+@anchor{The init_board procedure}
+@subsection The init_board procedure
+@cindex init_board procedure
+
+The concept of @code{init_board} procedure is very similar to @code{init_targets} (@xref{The init_targets procedure}.)
+- it's a replacement of ``linear'' configuration scripts. This procedure is meant to be executed when OpenOCD enters run
+stage (@xref{Entering the Run Stage},) after @code{init_targets}. The idea to have spearate @code{init_targets} and
+@code{init_board} procedures is to allow the first one to configure everything target specific (internal flash,
+internal RAM, etc.) and the second one to configure everything board specific (reset signals, chip frequency,
+reset-init event handler, external memory, etc.). Additionally ``linear'' board config file will most likely fail when
+target config file uses @code{init_targets} scheme (``linear'' script is executed before @code{init} and
+@code{init_targets} - after), so separating these two configuration stages is very convenient, as the easiest way to
+overcome this problem is to convert board config file to use @code{init_board} procedure. Board config scripts don't
+need to override @code{init_targets} defined in target config files when they only need to to add some specifics.
+
+Just as @code{init_targets}, the @code{init_board} procedure can be overriden by ``next level'' script (which sources
+the original), allowing greater code reuse.
+
+@example
+### board_file.cfg ###
+
+# source target file that does most of the config in init_targets
+source [find target/target.cfg]
+
+proc enable_fast_clock @{@} @{
+ # enables fast on-board clock source
+ # configures the chip to use it

+@anchor{The init_targets procedure}
+@subsection The init_targets procedure
+@cindex init_targets procedure
+
+Target config files can either be ``linear'' (script executed line-by-line when parsed in configuration stage,
+@xref{Configuration Stage},) or they can contain a special procedure called @code{init_targets}, which will be executed
+when entering run stage (after parsing all config files or after @code{init} command, @xref{Entering the Run Stage}.)
+Such procedure can be overriden by ``next level'' script (which sources the original). This concept faciliates code
+reuse when basic target config files provide generic configuration procedures and @code{init_targets} procedure, which
+can then be sourced and enchanced or changed in a ``more specific'' target config file. This is not possible with
+``linear'' config scripts, because sourcing them executes every initialization commands they provide.
+
+@example
+### generic_file.cfg ###
+
+proc setup_my_chip @{chip_name flash_size ram_size@} @{
+ # basic initialization procedure ...
+@}
+
+proc init_targets @{@} @{
+ # initializes generic chip with 4kB of flash and 1kB of RAM
+ setup_my_chip MY_GENERIC_CHIP 4096 1024
+@}
+
+### specific_file.cfg ###
+
+source [find target/generic_file.cfg]
+
+proc init_targets @{@} @{
+ # initializes specific chip with 128kB of flash and 64kB of RAM
+ setup_my_chip MY_CHIP_WITH_128K_FLASH_64KB_RAM 131072 65536
+@}
+@end example
+
+The easiest way to convert ``linear'' config files to @code{init_targets} version is to enclose every line of ``code''
+(i.e. not @code{source} commands, procedures, etc.) in this procedure.
+
+For an example of this scheme see LPC2000 target config files.

+The @code{init_boards} procedure is a similar concept concerning board config files (@xref{The init_board procedure}.)

+@deffn {NAND Driver} mxc
+This driver handles the NAND controller found in Freescale i.MX
+chips. It has support for v1 (i.MX27 and i.MX31) and v2 (i.MX35).
+The driver takes 3 extra arguments, chip (@option{mx27},
+@option{mx31}, @option{mx35}), ecc (@option{noecc}, @option{hwecc})
+and optionally if bad block information should be swapped between
+main area and spare area (@option{biswap}), defaults to off.
+@example

+Load image from file @var{filename} to target memory offset by @var{address} from its load address.
The file format may optionally be specified
(@option{bin}, @option{ihex}, @option{elf}, or @option{s19}).
In addition the following arguments may be specifed:
proc load_image_bin @{fname foffset address length @} @{
# Load data from fname filename at foffset offset to
# target at address. Load at most length bytes.

@cindex SMP
For SMP support following GDB serial protocol packet have been defined :
@itemize @bullet
-@item j - smp status request
+@item j - smp status request
@item J - smp set request
@end itemize
@item @option{jc} packet for reading core id displayed by
GDB connection. Reply is @option{XXXXXXXX} (8 hex digits giving core id) or
@option{E01} for target not smp.
-@item @option{JcXXXXXXXX} (8 hex digits) packet for setting core id displayed at next GDB continue
-(core id -1 is reserved for returning to normal resume mode). Reply @option{E01}
+@item @option{JcXXXXXXXX} (8 hex digits) packet for setting core id displayed at next GDB continue

for target not smp or @option{OK} on success.
@end itemize
Handling of this packet within GDB can be done :
@itemize @bullet
-@item by the creation of an internal variable (i.e @option{_core}) by mean
+@item by the creation of an internal variable (i.e @option{_core}) by mean
of function allocate_computed_value allowing following GDB command.

-print $_core

@example
-# toggle0 : force display of coreid 0
-define toggle0
