Change in ...flashrom[master]: ichspi: Add Apollo Lake support
by Nico Huber (Code Review) 06 Jul '19

Nico Huber has uploaded this change for review. ( https://review.coreboot.org/c/flashrom/+/30995 Change subject: ichspi: Add Apollo Lake support ...................................................................... ichspi: Add Apollo Lake support It's almost identical to 100 series PCHs and later. There are some addition FREGs (12..15). To not clutter the `if` conditions further, make more use of `switch` statements. Tested on Kontron mAL10. Mark it as DEP as usually the last sector is not covered by the descriptor layout and can't be read.

Change in ...flashrom[master]: dediprog: Break apart large (>=32MiB) transfers
by David Hendricks (Code Review) 20 Jun '19

20 Jun '19

David Hendricks has uploaded this change for review. ( https://review.coreboot.org/c/flashrom/+/30520 Change subject: dediprog: Break apart large (>=32MiB) transfers ...................................................................... dediprog: Break apart large (>=32MiB) transfers The 2-byte length defined in the command spec appears to be 1-based, that is to say that we can transfer 65536 - 1 data packets of 512 bytes in one bulk read request, just shy of 32MiB. Attempting to read >=32MiB at once will result in bulk read failure (with "SPI bulk read failed!" messages). This patch breaks the transfer at 32MiB - 512 bytes to avoid that. Tested using an SF600 (FW v7.2.21), IS25LP256D, W25Q256JV, and MX25L25735.
