[PATCH v4 0/5] arm: mvebu: Support for 98DX25xx/98DX35xx (AlleyCat5)

[Chris Packham]

These patches are based on Marvell's bootloader for the AlleyCat5/5X
which was based on u-boot 2018.03. I've split that code into consumable
chunks and dropped as much unnecessary stuff as I can. I've also tried
to sync the device trees as much as possible with the support that will
land in Linux 6.0 although there are still some differences

Changes in v4:
- Collect r-by from Stefan
- Remove unused mvebu_get_nand_clock() (will return in a later series)
- Remove unnecessary #ifdefs
- Misc style cleanups
- Replace CONFIG_MVEBU_SAR with simpler code implemented directly in
  soc.c based around get_sar_freq which the 32-bit platforms already
  use.
- Move CONFIG_DISPLAY_BOARDINFO_LATE and CONFIG_ENV_OVERWRITE to
  the defconfig.
- Remove CONFIG_BAUDRATE as this is already set in the default config
- Remove CONFIG_USB_MAX_CONTROLLER_COUNT as this is not needed with
  DM_USB
- Remove CONFIG_PREBOOT as we don't have anything to run
- Remove commented out CONFIG_BOARD_EARLY_INIT_R
- Remove DEBUG_UART configuration
- Remove unnecessary console environment variable
- Remove CONFIG_MVEBU_SAR

Changes in v3:
- Remove unnecessary changes to RX descriptor handling
- Use dev_get_dma_range() to parse dma-ranges property from parent
  device.
- Remove unnecessary dma-ranges property from ethernet nodes (mvneta now
  correctly parses the property from the parent node).
- Keep soc_print_clock_info and soc_print_device_info local to
  alleycat5.
- Remove MMC and UBIFS distroboot options (MMC driver is not currently
  functional, NAND is not populated on the RD-AC5X board)
- Remove unnecessary Ethernet configuration
- Remove unnecessary NAND configuration
- Remove memory node from dts so the value passed by the DDR FW will be
  used

Changes in v2:
- Use distro boot by default
- remove unnecessary SPI-NOR partitions
