choice BT_NIMBLE_MEM_ALLOC_MODE
prompt "Memory allocation strategy"
default BT_NIMBLE_MEM_ALLOC_MODE_INTERNAL
help
Allocation strategy for NimBLE host stack, essentially provides ability to
allocate all required dynamic allocations from,
- Internal DRAM memory only
- External SPIRAM memory only
- Either internal or external memory based on default malloc()
behavior in ESP-IDF
- Internal IRAM memory wherever applicable else internal DRAM
Recommended mode here is always internal, since that is most preferred
from security perspective. But if application requirement does not
allow sufficient free internal memory then alternate mode can be
selected.

Allows to use IRAM memory region as 8bit accessible region.
Every unaligned (8bit or 16bit) access will result in an exception
and incur penalty of certain clock cycles per unaligned read/write.
