7What's this?
8------------
9This file contains status information for the port of U-Boot to the
10Renesas SuperH series of CPUs.
11
12Overview
13--------
14SuperH has an original boot loader. However, source code is dirty, and
15maintenance is not done. To improve sharing and the maintenance of the code,
16Nobuhiro Iwamatsu started the porting to U-Boot in 2007.

18Supported CPUs
19--------------
20
21Renesas SH7750/SH7750R
22^^^^^^^^^^^^^^^^^^^^^^
23This CPU has the SH4 core.
24
25Renesas SH7722
26^^^^^^^^^^^^^^
27This CPU has the SH4AL-DSP core.
28
29Supported Boards
30----------------
31
32Hitachi UL MS7750SE01/MS7750RSE01
33^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
34Board specific code is in board/ms7750se
35To use this board, type "make ms7750se_config".
36Support devices are:
37
38   - SCIF
39   - SDRAM
40   - NOR Flash
41   - Marubun PCMCIA
42
43Hitachi UL MS7722SE01
44^^^^^^^^^^^^^^^^^^^^^
45Board specific code is in board/ms7722se
46To use this board, type "make ms7722se_config".
47Support devices are:
48
49   - SCIF
50   - SDRAM
51   - NOR Flash
52   - Marubun PCMCIA
53   - SMC91x ethernet
54
55Hitachi UL MS7720ERP01
56^^^^^^^^^^^^^^^^^^^^^^
57Board specific code is in board/ms7720se
58To use this board, type "make ms7720se_config".
59Support devices are:
60
61   - SCIF
62   - SDRAM
63   - NOR Flash
64   - Marubun PCMCIA
65
66In SuperH, S-record and binary of made u-boot work on the memory.
67When u-boot is written in the flash, it is necessary to change the
68address by using 'objcopy'::
69
70   ex) shX-linux-objcopy -Ibinary -Osrec u-boot.bin u-boot.flash.srec
71
72Compiler
73--------
74You can use the following of u-boot to compile.
75   - `SuperH Linux Open site <http://www.superh-linux.org/>`_
76   - `KPIT GNU tools <http://www.kpitgnutools.com/>`_
77
78Future
79------
80I plan to support the following CPUs and boards.

84- SH7751R(SH4)
85
86Boards
87^^^^^^
88Many boards ;-)
