There are a lot of unrelated files in common, including all of the commands. Moving them into their own directory makes them easier to find and is more logical. Some commands include non-command code, such as cmd_scsi.c. This should be sorted out at some point so that the function can be enabled with or without the associated command. Unfortunately, with m68k I get this error: m68k: + M5329AFEE +arch/m68k/cpu/mcf532x/start.o: In function `_start': +arch/m68k/cpu/mcf532x/start.S:159:(.text+0x452): relocation truncated to fit: R_68K_PC16 against symbol `board_init_f' defined in .text.board_init_f section in common/built-in.o I hope someone can shed some light on what this means. I hope it isn't depending on the position of code in the image.

help
|
|
Enable recording of boot time while booting. To use it, insert
|
|
calls to bootstage_mark() with a suitable BOOTSTAGE_ID from
|
|
bootstage.h. Only a single entry is recorded for each ID. You can
|
|
give the entry a name with bootstage_mark_name(). You can also
|
|
record elapsed time in a particular stage using bootstage_start()
|
|
before starting and bootstage_accum() when finished. Bootstage will
|
|
add up all the accumated time and report it.
|
|
|
|
Normally, IDs are defined in bootstage.h but a small number of
|
|
additional 'user' IDs can be used but passing BOOTSTAGE_ID_ALLOC
|
|
as the ID.
|
|
|
|
Calls to show_boot_progress() wil also result in log entries but
|
|
these will not have names.

This is the number of available user bootstage records.

Each time you call bootstage_mark(BOOTSTAGE_ID_ALLOC, ...)

a new ID will be allocated from this stash. If you exceed

the limit, recording will stop.

|
|
help
|
|
Stash the bootstage information in the FDT. A root 'bootstage'
|
|
node is created with each bootstage id as a child. Each child
|
|
has a 'name' property and either 'mark' containing the
|
|
mark time in microsecond, or 'accum' containing the
|
|
accumulated time for that bootstage id in microseconds.
|
|
For example:
|
|
|
|
bootstage {
|
|
154 {
|
|
name = "board_init_f";
|
|
mark = <3575678>;
|
|
};
|
|
170 {
|
|
name = "lcd";
|
|
accum = <33482>;
|
|
};
|
|
};
|
|
|
|
Code in the Linux kernel can find this in /proc/devicetree.

config BOOTSTAGE_STASH

bool "Stash the boot timing information in memory before booting OS"

depends on BOOTSTAGE
|
|
help
|
|
Some OSes do not support device tree. Bootstage can instead write
|
|
the boot timing information in a binary format at a given address.
|
|
This happens through a call to bootstage_stash(), typically in
|
|
the CPU's cleanup_before_linux() function. You can use the
|
|
'bootstage stash' and 'bootstage unstash' commands to do this on
|
|
the command line.

config CONSOLE_RECORD

help
|
|
This provides a way to record console output (and provide console
|
|
input) through cirular buffers. This is mostly useful for testing.
|

Console output is recorded even when the console is silent.

To enable console recording, call console_record_reset_enable()
|
|
from your code.
