read ARM Architecture Reference Manual
2.6.5 Data Abort
There are three Abort Model in ARM arch.

Early Abort Model: used in some ARMv3 and earlier implementations. In this
model, base register wirteback occurred for LDC,LDM,STC,STM instructions, and
the base register was unchanged for all other instructions. (oldest)

Base Restored Abort Model: If a Data Abort occurs in an instruction which
specifies base register writeback, the value in the base register is
unchanged. (strongarm, xscale)

Base Updated Abort Model: If a Data Abort occurs in an instruction which
specifies base register writeback, the base register writeback still occurs.
(arm720T)

read PART B
chap2 The System Control Coprocessor  CP15
2.4 Register1:control register
L(bit 6): in some ARMv3 and earlier implementations, the abort model of the
processor could be configured:
0=early Abort Model Selected(now obsolete)
1=Late Abort Model selceted(same as Base Updated Abort Model)

on later processors, this bit reads as 1 and ignores writes.
-------------------------------------------------------------
So, if lateabtSig=1, then it means Late Abort Model(Base Updated Abort Model)
    if lateabtSig=0, then it means Base Restored Abort Model
