2021-02-02common: Drop asm/global_data.h from common headerSimon Glass1-0/+1
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
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>

2016-02-05dm: pch: Remove pch_get_version opBin Meng1-6/+0
pch_get_version op was only used by the ich spi controller driver, and does not really provide a good identification of pch controller so far, since we see plenty of Intel PCH chipsets and one differs from another a lot, which is not simply either a PCHV_7 or PCHV_9. Now that ich spi controller driver was updated to not get such info from pch, the pch_get_version op is useless now.

2016-01-24dm: x86: spi: Convert ICH SPI driver to driver model PCI APISimon Glass1-1/+46
At present this SPI driver works by searching the PCI buses for its peripheral. It also uses the legacy PCI API. In addition the driver has code to determine the type of Intel PCH that is used (version 7 or version 9). Now that we have proper PCH drivers we can use those to obtain the information we need. While the device tree has a node for the SPI peripheral it is not in the right place. It should be on the PCI bus as a sub-peripheral of the LPC device. Update the device tree files to show the SPI controller within the PCH, so that PCI access works as expected.

2015-04-18dm: x86: pci: Convert chromebook_link to use driver model for pciSimon Glass1-1/+23
Move chromebook_link over to driver model for PCI. This involves: - adding a uclass for platform controller hub - removing most of the existing PCI driver - adjusting how CPU init works to use driver model instead - rename the lpc compatible string (it will be removed later) This does not really take advantage of driver model fully, but it does work. Furture work will improve the code structure to remove many of the explicit calls to init the board. Signed-off-by: Simon Glass <sjg@chromium.org>
