Change in flashrom[master]: linux_mtd: Support for NO_ERASE type devices
by David Hendricks (Code Review) 15 Apr '18

15 Apr '18

Hello Paul Menzel, build bot (Jenkins), Brian Norris, I'd like you to reexamine a change. Please visit https://review.coreboot.org/22511 to look at the new patch set (#2). Change subject: linux_mtd: Support for NO_ERASE type devices ...................................................................... linux_mtd: Support for NO_ERASE type devices Some mtd devices have the MTD_NO_ERASE flag set. This means these devices don't require an erase to write and might not have implemented an erase function. We should be conservative and skip erasing altogether, falling back to performing writes over the whole flash. BUG=b:35104688 TESTED=Zaius flash is now written correctly for the 0xff regions.

Hello Paul Menzel, build bot (Jenkins), I'd like you to reexamine a change. Please visit https://review.coreboot.org/25681 to look at the new patch set (#2). Change subject: ch341a_spi: Avoid deprecated libusb functions ...................................................................... ch341a_spi: Avoid deprecated libusb functions libusb 1.0.22 marked libusb_set_debug as deprecated. For such versions of libusb, use libusb_set_option instead.
