SPDX: Convert all of our single license tags to Linux Kernel style 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.

dm: treewide: Rename ..._platdata variables to just ..._plat Try to maintain some consistency between these variables by using _plat as a suffix for them. Signed-off-by: Simon Glass <sjg@chromium.org> 2020-12-03 23:55:23 +00:00			`struct ich6_bank_plat {`
x86: ich6-gpio: Add Intel Tunnel Creek GPIO support Intel Tunnel Creek GPIO register block is compatible with current ich6-gpio driver, except the offset and content of GPIO block base address register in the LPC PCI configuration space are different. Use u16 instead of u32 to store the 16-bit I/O address of the GPIO registers so that it could support both Ivybridge and Tunnel Creek.

x86: ivybridge: Add support for early GPIO init When not relying on Coreboot for GPIO init the GPIOs must be set up correctly. This is currently done statically through a rather ugly method. As the GPIOs are figured out they can be moved to the device tree and set up as needed rather than all at the start. In this implementation, board files should call ich_gpio_set_gpio_map() before the GPIO driver is used in order to provide the GPIO information. We use the early PCI interface so that this driver can now be used before relocation. Signed-off-by: Simon Glass <sjg@chromium.org> 2014-11-13 05:42:24 +00:00			`const char *bank_name;`
x86: gpio: Correct GPIO setup ordering The Intel GPIO driver can set up the GPIO pin mapping when the first GPIO is probed. However, it assumes that the first GPIO to be probed is in the first GPIO bank. If this is not the case then the init will write to the wrong registers. Fix this. Also add a note that this code is deprecated. We should move to using device tree instead.
