[PATCH v2 00/10] ARM: mvebu: add Netgear RN102/RN104 support and related drivers

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.

Changes in v2:

Hi Sascha,

thanks for the review of the v1 series.

This v2 reorganizes the series to make it clearer and easier to review.
Platform‑specific patches have been grouped into thematic commits, noisy
changes should have been removed, and commit messages have been rewritten 
to better describe the functional modifications.

The AHCI patch has been cleaned up and clarified, the EHCI patches now
contain only functional changes, and the fan framework integration has
been consolidated. The previous “USB/AHCI integration” patch has been
squashed into the relevant commits.

No functional changes have been introduced beyond what was already
present in v1.

Thanks again for your feedback,
Luca Lauro
