2016-05-17dm: mmc: Add a function to obtain the block deviceSimon Glass
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>
2016-05-17dm: mmc: Implement the select_hwpart() methodSimon Glass
Implement this method so that hardware partitions will work correctly with MMC. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: mmc: Move mmc_switch_part() above its callersSimon Glass
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>
2016-05-17dm: blk: Free the block device name when unboundSimon Glass
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>
2016-05-17dm: core: Allow device names to be freed automaticallySimon Glass
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>
2016-05-17dm: blk: Fix allocation of block-device numberingSimon Glass
Due to code ordering the block devices are not numbered sequentially. Fix this. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: sandbox: Enable systemaceSimon Glass
Enable building the systemace code for sandbox. This increases build coverage for sandbox. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: systemace: Add driver-mode block-device supportSimon Glass
Add support for CONFIG_BLK to the systemace driver. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: systemace: Reorder function to avoid forward declarataionsSimon Glass
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>
2016-05-17dm: blk: Add a easier way to create a named block deviceSimon Glass
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>
2016-05-17dm: blk: Allow blk_create_device() to allocate the device numberSimon Glass
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>
2016-05-17dm: sandbox: Enable SATASimon Glass
Enable building the SATA code for sandbox. This increases build coverage for sandbox. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: sata: Add support for driver-model block devicesSimon Glass
Add driver-model block-device support to the SATA implementation. This is just a dummy implementation for now, since the SATA low-level API uses numbered devices and that doesn't fit with driver model. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: sandbox: Enable SCSISimon Glass
Enable building the SCSI code for sandbox. This increases build coverage for sandbox. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: scsi: Add support for driver-model block devicesSimon Glass
Add driver-model block-device support to the SCSI implementation. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: sandbox: Enable IDESimon Glass
Enable building the IDE code for sandbox. This is for build coverage only. It does not currently work. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: ide: Add support for driver-model block devicesSimon Glass
Add driver-model block-device support to the IDE implementation. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: part: Drop the get_dev() methodSimon Glass
This is now handled by the legacy block driver. The get_dev() method is no-longer used. Drop it. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: sandbox: Drop the host_get_dev() functionSimon Glass
This function is implemented by the legacy block functions now. Drop it. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: blk: Drop the systemace.h headerSimon Glass
This has nothing of consequence. Remove it and its only inclusion site. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: systemace: Drop the get_dev() functionSimon Glass
This function is implemented by the legacy block functions now. Drop it. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: sata: Drop the get_dev() functionSimon Glass
This function is implemented by the legacy block functions now. Drop it. We cannot yet make sata_dev_desc[] private to common/sata.c as it is used by the SATA drivers. This will require the SATA interface to be reworked. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: scsi: Drop the get_dev() functionSimon Glass
This function is implemented by the legacy block functions now. Drop it. Signed-off-by: Simon Glass <sjg@chromium.org>

This function is implemented by the legacy block functions now. Drop it. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: disk: Use legacy block driver info for block device accessSimon Glass
Instead of calling xx_get_dev() functions for each interface type, use the new legacy block driver which can provide the device through its interface. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: sata: Separate the non-command code into its own fileSimon Glass
At present the SATA command code includes both the command-processing code and the core SATA functions and data structures. Separate the latter into its own file, adding functions as needed to avoid the command code accessing data structures directly. With this commit: - All CONFIG option are referenced from the non-command code - The concept of a 'current SATA device' is confined to the command code This will make it easier to convert this code to driver model. Signed-off-by: Simon Glass <sjg@chromium.org>

2016-05-17dm: scsi: Separate the non-command code into its own fileSimon Glass
At present the SCSI command code includes both the command-processing code and the core SCSI functions and data structures. Separate the latter into its own file, adding functions as needed to avoid the command code accessing data structures directly. This functions use the new legacy block functions. With this commit: - There is no CONFIG option referenced from the command code - The concept of a 'current SCSI device' is confined to the command code This will make it easier to convert this code to driver model. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: mmc: Add an implementation of the 'devnum' functionsSimon Glass
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>
2016-05-17dm: mmc: Add a legacy block interface for MMCSimon Glass

Add a legacy block interface for systemace. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: blk: Add a legacy block interfaceSimon Glass
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>
2016-05-17dm: scsi: Rename CONFIG_CMD_SCSI to CONFIG_SCSISimon Glass
This option currently enables both the command and the SCSI functionality. Rename the existing option to CONFIG_SCSI since most of the code relates to the feature. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: sata: Fix code style problems in cmd/sata.cSimon Glass
This file has a few coding style problems. Fix these to make future updates easier. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: ide: Remove the forward declarationsSimon Glass
Reorder the code to avoid needing forward declarations. Fix up code style as needed. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: ide: Correct various code style problemsSimon Glass
Adjust common/ide.c so that it passes most checkpatch.pl checks. Signed-off-by: Simon Glass <sjg@chromium.org>

Reorder the code to avoid needing forward declarations. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17sandbox: Add dummy SATA functionsSimon Glass
Add some functions needed by the SATA code. This allows it to be compiled for sandbox, thus increasing build coverage. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17sandbox: Add dummy SCSI functionsSimon Glass
Add some functions needed by the SCSI code. This allows it to be compiled for sandbox, thus increasing build coverage. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17sandbox: Add string and 16-bit I/O functionsSimon Glass
Add outsw() and insw() functions for sandbox, as these are needed by the IDE code. The functions will not do anything useful if called, but allow the code to be compiled. Also add out16() and in16(), required by systemace. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17Allow iotrace byte access to use an address of any sizeSimon Glass
If an address is used with readb() and writeb() which is smaller than the expected size (e.g. 32-bit value on a machine with 64-bit addresses), a warning results. Fix this by adding a cast. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: Rename disk uclass to ahciSimon Glass
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>
2016-05-17pci: Drop CONFIG_SYS_SCSI_SCAN_BUS_REVERSESimon Glass
This option is not used by any board. Drop it. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2016-05-17dm: sandbox: Add a board for sandbox without CONFIG_BLKSimon Glass
While the driver-model block device support is in progress, it is useful to build sandbox both with and without CONFIG_BLK. Add a separate board for the latter. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17Revert "dm: sandbox: Drop the pre-DM host implementation"Simon Glass
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>
