RTC fast memory segment to free the slow memory region for ULP programs.

If this option is disabled, the DRAM part of the heap starts right after the .bss section,

within the dram0_0 region. As a result, adding or removing some static variables

will change the available heap size.

RAM size dedicated for static variables (.data & .bss sections).

This value is less than the chips total memory, as not all of it can be used for this purpose.

E.g. parts are used by the software bootloader, and will only be available
|
|
as heap memory after app startup.
