dm: devres: Convert to use logging

2020-01-07T23:02:38+00:00

At present when CONFIG_DEBUG_DEVRES is enabled, U-Boot prints log messages
to the console with every devres allocation/free event. This causes most
tests to fail since the console output is not as expected.

In particular this prevents us from adding a device to sandbox which uses
devres in its bind method.

Move devres over to use U-Boot's logging feature instead, and add a new
category for devres.

common: Add a noisy assert()

2020-01-07T23:02:38+00:00

Some U-Boot code uses BUG_ON() and WARN_ON() macros. These use __FILE__
which can include quite a large path, depending on how U-Boot is built.

The existing assert() is only checked if DEBUG is enabled. Add a new one
which is always checked, and prints a (smaller) error in that case.

log: Add log_nop() to avoid unused-variable warnings

2019-10-08T05:57:44+00:00

If a log statement includes a variable and logging is disabled, this can
generate warnings about unused variables. Add a bit more complexity to the
macros to avoid this for the common case.

log: document the assign() macro

2019-08-07T19:31:02+00:00

Provide a concise description of the assert() macro. Point out that the
tested expression is always executed, irrespective of the value of _DEBUG.

log: Allow #define LOG_DEBUG to enable logging in a file

2019-02-20T07:21:44+00:00

At present it is possible to '#define DEBUG' at the top of a file which
causes all debug() statements in that file to become active. There is
currently no equivalent with logging, but this is a useful function.

Add a LOG_DEBUG define along with documentation.

log: Fix up Kconfig log level names

2019-02-20T07:21:44+00:00

The log level numbers in the Kconfig are not actually correct. Fix them
and also add a missing space in the header-file comment.

log: Check printf() arguments

At present logging does not check printf() arguments. Now that all users
have been corrected, enable this to prevent further problems.

malloc_simple: Add logging of allocations

2018-11-29T16:30:05+00:00

It is sometimes useful to see what memory is being allocated early during
boot. Add logging to support this, using a new LOGC_ALLOC category.

Add core support for a bloblist to convey data from SPL

2018-11-26T13:25:32+00:00

At present there is no standard way in U-Boot to pass information from SPL
to U-Boot proper. But sometimes SPL wants to convey information to U-Boot
that U-Boot cannot easily figure out. For example, if SPL sets up SDRAM
then it might want to pass the size of SDRAM, or the location of each
bank, to U-Boot proper.

Add a new 'bloblist' feature which provides this. A bloblist is set up in
the first phase of U-Boot that runs (i.e. TPL or SPL). The location of
this info may be in SRAM or CAR (x86 cache-as-RAM) or somewhere else.

Information placed in this region is preserved (with a checksum) through
TPL and SPL and ends up in U-Boot. At this point it is copied into SDRAM
so it can be used after relocation.
