2019-06-03src/device: Prevent attack on null pointer dereferenceJohn Zhao
Clang Static Analyzer version 8.0.0 detects access to field dev results in a dereference of a null pointer which is loaded from variable bus. Add sanity check for pointer bus to prevent null pointer dereference. TEST=Built and boot up to kernel.

2019-03-25Fix up remaining boolean uses of CONFIG_XXX to CONFIG(XXX)Julius Werner
This patch cleans up remaining uses of raw boolean Kconfig values I could find by wrapping them with CONFIG(). The remaining naked config value warnings in the code should all be false positives now (although the process was semi-manual and involved some eyeballing so I may have missed a few).

2013-11-26Clean up POST codes for Boot State machineDuncan Laurie
Now that there is a clearly defined boot state machine we can add some useful post codes to indicate the current point in the state machine by having it log a post code before the execution of each state. This removes the currently defined POST codes that were used by hardwaremain in favor of a new contiguous range that are defined for each boot state. The reason for this is that the existing codes are mostly used to indicate when something is done, which is confusing for actual debug because POST code debugging relies on knowing what is about to happen (to know what may be at fault) rather than what has just finished. One additonal change is added during device init step as this step often does the bulk of the work, and frequently logs POST codes itself. Therefore in order to keep better track of what device is being initialized POST_BS_DEV_INIT is logged before each device is initialized. interrupted boot with reset button and gathered the eventlog.

2013-11-26Log device path into CMOS during probe stagesDuncan Laurie
One of the most common hangs during coreboot execution is during ramstage device init steps. Currently there are a set of (somewhat misleading) post codes during this phase which give some indication as to where execution stopped, but it provides no information on what device was actually being initialized at that point. This uses the new CMOS "extra" log banks to store the encoded device path of the device that is about to be touched by coreboot. This way if the system hangs when talking to the device there will be some indication where to investigate next. interrupted boot with reset button and gathered the eventlog after several test runs: 26 | 2013-06-10 10:32:48 | System boot | 120 27 | 2013-06-10 10:32:48 | Last post code in previous boot | 0x75 | Device Initialize 28 | 2013-06-10 10:32:48 | Extra info from previous boot | PCI | 00:16.0 29 | 2013-06-10 10:32:48 | Reset Button 30 | 2013-06-10 10:32:48 | System Reset Change-Id: I6045bd4c384358b8a4e464eb03ccad639283939c Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/58105 Reviewed-on: http://review.coreboot.org/4230 Tested-by: build bot (Jenkins) Reviewed-by: Alexandru Gagniuc <mr.nuke.me@gmail.com>
2013-11-08Add new finalize functions for devices and chipsMarc Jones
Many chipset devices require additional configuration after device init. It is not uncommmon for a device early in the devicetree list to need to change a setting after a device later in the tree does PCI init. A final function call has been added to device ops to handle this case. It is called prior to coreboot table setup. Another problem that is often seen is that the chipset or mainboard need to do some final cleanup just before loading the OS. The chip finalize has been added for this case. It is call after all coreboot tables are setup and the payload is ready to be called. Similar functionality could be implemented with the hardwaremain states, but those don't fit well in the device tree function pointer structure and should be used sparingly.
