Interesting reading for minimalists, esp mes folks? :)

Hi minimalists :)

In case you hadn't yet come across this (LWN did a piece [5] about a year ago,
which was the first I heard of it. (Chasing a dream led me to check
more current status) Enjoy :)

To whet your appetite (from the README at [4]):

Bao has no external dependencies, such as on privileged VMs running untrustable, 
large monolithic general-purpose operating systems (e.g., Linux), and, as such, 
encompasses a much smaller TCB.

Bao originally targets the Armv8-A architecture, but there is experimental support
for the RISC-V architecture. The full list of supported (and work in progress) 
platforms is presented below:

- [x] Xilinx Zynq UltraScale+ MPSoC ZCU102 (Armv8-A)
- [x] Xilinx Zynq UltraScale+ MPSoC ZCU104 (Armv8-A)
- [x] Ultra96 Zynq UltraScale+ ZU3EG (Armv8-A)
- [x] 96Boards HiKey 960 (Armv8-A)
- [ ] NXP MCIMX8M-EVK (Armv8-A) - wip
- [ ] NXP MCIMX8QM-CPU (Armv8-A) - wip
- [ ] 96Boards ROCK960 (Armv8-A) - wip
- [ ] QEMU virt (Armv8-A) - wip
- [ ] QEMU virt (RISC-V rv64) - wip

**NOTE**: This is work in progress! Don't expect things to be complete. 
Use at your own risk.
