config BOARD

string

help
|
|
This option holds the name of the board and is used to locate the files
|
|
related to the board in the source tree (under boards/).
|
|
The Board is the first location where we search for a linker.ld file,
|
|
if not found we look for the linker file in
|
|
soc/<arch>/<family>/<series>

config BOARD_REVISION

|
|
help
|
|
If the BOARD has a revision field set, this is the revision.
|
|
Otherwise, it is the empty string. For example, if BOARD is
|
|
"plank@foo", this option will be "foo". If BOARD is "plank",
|
|
this option will be the empty string.

This hidden option is set in the board configuration and indicates

the Zephyr release that the board configuration will be removed.

When set, any build for that board will generate a clearly visible

deprecation warning.

When the virtual CPU is sleeping, the virtual time will advance
|

at default speed unless this option is set. With this option set,
|
|
the virtual time will jump to the next timer deadline instantly
|
|
whenever the virtual CPU goes to sleep mode and will not advance

|
if no timer is enabled. This behavior gives deterministic execution
|

times from the guest point of view.
