2012-07-13FSL/eSDHC: enable the clock to detect the SD cardJerry Huang
For FSL low-end processors (VVN2.2), in order to detect the SD card, we should enable PEREN, HCKEN and IPGEN to enable the clock. Otherwise, after booting the u-boot, and then inserting the SD card, the SD card can't be detected. For SDHC VVN2.3 IP, these bits are reserved, and SDCLKEN is used. And when accessing to these reserved bit, no any impact happened.

2012-07-13mmc:fix Call mmc_init() when executing mmc_get_dev()Łukasz Majewski
This code adds call to mmc_init(), for partition related commands (e.g. fatls, fatinfo etc.). It is safe to call mmc_init() multiple times since mmc->has_init flag prevents from multiple initialization. The FAT related code calls get_dev high level method and then uses elements from mmc->block_dev, which is uninitialized until the mmc_init (and thereof mmc_startup) is called. This problem appears on boards, which don't use mmc as the default place for envs Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Cc: Andy Fleming <afleming@gmail.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

2012-05-08mmc: fsl_esdhc: Poll until card is not busy anymoreDirk Behme
This patch imports parts of two patches from the Freescale U-Boot with the following commit messages: ENGR00156405 ESDHC: Add workaround for auto-clock gate errata ENGcm03648 http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/commit/drivers/mmc/imx_esdhc.c?h=imx_v2009.08_12.01.01&id=e436525a70fe47623d346bc7d9f08f12ff8ad787 The errata, not applicable to USDHC, causes ESDHC to shut off clock to the card when auto-clock gating is enabled for commands with busy signalling and no data phase. The card might require the clock to exit the busy state, so the workaround is to disable the auto-clock gate bits in SYSCTL register for such commands. The workaround also entails polling on DAT0 bit in the PRSSTAT register to learn when busy state is complete. Auto-clock gating is re-enabled at the end of busy state. ENGR00156670-1 ESDHC/USDHC: Remove delay before each cmd and some bug fixes http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/commit/drivers/mmc/imx_esdhc.c?h=imx_v2009.08_12.01.01&id=a77c6fec8596891be96b2cdbc742c9824844b92a Removed delay of 10 ms before each command. There should not be a need to have this delay after the ENGR00156405 patch that polls until card is not busy anymore before proceeding to next cmd. This patch imports the polling part of both patches. The auto-clock gating code don't apply for i.MX6 as implemented in these two patches. SYSCTL_RSTA was defined twice. Remove one definition.

2012-04-16DMA: Split the APBH DMA init into block and channel initMarek Vasut
This fixes the issue where mxs_dma_init() was called either twice or never, without introducing any new init hooks. The idea is to allow each and every device using the APBH DMA block to configure and request only the channels it uses, instead of making it call init for all the channels as is now. The common DMA block init part, which only configures the block, is then called from CPUs arch_cpu_init() call.

The previous behavior of only checking on DATI was insufficient on some cards and incorrect behavior in any case. This makes the code check for both bits being clear and makes the error print more clear as to what happened.

The pointer to the registers used to control the Freescale ESDHC MMC controller is not initialized correctly when using PIO mode. This is fixed by initializing the pointer in the same way as all other sites within the driver. Examining the commit history shows that this was broken at introduction due to a code change in upstream U-Boot to support the mx51 processor family.

On Tegra2, card-detection is implemented by passing the card-detection GPIOs to the MMC driver at initialization time.

2012-01-08mmc: fsl_esdhc: Implement card-detect hook.Thierry Reding
This card-detect hook probably doesn't work. Perhaps somebody with more knowledge about the hardware can comment on this. I think that perhaps even the complete code from esdhc_init() could go into the getcd() function instead or mmc_getcd() needs to be called at some later time after mmc_init(), which, however, would require many other drivers to change. In addition to implementing the hook, this patch also removes the call to the board_mmc_getcd() function which is now called from the MMC framework and is no longer required here.

