The branch main has been updated by adrian: URL: https://cgit.FreeBSD.org/src/commit/?id=02438ce5fd1892e3f59e4f1e83a0ac810396853f commit 02438ce5fd1892e3f59e4f1e83a0ac810396853f Author: Adrian Chadd <adrian@FreeBSD.org> AuthorDate: 2021-10-16 18:47:44 +0000 Commit: Adrian Chadd <adrian@FreeBSD.org> CommitDate: 2021-10-18 19:19:00 +0000 ipq4018: add initial IPQ4018/IPQ4019 support This is for the Qualcomm Atheros quad-core ARMv7 SoC with built-in 2x2 2GHz and 5GHz ath10k devices. It's enough (with an upcoming set of config files) to netboot on an ASUS router I have here and get to a single core mountroot prompt. --- sys/arm/qualcomm/ipq4018_machdep.c | 194 +++++++++++++++++++++++++++++++++++++ sys/arm/qualcomm/ipq4018_machdep.h | 38 ++++++++ sys/arm/qualcomm/ipq4018_mp.c | 61 ++++++++++++ sys/arm/qualcomm/ipq4018_reg.h | 42 ++++++++ sys/arm/qualcomm/std.ipq4018 | 2 + 5 files changed, 337 insertions(+) diff --git a/sys/arm/qualcomm/ipq4018_machdep.c b/sys/arm/qualcomm/ipq4018_machdep.c new file mode 100644 index 000000000000..b3f841575ebb --- /dev/null +++ b/sys/arm/qualcomm/ipq4018_machdep.c @@ -0,0 +1,194 @@ +/*- + * SPDX-License-Identifier: BSD-2-Clause-FreeBSD + * + * Copyright (c) 2021 Adrian Chadd <adrian@FreeBSD.org> + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
