Yes, it's possible to add more (p)SRAM via the STM32F10xxx's FSMC (flexible
static memory controller). The new memory is mapped to FSMC bank 1 at
0x6000_0000, though (as opposed to the embedded SRAM's fixed address at
0x2000_0000), as I have now realized. I'm happy to send an updated patch so
that "-m mem_size" creates a memory subregion at 0x6000_0000 instead.

Best regards,
Lucas
