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>
2018-04-27Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTRTom Rini
We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini <trini@konsulko.com>
2017-10-01usb: sandbox: Fix emulator device select logic in usb_emul_find_devnum()Bin Meng
Current emulator select logic in usb_emul_find_devnum() is to test the USB address. The USB address of the device being enumerated is initialized to zero at the beginning of the enumeration process in usb_setup_device(). At this point, the saved USB address in the platform data has not been assigned to any valid USB address either. This means: the logic will select an emulator device according to its sequence of declaring order in the device tree. Take test.dts for example, flash-stick@0 will be selected before flash-stick@1. But unfortunately such logic is wrong. In fact USB devices show up in a random order during the enumeration which means usb_emul_find_devnum() may be called on port 3 for keyb@3 before on port 0 for flash-stick@0. To fix this, we introduce a new emulator uclass specific platdata to store the USB device's port number on its parent hub, and update the logic to test the port number instead.

2017-10-01usb: sandbox: Initialize root hub's device speed to high speedBin Meng
At present 'usb tree' shows that the root hub on the Sandbox USB controller is at full speed. But its device descriptor says it's USB 2.0, so let's report it as a high speed device. Signed-off-by: Bin Meng <bmeng.cn@gmail.com>
