All FCHs with the older SPI controller don't have the SPI registers 0x45 and 0x47. Most of the FCHs with SPI100 have both the old (first 32bit register of SPI MMIO) and the new (SPI MMIO 0x45 and 0x47) mapping, but the newest SoCs don't have the old mapping any more. Also spi100_spi_send_command already accesses registers 0x48 and 0x4b which aren't available on the old spi controllers, but are available on the spi100 controllers. when 0x48 and 0x4b are available, 0x45 and 0x47 will also be available. -- To view, visit https://review.coreboot.org/c/flashrom/+/63422 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-Change-Id: If42130757331f4294b5a42c848557d3287f24fc3 Gerrit-Change-Number: 63422 Gerrit-PatchSet: 2 Gerrit-Owner: Karthik Ramasubramanian <kramasub(a)google.com> Gerrit-Reviewer: Edward O'Callaghan <quasisec(a)chromium.org> Gerrit-Reviewer: Felix Held <felix-coreboot(a)felixheld.de> Gerrit-Reviewer: Jon Murphy <jpmurphy(a)google.com> Gerrit-Reviewer: Raul Rangel <rrangel(a)chromium.org> Gerrit-Reviewer: Robert Zieba <robertzieba(a)google.com> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Karthikeyan Ramasubramanian <kramasub(a)chromium.org> Gerrit-CC: Nico Huber <nico.h(a)gmx.de> Gerrit-CC: Paul Menzel <paulepanter(a)mailbox.org> Gerrit-Attention: Robert Zieba <robertzieba(a)google.com> Gerrit-Attention: Paul Menzel <paulepanter(a)mailbox.org> Gerrit-Attention: Jon Murphy <jpmurphy(a)google.com> Gerrit-Attention: Edward O'Callaghan <quasisec(a)chromium.org> Gerrit-Attention: Karthik Ramasubramanian <kramasub(a)google.com> Gerrit-Comment-Date: Thu, 07 Apr 2022 20:03:19 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Robert Zieba <robertzieba(a)google.com> Comment-In-Reply-To: Edward O'Callaghan <quasisec(a)chromium.org> Comment-In-Reply-To: Karthik Ramasubramanian <kramasub(a)google.com> Comment-In-Reply-To: Felix Held <felix-coreboot(a)felixheld.de> Gerrit-MessageType: comment
