[PATCH v4 0/2] log: Allow multiple lines and conversion to printf()

[Simon Glass]

At present when logging is not enabled, all log() calls become nops. This
does not seem right, since if the log level is high enough then there
should be some sort of message. So in that case, this series updates it to
print the message if the log level is above LOGL_INFO.

This mimics the behaviour for the log_...() macros like log_debug() and
log_info(), so we can drop the special case for these.

Also the current implementation does not support multiple log calls on the
same line nicely. The tags are repeated so the line is very hard to read.
This series adds that as a new feature.

Changes in v4:
- Fix missing header for SPL

Changes in v3:
- Rebase on hexdump series

Changes in v2:
- Update commit message and cover letter to mention log_...() macros
- Add a test for !CONFIG_LOG
- Update log() to (effectively) call debug() for log_level == LOGL_DEBUG

Simon Glass (2):
  sandbox: log: Avoid build error with !CONFIG_LOG
  log: Convert log values to printf() if not enabled