2012-01-08mmc: Implement card detection.Thierry Reding

2012-01-08mmc: Change board_mmc_getcd() function prototype.Thierry Reding
The new API no longer uses the extra cd parameter that was used to store the card presence state. Instead, this information is returned via the function's return value. board_mmc_getcd() returns -1 to indicate that no card-detection mechanism is implemented; 0 indicates that no card is present and 1 is returned if it was detected that a card is present. The rationale for this change can be found in the following email thread: http://lists.denx.de/pipermail/u-boot/2011-November/110180.html In summary, the old API was not consistent with the rest of the MMC API which always passes a struct mmc as the first parameter. Furthermore the cd parameter was used to mean "card absence" in some implementations and "card presence" in others.

2012-01-08ftsdc010: improve performance and capabilityMacpaul Lin
This patch improve the performance by spliting flag examination code in ftsdc010_send_cmd() into 3 functions. This patch also reordered the function which made better capability to some high performance cards against to the next version of ftsdc010 hardware. Signed-off-by: Macpaul Lin <macpaul@andestech.com>
2012-01-08mmc: add host_caps checking avoid switch card improperlyMacpaul Lin
Add a host capability checking to avoid the mmc stack switch the card to HIGHSPEED mode when the card supports HIGHSPEED while the host doesn't. This patch avoid furthur transaction problem when the mmc/sd card runs different mode to the host. Signed-off-by: Macpaul Lin <macpaul@andestech.com>
2012-01-08i.mx: fsl_esdhc: add the i.mx6q supportJason Liu
The mmc host controller on the i.mx6q is called usdhc which is redesigned based on the freescale esdhc controller. The usdhc controller is almost compatible with esdhc except it adds one mix register to support debug/SD3.0 and move the low bit 0-6 of XFERTYP register to the mix control reg low bit 0-6. Thus on i.mx6q, we have the following compared with the previous soc: (can refer to RM of chapter 56.3.3) i.mx6q: mix control: bit 31 - bit 7: Added for debug/SD3.0 support bit 6 - bit 0: move in the XFERTYP register bit 6-0 on previous soc XFERTYP register: bit 31 - bit 7: the same as before, bit 6 - bit 0: no-use previous soc mix control: no XFERTYP register: bit 31 - bit 0: xfertype information Signed-off-by: Jason Liu <jason.hui@linaro.org> Cc: Andy Fleming <afleming@gmail.com> Cc: Stefano Babic <sbabic@denx.de> Acked-by: Stefano Babic <sbabic@denx.de>
2011-12-24tegra2: Move tegra2_mmc_init() prototype to public header.Thierry Reding
tegra2_mmc_init() is implemented by the Tegra2 MMC driver. Since most of the Tegra2-based boards will need to call it, this commit exports it in the new public asm/arch/mmc.h header file to prevent each board from providing its own prototype.

2011-12-09tegra2: Modify MMC driver to handle power and cd GPIOsStephen Warren
Pass the GPIO numbers for power and card detect to tegra2_mmc_init(), and modify that function to perform all required GPIO initialization. This removes the need for board files to perform these operations. Move board_mmc_getcd() into tegra2_mmc.c now that the driver knows which GPIOs to use. Update affected call-sites in seaboard.c and harmony.c. Note that this change should make all SD ports work on Harmony, since the required GPIO setup is now being performed. v4: Fix prototype of tegra2_mmc_init() in board.h to match driver change.

2011-11-25Revert "mmc: retry the cmd8 to meet 74 clocks requirement in the spec"Macpaul Lin
This reverts commit 02f3029f1810b99869254d0cf0a71946a008a728. This patch add 3 times retry to CMD8 because the Marvell mmc controller doesn't obey the power ramp up process in the SD specification 6.4.1. (Please refer to figure 6.1 and 6.2 in the specification.) The CMD0 should be send after power ramp up has been finished. However, the Marvell mmc contorller must do power ramp up after the first CMD0 command has been send. This patch also affect existing platforms like Nokia N900 and other platforms.
