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>
2017-07-11dm: 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: 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: 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>
2017-07-11scsi: Move drivers into new drivers/scsi directorySimon Glass
At present we have the SCSI drivers in the drivers/block and common/ directories. It is better to split them out into their own place. Use drivers/scsi which is what Linux does. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
