The 192k of RAM in the STM32F4 is not contiguous. There are actually three different banks, two of which share one memory range, and a third bank of CCM which is at a different address range. The memory map for the STM32F4 should begin:

  "  <memory type=\"rom\" start=\"0x00000000\" length=\"0x100000\"/>"       // code = sram, bootrom or flash; flash is bigger
  "  <memory type=\"ram\" start=\"0x10000000\" length=\"0x10000\"/>"        // ccmram
  "  <memory type=\"ram\" start=\"0x20000000\" length=\"0x20000\"/>"        // sram

Just replace the two lines starting with the first line quoted above with those three lines, that is the entire patch.
