Patch merged into coreboot/master: 8256a9b haswell: align pei_data structure with intel-framework
by gerrit＠coreboot.org 14 Mar '13

14 Mar '13

the following patch was just integrated into master: commit 8256a9b715df14dc8914b641796344ac513cb889 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Thu Nov 29 17:18:53 2012 -0600 haswell: align pei_data structure with intel-framework The intel-framework code has an updated pei_data structure. Use the new structure and revision. Also, remove the scrambler seed saving in CMOS since that appears to be handled in the saved data from the reference code.

Patch merged into coreboot/master: f6933a6 Mainboard: Add support for Grays Reef

the following patch was just integrated into master: commit f6933a6f56f8bdc7e249b6629824acce646d5f6a Author: Aaron Durbin <adurbin(a)chromium.org> Date: Tue Oct 30 09:09:39 2012 -0500 Mainboard: Add support for Grays Reef Grays Reef is one of Intel's CRBs for the Haswell processor. The platform is named Shark Bay. GPIOs were the main focus so IRQ routing and ACPI still needs to be further looked at.

It seems this is a lot simpler now (so far) which is good. To test, boot to chromeos with 3.7 kernel + i915.preliminary_hw_support=1 and see that the i915 driver complains a lot less than before and that a splashscreen is displayed.

Patch merged into coreboot/master: 50a3464 x86: SMM Module Support
by gerrit＠coreboot.org 14 Mar '13

14 Mar '13

the following patch was just integrated into master: commit 50a34648cdc7fc55e1fa75d51ece608c0e27245a Author: Aaron Durbin <adurbin(a)chromium.org> Date: Thu Jan 3 17:38:47 2013 -0600 x86: SMM Module Support Add support for SMM modules by leveraging the RMODULE lib. This allows for easier dynamic SMM handler placement. The SMM module support consists of a common stub which puts the executing CPU into protected mode and calls into a pre-defined handler. This stub can then be used for SMM relocation as well as the real SMM handler. For the relocation one can call back into coreboot ramstage code to perform relocation in C code. The handler is essentially a copy of smihandler.c, but it drops the TSEG differences. It also doesn't rely on the SMM revision as the cpu code should know what processor it is supported. Ideally the CONFIG_SMM_TSEG option could be removed once the existing users of that option transitioned away from tseg_relocate() and smi_get_tseg_base(). The generic SMI callbacks are now not marked as weak in the declaration so that there aren't unlinked references. The handler has default implementations of the generic SMI callbacks which are marked as weak. If an external compilation module has a strong symbol the linker will use that instead of the link one. Additionally, the parameters to the generic callbacks are dropped as they don't seem to be used directly. The SMM runtime can provide the necessary support if needed.

the following patch was just integrated into master: commit 5ca4f4119bf00a1ec64358f3e6b41d696b1dc123 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Thu Mar 7 23:22:24 2013 -0600 libpayload: add support for vboot_handoff The vboot_handoff structure needs to be parsed from the coreboot tables. Add a placeholder in sysinfo as well as the ability to parse the coreboot table entry concering the vboot_handoff structure. Built with unified boot loader and ebuild changes. Can find and use the VbInitParams for doing kernel selection.

Patch merged into coreboot/master: 1cb414d libpayload: Turn the endian conversion macros into functions.
by gerrit＠coreboot.org 14 Mar '13

the following patch was just integrated into master: commit 1cb414de638d6885ad3a8510594ea1df7d4d96a6 Author: Gabe Black <gabeblack(a)google.com> Date: Fri Mar 8 04:38:13 2013 -0800 libpayload: Turn the endian conversion macros into functions. In their current macro form, any arguments that are expressions will be evaluated multiple times. That can cause problems if they have side effects, and might not even compile if the overall expression is ambiguous, for instance if you pass in foo++. Built with code that previously wouldn't compile because the macros expanded to ambiguous expressions.
