[PATCH 00/19] ARM: mvebu: add Netgear RN102/RN104 support and related drivers

[Luca Lauro via B4 Relay]

This series adds full barebox support for the Netgear RN102 and RN104
NAS platforms based on the Marvell Armada 370 SoC. Both devices share
the same hardware architecture, with differences mainly in the number
of drive bays and the associated board-level integration.

The series introduces:
 - lowlevel initialization code for RN102 and RN104
 - board support files and environment integration
 - barebox-specific device trees for both platforms
 - image generation support and defconfig updates
 - fan controller framework and G76x driver
 - fan control command and Kconfig/Makefile integration
 - Marvell-specific EHCI host controller driver
 - AHCI/SATA fixes improving compatibility with Armada 370
 - USB/AHCI integration updates

The goal is to provide complete bootloader support for these NAS
devices, enabling reliable initialization of storage, USB, fan control,
and board-specific peripherals. The patches have been tested on
RN102 only.
