Previously multistrap was used to download and create an ubuntu rootfs;
but multistrap failed under docker build since it required binfmt
installed.

This technique of installing ubuntu rootfs is totally different method,
takes more time to build but works under the native runme.sh script and
under docker build.

The method idea is -
1. Build a simple rootfs with a kernel that can be booted via
qemu-system-aarch64.
2. Install an initi script called S99bootstrap-ubuntu.sh under
/etc/init.d.
3. Run a qemu-system-aarch64 virtual machine with 1GByte of system
memory and use cortex-a57 which is the closed to cortex-a72,
virtualization wise and has the buildroot rootf as initrd and the
destination ubuntu-core.ext4 partition as a drive.
4. The VM would boot the kernel, mount the rootfs and run the
S99bootstrap-ubuntu.sh script
5. The script would download an ubuntu base image and then 'apt install'
in a virtual chrooted environment the reset of the packages to make this
rootfs to be bootable.
6. Use 'reboot' in the VM which triggers the '-no-reboot' flag for qemu
that makes the vm exit; and thus installation is continued.
7. ubuntu-core.ext4 partition is now ready to be used further on for
imaging and installations.

Using conditional load and jump in RCW and boot=auto as a parameter for
ATF it is possible now to build a single image that can be booted from
SPI, SD or eMMC.

Still there is a small difference BL2 stage where on SPI it is located
on address 0x0 and SD/eMMC is located with 0x1000 (8 blocks of 512
bytes) offset.

Additional feature is runtime RCW file creation; this will be further
enhanced to create the SERDES and PLL multipliers creation in runtime
too.

1. add buildroot to the build targets (still not used as rootfs).
2. bootstrap ubuntu 19.04 rootfs using multistrap and
qemu-aarch64-static
3. build and install restool under ubuntu rootfs
4. Image and dtb are added to ubuntu 19.04 partition
5. The micro SD now contains a file called ubuntu-core.img. That image
can be copied to NVME drive, SATA drive or USB drive and using it's
PARTUUID the kernel finds the right root partition and mounts it.

To install the image on NVME M.2 drive; stop u-boot count down and run -

load mmc 0:1 0xa4000000 ubuntu-core.img
nvme scan
nvme write 0xa4000000 0 262144
nvme write 0xac000000 262144 262144
nvme write 0xb4000000 524288 204800

To install to SATA drive -
load mmc 0:1 0xa4000000 ubuntu-core.img
scsi reset
scsi write 0xa4000000 0 0xb2000

then run 'boot'.

First thing after booting ubuntu -
1. resize the main partition to include bigger partition than the default.
2. run resize2fs /dev/nvme0n1p1 or resize2fs /dev/sda1 to enlarge the
rootfs to new partition
3. run 'dhclient'
4. get ntp clock by running 'ntpdate pool.ntp.org'
5. store clock to RTC chip 'hwclock -w'
