Pull ARM updates from Russell King:
 "The major updates included in this update are:

   - Clang compatible stack pointer accesses by Behan Webster.
   - SA11x0 updates from Dmitry Eremin-Solenikov.
   - kgdb handling of breakpoints with read-only text/modules
   - Support for Privileged-no-execute feature on ARMv7 to prevent
     userspace code execution by the kernel.
   - AMBA primecell bus handling of irq-safe runtime PM
   - Unwinding support for memset/memzero/memmove/memcpy functions
   - VFP fixes for Krait CPUs and improvements in detecting the VFP
     architecture
   - A number of code cleanups (using pr_*, removing or reducing the
     severity of a couple of kernel messages, splitting ftrace asm code
     out to a separate file, etc.)
   - Add machine name to stack dump output"

generic fixmaps
ARM support for CONFIG_DEBUG_RODATA

This patch extends the firmware_ops structure with two new callbacks:
.suspend() and .resume(). The former is intended to ask the firmware to
save all its volatile state and suspend the system, without returning
back to the kernel in between. The latter is to be called early by
very low level platform suspend code after waking up to restore low
level hardware state, which can't be restored in non-secure mode.

While at it, outdated version of the structure is removed from the
documentation and replaced with a reference to the header file.

Lately we have received documentation for A31 and A31s, in addition to

Add these to the README, and update to reflect that A31 and A23 are
supported.

With commit a05e54c103b0 ("ARM: 8031/2: change fixmap mapping region to
support 32 CPUs"), the fixmap region was expanded to 2MB, but it
precluded any other uses of the fixmap region. In order to support other
uses the fixmap region needs to be expanded beyond 2MB. Fortunately, the
adjacent 1MB range 0xffe00000-0xfff00000 is availabe.

Remove fixmap_page_table ptr and lookup the page table via the virtual
address so that the fixmap region can span more that one pmd. The 2nd
pmd is already created since it is shared with the vector page.

Pull ARM SoC DT updates from Arnd Bergmann:
 "As usual, this is the largest branch, though this time a little under
  half of the total changes with 307 individual non-merge changesets.

  The largest changes are the addition of new machines, in particular
  the Tegra based Chromebook, the Renesas r8a7794 SoC, and DT support
  for the old i.MX1 platform.

  Other changes include
   - at91: various sam9 and sama5 updates
   - exynos: much extended Peach Pi/Pit (Chromebook 2) support
   - keystone: new peripherals
   - meson: added DT for meson6 SoC
