2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2017-08-17dm: sata: Update the AHCI uclass to support operationsSimon Glass
At present the AHCI uclass is just a shell and we still use the global functions to access SATA. Fix this by adding operations to the uclass. Signed-off-by: Simon Glass <sjg@chromium.org>

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: 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.

2017-07-11dm: ahci: Rename struct ahci_probe_entSimon Glass

2016-12-20dm: Add support for scsi/sata based devicesMichal Simek
All sata based drivers are bind and corresponding block device is created. Based on this find_scsi_device() is able to get back block device based on scsi_curr_dev pointer. intr_scsi() is commented now but it can be replaced by calling find_scsi_device() and scsi_scan(). scsi_dev_desc[] is commented out but common/scsi.c heavily depends on it. That's why CONFIG_SYS_SCSI_MAX_DEVICE is hardcoded to 1 and symbol is reassigned to a block description allocated by uclass. There is only one block description by device now but it doesn't need to be correct when more devices are present. scsi_bind() ensures corresponding block device creation. uclass post_probe (scsi_post_probe()) is doing low level init. SCSI/SATA DM based drivers requires to have 64bit base address as the first entry in platform data structure to setup mmio_base.

2014-07-31ahci: provide sunxi SATA driver using AHCI platform frameworkIan Campbell
This enables the necessary clocks, in AHB0 and in PLL6_CFG. This is done for sun7i only since I don't have access to any other sunxi platforms with sata included. The PHY setup is derived from the Alwinner releases and Linux, but is mostly undocumented. The Allwinner AHCI controller also requires some magic (and, again, undocumented) DMA initialisation when starting a port. This is added under a suitable ifdef. This option is enabled for Cubieboard, Cubieboard2 and Cubietruck based on contents of Linux DTS files, including SATA power pin config taken from the DTS. All build tested, but runtime tested on Cubieboard2 and Cubietruck only.
