3cabcf966d x86: Move acpi_s3.h to include/acpi/
This header relates to ACPI and we are about to add some more ACPI
headers. Move this one into a new directory so they are together.

The header inclusion in pci_rom.c is not specific to x86 anymore, so drop
the #ifdef CONFIG_X86.

515e8174f5 x86: Update mrccache to support multiple caches
With Apollo Lake we need to support a normal cache, which almost never
changes and a much smaller 'variable' cache which changes every time.

Update the code to add a cache type, use an array for the caches and use a
for loop to iterate over the caches.

8331188615 x86: Rename existing FSP code to fsp1
Since there is now a new version of the FSP and it is incompatible with
the existing version, move the code into an fsp1 directory. This will
allow us to put FSP v2 code into an fsp2 directory.

Add a Kconfig which defines which version is in use.

Some of the code in this new fsp1/ directory is generic across both FSPv1
and FSPv2. Future patches will address this.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

fb2c53091f Revert "x86: fsp: Configure SPI opcode registers before SPI is locked down"
This reverts commit 1e6ebee667.

It's not appropriate to call the Intel SPI driver specific stuff in
the FSP codes. We may add a simple DTS property "intel,spi-lock-down"
and let the Intel SPI driver call these stuff instead.

1e6ebee667 x86: fsp: Configure SPI opcode registers before SPI is locked down
Some Intel FSP (like Braswell) does SPI lock-down during the call
to fsp_notify(INIT_PHASE_BOOT). But before SPI lock-down is done,
it's bootloader's responsibility to configure the SPI controller's
opcode registers properly otherwise SPI controller driver doesn't
know how to communicate with the SPI flash device.

This introduces a Kconfig option CONFIG_FSP_LOCKDOWN_SPI for such
FSPs. When it is on, U-Boot will configure the SPI opcode registers
before the lock-down.

76d1d02fd2 board_f: x86: Use checkcpu() for CPU init
At present we misuse print_cpuinfo() do so CPU init on x86. This is done
because it is the next available call after the console is enabled. But
several arches use checkcpu() instead. Despite the horrible name (which
we can fix), it seems a better choice.

Adjust the various x86 CPU implementations to move their init code into
checkcpu() and use print_cpuinfo() only for printing CPU info.

While x86 is the only user and this could in principle be moved to
arch_cpu_init() there is some justification for this being a separate
call. It provides a way to handle init which is not CPU-specific, but
must happen before the CPU can be set up.

Rename the function to be more generic.

aefaff8ed8 x86: fsp: Move FspInitEntry call to board_init_f()
The call to FspInitEntry is done in arch/x86/lib/fsp/fsp_car.S so far.
It worked pretty well but looks not that good. Apart from doing too
much work than just enabling CAR, it cannot read the configuration
data from device tree at that time. Now we want to move it a little
bit later as part of init_sequence_f[] being called by board_init_f().
This way it looks and works better in the U-Boot initialization path.

Due to FSP's design, after calling FspInitEntry it will not return to
its caller, instead it jumps to a continuation function which is given
by bootloader with a new stack in system memory. The original stack in
the CAR is gone, but its content is perserved by FSP and described by
a bootloader temporary memory HOB. Technically we can recover anything
we had before in the previous stack, but that is way too complicated.
To make life much easier, in the FSP continuation routine we just
simply call fsp_init_done() and jump back to car_init_ret() to redo
the whole board_init_f() initialization, but this time with a non-zero
HOB list pointer saved in U-Boot's global data so that we can bypass
the FspInitEntry for the second time.
