[PATCH] docs: Add a basic security document

[Tom Rini]

Based loosely on the Linux kernel
Documentation/admin-guide/security-bugs.rst file, create a basic
security document for U-Boot.  In sum, security issues should be
disclosed in public on the mailing list if at all possible as an initial
position.

+Handling of security vulnerabilities
+====================================
+
+The U-Boot project takes security very seriously.  As such, we'd like to know
+when a security bug is found so that it can be fixed and disclosed as quickly
+as possible.
+
+Contact
+-------
+
+The preferred initial point of contact is to send email to
+`u-boot at lists.denx.de` and use `scripts/get_maintainers.pl` to also include any
+relevant custodians. In addition, Tom Rini should be contacted at
+`trini at konsulko.com`.
+
+CVE assignment
+--------------
+
+The U-Boot project cannot directly assign CVEs, nor do we require them for
+reports or fixes, as this can needlessly complicate the process and may delay
+the bug handling. If a reporter wishes to have a CVE identifier assigned ahead
+of public disclosure, they will need to coordinate this on their own.  When
+such a CVE identifier is known before a patch is provided, it is desirable to
+mention it in the commit message if the reporter agrees.
+
+Non-disclosure agreements
+-------------------------
+
+The U-Boot project is not a formal body and therefore unable to enter any
+non-disclosure agreements.
