Research direction

Search the iMXRT Ethernet source for imxrt_determine_phy() and imxrt_phyintenable(), and find where BOARD_ETH0_PHY_LIST and the CONFIG_ETH0_YT8512 and CONFIG_ETH0_PHY_YT8512 options are used. Confirm that the scan result is never saved and that the config name in the check does not match the Kconfig symbol. Done when the found PHY address is stored for use and the YT8512 check uses the Kconfig name, and the iMXRT build still compiles.

Description / Steps to reproduce the issue

Two smaller upstream issues I noticed but left alone:

  • PHY address scan: imxrt_determine_phy() never stores the PHY address it finds,
    so address ranges in BOARD_ETH0_PHY_LIST don't work. The EC300 isn't affected
    because it uses a single address.
  • YT8512 config name: imxrt_phyintenable() checks CONFIG_ETH0_YT8512, but the
    Kconfig option is CONFIG_ETH0_PHY_YT8512.
