[Qemu-devel] [PATCH v2 8/8] i.MX: Standardize i.MX GPT debug

[Jean-Christophe Dubois]

The goal is to have debug code always compiled during build.

We standardize all debug output on the following format:

[QOM_TYPE_NAME]reporting_function: debug message

We also replace IPRINTF with qemu_log_mask(). The qemu_log_mask() output
is following the same format as the above debug.

Signed-off-by: Jean-Christophe Dubois <j...@tribudubois.net>

Changes since v1:
 * standardize qemu_log_mask on same model.
