2021-06-14lib/hardwaremain.c: Hide preprocessor guards in headerAngel Pons
The `location` member of `struct boot_state_callback` is conditionally guarded depending on `CONFIG(DEBUG_BOOT_STATE)` using preprocessor. It is probably intended to save some space when the `location` strings do not get printed. However, directly using the `location` member without any guards will cause a compile-time error. Plus, preprocessor-guarded code gets nasty really quickly. In order to minimise preprocessor usage, introduce the `bscb_location` inline helper function, which transforms the compile-time error into a link-time error. It is then possible to substitute preprocessor guards with an ordinary C `if` statement.

They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2016-12-08bootstate: add arch specific hook at coreboot exitAaron Durbin
The bootstate machine allows one to schedule work at the boundaries of each state. However, there are no priorities by design. As such if there are things that need to be performed that are interdependent between callbacks there's no way to do that aside from explicitly putting the call in one of the callbacks. This situation arises around BS_OS_RESUME, BS_PAYLOAD_LOAD, and BS_PAYLOAD_BOOT as those are the states where coreboot is about to exit. As such, provide an architecture specific hook at these key places so that one is guaranteed any work done in arch_bootstate_coreboot_exit() is after all callbacks in the state machine.

2015-03-18bootstate: use structure pointers for scheduling callbacksAaron Durbin
The GCC 4.9.2 update showed that the boot_state_init_entry structures were being padded and assumed to be aligned in to an increased size. The bootstate scheduler for static entries, boot_state_schedule_static_entries(), was then calculating the wrong values within the array. To fix this just use a pointer to the boot_state_init_entry structure that needs to be scheduled. In addition to the previous issue noted above, the .bs_init section was sitting in the read only portion of the image while the fields within it need to be writable. Also, the boot_state_schedule_static_entries() was using symbol comparison to terminate a loop which in C can lead the compiler to always evaluate the loop at least once since the language spec indicates no 2 symbols can be the same value.

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>

2013-05-01ramstage: introduce boot state machineAaron Durbin
The boot flow currently has a fixed ordering. The ordering is dictated by the device tree and on x86 the PCI device ordering for when actions are performed. Many of the new machines and configurations have dependencies that do not follow the device ordering. In order to be more flexible the concept of a boot state machine is introduced. At the boundaries (entry and exit) of each state there is opportunity to run callbacks. This ability allows one to schedule actions to be performed without adding board-specific code to the shared boot flow.
