Before relocation, memory is very limited on many platforms. Still,
When disabling this, please check if malloc calls, maybe
should be replaced by calloc - if one expects zeroed memory.

+ It may happen that one needs to move the dynamic allocation
+ from one to another memory range, eg. when moving the malloc
+ from the limited static to a potentially large dynamic (DDR)
+ memory.
+
+ If so then on top of setting the updated memory aside one
+ needs to bring the malloc init.

+ If such a scenario is sought choose yes.

SHA256 checksum is a 256-bit (32-byte) hash value used to check that
- the image contents have not been corrupted. SHA256 is recommended
- for use in secure applications since (as at 2016) there is no known
- feasible attack that could produce a 'collision' with differing
- input data. Use this for the highest security. Note that only the
- SHA256 variant is supported: SHA512 and others are not currently
