* ATMEL: use generic mmc frameworkSven Schnelle2012-03-13-1/+0
| | | | | | | | | gen_atmel_mci works on AVR32 as well, so no need to use the legacy mmc driver. This also has the nice side effect of being able to use SDHC cards an those boards. Signed-off-by: Sven Schnelle <svens@stackframe.org> Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
* mmc: make mmc_send_status() more reliableJan Kloetzke2012-02-15-0/+2
| | | | | | | | | 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: Implement card detection.Thierry Reding2012-01-08-0/+2
| | | | | | | | | | | 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 Reding2012-01-08-1/+1
| | | | | | | | | | | | | | | | | | | | | 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.

* mmc: Access mode validation for eMMC cards > 2 GiBŁukasz Majewski2011-07-15-0/+1
| | | | | | | | | | | | | | | | This patch provides handling of the two way handshake when SEND_OP_COND (CMD1) is send to mmc card. It is necessary to inform eMMC card if the host can work with high capacity cards (Jedec JESD84-A441, point 7.4.3). The extra flag MMC_MODE_HC (high capacity) is added to indicate if the host is capable of handling the high capacity eMMC cards. Since this change is added to the generic mmc framework, then it requires other boards to indicate if their mmc controllers can handle high capacity cards. As it is now - the old behaviour of the framework is preserved. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
* MMC: add erase function to both mmc and sdLei Wen2011-07-15-0/+8
| | | | | | | | | | | Erase is a very basic function since the begin of sd specification is announced. Although we could write a bulk of full 0xff memory to the range to take place of erase, it is more convenient and safe to implement the erase function itself.

* mmc: enable partition switch function for emmcLei Wen2011-05-18-0/+8
| | | | | | | | | | | | | | | | | | | For emmc, it may have up to 7 partitions: two boot partitions, one user partition, one RPMB partition and four general purpose partitions. (Refer to JESD84-A44.pdf/page 154) As bootloader may need to read out or reflashing images on those different partitions, it is better to enable the partition switch with console command support. Also for partition would be restore to user partition(part 0) when CMD0 is used, so change mmc_init routine to perform normal initialization only once for each slot, unless use the rescan command to force init again.

* mmc_spi: generate response for send status commandThomas Chou2011-05-18-0/+1
| | | | | | | | | | A "send status" command is added with the commit "mmc: checking status after commands with R1b response". But the status register returned from send status command of SPI protocol is different from that of MMC/SD protocol. We do a simple test and generate a response in stead of full bit-by-bit translation. Signed-off-by: Thomas Chou <thomas@wytron.com.tw>

Initialize b_max to CONFIG_SYS_MMC_MAX_BLK_COUNT in mmc_register if it has not been initialized by the hw driver. Initialize b_max to 0 in all callers to mmc_register.

* mmc: SEND_OP_COND considers card capabilities (voltage)Raffaele Recalcati2011-04-13-0/+2
| | | | | | | | | | | The first SEND_OP_COND (CMD1) command added is used to ask card capabilities. After it an AND operation is done between card capabilities and host capabilities (at the moment only for the voltage field). Finally the correct value is sent to the MMC, waiting that the card exits from busy state.

* mmc: checking status after commands with R1b responseRaffaele Recalcati2011-04-13-0/+4
| | | | | | | | | | It is recommended to check card status after these kind of commands. This is done using CMD13 (SEND_STATUS) JEDEC command until the card is ready.

* fsl_esdhc: Use mmc_set_clock to set initial speedJerry Huang2010-12-18-1/+2
| | | | | | | | | | | | | | After booting the u-boot, and first using some SD card (such as Sandisk 2G SD card), because the field 'clock' of struct mmc is zero, this will cause the read transfer is always active and SDHC DATA line is always active, therefore, driver can't handle the next command. Therefore, we use mmc_set_clock to setup both the data structure and HW to the initial clock speed of 400000Hz.

* MMC: add weak function to detect MMC/SD cardStefano Babic2010-03-07-0/+1
| | | | | | | | | | | Most controllers can check if there is a card in the slot. However, they require pins that could be not available because required by other functions and the detection of a card must be performed in another way. This patch adds a weak function that a board can implement to add its internal custom way to check the presence of a MMC/SD card. Signed-off-by: Stefano Babic <sbabic@denx.de>

* mmc: fix response decoding on little endianRabin Vincent2009-06-02-3/+3
| | | | | | | | | | | | | | | | 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>
* Add MMC FrameworkAndy Fleming2009-02-16-9/+181
| | | | | | | | | | | | | | 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>
* Eliminated arch-specific mmc header requirementAndy Fleming2009-02-16-1/+52
| | | | | | | | | | The current MMC infrastructure relies on the existence of an arch-specific header file. This isn't necessary, and a couple drivers were forced to implement dummy files to meet this requirement. Instead, we move the stuff in those header files into a more appropriate place, and eliminate the stubs and the #include of asm/arch/mmc.h Signed-off-by: Andy Fleming <afleming@freescale.com>

* MMC: Consolidate MMC/SD command definitionsHaavard Skinnemoen2008-06-28-0/+24
| | | | | | | | | | | | | | | This moves the MMC and SD Card command definitions from include/asm/arch/mmc.h into include/mmc.h. These definitions are given by the MMC and SD Card standards, not by any particular architecture. There's a lot more room for consolidation in the MMC drivers which I'm hoping to get done eventually, but this patch is a start. Compile-tested for all avr32 boards as well as lpc2292sodimm and lubbock. This should cover all three mmc drivers in the tree. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
