Hello Subrata, this was required to enable CSE RW region update. Having an EC region prevents us from calculating correct CSE RW offset since this is determined by adding RW region (obtained by HECI query) and ME region in FMAP.
With EC, offset is not proper and system CSE can not jump into RW, causing the system to get into reboot loop:

cse_lite: Number of partitions = 3
cse_lite: Current partition = RO
cse_lite: Next partition = RO
cse_lite: Flags = 0x3
cselite: RO version = 16.0.10.1372 (Status=0x0, Start=0x2000, End=0x19afff)
cse_lite: RW version = 16.0.10.1372 (Status=0x3, Star
cse_lite: Set Boot Partition Info Command (RW) – RW partition failure
HECI: Global Reset(Type:1) Command
