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. Day57247d92016-08-31 12:49:13 -040015 additional 'user' IDs can be used by passing BOOTSTAGE_ID_ALLOC
Simon Glassee2b2432015-03-02 17:04:37 -070016 as the ID.

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

873 require once the actual init done, example saving board specific env,
874 boot-modes etc. which eventually done at late.
875

903 bool "Include bounce buffer API"
904 help
905 Some peripherals support DMA from a subset of physically
906 addressable memory only. To support such peripherals, the
907 bounce buffer API uses a temporary buffer: it copies data
908 to/from DMA regions while managing cache operations.
909
910 A second possible use of bounce buffers is their ability to
911 provide aligned buffers for DMA operations.
