This patch enables memory leak detection in bget_malloc.c.
This is very helpful to find memory leakage issue in teecore
or user TA. To enable it in teecore, build optee_os with
`CFG_TEE_CORE_MALLOC_DEBUG=y`. For user TA, build optee_os
with `CFG_TEE_TA_MALLOC_DEBUG=y`.
Then, add the following statement at some point of your
code that might frequently been triggered:
mdbg_check(1);
It will dump allocated memory blocks and the holders of
them. If you find a memory block appears multiple times
after the system runs a period of time, it is very likely
the source of memory leakage.
Here is an example output:
