2013-05-16x86: add cache-as-ram migration optionAaron Durbin
There are some boards that do a significant amount of work after cache-as-ram is torn down but before ramstage is loaded. For example, using vboot to verify the ramstage is one such operation. However, there are pieces of code that are executed that reference global variables that are linked in the cache-as-ram region. If those variables are referenced after cache-as-ram is torn down then the values observed will most likely be incorrect. Therefore provide a Kconfig option to select cache-as-ram migration to memory using cbmem. This option is named CAR_MIGRATION. When enabled, the address of cache-as-ram variables may be obtained dynamically. Additionally, when cache-as-ram migration occurs the cache-as-ram data region for global variables is copied into cbmem. There are also automatic callbacks for other modules to perform their own migration, if necessary.

2013-05-14EXYNOS5250/SNOW: fix the build script. Add a script to get the bl1.Ronald G. Minnich
build-snow got broken when the snow makefile improved. So fix it. While we're at it, create a script like the update-microcode scripts that gets the bl1. I thought about making this a common script but the various names and paths always evolve, leaving me thinking it's not worth it. This script is just a piece of the snow build script.

2013-05-14coreboot: add thread cooperative multitaskingAaron Durbin
The cooperative multitasking support allows the boot state machine to be ran cooperatively with other threads of work. The main thread still continues to run the boot state machine (src/lib/hardwaremain.c). All callbacks from the state machine are still ran synchronously from within the main thread's context. Without any other code added the only change to the boot sequence when cooperative multitasking is enabled is the queueing of an idlle thread. The idle thread is responsible for ensuring progress is made by calling timer callbacks. The main thread can yield to any other threads in the system. That means that anyone that spins up a thread must ensure no shared resources are used from 2 or more execution contexts. The support is originally intentioned to allow for long work itesm with busy loops to occur in parallel during a boot. Note that the intention on when to yield a thread will be on calls to udelay().

2013-05-14AMD Brazos/Trinity boards: PlatformGnbPcie.c: Reserve correct amount of memoryPaul Menzel

IN VOID *Reserved; ///< Reserved for future use } PCIe_COMPLEX_DESCRIPTOR; […] memory has to be reserved for the `PCIe_COMPLEX_DESCRIPTOR` and, as two struct members are pointers to arrays with elements of type `PCIe_PORT_DESCRIPTOR` and `PCIe_DDI_DESCRIPTOR`, space for these times the number of array elements have to be reserved: a + b * 5 + c * 2. sizeof(PCIe_COMPLEX_DESCRIPTOR) + sizeof(PCIe_PORT_DESCRIPTOR) * 5 + sizeof(PCIe_DDI_DESCRIPTOR) * 2; But for whatever reason parentheses were put in there making this calculation incorrect and reserving too much memory.

2013-05-10Get rid of MAXIMUM_CONSOLE_LOGLEVEL; compile all messages into the coreboot ↵Ronald G. Minnich
binary This option has never had much if any use. It solved a problem over 10 years ago that resulted from an argument over the value or lack thereof of including all the debug strings in a coreboot image. The answer is in: it's a good idea to maintain the capability to print all messages, for many reasons. This option is also misleading people, as in a recent discussion, to believe that log messges are controlled at build time in a way they are not. For the record, from this day forward, we can print messages at all log levels and the default log level is set at boot time, as directed by DEFAULT_CONSOLE_LOGLEVEL. You can set the default to 0 at build time and if you are having trouble override it in CMOS and get more messages. Besides, a quick glance shows it's always set to max (9 in this case) in the very few cases (1) in which it is set. Change-Id: I60c4cdaf4dcd318b841a6d6c70546417c5626f21 Signed-off-by: Ronald G.

Since the TSC udelay() function can be used in SMM that means the TSC can count up to whatever value. The current loop was not handling TSC rollover properly. In most cases this should not matter as the TSC typically starts ticking at value 0, and it would take a very long time to roll it over. However, it is my understanding that this behavior is not guaranteed. Theoretically the TSC could start or be be written to with a large value that would cause the rollover.

2013-05-07boot state: remove drain timers optionAaron Durbin
Internally there were states that had an attribute to indicate that the timers needed to be drained. Now that there is a way to block state transitions rely on this ability instead of draining timers. The timers will drain themselves when a state is blocked.

2013-05-07boot state: add ability to block state transitionsAaron Durbin
In order to properly sequence the boot state machine it's important that outside code can block the transition from one state to the next. When timers are not involved there's no reason for any of the existing code to block a state transition. However, if there is a timer callback that needs to complete by a certain point in the boot sequence it is necessary to place a block for the given state. To that end, 4 new functions are added to provide the API for blocking a state. 1. boot_state_block(boot_state_t state, boot_state_sequence_t seq); 2. boot_state_unblock(boot_state_t state, boot_state_sequence_t seq); 3. boot_state_current_block(void); 4. boot_state_current_unblock(void); Change-Id: Ieb37050ff652fd85a6b1e0e2f81a1a2807bab8e0 Signed-off-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: http://review.coreboot.org/3204 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>

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.
