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.

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>

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.
