@node REGION_ALIAS
@subsection Assign alias names to memory regions
@kindex REGION_ALIAS(@var{alias}, @var{region})
@cindex region alias
@cindex region names
Alias names can be added to existing memory regions created with the
@ref{MEMORY} command. Each name corresponds to at most one memory region.
@smallexample
REGION_ALIAS(@var{alias}, @var{region})
@end smallexample
The @code{REGION_ALIAS} function creates an alias name @var{alias} for the
memory region @var{region}. This allows a flexible mapping of output sections
to memory regions. An example follows.
Suppose we have an application for embedded systems which come with various
memory storage devices. All have a general purpose, volatile memory @code{RAM}
that allows code execution or data storage. Some may have a read-only,
non-volatile memory @code{ROM} that allows code execution and read-only data
access. The last variant is a read-only, non-volatile memory @code{ROM2} with
read-only data access and no code execution capability. We have four output
sections:
@itemize @bullet
@item
@code{.text} program code;
@item
@code{.rodata} read-only data;
@item
@code{.data} read-write initialized data;
@item
@code{.bss} read-write zero initialized data.
@end itemize
The goal is to provide a linker command file that contains a system independent
part defining the output sections and a system dependent part mapping the
output sections to the memory regions available on the system. Our embedded
systems come with three different memory setups @code{A}, @code{B} and
@code{C}:
@multitable @columnfractions .25 .25 .25 .25
@item Section @tab Variant A @tab Variant B @tab Variant C
@item .text @tab RAM @tab ROM @tab ROM
@item .rodata @tab RAM @tab ROM @tab ROM2
@item .data @tab RAM @tab RAM/ROM @tab RAM/ROM2
@item .bss @tab RAM @tab RAM @tab RAM
@end multitable
The notation @code{RAM/ROM} or @code{RAM/ROM2} means that this section is
loaded into region @code{ROM} or @code{ROM2} respectively. Please note that
the load address of the @code{.data} section starts in all three variants at
the end of the @code{.rodata} section.
The base linker script that deals with the output sections follows. It
includes the system dependent @code{linkcmds.memory} file that describes the
memory layout:
@smallexample
INCLUDE linkcmds.memory
SECTIONS
@{
.text :
@{
*(.text)
@} > REGION_TEXT
.rodata :
@{
*(.rodata)
rodata_end = .;
@} > REGION_RODATA
.data : AT (rodata_end)
@{
data_start = .;
*(.data)
@} > REGION_DATA
data_size = SIZEOF(.data);
data_load_start = LOADADDR(.data);
.bss :
@{
*(.bss)
@} > REGION_BSS
@}
@end smallexample
Now we need three different @code{linkcmds.memory} files to define memory
regions and alias names. The content of @code{linkcmds.memory} for the three
variants @code{A}, @code{B} and @code{C}:
@table @code
@item A
Here everything goes into the @code{RAM}.
@smallexample
MEMORY
@{
RAM : ORIGIN = 0, LENGTH = 4M
@}
REGION_ALIAS("REGION_TEXT", RAM);
REGION_ALIAS("REGION_RODATA", RAM);
REGION_ALIAS("REGION_DATA", RAM);
REGION_ALIAS("REGION_BSS", RAM);
@end smallexample
@item B
Program code and read-only data go into the @code{ROM}. Read-write data goes
into the @code{RAM}. An image of the initialized data is loaded into the
@code{ROM} and will be copied during system start into the @code{RAM}.
@smallexample
MEMORY
@{
ROM : ORIGIN = 0, LENGTH = 3M
RAM : ORIGIN = 0x10000000, LENGTH = 1M
@}
REGION_ALIAS("REGION_TEXT", ROM);
REGION_ALIAS("REGION_RODATA", ROM);
REGION_ALIAS("REGION_DATA", RAM);
REGION_ALIAS("REGION_BSS", RAM);
@end smallexample
@item C
Program code goes into the @code{ROM}. Read-only data goes into the
@code{ROM2}. Read-write data goes into the @code{RAM}. An image of the
initialized data is loaded into the @code{ROM2} and will be copied during
system start into the @code{RAM}.
@smallexample
MEMORY
@{
ROM : ORIGIN = 0, LENGTH = 2M
ROM2 : ORIGIN = 0x10000000, LENGTH = 1M
RAM : ORIGIN = 0x20000000, LENGTH = 1M
@}
REGION_ALIAS("REGION_TEXT", ROM);
REGION_ALIAS("REGION_RODATA", ROM2);
REGION_ALIAS("REGION_DATA", RAM);
REGION_ALIAS("REGION_BSS", RAM);
@end smallexample
@end table
It is possible to write a common system initialization routine to copy the
@code{.data} section from @code{ROM} or @code{ROM2} into the @code{RAM} if
necessary:
@smallexample
#include <string.h>
extern char data_start [];
extern char data_size [];
extern char data_load_start [];
void copy_data(void)
@{
if (data_start != data_load_start)
@{
memcpy(data_start, data_load_start, (size_t) data_size);
@}
