/* 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
* potential solution has been proposed in binutils:
* https://sourceware.org/ml/binutils/2017-02/msg00250.html
