Hello,

I noticed that the mtd lock/unlock are not supported for the cfi_cmdset_0002 of AMD.
I also noticed that there was a cfi_amdstd_lock_varsize implementation in the past.
Why is it removed?
Is it possible to get sector lock protection with this chip.

What other options do I have to protect my flash. I have used the MTD_WRITABLE option 
in the mapping driver but then I can never write to the mtd partition?

Any help is appreciated.

Greetings Gerrit Binnenmars
