2012-11-27Get rid of drivers classPatrick Georgi
The use of ramstage.a required the build system to handle some object files in a special way, which were put in the drivers class. These object files didn't provide any symbols that were used directly (but only via linker magic), and so the linker never considered them for inclusion. With ramstage.a gone, we can drop this special class, too.

2012-11-27Drop ramstage.aPatrick Georgi
ramstage.a has two issues: 1. duplicate source filenames don't survive the ar(1) treatment properly (so files aren't considered) 2. ld doesn't resolve symbols if it isn't forced to, in particular no overrides of weak symbols Downside: The resulting binaries get slightly larger. Link time optimizations should fix that, as would tighter rules in the build system (to not compile unused code in the first place).

At boot time when the ACPI tables are created and the location of GNVS is determined then save that address for resume time. This also sets the values of USB charging in S3/S5 to the expected default values for Stout/Butterfly that were not set correctly.

2012-11-14SMM: Pass the ACPI GNVS pointer via state save mapDuncan Laurie
Instead of hijacking some random memory addresses to relay the GNVS pointer to SMM we can use EBX register during the write to APM_CNT register when the SMI is triggered.

2012-11-14SMM: Avoid use of global variables in SMI handlerDuncan Laurie
Using global variables with the TSEG is a bad idea because they are not relocated properly right now. Instead make the variables static and add accessor functions for the rest of SMM to use. At the same time drop the tcg/smi1 pointers as they are not setup or ever used. (the debug output is added back in a subsequent commit) Change-Id: If0b2d47df4e482ead71bf713c1ef748da840073b Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1764 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-11-14SMM: Extract function for finding save state nodeDuncan Laurie
This is currently used by the ELOG GSMI interface but is a good way to pass data to SMM so move the current searching code to a separate function and make it a bit more versatile with the checks it does to find a match so it can be used in other situations.

2012-11-14SMM: Restore GNVS pointer in the resume pathDuncan Laurie
The SMM GNVS pointer is normally updated only when the ACPI tables are created, which does not happen in the resume path. In order to restore this pointer it needs to be available at resume time. The method used to locate it at creation time cannot be used again as that magic signature is overwritten with the address itself. So a new CBMEM ID is added to store the 32bit address so it can be found again easily. A new function is defined to save this pointer in CBMEM which needs to be called when the ACPI tables are created in each mainboard when write_acpi_tables() is called. The cpu_index variable had to be renamed due to a conflict when cpu/cpu.h is added for the smm_setup_structures() prototype.
