2017-07-11dm: core: Add functions to obtain node's address/size cellsSimon Glass
The of_n_addr_cells() and of_n_size_cells() functions are useful for getting the size of addresses in a node, but in a few places U-Boot needs to obtain the actual property value for a node without walking up the stack. Add functions for this and just the existing code to use it. Add a comment to the existing ofnode functions which do not do the right thing with a flat tree. This fixes a problem reading PCI addresses. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Marcel Ziswiler <marcel.ziswiler@toradex.com> Tested-on: Beaver, Jetson-TK1
2017-07-11dm: core: Add dev_read_enabled() to check if a device is enabledSimon Glass
This function allows a device's status to be read. This indicates whether the device should be enabled or disabled.

2017-07-11dm: core: Add dev_read_resource() to read device resourcesSimon Glass
Add a function which reads resources from a device, such as the device hardware address. This uses the "reg" property in the device. Unlike other functions there is little sense in inlining this when livetree is not being used because it has some logic in it and this would just bloat the code size.

2017-07-11dm: ahci: Add a driver for SCSI on AHCISimon Glass
Some AHCI drivers use SCSI under the hood. Rather than making the AHCI driver be in the SCSI uclass it makes sense to have the AHCI device create a SCSI device as a child. That way we can handle any AHCI-specific operations rather than trying to pretend tha the device is just SCSI. To handle this we need to provide a way for AHCI drivers to bind a SCSI device as its child, and probe it. Add functions for this.

2017-07-11dm: scsi: Split out the bus scanning codeSimon Glass
Split out the code that scans a single SCSI bus into a separate function. This will allow it to be used from driver model. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

Change this function to return an error number instead of true/false. This allows us to return a proper error number. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2017-07-11dm: scsi: Add operations for SCSI devicesSimon Glass
The SCSI uclass currently has no operations. It just uses the global SCSI functions. Fix this by adding operations to the only two drivers that use the uclass, and replacing the global functions with those defined locally in the SCSI code.

2017-07-11dm: ahci: Create a local version of two SCSI functionsSimon Glass
With driver model we need to define implementations of exec() and bus_reset() separately for each SCSI driver. As a first step, create a local version of each function in the AHCI driver and call each from its global version.

2017-07-11dm: scsi: Document and rename the scsi_scan() parameterSimon Glass
The 'mode' parameter is actually a flag to determine whether to display a list of devices found during the scan. Rename it to reflect this, add a function comment and adjust callers to use a boolean. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2017-07-11dm: scsi: Add a device pointer to scan_exec(), scsi_bus_reset()Simon Glass
With driver model these functions need a device pointer. Add one even when CONFIG_DM_SCSI is not defined. This avoids having ugly conditional function prototypes, When CONFIG_DM_SCSI is not defined we can just ignore the pointer.

2017-07-11dm: ahci: Drop use of probe_entSimon Glass
With driver model we cannot have static data or assume that there is only one device of each time. Adjust the code so that 'probe_ent' is not needed with driver model. Add a new ahci_init_dm() function which can init AHCI for driver model without re-allocating the uclass data. Move over the only existing driver to use this new function.

2017-07-11dm: ahci: Unwind the confusing init codeSimon Glass
Two AHCI drivers use SCSI with CONFIG_DM_SCSI. The SCSI uclass calls scsi_low_level_init() which is implemented by ahci.c. If CONFIG_SCSI_AHCI_PLAT is defined it does one thing and if it is not it does something else. We don't need to call through scsi_low_level_init() to get the init completed. Instead, adjust the two drivers to call into AHCI directly. Drop the post-probe init in the SCSI uclass. This means that driver model doesn't need to use scsi_low_level_init(). It is a legacy function and driver model should use a driver's probe() method instead. While we are here, add a comment to the top of the file explaining what ahci.c does.

These are very confusing without some sort of indentation. At some point we will be able to remove them, but for now, indent them. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2017-07-11dm: ahci: Refactor to avoid static variablesSimon Glass
With driver model we need each device to have its own state. As a step towards this, restrict use of the global 'probe_ent' to just a few places in the file. This will allow us to add driver-model functions which can pass the correct data around. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2017-07-11dm: sata: Move ataid into struct ahci_uc_privSimon Glass

2017-07-11dm: ahci: Rename struct ahci_probe_entSimon Glass
This is not a very useful name since once it is probed it still hangs around. With driver model we will use uclass data for this, so rename the struct. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2017-07-11dm: scsi: Use the uclass platform dataSimon Glass
At present the two driver-model SCSI drivers use device platform data to store information that relates to the uclass. It is better to use uclass platform data in this situation. Update the code to do this. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
