adoc

Semi automated conversion, in part because Pandoc is kind of buggy for adoc:

Some of the commands were along the lines:

    for f in *.md; do pandoc --atx-headers --base-header-level=3 -o ${f%.md}.adoc --wrap=none $f; done
    sed -Ei '/\[\[.*\]\]/d' *.adoc
    while read -r f; do cat $f; echo; done <f >g

+=== Other architectures
+
+The portability of the kernel and toolchains is amazing: change an option and most things magically work on completely different hardware.
+
+==== arm
+
+First build:
+
+....
+./build -a arm
+./run -a arm
+....
+
+Debug:
+
+....
+./run -a arm -d
+# On another terminal.
+./rungdb -a arm
+....
+
+TODOs:
+
+* only managed to run in the terminal interface (but weirdly a blank QEMU window is still opened)
+* GDB not connecting to KGDB. Possibly linked to `-serial stdio`. See also: https://stackoverflow.com/questions/14155577/how-to-use-kgdb-on-arm
+
+==== aarch64
+
+....
+./build -a aarch64
+....
+
+TODOs:
+
+* GDB gives a ton of messages:
++
+....
+no module object found for ''
+....
++
+when you connect. `Ctrl + C` then `c` works though.
+* How to add devices to `-M virt` as we did for `-M versatilepb`
+
+==== mips64
+
+....
+./build -a mips64
