Remove kernel support for armeb

2018-07-17T23:23:45Z

Remove all the big-endian arm architectures (ixp425 and ixp435) support in the kernel and associated drivers. Differential Revision: https://reviews.freebsd.org/D16257

sys/dev: further adoption of SPDX licensing ID tags.

2017-11-27T14:52:40Z

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.

Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.

Provide a workaround for setting the correct endianness when doing CFI on

a mips big-endian board. This is (hopefully! ish!) a temporary change until a slightly better way can be found to express this without a config option. Tested: * BUFFALO WZR-HP-G300NH 1stGen (by submitter) Submitted by: Mori Hiroki

Follow up to r225617. In order to maximize the re-usability of kernel code

2014-10-16T18:04:43Z

in userland rename in-kernel getenv()/setenv() to kern_setenv()/kern_getenv(). This fixes a namespace collision with libc symbols. Submitted by: kmacy Tested by: make universe

Follow r261352 by updating all drivers which are children of simplebus

2014-02-02T19:17:28Z

to check the status property in their probe routines. Simplebus used to only instantiate its children whose status="okay" but that was improper behavior, fixed in r261352. Now that it doesn't check anymore and probes all its children; the children all have to do the check because really only the children know how to properly interpret their status property strings. Right now all existing drivers only understand "okay" versus something- that's-not-okay, so they all use the new ofw_bus_status_okay() helper.

Set BUS_PROBE_NOWILDCARD on this attachment as a stopgap. Unconditionally

2013-10-22T14:10:00Z

poking at registers in unknown devices is not the best probe mechanism. This should be reverted and a better solution found later.

MFP4: 1136252

2013-10-18T20:52:42Z

Add an option ATSE_CFI_HACK to allow memory mapped CFI devices to have their address range allocated sharable so that atse(4) can find it's Ethernet address in the expected location. We intend to remove this hack once the BERI platform has a loader.
