v9 -> v10

* Update commit message to include the changelog before the SoB tag(s).

v8 -> v9

* No changes.

v7 -> v8

* No changes.

  supported, with Arm to come afterwards. The NE kernel driver can be
  built for aarch64 arch.

v5 -> v6

* No changes.

v4 -> v5

* Add arch dependency for Arm / x86.

v3 -> v4

* Add PCI and SMP dependencies.

v2 -> v3

* Remove the GPL additional wording as SPDX-License-Identifier is

  directory.
* Update help in Kconfig.
