Compiling Linux kernel with making olddefconfig helps set all new config
symbols to their default values without prompting.

This is "working", but only to the extent that it boots, works for a while, then hangs :-(
Build here, then
cp cpukernel ~/oreboot/src/mainboard/sunxi/nezha/
cp sun20i-d1-nezha.dtb ~/oreboot/src/mainboard/sunxi/nezha/
cd ~/oreboot/src/mainboard/sunxi/nezha/
PAYLOAD_B=cpukernel PAYLOAD_C=sun20i-d1-nezha.dtb make run

The makefile now builds the u-root command when
make fetch
is invoked.
It runs the u-root command it builds, rather than
run u-root.go
Further, now that a set of bugs are fixed in cpud, we can now fire up
a console shell, and include lots of commands, which makes life a
LOT easier.

This supports adding the DT node "linux,uefi-secure-boot" into the EFI
Stub for kexecing Ubuntu 20.04+. Otherwise, the Ubuntu will make the
kernel crash.

These config files are for
5.15.0 : cpuflash.config
5.4.65 : cpuflash-5.4.65.config
They start a cpu daemon on boot.
The cpu daemon in turns starts a dhclient and a shell.
You can type commands.
They use pciserial for earlyprintk beacause their serial
hardware does not work in any way I can find.
5.4.65 can't run the on-board ethernet, so I have to use
a usb serial when I boot 5.4.65.
They have a simple standard command line. You can override
it via grub or kexec, but if you don't, looks like this
for both of them:
CONFIG_CMDLINE="console=tty0 earlyprintk=pciserial,force,1:0.0,115200"
While each kernel can kexec itself, they can not kexec the other.

5.4.65 kexec'ing 5.15.0: boots, but no working ethernet

I had to use an asix usb to ethernet for now, but at least this POS is
sort of working:
rminnich@a300:~/linuxboot/mainboards/aeeon/i11$ cpu x date
Wed Jan 5 05:47:21 PM PST 2022
rminnich@a300:~/linuxboot/mainboards/aeeon/i11$
On to fixing on-board ethernet.
Would be nice if the folks at aeeon could learn not to include
30-year-old dead networks like FDDI and ATM in their
kernel configs, eh? It's just Not That Hard.
Next steps: prune this config more. Start testing kexec.
