Change in flashrom[master]: spi25: Revise decision when to enter/exit 4BA mode
by Nico Huber (Code Review) 12 Dec '17

12 Dec '17

Hello Paul Menzel, David Hendricks, build bot (Jenkins), I'd like you to reexamine a change. Please visit https://review.coreboot.org/22422 to look at the new patch set (#5). Change subject: spi25: Revise decision when to enter/exit 4BA mode ...................................................................... spi25: Revise decision when to enter/exit 4BA mode Instead of arbitrarily deciding whether to enter 4BA mode in the flash chip's declaration, advertise that entering 4BA mode is supported and only enter it if the SPI master supports 4-byte addresses. If not, exit 4BA mode (the chip might be in 4BA mode after reset). If we can't assure the state of 4BA mode, we bail out to simplify the code (we'd have to ensure that we don't run any instructions that can usually be switched to 4BA mode otherwise). Two new feature flags are introduced: * FEATURE_4BA_ENTER: Can enter/exit 4BA mode with instructions 0xb7/0xe9 w/o WREN. * FEATURE_4BA_ENTER_WREN Can enter/exit 4BA mode with instructions 0xb7/0xe9 after WREN. FEATURE_4BA_SUPPORT is dropped, it's completely implicit now. Also, draw the with/without WREN distinction into the enter/exit functions to reduce code redundancy.

Change in flashrom[master]: spi_master: Introduce SPI_MASTER_4BA feature flag

Hello Paul Menzel, David Hendricks, 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 (#6). 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.

If you're referring to chip erase commands, those are handled using I'm talking about the block erase commands. If the core read/erase/write code tries a native 4BA erase and the master doesn't support it, we end up here. Maybe we should handle native 4BA erase commands differently. e.g. put them in a separate list? or bail out earlier? Though, my last plan was to ask the master anyway if an erase command is supported (e.g. 3BA commands may not be as well in case of locked opcodes on Intel) instead of going through all the preparations and trying. -- To view, visit https://review.coreboot.org/22421 To unsubscribe, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Ife66e3fc49b9716f9c99cad957095b528135ec2c Gerrit-Change-Number: 22421 Gerrit-PatchSet: 5 Gerrit-Owner: Nico Huber <nico.h(a)gmx.de> Gerrit-Reviewer: David Hendricks <david.hendricks(a)gmail.com> Gerrit-Reviewer: Nico Huber <nico.h(a)gmx.de> Gerrit-Reviewer: Paul Menzel <paulepanter(a)users.sourceforge.net> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-Comment-Date: Tue, 12 Dec 2017 18:42:07 +0000 Gerrit-HasComments: Yes
