# Note: Regarding the build option: LOG_LEVEL.
# There seems to be an issue when setting it
# to 50 (LOG_LEVEL_VERBOSE), where the kernel
# tee driver sends yielding requests to OP-TEE
# at a faster pace than OP-TEE processes them,
# as the processing time is consumed by logging
# in TF-A. When this issue occurs, booting halts
# as soon as optee driver starts initialization.
# Therefore, it's not currently recommended to
# set LOG_LEVEL to 50 at all.
