+@deffn Command {flash erase_address} [@option{pad}] [@option{unlock}] address length
Erase sectors starting at @var{address} for @var{length} bytes.
Unless @option{pad} is specified, @math{address} must begin a
flash sector, and @math{address + length - 1} must end a sector.
the specified length must stay within that bank.
As a special case, when @var{length} is zero and @var{address} is
the start of the bank, the whole flash is erased.
+If @option{unlock} is specified, then the flash is unprotected
+before erase starts.
@end deffn

Print info about flash bank @var{num}
The @var{num} parameter is a value shown by @command{flash banks}.
-The information includes per-sector protect status, which may be
-incorrect (outdated) unless you first issue a
-@command{flash protect_check num} command.
+This command will first query the hardware, it does not print cached

-This updates the protection information displayed by @option{flash info}.

@section Flash Driver List
As noted above, the @command{flash bank} command requires a driver name,

@end deffn
+@deffn {Flash Driver} virtual
+This is a special driver that maps a previously defined bank to another
+address. All bank settings will be copied from the master physical bank.
+
+The @var{virtual} driver defines one mandatory parameters,
+
+@itemize
+@item @var{master_bank} The bank that this virtual address refers to.
+@end itemize
+
+So in the following example addresses 0xbfc00000 and 0x9fc00000 refer to
+the flash bank defined at address 0x1fc00000. Any cmds executed on
+the virtual banks are actually performed on the physical banks.
+@example
+flash bank $_FLASHNAME pic32mx 0x1fc00000 0 0 0 $_TARGETNAME
+flash bank vbank0 virtual 0xbfc00000 0 0 0 $_TARGETNAME $_FLASHNAME
+flash bank vbank1 virtual 0x9fc00000 0 0 0 $_TARGETNAME $_FLASHNAME
