+	  On some platforms where no separate I/O space exists, there are I/O
+	  hosts which can not be accessed in MMIO mode. Using the logical PIO
+	  mechanism, the host-local I/O resource can be mapped into system
+	  logic PIO space shared with MMIO hosts, such as PCI/PCIe, then the
+	  system can access the I/O devices with the mapped-logic PIO through
+	  I/O accessors.
+
+	  This way has relatively little I/O performance cost. Please make

+	help
+	  Drivers may select this option to force specific constant

+	  (error correction capability). Those specific values must
+	  be set by declaring default values for symbols BCH_CONST_M
+	  and BCH_CONST_T.
+	  Doing so will enable extra compiler optimizations,
+	  improving encoding and decoding performance up to 2x for
+	  usual (m,t) values (typically such that m*t < 200).
+	  When this option is selected, the BCH library supports
+	  only a single (m,t) configuration. This is mainly useful
+	  for NAND flash board drivers requiring known, fixed BCH
+	  parameters.
+

+	help
+	  This option provides a glob_match function for performing
+	  simple text pattern matching.  It originated in the ATA code
+	  to blacklist particular drive models, but other device drivers
+	  may need similar functionality.
+
+	  All drivers in the Linux kernel tree that require this function

+	  This option enables a simple self-test of the glob_match

+	  working on the code to ensure they haven't introduced any

+
+	  It only adds a little bit of code and slows kernel boot (or
+	  module load) by a small amount, so you're welcome to play with
+	  it, but you probably don't need it.
