The i2c bus may be blocked by anz slave device if the system was reset
during a transaction, leading to ddr initialisation failures.
Implement a workaround releasing the bus by toggling scl 9 times.

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).

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
