(By the way the strange delay and messages in the beginning is due to the user option table (CMOS) and missing cmos.default for this board. That causes a baud rate of 3600 to be used.)
For the builds onward I unselected the user option table (CMOS).
$ grep OPTION_TABLE .config
# CONFIG_USE_OPTION_TABLE is not set
CONFIG_HAVE_OPTION_TABLE=y
Disabling time-stamp collection gives the same result.
$ grep COLLECT_TIMESTAMP .config
# CONFIG_COLLECT_TIMESTAMPS is not set

Adding back the S3 check, like Aaron suggested, doesn’t hang at the same spot, but also doesn’t find the payload.

As suggested by kmalkki, removing select HAVE_ACPI_RESUME from the mainboards Kconfig, and with CBMEM console and time-stamp collection disabled, it boots to the payload.
Testing kmalkki’s patch below on top of latest commit 8c81c6a (google/fizz: Override PL2 and SysPL2 values) in the branch master doesn’t find the payload.
