+Enables or disables autoerase mode for a flash bank.

+If flash_autoerase is off, use mass_erase before flash programming.
+Flash erase command fails if region to erase is not whole flash memory.
+
+If flash_autoerase is on, a sector is both erased and programmed in one
+system ROM call. Flash erase command is ignored.
+This mode is suitable for gdb load.
