ClearFog CX boards rev 1.3 and newer contains on carrier board retimers
to support 100Gbps DAC cables.
When configuring the SERDEses to 10Gbps the retimer configuration needs
to be changed to lock on 10.3125Gbps rate on both the ingress (i2c
address 0x23) and egress (i2c address 0x22) retimers.

For machines that doesn't have sys_eeprom initialized, this can be done
in u-boot by -
sys_eeprom set 0x24 00:11:22:44:11:44
sys_eeprom set 0x2a 0x10
sys_eeprom write

The first command will set the base MAC, the second will define a range
of 16 MAC addresses (LX2 COM can actually go up to 17 MACs).
The third command will save the TLV data. After that reset is required
for the MAC addresses to get effective

1. Poweroff the HoneyComb board by asserting SUS_S5# signal
2. Add USB3.0 DWC3 workaround by disabling parkmode
3. Keep flexspi divisor as default which is ~17MHz. This enables using
the carrier board SPI that is limited in speed due to the analogue mux
connected to it.
4. Remove uefi build and update LSDK20.04 to may-29 update. UEFI is
temporarily hosted at https://github.com/SolidRun/lx2160a_uefi until
fully upstreamed.

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.
