The -E flag for sudo has previously been removed to work around some
strange issues.
Re-add the safer --preserve-envs flag listing all the settings currently
available.

This allows in particular to override the serdes configuration again
without editing the runme.sh file - e.g.:
docker run -i -t -v "$PWD":/work -e SERDES=8S_9_2 lx2160a_build -u 0 -g 0

i2c muxes are reset with cpu reset and will default back to channel 0,
while any other channel may still be blocked by a slave.
Detect known muxes and flush all their channels if detected.

Further disable detection logic because it missed rare cases.
Reset unconditionally instead.

The i2c bus may be blocked by anz slave device if the system was reset

Disable high-speed modes in Linux to ensure the microSD operates in the
same mode as it does during rcw and u-boot.

This is a work-around for when the system gets stuck after reset failing
to read from the microSD card.

Directly connect the sfp drivers's (sfp.c) link up and down events to an
LED node in device-tree. This solution is a workaround to the
shortcomings of the generic led triggers framework in combination with
multiple dynamic network interfaces, hot-pluggable phys (inside sfp
modules) and the dpaa2 driver in particular.

The issue is that dpmac.16 to dpmac.18 links up, but unable to
communicate thru those ports.
This patch series does -
1. Fix dpmac.17 phy-handle type since by default the dpmac is RGMII, and
in half-twins case it is thru SGMII.
2. Add to the build script the usage of MC firmware 10.28.100; which is
based on 10.28.1 that fixes the tx/rx thru dpmac.16, dpmac.17 and
dpmac.18. This firmware is only for LSDK-21.08 and will be fixed in
later LSDK releases with newer MC firmwares.
3. Limit recycle queues in the half twins DPC to 1G; this makes it
possible for dpmac.18 to be able to transmit

runme: check DDR speed before doing build

This patch adds most of the fixes to enable secure boot on the LX2160A
COM express -

1. The atf patches fixes the efuse fip fuse loading, and setting of ppwm
register and then gpio handling
2. The u-boot patches adds the secureboot defconfig, and then SVR_WO_E
mask fix
3. Patches for runme.sh script; for building the secure image run with
'SECURE=true ./runme.sh'

The missing piece is u-boot esbc validate code that completes the chain
of trust boot (COT).

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
