* MMC: Implement generic bounce bufferMarek Vasut2012-03-29-3/+99
| | | | | | | | | | This implements generic bounce buffer at the end of MMC command submission chain. Therefore if unaligned data are passed, they are copied. This stuff should be pushed down into the MMC subsystem to squash all places generating these unaligned data. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Andy Fleming <afleming@gmail.com>

* mmc: make mmc_send_status() more reliableJan Kloetzke2012-02-15-8/+12
| | | | | | | | | Align the card status polling with the Linux kernel and retry the command at least five times. Also some cards apparently mishandle the status bits, so make sure to check the card state too. Signed-off-by: Jan Kloetzke <jan.kloetzke@dspg.com> Cc: Andy Fleming <afleming@gmail.com>
* mmc: fix card busy pollingJan Kloetzke2012-02-15-8/+6
| | | | | | | | | | | | A MMC/SD card may always go into the programming state (and hence be busy) after a block write. Therefore always check the card state, even after single block writes. On the other hand there is no need to check the card status after a read. Also make sure that errors during busy polling are propagated upwards.

* Tegra: mmc: Fixed handling of interrupts in timeouts.Tom Warren2012-02-15-0/+4
| | | | | | | | | | | | | We are seeing occasional timeouts in the Tegra mmc code when we are reading from external MMC cards. These don't seem to be detrimental if they are handled properly. This CL properly clears the "normal interrupt status register" (norintsts) in error conditions. If we don't do this, when we come back into mmc_send_cmd() the register will still contain status from the last transaction.

* omap_hsmmc: Wait for CMDI to be clearTom Rini2012-02-15-2/+3
| | | | | | | | | | | | | | | | | Before we can send a command we need both the DATI (command inhibit on mmc_dat line) bit and CMDI (command inhibit on mmc_cmd line) are clear. 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. DATI_CMDDIS is removed as it was unused elsewhere in the code and stood for 'DATI is set, cmds are disabled still'. Fix originally spotted by Peter Bigot. Tested-by: Peter A.

* mmc: access mxcmmc from mx31 boardsHelmut Raiger2012-02-12-5/+3
| | | | | | | | | | | | | | | | | This patch modifies mxcmmc.c to be used not only by i.MX27 but also by i.MX31 boards. Both use the same SD controller, but have different clock set-ups. The i.MX27 imx_get_XXXclock functions are made static to generic.c and a public mxc_get_clock() function is provided. Pins, base address and prototypes for an i.MX31 specific board_init_mmc() are provided. Some of the i.MX27 clock getters are unused and marked as such to avoid warnings (./MAKEALL -s mx27), but the code was left in for future use.

* fsl_esdhc: fix PIO mode transfersIra Snyder2012-01-08-1/+2
| | | | | | | | | | | | | | | | 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.

* mmc: tegra2: Implement card-detect hook.Thierry Reding2012-01-08-19/+13
| | | | | | | | | | On Tegra2, card-detection is implemented by passing the card-detection GPIOs to the MMC driver at initialization time. Instead of implementing the board_mmc_getcd() function, use the card-detect hook and allow boards to override it by providing their own board_mmc_getcd() implementation.

* mmc: fsl_esdhc: Implement card-detect hook.Thierry Reding2012-01-08-17/+12
| | | | | | | | | | | | | | | | 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.

* mmc: Implement card detection.Thierry Reding2012-01-08-0/+31
| | | | | | | | | | | Check for card detect each time an MMC/SD device is initialized. If card detection is not implemented, this code behaves as before and continues assuming a card is present. If no card is detected, has_init is reset for the MMC/SD device (to force initialization next time) and an error is returned.

* mmc: Change board_mmc_getcd() function prototype.Thierry Reding2012-01-08-5/+7
| | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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.

* | MMC: PL180: Fix infinite loop with VExpress extended fifo implementationJon Medhurst (Tixy)2011-11-08-26/+0
|/ | | | | | | | | | | | | | | | | | | The new IO FPGA implementation for Versatile Express contains an MMCI (PL180) cell with the FIFO extended to 128 words. This causes the read_bytes() function to go into an infinite loop; as it will wait for for the half-full signal (SDI_STA_RXFIFOBR) if there are more than 8 words remaining (SDI_FIFO_BURST_SIZE), but it won't receive this signal once there are fewer than 64 words left to transfer. One possible fix is to add some build time configuration to change SDI_FIFO_BURST_SIZE for the new implementation. However, the problematic code only seems to exist as a small performance optimisation, so the solution implemented by this patch is to simply remove it. The error checking following the loop is also removed as this will be handled by code further down the function.

* mmc: mv_sdhci: fix 8bus width access for 88SV331xV5Lei Wen2011-11-03-0/+33
| | | | | | | | | | | | Marvell 88SV331xV5 platform's sdhci host control is not very standard with the spec in the 8bit handling. It need to set its private register to switch to the 8bit mode which is not included in the standard sdhci registers. This patch mainly hacks the writeb method, and set its private register if it find the driver is going to switch to the 8bit mode. Signed-off-by: Lei Wen <leiwen@marvell.com>
* mmc: retry the cmd8 to meet 74 clocks requirement in the specLei Wen2011-11-03-2/+14
| | | | | | | | | | For some controller it has dynamic clock gating, and only toggle out clk when the first cmd0 send out, while some card strictly obey the 74 clocks rule, the interval may not be sufficient between the cmd0 and this cmd8, retry to fulfil the clock requirement.
