Giffuni pfg@FreeBSD.org 2017-11-27T14:52:40Z urn:sha1:718cf2ccb9956613756ab15d7a0e28f2c8e91cab 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. Add support for the uart classes to set their default register shift value. 2015-04-11T17:16:23Z Andrew Turner andrew@FreeBSD.org 2015-04-11T17:16:23Z urn:sha1:405ada37fbdafaa6691a906f3630ba8d064e5f30 This is needed with the pl011 driver. Before this change it would default to a shift of 0, however the hardware places the registers at 4-byte addresses meaning the value should be 2. This patch fixes this for the pl011 when configured using the fdt. The other drivers have a default value of 0 to keep this a no-op.

These functions should turn off the RX interrupts, and any others that interfere. This makes mountroot prompt work again. If there's more generalized need other than prompting, many of these routines should be expanded to do those new things. Should have been part of r260889, but waasn't due to command line typo.
