Hello Paul Menzel, David Hendricks, Stefan Reinauer, build bot (Jenkins), I'd like you to reexamine a change. Please visit https://review.coreboot.org/22421 to look at the new patch set (#7). Change subject: spi_master: Introduce SPI_MASTER_4BA feature flag ...................................................................... spi_master: Introduce SPI_MASTER_4BA feature flag Add a feature flag SPI_MASTER_4BA to `struct spi_master` that advertises programmer-side support for 4-byte addresses in generic commands (and read/write commands if the master uses the default implementations). Set it for all masters that handle commands address-agnostic. Don't prefer native 4BA instructions if the master doesn't support them.

Change in flashrom[master]: spi: Move ICH BBAR quirk out of the way
by Nico Huber (Code Review) 28 Dec '17

28 Dec '17

Nico Huber has submitted this change and it was merged. ( https://review.coreboot.org/22396 ) Change subject: spi: Move ICH BBAR quirk out of the way ...................................................................... spi: Move ICH BBAR quirk out of the way Get rid of the layering violations around ICH's BBAR. Move all the weird address handling into (surprise, surprise) `ichspi.c`. Might fix writes for the `BBAR != 0` case by accident. Background: Some ICHs have a BBAR (BIOS Base Address Configuration Register) that, if set, limits the valid address range to [BBAR, 2^24). Current code lifted addresses for REMS, RES and READ operations by BBAR, now we do it for all addresses in ichspi. Special care has to be taken if the BBAR is not aligned by the flash chip's size. In this case, the lower part of the chip (from BBAR aligned down, up to BBAR) is inacces- sible (this seems to be the original intend behind BBAR) and has to be left out in the address offset calculation.
