tinyprog does the following to support the Adesto flash;

        if flash_id[0:2] == [0x9D, 0x60]:
            # ISSI
            self.security_page_bit_offset = 4
            self.security_page_write_cmd = 0x62
            self.security_page_read_cmd = 0x68
            self.security_page_erase_cmd = 0x64
    
        else:
            # Adesto
            self.security_page_bit_offset = 0
            self.security_page_write_cmd = 0x42
            self.security_page_read_cmd = 0x48
            self.security_page_erase_cmd = 0x44

Memory size: 01
Serial number: ff ff ff ff
$ sudo ./fomu-flash -t 1 -w hello.txt
$ sudo ./fomu-flash -t 1 -v hello.txt
        0: file: 68   spi: ff
        1: file: 65   spi: ff

The Adesto flash has a writeable serial number that they call "Security Page". We could support writing this page in fomu-flash, however that is separate from supporting Adesto parts.

The issue was that the Adesto part appears to require a "Write Enable" call prior to the "Write Volatile" call. Or maybe that's what most parts require. Either way a quirk has been added that fixes this issue.
