+# Flash base address is known by driver. Flash size will be probed.

+# Please note that the larger stm32lx targets (256Kb and 384Kb) uses dual
+# bank flash. For such targets use target/stm32lx_dual_bank.cfg.

+# Some samples of ST's stm32lx chips are known to have incorrect flash size
+# values programmed in their FLASH_SIZE register. The driver will warn
+# for strange values. It is possible to override the flash size probe by
+# defining the correct size here. Notice though that it is the size of
+# the flash bank
