Review Comment:
   The `check` job fails here: cmake-format wants one blank line after the 
license, and there are two.
   
   Fix: delete line 23.

Review Comment:
   `SRAM1_END` 0x2001c000 includes the CCM alias at 0x20018000-0x2001bfff (see 
the comment in scripts/ld.script), and `SRAM2` at 0x10000000 is the same 16 
KiB. With `CONFIG_MM_REGIONS=2` the heap gets that memory twice; the ld.script 
comment also says that CCM stays reserved.
   
   Fix: set `SRAM1_END` to 0x20018000.
