Remove xscale support.

2018-07-27T21:25:07+00:00

As discussed in arm@.  This is a scaled back version of the prior
commit because xscale is overlaoded in places to mean armv5 or
similar.  The OLD XSCALE stuff hasn't been useful in a while. The
original committer (cognet@) was the only one that had boards for
it. He's blessed this removal. Newer XSCALE (GUMSTIX) is for hardware
that's quite old. After discussion on arm@, it was clear there was no
support for keeping it.

Revert r336773: it removed too much.

2018-07-27T21:25:01+00:00

r336773 removed all things xscale. However, some things xscale are
really armv5. Revert that entirely. A more modest removal will follow.

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

2017-11-27T15:04:10+00:00

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.

Allow setting access-width for UART registers.

2017-02-27T20:08:42+00:00

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.
