45f41c134b ARM: uniphier: add weird workaround code for LD20
When booting from ARM Trusted Firmware, U-Boot runs in EL1-NS.
The boot flow is as follows:
  BL1 -> BL2 -> BL31 -> BL33 (i.e. U-Boot)

This boot sequence works fine for LD11 SoC (Cortex-A53), but LD20
SoC (Cortex-A72) hangs in U-Boot.  The solution I found is to
read sctlr_el1 and write back the value as-is.  This should be
no effect, but surprisingly fixes the problem for LD20 to boot.
I do not know why.

Remove 'pad-offset' of soc_gpio_s5_0, soc_gpio_s5_1, soc_gpio_s5_2,
pin_usb_host_en0 and pin_usb_host_en1. These offsets are actually
wrong. Correct value should be added by 0x2000, but since they
are supposed to be 'mode-gpio', 'pad-offset' is not needed at all.

770ee01742 x86: ich6_gpio: Add use-lvl-write-cache for I/O access mode
Add a device-tree property use-lvl-write-cache that will cause
writes to lvl to be cached instead of read from lvl before each
write. This is required on some platforms that have the register
implemented as dual read/write (such as Baytrail).

Prior to this fix the blue USB port on the Minnowboard Max was
unusable since USB_HOST_EN0 was set high then immediately set
low when USB_HOST_EN1 was written.

This also resolves the 'gpio clear | set' command warning like:
  "Warning: value of pin is still 0"

5ae5aa9310 x86: acpi: Fix Windows S3 resume failure
U-Boot sets up the real mode interrupt handler stubs starting from
address 0x1000. In most cases, the first 640K (0x00000 - 0x9ffff)
system memory is reported as system RAM in E820 table to the OS.
(see install_e820_map() implementation for each platform). So OS
can use these memories whatever it wants.

If U-Boot is in an S3 resume path, care must be taken not to corrupt
these memorie otherwise OS data gets lost. Testing shows that, on
Microsoft Windows 10 on Intel Baytrail its wake up vector happens to
be installed at the same address 0x1000. While on Linux its wake up
vector does not overlap this memory range, but after resume kernel
checks low memory range per config option CONFIG_X86_RESERVE_LOW
which is 64K by default to see whether a memory corruption occurs
during the suspend/resume (it's harmless, but warnings are shown
in the kernel dmesg logs).

We cannot simply mark the these memory as reserved in E820 table
because such configuration makes GRUB complain: unable to allocate
real mode page. Hence we choose to back up these memories to the
place where we reserved on our stack for our S3 resume work.
Before jumping to OS wake up vector, we need restore the original
content there.

To do something more in acpi_resume() like turning on ACPI mode,

is done in acpi_find_wakeup_vector().

This changes acpi_resume() signature to accept ACPI FADT pointer
as the parameter. A new API acpi_find_fadt() is introduced, and
acpi_find_wakeup_vector() is updated to use FADT pointer as the
parameter as well.
