+# On the STM32F7, the Flash is mapped at address 0x08000000 via the AXI and
+# also address 0x00200000 via the ITCM. The former mapping is read-write in
+# hardware, while the latter is read-only. By presenting an alias, we
+# accomplish two things:
+# (1) We allow writing at 0x00200000 (because the alias acts identically to the
+#     original bank), which allows code intended to run from that address to
+#     also be linked for loading at that address, simplifying linking.
+# (2) We allow the proper memory map to be delivered to GDB, which will cause
+#     it to use hardware breakpoints at the 0x00200000 mapping (correctly
+#     identifying it as Flash), which it would otherwise not do. Configuring
