porting work was done by Thomas and some coding style fixes and write support bug fixes added by Lucas.
