Change in coreboot[master]: x86: Put bootblock startup code into .text._start section
by Julius Werner (Code Review) 03 Dec '20

03 Dec '20

Hello Aaron Durbin, I'd like you to do a code review. Please visit https://review.coreboot.org/c/coreboot/+/46834 to review the following change. Change subject: x86: Put bootblock startup code into .text._start section ...................................................................... x86: Put bootblock startup code into .text._start section The initial bootblock assembly code on x86 is just put into the .text section, which just happens to come before all the individual .text.* function sections in the program.ld script. So it tends to be at the start of the image, bit if you inserted another linker script section with contents before .text, it would cause a problem. (I'm not sure if it's an architectural requirement for _start16bit to come at the start of the image, but at least its 4K alignment requirement would waste a lot of space if it didn't.) This patch moves the section to .text._start which is the name other architectures use for the code they want in the very front of the image and which is listed first in program.ld.

Change in coreboot[master]: cbfstool: Hide hash printing behind -v and add to parseable output
by Julius Werner (Code Review) 03 Dec '20

03 Dec '20

Hello Patrick Georgi, Aaron Durbin, I'd like you to do a code review. Please visit https://review.coreboot.org/c/coreboot/+/41119 to review the following change. Change subject: cbfstool: Hide hash printing behind -v and add to parseable output ...................................................................... cbfstool: Hide hash printing behind -v and add to parseable output With the upcoming introduction of CBFS verification, a lot more CBFS files will have hashes. The current cbfstool default of always printing hash attributes when they exist will make cbfstool print very messy. Therefore, hide hash attribute output unless the user passed -v. It would also be useful to be able to get file attributes like hashes in machine parseable output. Unfortunately, our machine parseable format (-k) doesn't really seem designed to be extensible. To avoid breaking older parsers, this patch adds new attribute output behind -v (which hopefully no current users pass since it doesn't change anything for -k at the moment). With this patch cbfstool print -k -v may print an arbitrary amount of extra tokens behind the predefined ones on a file line. Tokens always begin with an identifying string (e.g. 'hash'), followed by extra fields that should be separated by colons. Multiple tokens are separated by the normal separator character (tab). cbfstool print -k -v may also print additional information that applies to the whole CBFS on separate lines. These lines will always begin with a '[' (which hopefully nobody would use as a CBFS filename character although we technically have no restrictions at the moment).

Change in coreboot[master]: cbfstool: Rename cbfs_walk() to cbfs_legacy_walk()

Hello Patrick Georgi, Aaron Durbin, I'd like you to do a code review. Please visit https://review.coreboot.org/c/coreboot/+/41118 to review the following change. Change subject: cbfstool: Rename cbfs_walk() to cbfs_legacy_walk() ...................................................................... cbfstool: Rename cbfs_walk() to cbfs_legacy_walk() This function name clashes with cbfs_walk() in the new commonlib CBFS stack, so rename it to cbfs_legacy_walk(). While we could replace it with the new commonlib implementation, it still has support for certain features in the deprecated pre-FMAP CBFSes (such as non-standard header alignment), which are needed to handle old files but probably not something we'd want to burden the commonlib implementation with. So until we decide to deprecate support for those files from cbfstool as well, it seems easier to just keep the existing implementation here.

Change in coreboot[master]: cbfstool: Use cbfs_serialized.h and standard vboot helpers
by Julius Werner (Code Review) 03 Dec '20

03 Dec '20

Hello Patrick Georgi, Aaron Durbin, I'd like you to do a code review. Please visit https://review.coreboot.org/c/coreboot/+/41117 to review the following change. Change subject: cbfstool: Use cbfs_serialized.h and standard vboot helpers ...................................................................... cbfstool: Use cbfs_serialized.h and standard vboot helpers This patch reduces some code duplication in cbfstool by switching it to use the CBFS data structure definitions in commonlib rather than its own private copy. In addition, replace a few custom helpers related to hash algorithms with the official vboot APIs of the same purpose.

Change in coreboot[master]: lib/trace: Remove TRACE support
by Kyösti Mälkki (Code Review) 02 Dec '20

02 Dec '20

Kyösti Mälkki has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/45757 ) Change subject: lib/trace: Remove TRACE support ...................................................................... lib/trace: Remove TRACE support Looks like the option is generally not compatible with garbage collections. Nothing is inlined, is_smp_boot() no longer evaluates to constant false and thus the symbols from secondary.S would need to be present for the build to pass after we set SMP=n.
