gmtime_r() has been in the minimal libc for years, however it was not added to expcetions due to an overlook. In order to do this however, it has to be moved first to the common libc area, so that it's available to any libc that may not implement it. Signed-off-by: Robert Lubos <robert.lubos@nordicsemi.no>

Indicate the size in bytes of the memory arena used for

common C library malloc() implementation.

If set to zero, then no malloc() heap will be available.
|
|
|
|
If set to -1, then all remaining system RAM will be used for this
|
|
area.
|
|
|
|
If user mode is enabled, and MPU hardware has requirements that
|
|
regions be sized to a power of two and aligned to their size,
|
|
then this must be defined as a power of two or a compile error
|
|
will result.

When using the minimal C library, the default is to have no
|
|
malloc heap. Otherwise, on systems with an MMU the default is
|
|
16kB and all other systems will default to using all remaining
|
|
ram for the malloc heap.
