bootflow boot
-
+ bootflow cmdline [set|get|clear|delete|auto] <param> [<value>]
Description
-----------
This boots the current bootflow.
+bootflow cmdline
+~~~~~~~~~~~~~~~~
+
+Some bootmeths can obtain the OS command line since it is stored with the OS.
+In that case, you can use `bootflow cmdline` to adjust this. The command line
+is assumed to be in the format used by Linux, i.e. a space-separated set of
+parameters with optional values, e.g. "noinitrd console=/dev/tty0".
+
+To change or add a parameter, use::
+
+ bootflow cmdline set <param> <value>
+
+To clear a parameter value to empty you can use "" for the value, or use::
+
+ bootflow cmdline clear <param>
+
+To delete a parameter entirely, use::
+
+ bootflow cmdline delete <param>
+
+Automatic parameters are available in a very few cases. You can use these to
+add parmeters where the value is known by U-Boot. For example::
+
+ bootflow cmdline auto earlycon
+ bootflow cmdline auto console
+
+can be used to set the early console (or console) to a suitable value so that
+output appears on the serial port. This is only supported by the 16550 serial
+driver so far.

+
+Description
+-----------
+
+The *mtrr* command is used to dump the Memory Type Range Registers (MTRRs) on
+an x86 machine. These register control cache behaviour in selected memory
+ranges.
+
+Note that the number of registers can vary between CPUs.
+
+
+mtrr [list]
+~~~~~~~~~~~
+
+List the MTRRs. The table shows the following information:
+
+Reg
+ Register number (the first is register 0)
+
+Valid
+ Shows Y if the register is valid (has bit 11 set), N if not
+
+Write-type
+ Shows the behaviour when writing to the memory region. The types are
+ abbreviated to fit a reasonable line length. Valid types shown below.
+
+ ====== ============== ====================================================
+ Value Type Meaning
+ ====== ============== ====================================================
+ 0 Uncacheable Skip cache and write directly to memory
+ 1 Combine Multiple writes can be combined into one transaction
+ 4 Through Update cache and also write to memory
+ 5 Protect Writes are prohibited
+ 6 Back Update cache but don't write to memory
+ ====== ============== ====================================================
+
+Base
+ Base memory address from which the register controls behaviour
+
+Mask
+ Mask value, which also indicates the size
+
+Size
+ Length of memory region within which the register controls behaviour
+
+
+mtrr set
+~~~~~~~~
+
+This sets the value of a particular MTRR. Parameters are:
+
+reg
+ Register number to set, with 0 being the first
+
+type
+ Access type to set. See Write-type above for valid types. This uses the name
+ rather than its numeric value.
+
+start
+ Base memory address from which the register should control behaviour
+
+size
+ Length of memory region within which the register controls behaviour
+
+
+mtrr disable
+~~~~~~~~~~~~
+
+This disables a particular register, by clearing its `valid` bit (11).
+
+
+mtrr enable
+~~~~~~~~~~~
+
+This enables a particular register, by setting its `valid` bit (11).
+
+
+Example
+-------
+
+This shows disabling and enabling an MTRR, as well as setting its type::
