The wkup_r5fss0_core0_memory_region was reserved with only
0x0f00000 but the MCU SDK linker for the wkup R5F firmware on
AM62P defines the DM code/data DDR footprint differently:
/* DDR for DM R5F code/data [ size 27 MiB + 396 KB ] */
DDR : ORIGIN = 0x9CAA5000 LENGTH = 0x1B63000
which results in an end at 0x9e608000. For this memory region which
starts at 0x9c900000 this means a length of:
0x9e608000 - 0x9c900000 = 0x1d08000
