The trace from S71PL129NC0 ball D5 (flash reset) goes to a pull-up resistor and
to a microvia at (5130,717).  On L7 this microvia connects to an inner via at
(5141,681).  Found it on L2, trace from inner via goes to a microvia to L1 at
(4676,922).  On L1 the trace goes to a pair of resistor footprints, the left
one is populated, the right one is not.  Tracing the populated branch: the
trace goes to a microvia at (4516,1047).  On L2 the microvia connects to an
inner via at (4540,1032).  Found it on L4, the trace goes through another inner
via at (3718,1052) and finally to yet another inner via at (1699,1348).

Tracing the populated branch from (1699,1348): found it on L2, goes to a
microvia back to L1 at (1673,1352).  It is TCXOEN!

Tracing the unpopulated resistor branch: microvia from L1 to L2 at (4665,892).
On L2 the trace goes two ways: to another microvia back to L1 at (4142,802) and
to an inner via at (5150,834).  The microvia back to L1 at (4142,802) falls on
Calypso ball F4 - that's FDP!  Tracing the inner via at (5150,834): found it on
L7, trace obscured by damage, apparently ends at (5169,751), there may have
been a microvia around (5166,709).  It might be plausibly connected to the
WP#/ACC pin, which is also pulled up like RST#, but the damage makes it
impossible to trace for certain.
