Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36+00:00

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

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.

x86: Remove SMP limitation in lapic_setup()

2016-05-23T07:27:41+00:00

At present LAPIC is enabled and configured as virtual wire mode
in lapic_setup() only when CONFIG_SMP is on. This limitation is
however not necessary as for uniprocessor this is still needed.

x86: Don't touch IA32_APIC_BASE MSR on Intel Quark

2016-05-23T07:27:41+00:00

Intel Quark processor core provides an integrated Local APIC but
does not support the IA32_APIC_BASE MSR. As a result, the Local
APIC is always globally enabled and the Local APIC base address
is fixed at 0xfee00000. Attempting to access the IA32_APIC_BASE
MSR causes a general protection fault.

x86: Remove inline for lapic access routines

2015-07-15T00:03:17+00:00

Remove inline for lapic access routines and expose lapic_read()
& lapic_write() as APIs to read/write lapic registers. Also move
stop_this_cpu() to mp_init.c as it has nothing to do with lapic.

x86: Clean up lapic codes

2015-07-15T00:03:16+00:00

This commit cleans up the lapic codes:
- Delete arch/x86/include/asm/lapic_def.h, and move register and bit
  defines into arch/x86/include/asm/lapic.h
- Use MSR defines from msr-index.h in enable_lapic() and disable_lapic()
- Remove unnecessary stuff like NEED_LAPIC, X86_GOOD_APIC and
  CONFIG_AP_IN_SIPI_WAIT
- Move struct x86_cpu_priv defines to asm/arch-ivybridge/bd82x6x.h, as
  it is not apic related and only used by ivybridge
- Fix coding convention issues
