* mmc: store hwpart in the block deviceStephen Warren2016-01-13-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will allow us to have multiple block device structs each referring to the same eMMC device, yet different HW partitions. For now, there is still a single block device per eMMC device. As before, this block device always accesses whichever HW partition was most recently selected. Clients wishing to make use of multiple block devices referring to different HW partitions can simply take a copy of this block device once it points at the correct HW partition, and use each one as they wish. This feature will be used by the next patch. In the future, perhaps get_device() could be enhanced to return a dynamically allocated block device struct, to avoid the client needing to copy it in order to maintain multiple block devices. However, this would require all users to be updated to free those block device structs at some point, which is rather a large change. Most callers of mmc_switch_part() wish to permanently switch the default MMC block device's HW partition. Enhance mmc_switch_part() so that it does this. This removes the need for callers to do this. However, common/env_mmc.c needs to save and restore the current HW partition. Make it do this more explicitly. Replace use of mmc_switch_part() with mmc_select_hwpart() in order to remove duplicate code that skips the call if that HW partition is already selected.

* dm: Convert PCI MMC over to use DM PCI APISimon Glass2016-01-12-4/+2
| | | | | | | | | | | | | | At present pci_mmc_init() does not correctly use the PCI function since the list it passes is not terminated. The array size passed to pci_mmc_init() is actually not used correctly. Fix this and adjust the pci_mmc_init() to scan all available MMC devices. Adjust this code to use the new driver model PCI API. This should move over to the new MMC uclass at some point. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

* mmc: Fix splitting device initializationAndrew Gabbasov2015-05-05-2/+1
| | | | | | | | | | | | | | Starting part of device initialization sets the init_in_progress flag only if the MMC card did not yet come to ready state and needs to continue polling. If the card is SD or if the MMC card became ready quickly, the flag is not set and (if using pre-initialization) the starting phase will be re-executed from mmc_init function. Set the init_in_progress flag in all non-error cases. Also, move flags setting statements around so that the flags are not set in error paths. Also, IN_PROGRESS return status becomes unnecessary, so get rid of it. Signed-off-by: Andrew Gabbasov <andrew_gabbasov@mentor.com>
* mmc: Avoid extra duplicate entry in mmc device structureAndrew Gabbasov2015-05-05-1/+0
| | | | | | | | | | | | | The 'op_cond_response' field in mmc structure contains the response from the last SEND_OP_COND MMC command while making iterational polling of the card. Later it is copied to 'ocr' field, designed to contain the OCR register value, which is actually the same response from the same command. So, these fields have actually the same data, just in different time periods. It's easier to use the same 'ocr' field in both cases at once, without temporary using of the 'op_cond_response' field.

As the different attributes and partitioning options on eMMC may be interdependent validation has to be done based on the complete partitioning configuration. The function accepts three modes: - MMC_HWPART_CONF_CHECK: just validates that the configuration is valid. - MMC_HWPART_CONF_SET: validates and sets all the fields in EXT_CSD but without setting the "partitioning completed" bit, and thus is reversible. - MMC_HWPART_CONF_COMPLETE: does everything and is thus not reversible.

* mmc: Fix handling of bus widths and DDR card capabilitiesAndrew Gabbasov2014-12-12-0/+1
| | | | | | | | | | | | | | | | | | | | | | | If the MMC_MODE_DDR_52MHz flag is set in card capabilities bitmask, it is never cleared, even if switching to DDR mode fails, and if the controller driver uses this flag to check the DDR mode, it can take incorrect actions. Also, DDR related checks in mmc_startup() incorrectly handle the case when the host controller does not support some bus widths (e.g. can't support 8 bits), since the host_caps is checked for DDR bit, but not bus width bits. This fix clearly separates using of card_caps bitmask, having there the flags for the capabilities, that the card can support, and actual operation mode, described outside of card_caps (i.e. bus_width and ddr_mode fields in mmc structure). Separate host controller drivers may need to be updated to use the actual flags. Respectively, the capabilities checks in mmc_startup are made more correct and clear. Also, some clean up is made with errors handling and code syntax layout. Signed-off-by: Andrew Gabbasov <andrew_gabbasov@mentor.com>

On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long.

* mmc: add setdsr supportMarkus Niebel2014-01-09-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The eMMC and the SD-Card specifications describe the optional SET_DSR command. During measurements at our lab we found that some cards implementing this feature having really strong driver strengts per default. This can lead to voltage peaks above the specification of the host on signal edges for data sent from a card to the host. Since availability of a given card type may be shorter than the time a certain hardware will be produced it is useful to have support for this command (Alternative would be changing termination resistors and adapting the driver strength of the host to the used card.) Following proposal for an implementation: - new field that reflects CSD field DSR_IMP in struct mmc - new field for design specific DSR value in struct mmc - board code can set DSR value in mmc struct just after registering an controller - mmc_startup sends the the stored DSR value before selecting a card, if DSR_IMP is set Additionally the mmc command is extended to make is possible to play around with different DSR values. The concept was tested on a i.MX53 based platform using a Micron eMMC card where the default DSR is 0x0400 (12mA) but in our design 0x0100 (0x0100) were enough. To use this feature for instance on a mx53loco one have to add a call to mmc_set_dsr() in board_mmc_init() after calling fsl_esdhc_initialize() for the eMMC.
