+@cindex Common Flash Interface
+@cindex CFI
+The ``Common Flash Interface'' (CFI) is the main standard for
+external NOR flash chips, each of which connects to a
+specific external chip select on the CPU.
+Frequently the first such chip is used to boot the system.
+Your board's @code{reset-init} handler might need to
+configure additional chip selects using other commands (like: @command{mww} to
+configure a bus and its timings) , or
perhaps configure a GPIO pin that controls the ``write protect'' pin
on the flash chip.
+The CFI driver can use a target-specific working area to significantly
+speed up operation.

-<@var{target}> [@var{jedec_probe}|@var{x16_as_x8}]
-@*CFI flashes require the name or number of the target they're connected to
-as an additional
-argument. The CFI driver makes use of a working area (specified for the target)
-to significantly speed up operation.
+The CFI driver can accept the following optional parameters, in any order:
-@var{chip_width} and @var{bus_width} are specified in bytes.
+@itemize
+@item @var{jedec_probe} ... is used to detect certain non-CFI flash ROMs,
+like AM29LV010 and similar types.

-The @var{jedec_probe} option is used to detect certain non-CFI flash ROMs, like AM29LV010 and similar types.
+To configure two adjacent banks of 16 MBytes each, both sixteen bits (two bytes)
+wide on a sixteen bit bus:
-@var{x16_as_x8} ???

+flash bank cfi 0x00000000 0x01000000 2 2 $_TARGETNAME

+<@var{offset}> bytes from the beginning of the bank.
+@item @b{mflash dump} <@var{num}> <@var{file}> <@var{offset}> <@var{size}>
+@cindex mflash dump
+@*Dump <size> bytes, starting at <@var{offset}> bytes from the beginning of the <@var{num}> bank
+to a <@var{file}>.
+@item @b{mflash config pll} <@var{frequency}>
+@cindex mflash config pll
+@*Configure mflash pll. <@var{frequency}> is input frequency of mflash. The order is Hz.
+Issuing this command will erase mflash's whole internal nand and write new pll.
+After this command, mflash needs power-on-reset for normal operation.
+If pll was newly configured, storage and boot(optional) info also need to be update.
+@item @b{mflash config boot}
+@cindex mflash config boot
+@*Configure bootable option. If bootable option is set, mflash offer the first 8 sectors
+(4kB) for boot.
+@item @b{mflash config storage}
+@cindex mflash config storage
+@*Configure storage information. For the normal storage operation, this information must be
+written.

Erases blocks on the specified NAND device, starting at the
specified @var{offset} and continuing for @var{length} bytes.
Both of those values must be exact multiples of the device's

@cindex NAND writing
+@cindex NAND programming
Writes binary data from the file into the specified NAND device,
starting at the specified offset. Those pages should already

As noted above, the @command{nand device} command allows
driver-specific options and behaviors.
@deffn {NAND Driver} lpc3180
These controllers require an extra @command{nand device}
parameter: the clock rate used by the controller.
-@deffn Command {nand lpc3180 select} num [mlc|slc]
+@deffn Command {lpc3180 select} num [mlc|slc]
Configures use of the MLC or SLC controller mode.
MLC implies use of hardware ECC.
The @var{num} parameter is the value shown by @command{nand list}.
