PS1: 
Sergii, I found this old patch and I am not sure it's needed anymore, because the code has changed a lot since then.
The only thing that might be need is test, although if yes it should go to a different file, `chip_wp.c` with other wp tests.
If you think this patch is not needed anymore, them maybe mark it abandoned.

Also while I was looking at the current code in the dummyflasher I made another patch CB:79390 maybe you can have a look.

Thank you!
