2018-05-11scsi: ceva: Convert driver to use UCLASS_AHCI instead of SCSIMichal Simek
In v2018 the patch "dm: ahci: Correct uclass private data" (sha1: bfc1c6b4838501d10aa48c0e92eaf70976f4b2dd) was causing an issue for ceva_sata. But this issue is not in v2018.05-rc1 but still converting to UCLASS_AHCI would make more sense. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
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>

2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory.

2017-07-28dm: ahci: Avoid scsi_scan_dev() in ahci_probe_scsi()Bin Meng

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: 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.
