2013-05-07x86: harden tsc udelay() functionAaron Durbin
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: 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.

2013-05-01AMD Hudson A55E: Remove GEC firmware blob kconfig promptBruce Griffith
The "gigabit ethernet controller" (GEC) block was added to AMD Hudson A55E to integrate ethernet capabilities into an AMD southbridge. The GEC is designed to work with B50610 and B50610M gigabit PHY chips from Broadcom. These parts may not be generally available in small quantities for embedded development. The GEC block requires an opaque firmware blob to function. The GEC blob is controlled by AMD and Broadcom and is not available from coreboot.org. This change removes GEC support from AMD Parmer and AMD Thatcher mainboards since these boards do not have the Broadcom PHY. AMD has requested that the GEC be hidden for Hudson FCH since the PHY parts are not generally available. This Kconfig option can make it appear that this is a viable and supported way to add Ethernet to an embedded board. It is possible to use the Hudson GEC block with other PHYs, but this requires development of a custom GEC blob and a custom Ethernet driver. A custom GEC blob has been developed for a Micrel PHY, but there is no accompanying driver.

2013-05-01boot state: run timers on state entryAaron Durbin
When TIMER_QUEUE is configured on call the timer callbacks on entry into a state but before its entry callbacks. In addition provide a barrier to the following states so that timers are drained before proceeding. This allows for blocking state traversal for key components of boot. BS_OS_RESUME BS_WRITE_TABLES BS_PAYLOAD_LOAD BS_PAYLOAD_BOOT Future functionality consists of evaluating the timer callbacks within the device tree. One example is dev_initialize() as that seems state seems to take 90% of the boot time. The timer callbacks could then be ran in a more granular manner.

2013-05-01boot state: rebalance payload load vs actual bootAaron Durbin
The notion of loading a payload in the current boot state machine isn't actually loading the payload. The reason is that cbfs is just walked to find the payload. The actual loading and booting were occuring in selfboot(). Change this balance so that loading occurs in one function and actual booting happens in another. This allows for ample opportunity to delay work until just before booting.
