SFDP parameter table header 0/1:
ID 0x00, version 1.8
Length 36 B, Parameter Table Pointer 0x000080
Parsing JEDEC flash parameter table... 3-Byte only addressing.
Status register is non-volatile and the standard does not allow vendors to tell us whether EWSR/WREN is needed for status register writes - assuming EWSR.
Write chunk size is at least 64 B.
Flash chip size is 8192 kB.

SFDP has autodetected a flash chip which is not natively supported by flashrom yet.
All standard operations (read, verify, erase and write) should work, but to support all possible features we need to add them manually.
You can help us by mailing us the output of the following command to flashrom@flashrom.org:
'flashrom -VV [plus the -p/--programmer parameter]'
Thanks for your help!
