/* The on-chip SRAM is split into SRAM_L and SRAM_U regions that form a

* contiguous block in the memory map, however misaligned accesses
|
|
* across the 0x2000_0000 boundary are not supported in the Arm

* Cortex-M4 architecture. For clarity and to avoid the temptation for
|
|
* someone to extend sram0 without solving this issue, we define two

* separate memory nodes here and only use the upper one for now. A
