Just tested this; looks like it's required here, without it the second
core fails to start up:
[ 0.064277] smp: Bringing up secondary CPUs ...
[ 1.067163] CPU1: failed to boot: -110
[ 1.069683] smp: Brought up 1 node, 1 CPU
[ 1.072470] SMP: Total of 1 processors activated (48.00 BogoMIPS).
SBOOT on my tablet claims the version is T310XXSBQB2, so it should match
with the one you checked.
Best regards
