* spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSDWarner Losh2023-07-251-1/+1
| | | | | | | | | | | The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch up to that fact and revert to their recommended match of BSD-2-Clause. Discussed with: pfg MFC After: 3 days Sponsored by: Netflix (cherry picked from commit 4d846d260e2b9a3d4d0a701462568268cbfe7a5b)
* add snps IP uart support / genaralize UARTMatt Macy2018-08-191-1/+1
| | | | | | | | | | | | | | | | This is an amalgam of a patch by Doug Ambrisko to generalize uart_acpi_find_device, imp moving the ACPI table to uart_dev_ns8250.c and advice by jhb to work around a bug in the EPYC 3151 BIOS (the BIOS incorrectly marks the serial ports as disabled) Reviewed by: imp MFC after: 8 weeks Differential Revision: https://reviews.freebsd.org/D16432 Notes: svn path=/head/; revision=338074
* sys/mips: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326259
* Allow setting access-width for UART registers.Ruslan Bukin2017-02-271-1/+1
| | | | | | | | | | | | | | | This is required for FDT's standard "reg-io-width" property (similar to "reg-shift" property) found in many DTS files. This fixes operation on Altera Arria 10 SOC Development Kit, where standard ns8250 uart allows 4-byte access only.

* Rather than shifting offsets by three, set register offset to 3. All ourJuli Mallett2010-10-021-4/+3
| | | | | | | | | | | | bus interface does that's special here now is to use a 64-bit register size. In theory, uart(4) ought to support a regsz as well as regshft and support 64-bit registers directly. Also use the UART class's range rather than a hand-coded 1024 for the address range.

* Update the port of FreeBSD to Cavium Octeon to use the Cavium Simple ExecutiveJuli Mallett2010-07-201-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | library: o) Increase inline unit / large function growth limits for MIPS to accommodate the needs of the Simple Executive, which uses a shocking amount of inlining. o) Remove TARGET_OCTEON and use CPU_CNMIPS to do things required by cnMIPS and the Octeon SoC. o) Add OCTEON_VENDOR_LANNER to use Lanner's allocation of vendor-specific board numbers, specifically to support the MR320. o) Add OCTEON_BOARD_CAPK_0100ND to hard-wire configuration for the CAPK-0100nd, which improperly uses an evaluation board's board number and breaks board detection at runtime. This board is sold by Portwell as the CAM-0100. o) Add support for the RTC available on some Octeon boards. o) Add support for the Octeon PCI bus. Note that rman_[sg]et_virtual for IO ports can not work unless building for n64. o) Clean up the CompactFlash driver to use Simple Executive macros and structures where possible (it would be advisable to use the Simple Executive API to set the PIO mode, too, but that is not done presently.) Also use structures from FreeBSD's ATA layer rather than structures copied from Linux. o) Print available Octeon SoC features on boot. o) Add support for the Octeon timecounter. o) Use the Simple Executive's routines rather than local copies for doing reads and writes to 64-bit addresses and use its macros for various device addresses rather than using local copies. o) Rename octeon_board_real to octeon_is_simulation to reduce differences with Cavium-provided code originally written for Linux. Also make it use the same simplified test that the Simple Executive and Linux both use rather than our complex one. o) Add support for the Octeon CIU, which is the main interrupt unit, as a bus to use normal interrupt allocation and setup routines. o) Use the Simple Executive's bootmem facility to allocate physical memory for the kernel, rather than assuming we know which addresses we can steal. NB: This may reduce the amount of RAM the kernel reports you as having if you are leaving large temporary allocations made by U-Boot allocated when starting FreeBSD. o) Add a port of the Cavium-provided Ethernet driver for Linux. This changes Ethernet interface naming from rgmxN to octeN. The new driver has vast improvements over the old one, both in performance and functionality, but does still have some features which have not been ported entirely and there may be unimplemented code that can be hit in everyday use. I will make every effort to correct those as they are reported. o) Support loading the kernel on non-contiguous cores. o) Add very conservative support for harvesting randomness from the Octeon random number device. o) Turn SMP on by default. o) Clean up the style of the Octeon kernel configurations a little and make them compile with -march=octeon. o) Add support for the Lanner MR320 and the CAPK-0100nd to the Simple Executive. o) Modify the Simple Executive to build on FreeBSD and to build without executive-config.h or cvmx-config.h. In the future we may want to revert part of these changes and supply executive-config.h and cvmx-config.h and access to the options contained in those files via kernel configuration files. o) Modify the Simple Executive USB routines to support getting and setting of the USB PID.

* Merge from projects/mips to head by hand:Warner Losh2010-01-091-0/+121
Copy the support files for the Octeon 1 CPU from sys/mips/octeon1 on the projects/mips side to sys/mips/cavium on the head side to conform to the other vendor code. This code was contributed by Cavium to the project and forward ported by Warner Losh, with some additional code from Randal Stewart. # I'll fix the building problems the move creates in a future commit.
