  3. SuperH
  4. ======
  5. What's this?
  6. ------------
  7. This file contains status information for the port of U-Boot to the
  8. Renesas SuperH series of CPUs.
  9. Overview
  10. --------
  11. SuperH has an original boot loader. However, source code is dirty, and
  12. maintenance is not done. To improve sharing and the maintenance of the code,
  13. Nobuhiro Iwamatsu started the porting to U-Boot in 2007.
  14. Supported CPUs
  15. --------------
  16. Renesas SH7750/SH7750R
  17. ^^^^^^^^^^^^^^^^^^^^^^
  18. This CPU has the SH4 core.
  19. Renesas SH7722
  20. ^^^^^^^^^^^^^^
  21. This CPU has the SH4AL-DSP core.
  22. Renesas SH7780
  23. ^^^^^^^^^^^^^^
  24. This CPU has the SH4A core.
  25. Supported Boards
  26. ----------------
  27. Hitachi UL MS7750SE01/MS7750RSE01
  28. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  29. Board specific code is in board/ms7750se
  30. To use this board, type "make ms7750se_config".
  31. Support devices are:
  32. - SCIF
  33. - SDRAM
  34. - NOR Flash
  35. - Marubun PCMCIA
  36. Hitachi UL MS7722SE01
  37. ^^^^^^^^^^^^^^^^^^^^^
  38. Board specific code is in board/ms7722se
  39. To use this board, type "make ms7722se_config".
  40. Support devices are:
  41. - SCIF
  42. - SDRAM
  43. - NOR Flash
  44. - Marubun PCMCIA
  45. - SMC91x ethernet
  46. Hitachi UL MS7720ERP01
  47. ^^^^^^^^^^^^^^^^^^^^^^
  48. Board specific code is in board/ms7720se
  49. To use this board, type "make ms7720se_config".
  50. Support devices are:
  51. - SCIF
  52. - SDRAM
  53. - NOR Flash
  54. - Marubun PCMCIA
  55. Renesas R7780MP
  56. ^^^^^^^^^^^^^^^
  57. Board specific code is in board/r7780mp
  58. To use this board, type "make r7780mp_config".
  59. Support devices are:
  60. - SCIF
  61. - DDR-SDRAM
  62. - NOR Flash
  63. - Compact Flash
  64. - ASIX ethernet
  65. - SH7780 PCI bridge
  66. - RTL8110 ethernet
  67. In SuperH, S-record and binary of made u-boot work on the memory.
  68. When u-boot is written in the flash, it is necessary to change the
  69. address by using 'objcopy'::
  70. ex) shX-linux-objcopy -Ibinary -Osrec u-boot.bin u-boot.flash.srec
  71. Compiler
  72. --------
  73. You can use the following of u-boot to compile.
  74. - `SuperH Linux Open site <http://www.superh-linux.org/>`_
  75. - `KPIT GNU tools <http://www.kpitgnutools.com/>`_
  76. Future
  77. ------
  78. I plan to support the following CPUs and boards.
  79. CPUs
  80. ^^^^
  81. - SH7751R(SH4)
  82. Boards
  83. ^^^^^^
  84. Many boards ;-)
