  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. Supported Boards
  23. ----------------
  24. Hitachi UL MS7750SE01/MS7750RSE01
  25. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  26. Board specific code is in board/ms7750se
  27. To use this board, type "make ms7750se_config".
  28. Support devices are:
  29. - SCIF
  30. - SDRAM
  31. - NOR Flash
  32. - Marubun PCMCIA
  33. Hitachi UL MS7722SE01
  34. ^^^^^^^^^^^^^^^^^^^^^
  35. Board specific code is in board/ms7722se
  36. To use this board, type "make ms7722se_config".
  37. Support devices are:
  38. - SCIF
  39. - SDRAM
  40. - NOR Flash
  41. - Marubun PCMCIA
  42. - SMC91x ethernet
  43. Hitachi UL MS7720ERP01
  44. ^^^^^^^^^^^^^^^^^^^^^^
  45. Board specific code is in board/ms7720se
  46. To use this board, type "make ms7720se_config".
  47. Support devices are:
  48. - SCIF
  49. - SDRAM
  50. - NOR Flash
  51. - Marubun PCMCIA
  52. In SuperH, S-record and binary of made u-boot work on the memory.
  53. When u-boot is written in the flash, it is necessary to change the
  54. address by using 'objcopy'::
  55. ex) shX-linux-objcopy -Ibinary -Osrec u-boot.bin u-boot.flash.srec
  56. Compiler
  57. --------
  58. You can use the following of u-boot to compile.
  59. - `SuperH Linux Open site <http://www.superh-linux.org/>`_
  60. - `KPIT GNU tools <http://www.kpitgnutools.com/>`_
  61. Future
  62. ------
  63. I plan to support the following CPUs and boards.
  64. CPUs
  65. ^^^^
  66. - SH7751R(SH4)
  67. Boards
  68. ^^^^^^
  69. Many boards ;-)
