sector locks handling for J3 flashes?

[alfred hitch]

Hi,

I am trying to understand how it works for flash'es which have
Hardware flash protection.
Bootloader say locks say 1 partition, then linux kernel / MTD while coming up
reads / probes flash (sector by sector) for locked sectors ?
If yes, and it maintain this in an internal software structure. Using
it when writes to partitions is done ?

I hope linux kernel arm-linux2.4.25-x (snapgear 3.1) has support for
ixdp425 and Intel J3 Strata flash for automatic detection and working
with locked flashes ?

Any one already tried this ?

Regards,
Alfred
