2010-08-30U-boot: MMC update.Martin LUNDHOLM
MMC has been updated with several improvements. Primarily MMC performance has been improved by using assembler code for low level FIFO handling. Also some MMC functionality has been added, e.g. support for DDR and reliable write. Data and command delay times were incremented, otherwise hangups and timeouts were observed. Tested on HREF+ 1.1 V21 and HREF+ 1.1 V32 (Micron PoP). Following WP depends on this change (more reliable SD card write support): ST-Ericsson ID: WP264488 Change-Id: Ic92abffe1640aa9375b8d43a6b8522ca8296a368 Reviewed-on: http://gerrit.lud.stericsson.com/gerrit/4056 Reviewed-by: Michael BRANDT <michael.brandt@stericsson.com> Tested-by: Michael BRANDT <michael.brandt@stericsson.com>
2010-08-11Replace MMC/SD driver to fit new framework.Ulf Hansson
IR265772: MMC driver does not detect SDHC cards. IR254201: Restructure MMC/SD driver for U8500 board according to the block device framework in mainline U-Boot. Changes to mmc framework: - Multi Block Read support in mmc framework. - Wrap Multi Block Write/Read to be able to adopt for large transaction. - Removed incorrect check in EXT CSD for high capacity MMC. - Corrected check for high capacity SD cards. - Set MMC buswidth to 8, prio of using 4. Known limitations/bugs in mmc framework: - High capacity MMC, will likely not get the correct density. - High speed is set, whether or not the host supports it or not. board/st/u8500/mmc_utils: IMPORTANT FOR DEVELOPERS: - Removed unessary U-Boot commands which is already supported in cmd_fat. - mmc_read_cmd_file: Read command.txt into bootcmd env from FAT FS in SD card. - write_partition_block: Writes the MBR if it is not already written. board/st/u8500/mmc_host[c.h]: - Implements the entire MMC/SD host driver for the PL180 block. - There is still room for optimization: Increase CLK-speed. Use high-speed for SD cards. Is GPIO setup correctly for both cards an eMMC. EarlyDrop support not fully tested. Dynamically turn on voltage/clocks to SD, not always. More... Note: - Increased read/write performance for eMMC, to around 5.4 MB/s for sequential read/write. Earlier measurements was 3.5 MB/s for read and 2.6 MB/s for write.

2009-08-09mxc-mmc: sdhc host driver for MX2 and MX3 proccessorIlya Yanok
This is a port of Linux driver for SDHC host controller hardware found on Freescale's MX2 and MX3 processors. Uses new generic MMC framework (CONFIG_GENERIC_MMC) and it looks like there are some problems with a framework (at least on LE cpus). Some of these problems are addressed in the following patches. Signed-off-by: Ilya Yanok <yanok@emcraft.com>
2009-07-29OMAP3 Move twl4030 mmc functionTom Rix
Because twl4030 now has its own device files, move and rename twl4030_mmc_config. twl4030_mmc_config initializes the twl4030 power setting to the mmc device. Because it is in the twl4030 power domain, move it out of drivers/mmc/omap3_mmc.c and into drivers/power/twl4030.c. The function was renamed to twl4030_power_mmc_init because all the functions in this file are to have the format twl4030_power_<device>_<action> In this case the suffix is mmc_init so device : mmc action : init Signed-off-by: Tom Rix <Tom.Rix@windriver.com> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Acked-by: Heiko Schocher <hs@denx.de>
2009-07-19mmc: set bus width to 1 and clock to minimum early during initializationIlya Yanok

2009-06-02mmc: fix response decoding on little endianRabin Vincent
The mmc code defines the response as an array of chars. However, it access the response bytes both as (i) an array of four uints (with casts) and (ii) as individual chars. The former case is used more often, including by the driver when it assigns the response. The char-wise accesses are broken on little endian systems because they assume that the bytes in the uints are in big endian byte order. This patch fixes this by changing the response to be an array of four uints and replacing the char-wise accesses with equivalent uint-wise accesses. Signed-off-by: Rabin Vincent <rabin@rab.in>
2009-06-02mmc: use lldiv to fix arm eabi buildRabin Vincent

2009-02-16Add MMC FrameworkAndy Fleming
Here's a new framework (based roughly off the linux one) for managing MMC controllers. It handles all of the standard SD/MMC transactions, leaving the host drivers to implement only what is necessary to deal with their specific hardware. This also hooks the infrastructure into the PowerPC board code (similar to how the ethernet infrastructure now hooks in) Some of this code was contributed by Dave Liu <daveliu@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
