-Loading Data into Memory Values
--------------------------------
-The loader device allows memory values to be set from the command line. This
-can be done by following the syntax below:
-
- -device loader,addr=<addr>,data=<data>,data-len=<data-len>
- [,data-be=<data-be>][,cpu-num=<cpu-num>]
-
- <addr> - The address to store the data in.
- <data> - The value to be written to the address. The maximum size of
- the data is 8 bytes.
- <data-len> - The length of the data in bytes. This argument must be
- included if the data argument is.
- <data-be> - Set to true if the data to be stored on the guest should be
- written as big endian data. The default is to write little
- endian data.
- <cpu-num> - The number of the CPU's address space where the data should
- be loaded. If not specified the address space of the first
- CPU is used.
-
-All values are parsed using the standard QemuOps parsing. This allows the user
-to specify any values in any format supported. By default the values
-will be parsed as decimal. To use hex values the user should prefix the number
-with a '0x'.
-
-An example of loading value 0x8000000e to address 0xfd1a0104 is:
- -device loader,addr=0xfd1a0104,data=0x8000000e,data-len=4
-
-Setting a CPU's Program Counter
--------------------------------
-The loader device allows the CPU's PC to be set from the command line. This
-can be done by following the syntax below:
-
- -device loader,addr=<addr>,cpu-num=<cpu-num>
-
- <addr> - The value to use as the CPU's PC.
- <cpu-num> - The number of the CPU whose PC should be set to the
- specified value.
-
-All values are parsed using the standard QemuOps parsing. This allows the user
-to specify any values in any format supported. By default the values
-will be parsed as decimal. To use hex values the user should prefix the number
-with a '0x'.
-
-An example of setting CPU 0's PC to 0x8000 is:
- -device loader,addr=0x8000,cpu-num=0
-
-Loading Files
--------------
-The loader device also allows files to be loaded into memory. It can load ELF,
-U-Boot, and Intel HEX executable formats as well as raw images. The syntax is
-shown below:
-
- -device loader,file=<file>[,addr=<addr>][,cpu-num=<cpu-num>][,force-raw=<raw>]
-
- <file> - A file to be loaded into memory
- <addr> - The memory address where the file should be loaded. This is
- required for raw images and ignored for non-raw files.
- <cpu-num> - This specifies the CPU that should be used. This is an
- optional argument and will cause the CPU's PC to be set to
- the memory address where the raw file is loaded or the entry
- point specified in the executable format header. This option
- should only be used for the boot image.
- This will also cause the image to be written to the specified
- CPU's address space. If not specified, the default is CPU 0.
- <force-raw> - Setting force-raw=on forces the file to be treated as a raw
- image. This can be used to load supported executable formats
- as if they were raw.
-
-All values are parsed using the standard QemuOps parsing. This allows the user
-to specify any values in any format supported. By default the values
-will be parsed as decimal. To use hex values the user should prefix the number
-with a '0x'.
-
-An example of loading an ELF file which CPU0 will boot is shown below:
- -device loader,file=./images/boot.elf,cpu-num=0
-
-Restrictions and ToDos
-----------------------
- - At the moment it is just assumed that if you specify a cpu-num then you
- want to set the PC as well. This might not always be the case. In future
- the internal state 'set_pc' (which exists in the generic loader now) should
- be exposed to the user so that they can choose if the PC is set or not.

+
+Loading Data into Memory Values
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+The loader device allows memory values to be set from the command line. This
+can be done by following the syntax below::
+
+ -device loader,addr=<addr>,data=<data>,data-len=<data-len> \
+ [,data-be=<data-be>][,cpu-num=<cpu-num>]
+
+``<addr>``
+ The address to store the data in.
+
+``<data>``
+ The value to be written to the address. The maximum size of the data
+ is 8 bytes.
+
+``<data-len>``
+ The length of the data in bytes. This argument must be included if
+ the data argument is.
+
+``<data-be>``
+ Set to true if the data to be stored on the guest should be written
+ as big endian data. The default is to write little endian data.
