| * dm: mmc: sandbox: Add an SD-card emulationSimon Glass2016-05-172-2/+143
| | | | | | | | | | | | | | | | Add an emulation of an SD card to sandbox, allowing MMC to be used in tests. The emulation is very simple, supporting only card detection and reading test data. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: mmc: Add support for driver-model block devicesSimon Glass2016-05-173-12/+54
| | | | | | | | | | | | | | Add support for enabling CONFIG_BLK with MMC. This involves changing a few functions to use struct udevice and adding a MMC block device driver. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: mmc: Add a way to bind MMC devices with driver modelSimon Glass2016-05-171-0/+48
| | | | | | | | | | | | | | | | | | | | Binding an MMC device when CONFIG_BLK is enabled requires that a block device be bound as a child of the MMC device. Add a function to do this. The mmc_create() method will be used only when DM_BLK is disabled. Add an unbind method also. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: mmc: Implement the MMC functions for block devicesSimon Glass2016-05-172-1/+109
| | | | | | | | | | | | | | | | Implement the functions in mmc_legacy.c for driver-model block devices, so that MMC can use driver model for these. This allows CONFIG_BLK to be enabled with DM_MMC. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: sandbox: Only enable the sandbox MMC driver when validSimon Glass2016-05-171-0/+4
| | | | | | | | | | | | | | This driver will require generic MMC and block-device support in a future commit. To avoid test errors, make this change now. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: mmc: Adjust mmc_switch_part() to use a struct mmcSimon Glass2016-05-171-8/+4
| | | | | | | | | | | | | | Instead of looking up the MMC device by number, just pass it in. This makes it possible to use this function with driver model. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: mmc: Move the device list into a separate fileSimon Glass2016-05-175-117/+172
| | | | | | | | | | | | | | | | | | At present the MMC subsystem maintains its own list of MMC devices. This cannot work with driver model, which needs to maintain this itself. Move the list code into a separate 'legacy' file. The core MMC code remains, and will be shared with the driver-model implementation. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: mmc: Set up the device pointer when using the MMC uclassSimon Glass2016-05-176-1/+11
| | | | | | | | | | | | | | Update the existing drivers to set up this new pointer. This will be required by the MMC uclass. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: blk: Add functions to select a hardware partitionSimon Glass2016-05-171-0/+29
| | | | | | | | | | | | | | | | The block device uclass does not currently support selecting a particular hardware partition but this is needed for MMC. Add it so that the blk API can support MMC properly. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: mmc: Use the new select_hwpart() APISimon Glass2016-05-173-7/+13
| | | | | | | | | | | | Avoid calling directly into the MMC code - use the new API call instead. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: mmc: spl: Use the legacy block interface in SPLSimon Glass2016-05-171-0/+1
| | | | | | | | | | | | | | Bring this in for SPL so that we can use generic code for loading from block devices. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: mmc: Add a function to obtain the block deviceSimon Glass2016-05-171-0/+5
| | | | | | | | | | | | | | | | The MMC block device is contained within struct mmc. But with driver model this will not be the case. Add a function to obtain the block device. We can later implement this for CONFIG_BLK. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: mmc: Implement the select_hwpart() methodSimon Glass2016-05-171-0/+22
| | | | | | | | | | | | | | Implement this method so that hardware partitions will work correctly with MMC. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: mmc: Move mmc_switch_part() above its callersSimon Glass2016-05-171-24/+21
| | | | | | | | | | | | | | | | This function is defined after it is used. In preparation for making it static, move it up a little. Also drop the printf() which should not appear in a driver. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: blk: Free the block device name when unboundSimon Glass2016-05-171-2/+10
| | | | | | | | | | | | | | Mark the device name as allocated so that it will be freed correctly when the device is unbound. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: core: Allow device names to be freed automaticallySimon Glass2016-05-172-0/+8
| | | | | | | | | | | | | | | | | | | | Some devices have a name that is stored in allocated memory. At present there is no mechanism to free this memory when the device is unbound. Add a device flag to track whether a name is allocated and a function to add the flag. Free the memory when the device is unbound. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: blk: Fix allocation of block-device numberingSimon Glass2016-05-171-9/+9
| | | | | | | | | | | | | | Due to code ordering the block devices are not numbered sequentially. Fix this. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | Add support for CONFIG_BLK to the systemace driver. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: systemace: Reorder function to avoid forward declarataionsSimon Glass2016-05-171-31/+26
| | | | | | | | | | | | | | Move the systemace_get_dev() function below systemace_read() so that we can avoid a forward declaration. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: blk: Add a easier way to create a named block deviceSimon Glass2016-05-171-0/+15
| | | | | | | | | | | | | | | | Add a function that automatically builds the device name given the parent and a supplied string. Most callers will want to do this, so putting this functionality in one place makes more sense. Signed-off-by: Simon Glass <sjg@chromium.org>
| * dm: blk: Allow blk_create_device() to allocate the device numberSimon Glass2016-05-171-0/+29
| | | | | | | | | | | | | | | | Allow a devnum parameter of -1 to indicate that the device number should be alocated automatically. The next highest available device number for that interface type is used. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | Now that the MMC code accesses devices by number, we can implement this same interface for driver model, allowing MMC to support using driver model for block devices. Add the required functions to the uclass. Signed-off-by: Simon Glass <sjg@chromium.org>

| * dm: blk: Add a legacy block interfaceSimon Glass2016-05-172-0/+265
| | | | | | | | | | | | | | | | | | | | There is quite a bit of duplicated common code related to block devices in the IDE and SCSI implementations. Create some helper functions that can be used to reduce the duplication. These rely on a linker list of interface-type drivers Signed-off-by: Simon Glass <sjg@chromium.org>

| * dm: Rename disk uclass to ahciSimon Glass2016-05-173-7/+6
| | | | | | | | | | | | | | | | This started as 'ahci' and was renamed to 'disk' during code review. But it seems that this is too generic. Now that we have a 'blk' uclass, we can use that as the generic piece, and revert to ahci for this. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | Bring this support back so that sandbox can be compiled with CONFIG_BLK. This allows sandbox to have greater build coverage during the block-device transition. This can be removed again later. This reverts commit 33cf727b1634dbd9cd68a6ebc444a88f053822d7. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many drivers use a common form of offset + flags for device tree nodes. e.g.: <&gpio1 2 GPIO_ACTIVE_LOW> This patch adds a common implementation of this type of parsing and calls it when a gpio driver doesn't supply its' own xlate routine. This will allow removal of the driver-specific versions in a handful of drivers and simplify the addition of new drivers.
