6 Enable recording of boot time while booting. To use it, insert
7 calls to bootstage_mark() with a suitable BOOTSTAGE_ID from
8 bootstage.h. Only a single entry is recorded for each ID. You can
9 give the entry a name with bootstage_mark_name(). You can also
10 record elapsed time in a particular stage using bootstage_start()
11 before starting and bootstage_accum() when finished. Bootstage will
Robert P. J. Daye9c629c2016-08-31 12:49:13 -040012 add up all the accumulated time and report it.
Simon Glass5322d622015-03-02 17:04:37 -070013
14 Normally, IDs are defined in bootstage.h but a small number of
Robert P. J. Daye9c629c2016-08-31 12:49:13 -040015 additional 'user' IDs can be used by passing BOOTSTAGE_ID_ALLOC
Simon Glass5322d622015-03-02 17:04:37 -070016 as the ID.

85 has a 'name' property and either 'mark' containing the

108 the boot timing information in a binary format at a given address.
109 This happens through a call to bootstage_stash(), typically in

111 'bootstage stash' and 'bootstage unstash' commands to do this on
112 the command line.

867 bool "Include bounce buffer API"
868 help
869 Some peripherals support DMA from a subset of physically
870 addressable memory only. To support such peripherals, the
871 bounce buffer API uses a temporary buffer: it copies data
872 to/from DMA regions while managing cache operations.
873
874 A second possible use of bounce buffers is their ability to
875 provide aligned buffers for DMA operations.

890 With this option U-Boot will call arch_early_init_r() soon after
891 relocation. Driver model is running by this point, and the cache
892 is on. Note that board_early_init_r() is called first, if

906 Some boards need to perform initialisation as soon as possible
907 after boot. With this option, U-Boot calls board_early_init_f()
908 after driver model is ready in the pre-relocation init sequence.
909 Note that the normal serial console is not yet set up, but the
910 debug UART will be available if enabled.

923 is passed to the command-line interpreter (e.g. for initializations
924 that depend on later phases in the init sequence). With this option,
925 U-Boot calls last_stage_init() before the command-line interpreter is
926 started.
