x86: cpu: Report address width from cpu_get_info()

2020-09-25T03:27:21+00:00

Add support for this new field in the common code used by most x86 CPU drivers. Signed-off-by: Simon Glass

x86: spl: Support init of a PUNIT

2019-11-02T23:20:27+00:00

The x86 power unit handles power management. Support initing this device which is modelled as a new type of system controller since there are no operations needed. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

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

2018-05-07T13:34:12+00:00

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

x86: kconfig: Select ARCH_EARLY_INIT_R in the platform Kconfig

2017-08-01T12:17:02+00:00

This is architecture-dependent early initialization hence should be put in the platform Kconfig. Signed-off-by: Bin Meng Reviewed-by: Andy Shevchenko Reviewed-by: Simon Glass

x86: Introduce minimal PMU driver for Intel MID platforms

2017-04-10T02:02:03+00:00

This simple PMU driver allows to tyrn power on and off for selected devices. In particularly Intel Tangier needs to power on SDHCI controllers in order to access to them during board initialization. In the future it might be expanded to cover other Intel MID platforms, that's why it's located under arch/x86/lib and called pmu.c.

x86: Add SCU IPC driver for Intel MID platforms

2017-04-10T02:02:03+00:00

Intel MID platforms have few microcontrollers inside SoC, one of them is so called System Controller Unit (SCU). Here is the driver to communicate with microcontroller. Signed-off-by: Vincent Tinelli Signed-off-by: Felipe Balbi Signed-off-by: Andy Shevchenko Acked-by: Simon Glass

x86: Support jumping from SPL to U-Boot

2017-02-06T03:38:46+00:00

Add a rough function to handle jumping from 32-bit SPL to 64-bit U-Boot. This still needs work to clean it up. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Drop flag_is_changable() on x86_64

This doesn't build at present and is not used in a 64-bit build. Disable it for now. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

dm: x86: Move link to use driver model for video

x86: Add support for running Intel reference code

2016-03-17T02:27:25+00:00

Intel has invented yet another binary blob which firmware is required to run. This is run after SDRAM is ready. It is linked to load at a particular address, typically 0, but is a relocatable ELF so can be moved if required. Add support for this in the build system. The file should be placed in the board directory, and called refcode.elf. Signed-off-by: Simon Glass Reviewed-by: Bin Meng
