The GEM is instantiated with a different setup than the\nones in the Atmel family, and this patchset allows the driver to run\non this other configuration, with no significant change of behavior\non already supported platforms. (The support of the SoC itself will\nnot reach the mailing-list before months).\n\nThis patchset was tested on emulator, with a RGMII fixed-link, by\npinging a remote host (an actual computer, connected to the emulator\nand running Linux). The test produced an ARP request/answer followed\nby a successful ICMP request/answer, using the legacy IP stack in\nu-boot.\n\nThe patchset was developed and tested on top of U-boot v2026.1\n\nIt was not tested for non-regression on previous hardware, since I do\nnot own any.\n\nThis patchset\n* Remove a build issue when the mach does not have its own clk.h\n* Uses MAC filter 1 instead of 3, for GEMs without 3 filters\n* Does not set the user_io register on GEMs that do not have one\n* Add fixed-link for Gigabit (added for test purpose, may be dropped)\n\nThanks,\nChristian\n\nSigned-off-by: Christian DREHER \n---\nChristian DREHER (4):\n net: macb: include arch/clk.h only when necessary\n net: macb: use SA1 for MAC filtering on GEM\n net: macb: do not set user_io when it does not exist\n net: macb: add gigabit implementation for fixed-link\n\n drivers/net/macb.c | 94 ++++++++++++++++++++++++++++++++++++++++--------------\n drivers/net/macb.h | 2 ++\n 2 files changed, 72 insertions(+), 24 deletions(-)\n---\nbase-commit: 4433253ecf2041f9362a763bb6cb79960921ac7e\nchange-id: 20260428-net-macb-support-for-feature-lite-instances-fb0707bbad26\n\nBest regards,\n-- \nChristian DREHER "}
