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.

this.

sandbox: log: Add a category for sandbox

2018-11-21T02:14:22+00:00

It seems useful to make sandbox its own log category since it is used for
so much testing. Add this as a new category.

log: Add comments to the rest of the log categories

2018-10-09T10:40:27+00:00

At present some of the log categories are missing comments. Add them.

sandbox: spi: Add more logging

2018-10-09T10:40:27+00:00

Add logging to aid debugging features in these drivers. Also drop some
code in sandbox_spi_xfer() which is not used.

log: Add helpers for common log levels

2018-10-09T10:40:26+00:00

At present to output a log message you need something like:

   log(UCLASS_SPI, LOCL_INFO, "message1");
   log(UCLASS_SPI, LOCL_INFO, "message2");

but many files use the same category throughout. Also it is helpful to
shorten the length of log names, providing helpers for common logging
levels. Add some macros so that it is possible to do:

   (top of file, before #includes)
   #define LOG_CATEGORY UCLASS_SPI

   (later in the file)
   log_info("message1");
   log_debug("message2");
   log_err("message3");

log: Correct definition of log_msg_ret()

2018-10-08T14:30:22+00:00

This macro should have two parameters, not one. Fix it so that it
correctly resolves to _ret when logging is disabled.

log: Add a way to log a return value with a message

2018-07-09T15:11:00+00:00

It is sometimes useful to show a message when logging an error return
value, perhaps to add a few details about the problem. Add a function to
support this.

log: Fix incorect range check in log_get_cat_name()

This allows access to an element after the end of the array. Fix it.
