[PATCH v4 0/5] net: phy: aquantia: Switch to generic firmware loader

[Beiyan Yun]

Hi,

This patch series refactors the Aquantia PHY firmware loader to use
the generic fsloader framework.

The existing loader is limited to loading firmware from an MMC device,
which restricts its use on many devices (e.g., routers) that may use
other storage like USB or have a UBIFS root filesystem. Migrating to the
generic firmware loader allows firmware to be sourced from any backend
supported by the fwloader and fsloader framework.

The series is structured as follows:
- The first patch is formatting.
- The second patch aligns binding document with upstream and prepares
  for the migration.
- The third patch aligns binding for MDI with upstream.
- The fourth patch prepares current loading code for fsloader.
- The final and main patch replaces the custom loader with generic one.

Kept smb-addr intact as NXP is the only consumer.

This change has been tested on a Buffalo WXR18000BE10P router, loading
firmware from a UBIFS volume for Marvell CUX3410.

Changes in v4:
- net: phy: aquantia: refresh format
- net: phy: aquantia: refactor firmware upload helpers
- Split firmware upload helpers change
- Reorder `aquantia_read_fw`
- Make `aquantia_read_fw` weak to allow overide
- Rename exit label in `aquantia_read_fw`
- Kconfig polish

Changes in v3:
- Select FW_LOADER with PHY_AQUANTIA_UPLOAD_FW

Changes in v2:
- doc: bindings: use upstream bindings for aquantia phy
- net: phy: aquantia: replace the "mdi-reversal" node with "marvell,mdi-cfg-order"
- Add support for script based loader
