+	  The Common Flash Interface specification was developed by Intel,
+	  AMD and other flash manufactures that provides a universal method
+	  for probing the capabilities of flash devices. If you wish to
+	  support any device that is CFI-compliant, you need to enable this
+	  option. Visit <https://www.amd.com/products/nvd/overview/cfi.html>

+	  compatible with the Common Flash Interface, but will use the common
+	  CFI-targeted flash drivers for any chips which are identified which
+	  are in fact compatible in all but the probe method. This actually

+	help
+	  This enables support for reading, writing and locking so called
+	  "Protection Registers" present on some flash chips.
+	  A subset of them are pre-programmed at the factory with a
+	  unique set of values. The rest is user-programmable.
+
+	  The user-programmable Protection Registers contain one-time
+	  programmable (OTP) bits; when programmed, register bits cannot be
+	  erased. Each Protection Register can be accessed multiple times to
+	  program individual bits, as long as the register remains unlocked.
+
+	  Each Protection Register has an associated Lock Register bit. When a
+	  Lock Register bit is programmed, the associated Protection Register
+	  can only be read; it can no longer be programmed. Additionally,
+	  because the Lock Register bits themselves are OTP, when programmed,
+	  Lock Register bits cannot be erased. Therefore, when a Protection
+	  Register is locked, it cannot be unlocked.
+
+	  This feature should therefore be used with extreme care. Any mistake
+	  in the programming of OTP bits will waste them.
