2020-06-23src/*: Update makefiles to exclude x86 code from psp-verstageMartin Roth
The assumption up to this point was that if the system had an x86 processor, verstage would be running on the x86 processor. With running verstage on the PSP, that assumption no longer holds true, so exclude pieces of code that cause problems for verstage on the PSP. This change will add these files to verstage only if the verstage architecture is X86 - either 32 or 64 bit.

2019-11-03cpu/x86/tsc: Flip and rename TSC_CONSTANT_RATE to UNKNOWN_TSC_RATEKyösti Mälkki
The x86 timers are a bit of a mess. Cases where different stages use different counters and timestamps use different counters from udelays. The original intention was to only flip TSC_CONSTANT_RATE Kconfig to NOT_CONSTANT_TSC_RATE. The name would be incorrect though, those counters do run with a constant rate but we just lack tsc_freq_mhz() implementation for three platforms. Note that for boards with UNKNOWN_TSC_RATE=y, each stage will have a slow run of calibrate_tsc_with_pit(). This is easy enough to fix with followup implementation of tsc_freq_mhz() for the platforms. Implementations with LAPIC_MONOTONIC_TIMER typically will not have tsc_freq_mhz() implemented and default to UNKNOWN_TSC_RATE. However, as they don't use TSC for udelay() the slow calibrate_tsc_with_pit() is avoided. Because x86/tsc_delay.tsc was using two different guards and nb/via/vx900 claimed UDELAY_TSC, but pulled UDELAY_IO implementation, we also switch that romstage to use UDELAY_TSC.

2015-10-14x86: add standalone verstage supportAaron Durbin
To support x86 verstage one needs a working buffer for vboot. That buffer resides in the cache-as-ram region which persists across verstage and romstage. The current assumption is that verstage brings cache-as-ram up and romstage tears cache-as-ram down. The timestamp, cbmem console, and the vboot work buffer are persistent through in both romstage and verstage. The vboot work buffer as well as the cbmem console are permanently destroyed once cache-as-ram is torn down. The timestamp region is migrated. When verstage is enabled the assumption is that _start is the romstage entry point. It's currently expected that the chipset provides the entry point to romstage when verstage is employed. Also, the car_var_*() APIs use direct access when in verstage since its expected verstage does not tear down cache-as-ram. Lastly, supporting files were added to verstage-y such that an x86 verstage will build and link. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built and booted glados using separate verstage.

2013-05-07x86: add TSC_CONSTANT_RATE optionAaron Durbin
Some boards use the local apic for udelay(), but they also provide their own implementation of udelay() for SMM. The reason for using the local apic for udelay() in ramstage is to not have to pay the penalty of calibrating the TSC frequency. Therefore provide a TSC_CONSTANT_RATE option to indicate that TSC calibration is not needed. Instead rely on the presence of a tsc_freq_mhz() function provided by the cpu/board. Additionally, assume that if TSC_CONSTANT_RATE is selected the udelay() function in SMM will be the tsc.

2010-09-30Rename build system variables to be more intuitive, andPatrick Georgi
at the same time let the user specify sources instead of object files: - objs becomes ramstage-srcs - initobjs becomes romstage-srcs - driver becomes driver-srcs - smmobj becomes smm-srcs The user servicable parts are named accordingly: ramstage-y, romstage-y, driver-y, smm-y Also, the object file names are properly renamed now, using .ramstage.o, .romstage.o, .driver.o, .smm.o suffixes consistently. Remove stubbed out via/epia-m700 dsdt/ssdt files - they didn't easily fit in the build system and aren't useful anyway.

The remaining question of Uwe's is a deeper problem: --- We'll have to check if this works. From a quick glance the Rumba does not have the mmx related lines (which _are_ in Makefile.romccboard.inc, though): crt0-y += ../../../../src/cpu/x86/fpu/enable_fpu.inc crt0-y += ../../../../src/cpu/x86/mmx/enable_mmx.inc crt0-y += auto.inc crt0-y += ../../../../src/cpu/x86/mmx/disable_mmx.inc --- We're going to need a whole variant of this standard mainboard OR we're going to have to make (some) of the unconditional includes above conditional.
