* dm: mmc: Add a way to use driver model for MMC operationsSimon Glass2016-07-11-1/+65
| | | | | | | | | | | | The driver model conversion for MMC has moved in small steps. The first step was to have an MMC device (CONFIG_DM_MMC). The second was to use a child block device (CONFIG_BLK). The final one is to use driver model for MMC operations (CONFIG_DM_MMC_OP). Add support for this. The immediate priority is to make all boards that use DM_MMC also use those other two options. This will allow them to be removed. Signed-off-by: Simon Glass <sjg@chromium.org>

* 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.

* 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.

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>
