bootstage: Warning if space is exhausted

2021-03-27T02:04:31+00:00

At present bootstage silently ignores new records if it runs out of
space. It is sometimes obvious by looking at the report, but the IDs are
not contiguous, so it is easy to miss.

Aad a message so that action can be taken.

bootstage: Fix dependency for BOOTSTAGE_RECORD_COUNT

2021-03-04T02:17:25+00:00

At present these three Kconfigs exist even when bootstage is not enabled.
This is not necessary since bootstage.c is only built if BOOTSTAGE is
enabled.

Make them conditional. Also fix up the overflow message to mention TPL.

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.

common: Drop bootstage.h from common header

Move this fairly uncommon header out of the common header.

common: Move hang() to the same header as panic()

2020-01-17T22:53:40+00:00

At present panic() is in the vsprintf.h header file. That does not seem
like an obvious choice for hang(), even though it relates to panic(). So
let's put hang() in its own header.

common: Move sorting functions to their own header file

2019-12-02T23:23:08+00:00

These don't need to be in common.h so move them out into a new header.
Also add some missing comments.

bootstage: Correct relocation algorithm

2019-10-27T16:56:51+00:00

At present bootstage relocation assumes that it is possible to point back
to memory available before relocation, so it does not relocate the
strings. However this is not the case on some platforms, such as x86 which
uses the cache as RAM and loses access to this when the cache is enabled.

Move the relocation step to before U-Boot relocates, expand the allocated
region to include space for the strings and relocate the strings at the
same time as the bootstage records.

This ensures that bootstage data can remain accessible from TPL through
SPL to U-Boot before/after relocation.

bootstage: Avoid conflicts between stash/unstash

2019-10-27T16:56:51+00:00

At present there is a single shared address for bootstage data in both
TPL and SPL. If SPL unstashs TPL bootstage info and then stashes it again
to pass it to U-Boot, the new stash overwrites the strings of the old
stash.

Fix this by duplicating the strings into the malloc() region. This should
be a small code. Fix the header-file order at the same time.

This problem doesn't happen at the next stage (SPL->U-Boot) since U-Boot
relocates the boostage data.

bootstage: Fix counting of entries in stash

2019-10-27T16:56:51+00:00

The current code searches for empty records but these not existing with
bootstage now. This used to be needed when bootstage records were stored
in a spare array.

Drop the unnecessary code and fix a code-style nit at the same time.
