I've missed appending the changelog:

changes since v1:
  - rebased to latest tree
  - correctly check return code of otp_ops->is_locked() in 
spi_nor_mtd_otp_info()
  - use correct bouncebuf for spi command in spi_nor_otp_lock_sr2()
  - add cleanup patch to consolidate some of the "if (spimem) {} else {}" 
patterns
  - add otp support for macronix and similar flashes
  - moved otp code into core.c because it is used across different 
vendors
  - use generic naming, eg. spi_nor_otp_lock_sr2() instead of 
winbond_otp_lock()
