2019-02-20pch: Add ioctl supportSimon Glass
At present the PCH has 4 operations and these are reasonably widely used in the drivers. But sometimes we want to add rarely used operations, and each of these currently adds to the size of the PCH operations table. Add an ioctl() method which can be easily expanded without any more impact on the operations table. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2019-02-20sandbox: pch: Add a test for the PCH uclassSimon Glass
This uclass currently has no tests. Add a sandbox driver and some simple tests to provide basic coverage.

2019-02-20x86: sandbox: pch: Add a CONFIG option for PCHSimon Glass
At present this uclass is selected only on x86. In order to add a test for it, it must also support sandbox. Create a new CONFIG_PCH option and enable it on x86 and sandbox. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.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>
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>
2016-07-27dm: Use dm_scan_fdt_dev() directly where possibleSimon Glass
Quite a few places have a bind() method which just calls dm_scan_fdt_dev(). We may as well call dm_scan_fdt_dev() directly. Update the code to do this. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-07-27dm: Convert users from dm_scan_fdt_node() to dm_scan_fdt_dev()Simon Glass
This new function is more convenient for callers, and handles pre-relocation situations automatically. Signed-off-by: Simon Glass <sjg@chromium.org>

On some newer chipset (eg: BayTrail), there is an IO base address register on the PCH device which configures the base address of a memory-mapped I/O controller. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>

2016-02-05dm: pch: Remove pch_get_version opBin Meng
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: Expand the uclass for Platform Controller Hubs (PCH)Simon Glass
A Platform Controller Hub is an Intel concept - it is like the peripherals on an SoC and is often in a separate chip from the CPU. The chip is typically found on the first PCI bus and integrates multiple devices. We have a very simple uclass to support PCHs. Add a few operations, such as setting up the devices on the PCH and finding the SPI controller base address. Also move it into drivers/pch/ since we will be adding a few PCH drivers.
