[RFC PATCH 00/13] Add support for Allwinner R329

This patchset adds Allwinner R329 support to U-Boot.

First, some code refactors happen for SoCs w/o SCP/MMC2.

Then the basical support for R329 come as several parts (memory map,
clocks, pinmux, DRAM, final Kconfig option).

Then, as the RFC part of this patchset, some device tree related
changes.

Finally it comes the defconfig file for a R329 board, Sipeed Maix IIA
Dock.

This patchset is RFC mainly because of the DT-related part, as no DT
binding is mainlined in Linux now (it's still WIP). All other patches
are ready for being reviewed and, if proper, merged.

Icenowy Zheng (13):
  sunxi: decide the inclusion of SCP by SCP_ADDR existence
  sunxi: only include alias for eMMC when mmc2 used
  mmc: sunxi: conditionally include MMC2 initialization code
  sunxi: add memory addresses for R329 SoC
  sunxi: add support for R329 clocks
  sunxi: add support for basical pinmux setup on R329
  sunxi: add support for R329 DRAM controller
  sunxi: add Kconfig option for R329
  sunxi: sync R329 CCU binding headers from internal WIP kernel tree
  clk: sunxi: add support for R329 in sunxi DM clock driver
  mmc: sunxi: add support for R329 MMC controller
  sunxi: sync R329 DTs from internal WIP kernel tree
  sunxi: add support for Sipeed Maix IIA Dock board
