[U-Boot-Users] u-boot locking ?

I have some (basic) question ..
1) Does u-boot lock the block on which it resides by default ?
I mean the sector /erase block on which u-boot is there, it will be
locked using the block lock bit by default ?
Plafform in question being IXDP 425 with Intel J3 NOR Flash.
2) The flash content changing has to work in block sizes erase -
modify - write cyecles only ??
Reason for all this is that we have few boards on which u-boot is
getting corrupted (on flash image corruption itself).
And so am wondering even if its a noise issue, how can it first cause
an unlock of sector before write.
Any help in understanding of above issues will be really appreciated,
