From 78a88f7930becb78afef09c1237a8e4edc1b01e1 Mon Sep 17 00:00:00 2001 From: Mario Six Date: Tue, 10 Jul 2018 08:40:17 +0200 Subject: doc: Replace DocBook with sphinx-based docs The Linux kernel moved to sphinx-based documentation and got rid of the DocBook based documentation quite a while ago. Hence, the DocBook documentation for U-Boot should be converted as well. To achieve this, import the necessary files from Linux v4.17, and convert the current DocBook documentation (three files altogether) to sphinx/reStructuredText. For now, all old DocBook documentation was merged into a single handbook, tentatively named "U-Boot Hacker Manual". For some source files, the documentation style was changed to comply with kernel-doc; no functional changes were applied.
