uclass: cpu: Add new API to get udevice for current CPU

2020-05-03T13:45:49+00:00

When running on SoC with multiple clusters, the boot CPU may
not be fixed, saying booting from cluster A or cluster B.
Add a API that can return the udevice for current boot CPU.
Cpu driver needs to implement is_current_cpu interface for this
feature, otherwise the API only returns the first udevice in
cpu uclass.

cpu: Support querying the address width

2020-04-16T06:36:28+00:00

Different CPUs may support different address widths, meaning the amount of
memory they can address. Add a property for this to the cpu_info struct.

This adds a timebase_freq member to the 'struct cpu_platdata', to
hold the "timebase-frequency" value in the cpu or /cpus node.

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.

cpu: Add get_vendor callback

2016-10-19T07:01:51+00:00

The CPU udevice already has a few callbacks to retreive information
about the currently running CPUs. This patch adds a new get_vendor()
call that returns the vendor of the main CPUs.

For SMBIOS tables we need to know the CPU family as well as CPU IDs. This
patches allocates some space for them in the cpu device and populates it
on x86.

cpu: Add support for microcode version and CPU ID

2016-03-17T02:27:22+00:00

Some CPUs use microcode and each core can have a different version of
microcode loaded. Also some CPUs support the concept of an integer ID used
for identification purposes. Add support for these in the CPU uclass.
