Patch set updated for coreboot: x86: don't create MAINBOARDDIR/romstage.inc for !ROMCC boards
by Aaron Durbin 04 Sep '15

04 Sep '15

Aaron Durbin (adurbin(a)chromium.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/11503 -gerrit commit e19178e89eacaf7562f893e3d182beadcbbc30fc Author: Aaron Durbin <adurbin(a)chromium.org> Date: Thu Sep 3 11:01:17 2015 -0500 x86: don't create MAINBOARDDIR/romstage.inc for !ROMCC boards Previously, the x86 romstage build process was unconditionally creating a romstage.inc and adding it to crt0s. This step is inherently not necessary in the !ROMCC case becaue the romstage.inc was created by the compiler outputting assembler. That means MAINBOARDDIR/romstage.c is truly a C environment that requires some sort of assembler stub to call into (cache_as_ram.inc from the chipset dirs). Therefore, remove this processing. The result is that MAINBOARDDIR/romstage.c can use the normal build steps in creating an object and linking. The layout of romstage.elf will change but that's only from a symbol perspective. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built multitude of boards. Compared readelf -e output.

Patch set updated for coreboot: linking: lay the groundwork for a unified linking approach
by Aaron Durbin 04 Sep '15

Aaron Durbin (adurbin(a)chromium.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/11507 -gerrit commit 2537ea75b8151e6fc52f2b49019a234957ae90e3 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Thu Sep 3 22:49:36 2015 -0500 linking: lay the groundwork for a unified linking approach Though coreboot started as x86 only, the current approach to x86 linking is out of the norm with respect to other architectures. To start alleviating that the way ramstage is linked is partially unified. A new file, program.ld, was added to provide a common way to link stages by deferring to per-stage architectural overrides. The previous ramstage.ld is no longer required. Note that this change doesn't handle RELOCATABLE_RAMSTAGE because that is handled by rmodule.ld. Future convergence can be achieved, but for the time being that's being left out. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built a myriad of boards.

Those files were then concatenated together, and the resulting file was added to the build dependencies for romstage proper. Now romstage.S is added that can be built using the default object file rules. The generated romstage.inc is pulled in by way of an #include in the newly added romstage.S.

Aaron Durbin (adurbin(a)chromium.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/11495 -gerrit commit 7598c0e26376e9284ab89fca78d0d15c01fb31f1 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Thu Sep 3 00:41:29 2015 -0500 x86: bootblock: remove linking and program flow from build system The build system was previously determining the flow and linking scripts bootblock code by the order of files added to the bootblock_inc bootblock-y variables.Those files were then concatenated together and built by a myriad of make rules. Now bootblock.S and bootblock.ld is added so that bootblock can be built and linked using the default build rules. CHIPSET_BOOTBLOCK_INCLUDE is introduced in order to allow the chipset code to place include files in the path of the bootblock program -- a replacement for the chipset_bootblock_inc make variable. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built vortex, rambi, and some asus boards.
