[U-Boot] [PATCH v2 0/6] Extend mv88e61xx driver to support 88E6071

This series adds support for 88E6071 switches in the mv88e61xx driver.
Changes in v2: - fix port init for 6096/6097 devices in patch 1/6 - update commit description in patch 4/6

Extend the driver to init switch register offsets from variables instead of compile time macros and enable 88E6071 detection. Ethernet transfer (e.g. tftp) does not work yet, so enable the registration of the 'indirect mii' bus for easier PHY register access by 'mii' command.

On 88E6071 chip the port status register bit field offsets for duplex and link bits differ. Extend the driver to use 88E6071 specific offset values. The width of bit fields for speed status differ, too. Adapt for proper port speed detection on 88E6071.

On mv88E6071 the 'EDet' field offset, width and sense control bits are different, adjust the driver to init the PHY control register as needed. This fixes not working link detection and tftp transfers.

Good grief... kind of obnoxious how much is changed seemingly arbitrarily. Hmm. Not friendly to software.

We want to be able to use single U-Boot images which support different switches, a choice will make it not possible.

I don't see how choice is any different than what you have here in that respect. You have a hard-coded selection among families. If you have a need to run the same binary on multiple switches, then this option should be removed and the pre-init should be detecting the target.
