Summary of changes

FLASH_SIZE incorrectly reports flash size for cat.3 devices with DEV_ID 0x436.

STM32L1 Reference Manual RM0038:

31.1.1 Flash size register
F_SIZE: Flash memory size
For DEV_ID = 0x416 or 0x427 or 0x429 or 0x437, this field value indicates the Flash memory size of the device in Kbytes.
Example: 0x0080 = 128 Kbytes.
For DEV_ID = 0x436, the field value can be ‘0’ or ‘1’, with ‘0’ for 384 Kbytes and ‘1’ for 256 Kbytes.
