+@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);
+ @}
+@}
+@end smallexample
+
@node Miscellaneous Commands
@subsection Other Linker Script Commands
There are a few other linker scripts commands.
region. The region name has no meaning outside of the linker script.
Region names are stored in a separate name space, and will not conflict
with symbol names, file names, or section names. Each memory region
-must have a distinct name.
+must have a distinct name within the @code{MEMORY} command. However you can
+add later alias names to existing memory regions with the @ref{REGION_ALIAS}
+command.
@cindex memory region attributes
The @var{attr} string is an optional list of attributes that specify
