0ff4c01b27 ARM: SoC 64-bit changes
Changes to platform code for 64-bit ARM platforms.
 
 Most of these are small changes to the one defconfig we use on arm64
 (no per-platform configs there), to enable new drivers.
 
 There are also a few other changes. Broadcom sold off their 'Vulcan'
 design to Cavium, where it is now called ThunderX2. While we normally
 don't rename stuff based on marketing's whims, it seemed appropriate to
 bring in renames on a few things such as MAINTAINERS, etc.

trigger - this was not required before because the gpio-leds driver has

5d3d9c8bda crypto: arm64/crc32 - merge CRC32 and PMULL instruction based drivers
The PMULL based CRC32 implementation already contains code based on the
separate, optional CRC32 instructions to fallback to when operating on
small quantities of data. We can expose these routines directly on systems
that lack the 64x64 PMULL instructions but do implement the CRC32 ones,
which makes the driver that is based solely on those CRC32 instructions
redundant. So remove it.

Note that this aligns arm64 with ARM, whose accelerated CRC32 driver
also combines the CRC32 extension based and the PMULL based versions.

3bd776bbda ARM: SoC 64-bit changes for v4.9
Changes to platform code for 64-bit ARM platforms. We are not adding
 any new platforms that require code or Kconfig changes this time, so
 it's basically just defconfig changes to enable support for more
 drivers used on the existing platforms.
 
 This is mainly interesting for the Raspberry Pi 3, which should
 now work much better with the default build.
