Pull ARM SoC platform updates from Olof Johansson:
 "SoC platform changes (arch/arm/mach-*). This merge window, the bulk is
  for a few platforms:

  Gemini:
   - Legacy platform that Linus Walleij has converted to multiplatform
     and DT, so a handful of various tweaks there, removal of some old
     stale support, etc.

  Atmel AT91:
   - Fixup of various power management related pieces
   - Move of SoC detection to a drivers/soc driver instead

  ST Micro STM32:
   - New SoC support: STM32H743

  TI platforms:
   - More driver support for Davinci (SATA in particular)
   - Removal of some old stale hwmod files (linkspace platform)

  Misc:
   - A couple of smaller patches for i.MX, sunxi, hisi"

+	- 2MB internal flash, 1MBytes internal RAM
+	- FMC controller to connect SDRAM, NOR and NAND memories
+	- Dual mode QSPI
+	- SD/MMC/SDIO support
+	- Ethernet controller
+	- USB OTFG FS & HS controllers
+	- I2C, SPI, CAN busses support
+	- Several 16 & 32 bits general purpose timers
+	- Serial Audio interface
+	- LCD controller
+	- HDMI-CEC
+	- SPDIFRX
+	- DFSDM
+
+  Resources
+  ---------
+	Datasheet and reference manual are publicly available on ST website:
