initcall: Support manual relocation

2023-08-31T17:16:54+00:00

Move the manual-relocation code to the initcall file. Make sure to avoid
manually relocating event types. Only true function pointers should be
relocated.

initcall: Support emitting events

2023-08-31T17:16:54+00:00

At present the initcall list consists of a list of function pointers. Over
time the initcall lists will likely change to mostly emitting events,
since most of the calls are board- or arch-specific.

As a first step, allow an initcall to be an event type instead of a
function pointer. Add the required macro and update initcall_run_list() to
emit an event in that case, or ignore it if events are not enabled.

The bottom 8 bits of the function pointer are used to hold the event type,
with the rest being all ones. This should avoid any collision, since
initcalls should not be above 0xffffff00 in memory.

Convert misc_init_f over to use this mechanism.

Add comments to the initcall header file while we are here. Also fix up
the trace test to handle the change.

Revert "initcall: Move to inline function"

2023-08-31T17:16:54+00:00

Somehow I do not see any inlining with initcalls now. I was sure I saw
it when this commit went in, but now it seems to make things worse.

This reverts commit 47870afab92fca6e672c03d0dea802a55e200675.

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include  at all, so
remove that include.

initcall.h: initcall_run_list(): Improve debug output

2019-10-04T16:21:23+00:00

Existing debug output is mixed with the function name:
initcall_run_list() initcall: 25263initcall_run_list()  (relocated to 425263)

Turn it to:
initcall_run_list() initcall: 25263 (relocated to 425263)

initcall: Drop use of header files

2019-04-24T02:26:43+00:00

This file should not include header files. They have already been included
by the time initcall.h is included. Also, document how to enable debugging
in this file.

sandbox: Improve debugging in initcall_run_list()

2019-04-24T02:26:43+00:00

At present if one of the initcalls fails on sandbox the address printing
is not help, e.g.:

  initcall sequence 0000557678967c80 failed at call 00005576709dfe1f (err=-96)

This is because U-Boot gets relocated high into memory and the relocation
offset (gd->reloc_off) does not work correctly for sandbox.

Add support for finding the base address of the text region (at least on
Linux) and use that to set the relocation offset. This makes the output
better:

  initcall sequence 0000560775957c80 failed at call 0000000000048134 (err=-96)

Then you use can use grep to see which init call failed, e.g.:

   $ grep 0000000000048134 u-boot.map
   stdio_add_devices

Of course another option is to run it with a debugger such as gdb:

   $ gdb u-boot
   ...
   (gdb) br initcall.h:41
   Breakpoint 1 at 0x4db9d: initcall.h:41. (2 locations)

Note that two locations are reported, since this function is used in both
board_init_f() and board_init_r().
