This board has not been converted to CONFIG_DM by the deadline of v2020.01 and is missing other conversions which depend on this as well. Remove it.

What's this?
|
|
------------
|
|
This file contains status information for the port of U-Boot to the
|
|
Renesas SuperH series of CPUs.
|
|
|
|
Overview
|
|
--------
|
|
SuperH has an original boot loader. However, source code is dirty, and
|
|
maintenance is not done. To improve sharing and the maintenance of the code,
|
|
Nobuhiro Iwamatsu started the porting to U-Boot in 2007.
|
|
|
|
Supported CPUs
|
|
--------------
|
|
|
|
Renesas SH7750/SH7750R
|
|
^^^^^^^^^^^^^^^^^^^^^^
|
|
This CPU has the SH4 core.
|
|
|
|
Renesas SH7722
|
|
^^^^^^^^^^^^^^

|
|
Supported Boards
|
|
----------------
|
|
|
|
Hitachi UL MS7750SE01/MS7750RSE01
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
Board specific code is in board/ms7750se
|
|
To use this board, type "make ms7750se_config".
|
|
Support devices are:
|
|
|
|
- SCIF
|
|
- SDRAM
|
|
- NOR Flash
|
|
- Marubun PCMCIA
|
|
|
|

|
|
^^^^^^^^^^^^^^^^^^^^^
|
|
Board specific code is in board/ms7722se
|
|
To use this board, type "make ms7722se_config".
|
|
Support devices are:
|
|
|
|
- SCIF
|
|

Hitachi UL MS7720ERP01
|
|
^^^^^^^^^^^^^^^^^^^^^^
|
|
Board specific code is in board/ms7720se
|
|
To use this board, type "make ms7720se_config".
|
|
Support devices are:

|
|
|
|
In SuperH, S-record and binary of made u-boot work on the memory.
|
|
When u-boot is written in the flash, it is necessary to change the
|
|
address by using 'objcopy'::
|
|
|
|
ex) shX-linux-objcopy -Ibinary -Osrec u-boot.bin u-boot.flash.srec
|
|
|
|
Compiler
|
|
--------
|
|
You can use the following of u-boot to compile.
|
|
- `SuperH Linux Open site <http://www.superh-linux.org/>`_
|
|
- `KPIT GNU tools <http://www.kpitgnutools.com/>`_
|
|
|
|
Future
|
|
------
|
|
I plan to support the following CPUs and boards.
