Rewrite README in markdown

This will make it render more nicely if linux-firmware.git moves
to Gitlab or a fork of it is hosted in Gitlab.

+# Linux firmware
+
+This repository contains all these firmware images which have been
+extracted from older drivers, as well various new firmware images which
+we were never permitted to include in a GPL'd work, but which we _have_
+been permitted to redistribute under separate cover.
+
+The upstream repository is located at <https://gitlab.com/kernel-firmware/linux-firmware.git>.
+
+## Submitting firmware
+
+To submit firmware to this repository, please do one of the following:
+
+* open a MR [upstream](https://gitlab.com/kernel-firmware/linux-firmware)
+* send a git binary diff to `linux-firmware@kernel.org`
+* send a git pull request to: `linux-firmware@kernel.org`
+
+## Quality
+
+If your commit adds new firmware, it must update the `WHENCE` file to
+clearly state the license under which the firmware is available, and
+that it is redistributable. Being redistributable includes ensuring
+the firmware license provided includes an implicit or explicit
+patent grant to end users to ensure full functionality of device
+operation with the firmware. If the license is long and involved, it's
+permitted to include it in a separate file and refer to it from the
+`WHENCE` file (IE _'See `LICENSE.foo` for details.'_).
+And if it were possible, a changelog of the firmware itself.
+
+To maintain consistent quality on the repository, please run the following
+before submitting a patch:
+
+```shell
+make check
+```
+
+If you don't have pre-commit installed, you can install it with:
+
+```shell
+pip install pre-commit
+```
+
+Your commit **must** contain a `Signed-Off-By:` from someone authoritative on
+the licensing of the firmware in question (i.e. from within the company
+that owns the code).
+
+## Warnings
+
+1. Don't send any `CONFIDENTIALITY STATEMENT` in your e-mail, patch or
+request. Otherwise your firmware _will never be accepted_.
+2. Maintainers are really busy, so don't expect a prompt reply.
