Jagan,

I think get_maintainer.pl may have given me an old email address for
you and you may have missed it on the mailing list. Either way if you
get a chance I'd like hear what you think. I'm not sure which
tree/branch you're working with (u-boot-spi
 master?) but if you need it rebased just let me know.

Thanks,
George

[U-Boot] [PATCH 0/5] sf: Add support for status register protect

[George McCollister]

Many SPI NOR flash devices support status register protection through
one or two status register protection bits. Protection of the status
register is essential in defending the device from rogue software which
may attempt to modify block protection bits in order to make malicious
modifications to the data stored in flash. This patch series adds
status register protect support for STMICRO, SST, Winbond and Spansion
devices and also implements an sf sub-command to set the used
protection method.

George McCollister (5):
  sf: Add status register protection mechanism
  sf: Add status register protect for STMICRO, SST
  sf: Use stm_lock/unlock for Spansion and Winbond
  sf: Add status register protect for Winbond
  sf: Add sr-protect sub-command
