2016-12-08cpu/x86: allow AP callbacks after MP initAaron Durbin
There are circumstances where the APs need to run a piece of code later in the boot flow. The current MP init just parks the APs after MP init is completed so there's not an opportunity to target running a piece of code on all the APs at a later time. Therefore, provide an option, PARALLEL_MP_AP_WORK, that allows the APs to perform callbacks.

2016-02-19x86: add coreboot table entry for TSC infoAaron Durbin
The 8254 (Programmable Interrupt Timer) is becoming optional on x86 platforms -- either from saving power or not including it at all. To allow a payload to still use a TSC without doing calibration provide the TSC frequency information in the coreboot tables. That data is provided by code/logic already employed by platform. If tsc_freq_mhz() returns 0 or CONFIG_TSC_CONSTANT_RATE is not selected the coreboot table record isn't created. BUG=chrome-os-partner:50214 BRANCH=glados TEST=With all subsequent patches confirmed TSC is picked up in libpayload.

2016-01-14arch/x86: add missing license headersMartin Roth
These were mostly written as part of the coreboot project, so get the standard coreboot license header. memmove.c came from the linux kernel, so also gets the standard coreboot v2 license header, but gets the added attribution that it was derived from the linux kernel. Unlike many coreboot files, this file may not be re-licensed as GPL V3.

2015-12-02x86/smm: Initialize SMM on some CPUs one-by-oneDamien Zammit
We currently race in SMM init on Atom 230 (and potentially other CPUs). At least on the 230, this leads to a hang on RSM, likely because both hyperthreads mess around with SMBASE and other SMM state variables in parallel without coordination. The same behaviour occurs with Atom D5xx. Change it so first APs are spun up and sent to sleep, then BSP initializes SMM, then every CPU, one after another. Only do this when SERIALIZE_SMM_INITIALIZATION is set. Set the flag for Atom CPUs.

2015-07-13x86: flatten hierarchyStefan Reinauer
It never made sense to have bootblock_* in init, but pirq_routing.c in boot, and some ld scripts on the main level while others live in subdirectories. This patch flattens the directory hierarchy and makes x86 more similar to the other architectures.
