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

2018-05-07T13:34:12Z

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: Rename PORT_RESET to IO_PORT_RESET

2016-03-17T02:27:24Z

This same name is used in USB. Add a prefix to distinguish it. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Add multi-processor init

2015-04-30T22:13:38Z

Most modern x86 CPUs include more than one CPU core. The OS normally requires that these 'Application Processors' (APs) be brought up by the boot loader. Add the required support to U-Boot to init additional APs. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Implement reset_cpu() correctly for modern CPUs

2015-04-30T03:02:31Z

The existing code is pretty ancient and is unreliable on modern hardware. Generally it will hang. We can use port 0xcf9 to initiate reset on more modern hardware (say in the last 10 years). Update the reset_cpu() function to do this, and add a new 'full reset' function to perform a full power cycle. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Add GDT descriptors for option ROMs

2014-11-25T13:34:14Z

Option ROMs require a few additional descriptors. Add these, and remove the enum since we now have to access several descriptors from assembler. Signed-off-by: Simon Glass

x86: Put global data on the stack

2012-11-28T19:40:03Z

Putting global data on the stack simplifies the init process (and makes it slightly quicker). During the 'flash' stage of the init sequence, global data is in the CAR stack. After SDRAM is initialised, global data is copied from CAR to the SDRAM stack Signed-off-by: Graeme Russ Signed-off-by: Simon Glass
