Dear flashrom team
Hello. I am Yuta Teshima. I tested Micron MT25QL512(RW187) with Raspberry Pi 2(linux_spi). PROBE, READ, ERASE, WRITE operations worked well. I attached only ’READ' log this email due to size limit. If you need more log, please require me.
original file ac3f8e07dd70be3624eeede1a8468c8a RW187_64MB.bin
write into RW187 and read again ac3f8e07dd70be3624eeede1a8468c8a 64MB.written_by_flashrom.bin
Thanks,

This chip may contain one-time programmable memory. flashrom cannot read and may never be able to write it, hence it may not be able to completely clone the contents of this chip (see man page for details). === This flash part has status UNTESTED for operations: PROBE READ ERASE WRITE The test status of this chip may have been updated in the latest development version of flashrom. If you are running the latest development version, please email a report to flashrom@flashrom.org if any of the above operations work correctly for you with this flash chip. Please include the flashrom log file for all operations you tested (see the man page for details), and mention which mainboard or programmer you tested in the subject line. Thanks for your help! Block protection is disabled. Reading flash... done.
