x86: add TSC_CONSTANT_RATE option 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.

Synchronize rdtsc instructions The CPU can arbitrarily reorder calls to rdtsc, significantly reducing the precision of timing using the CPUs time stamp counter. Unfortunately the method of synchronizing rdtsc is different on AMD and Intel CPUs. There is a generic method, using the cpuid instruction, but that uses up a lot of registers, and is very slow. Hence, use the correct lfence/mfence instructions (for CPUs that we know support it) Change-Id: I17ecb48d283f38f23148c13159aceda704c64ea5 Signed-off-by: Stefan Reinauer <reinauer@google.com> Reviewed-on: http://review.coreboot.org/1422 Reviewed-by: Alexandru Gagniuc <mr.nuke.me@gmail.com> Tested-by: build bot (Jenkins)

smmhandler: on i945..nehalem, crash if LAPIC overlaps with ASEG This mitigates the Memory Sinkhole issue (described on https://github.com/xoreaxeaxeax/sinkhole) by checking for the issue and crashing the system explicitly if LAPIC overlaps ASEG. This needs to happen without a data access (only code fetches) because data accesses could be tampered with. Don't try to recover because, if somebody tried to do shenanigans like these, we have to expect more. Sandybridge is safe because it does the same test in hardware, and crashes. Newer chipsets presumably do the same. This needs to be extended to deal with overlapping TSEG as well.

x86: parallel MP initialization Provide a common entry point for bringing up the APs in parallel. This work is based off of the Haswell one which can be moved over to this in the future. The APs are brought up and have the BSP's MTRRs duplicated in their own MTRRs. Additionally, Microcode is loaded before enabling caching. However, the current microcode loading support assumes Intel's mechanism. The infrastructure provides a notion of a flight plan for the BSP and APs. This allows for flexibility in the order of operations for a given architecture/chip without providing any specific policy. Therefore, the chipset caller can provide the order that is required.

x86: parallel MP initialization Provide a common entry point for bringing up the APs in parallel. This work is based off of the Haswell one which can be moved over to this in the future. The APs are brought up and have the BSP's MTRRs duplicated in their own MTRRs. Additionally, Microcode is loaded before enabling caching. However, the current microcode loading support assumes Intel's mechanism. The infrastructure provides a notion of a flight plan for the BSP and APs. This allows for flexibility in the order of operations for a given architecture/chip without providing any specific policy. Therefore, the chipset caller can provide the order that is required.

x86: add MIRROR_PAYLOAD_TO_RAM_BEFORE_LOADING option Boot speeds can be sped up by mirroring the payload into main memory before doing the actual loading. Systems that would benefit from this are typically Intel ones whose SPI are memory mapped. Without the SPI being cached all accesses to the payload in SPI while being loaded result in uncacheable accesses. Instead take advantage of the on-board SPI controller which has an internal cache and prefetcher by copying 64-byte cachelines using 32-bit word copies.

x86: Set BOOT_MEDIA_SPI_BUS BOOT_MEDIA_SPI_BUS is a Kconfig variable used on some ARM-based platforms to set up CBFS media. It turns out it can also be helpful for setting up the eventlog which is intended to reside on the same SPI flash as CBFS. Setting it for x86 will allow us to remove an assumption about which SPI bus is used for this flash device. Long term this can go away as we come up with a better abstraction for the eventlog's backing store. This is only intended to help us get from here to there.
