Describe the solution you'd like

• Use sys_get_le24() to pass crc_init value
• Define CRC polynomial and use the define instead of magic numbers.

In PROTECTED mode, the MPU is used to map regions of memory to supervisor- and/or user-accessible memory. Currently, that algorithm is very simple: The entire address range is made accessible in supervisor mode; a single MPU region is used to enable user-mode access in each user memory region.

Each MPU region must bit both of a power-of-two size and with an alignment in memory equal to the si

With aligned_alloc() in the C11 standard, free() is called to free memory, rather than an equivalent aligned_free().

We should update our library with some logic that can be used to correctly call aligned_free() if free() is used instead.
