Betreff: [U-Boot, v1, 1/1] net: phy: Add the Airoha EN8811H PHY driver
Add the driver for the Airoha EN8811H 2.5 Gigabit PHY. The PHY supports
100/1000/2500 Mbps with auto negotiation only.
The driver uses two firmware files, for which updated versions are added to
linux-firmware already.
Locating the AIROHA FW within the filesystem at the designated partition
and path will trigger its automatic loading and writing to the PHY via MDIO.
If need board specific loading override,
please override the en8811h_read_fw function on board or architecture level.
Linux upstream AIROHA EN8811H driver commit:
71e79430117d56c409c5ea485a263bc0d8083390
Based on the Linux upstream AIROHA EN8811H driver code(air_en8811h.c),
I have modified the relevant process to align with the U-Boot boot sequence.
and have validated this on Banana Pi BPI-R3 Mini.

Hi,
is there any progress? i see no review or apply (+tom in To-header).
I'm not super thrilled at the concept of having to load firmware from a
filesystem. But since we have to do this anyways in other cases, is this
something we could be using FS_LOADER for or no?
The filesystem loading was requested in mailinglist.
Original version loaded firmware from emmc boot1 partition (current openwrt
driver version) or c header file generated from the binaries (my version). I do
not know FS_LOADER yet,but if this a more generic way to load firmware file it
could be a way. Lucien,what do you think?
regards Frank
I'm not very familiar with the FS_LOADER part of U-Boot, so I'll need to look
into that.
However, based on previous mailing list discussions, it was suggested that I
refer to the Aquatia PHY and its method of loading the PHY firmware from the
filesystem on a block device.
Additionally, the recommendation was to implement a __weak default loading from
a file on the filesystem by default.
This way, if a specific platform needs to replace its loading method, it can
simply be overridden at the board or architecture level.
Thanks
Lucien Jheng
