For boards that don't route serial port pins out, it's quite common
to attach a USB keyboard as the input device, along with a monitor.
However USB is not automatically started in the generic efi payload
codes. This uses a payload specific last_stage_init() to start the
USB bus, so that a USB keyboard can be used on the U-Boot shell.

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

just oops, while sometimes kernel throws MCE errors and hangs:

mce: [Hardware Error]: CPU 0: Machine Check: 0 Bank 4: c400000000010151

mce: [Hardware Error]: PROCESSOR 0:406c3 TIME 1508160686 SOCKET 0 APIC 0 microcode 363
This looks like a hardware error per mcelog. After debugging, it
seems turning off turbo mode on the processor does not expose this
behavior, although U-Boot runs OK with turbo mode on. Suspect it is
related to an errata of Braswell processor.
To fix this, remove the Braswell cpu driver which does the turbo
mode configuration, and switch to use the generic cpu-x86 driver.
Also there is a configuration option in the FSP that turns on the
turbo mode and that has been turned off too.

It was observed that when booting a Ubuntu 16.04 kernel, doing ACPI
S3 suspend/resume sometimes causes the Ubuntu kernel hang forever.
The issue is however not reproduced with a kernel built from i386/
x86_64 defconfig configuration.
The unstability is actually caused by unexpected interrupts being
generated during the S3 resume. For some unknown reason, FSP (gold4)
for BayTrail configures the GPIO DFX5 PAD to enable level interrupt
(bit 24 and 25). As this pin keeps generating interrupts during an
S3 resume, and there is no IRQ requester in the kernel to handle it,
the kernel seems to hang and does not continue resuming.
Clear the mysterious interrupt bits for this pin.
