  1. U-Boot for Renesas SuperH
  2. Last update 01/18/2008 by Nobuhiro Iwamatsu
  3. ================================================================================
  4. 0. What's this?
  5. This file contains status information for the port of U-Boot to the
  6. Renesas SuperH series of CPUs.
  7. ================================================================================
  8. 1. Overview
  9. SuperH has an original boot loader. However, source code is dirty, and
  10. maintenance is not done.
  11. To improve sharing and the maintenance of the code, Nobuhiro Iwamatsu
  12. started the porting to u-boot in 2007.
  13. ================================================================================
  14. 2. Supported CPUs
  15. 2.1. Renesas SH7750/SH7750R
  16. This CPU has the SH4 core.
  17. 2.2. Renesas SH7722
  18. This CPU has the SH4AL-DSP core.
  19. 2.3. Renesas SH7720
  20. This CPU has the SH3 core.
  21. 2.4. Renesas SH7710/SH7712
  22. This CPU has the SH3-DSP core and Ethernet controller.
  23. 2.5. Renesas SH7780
  24. This CPU has the SH4A core.
  25. ================================================================================
  26. 3. Supported Boards
  27. 3.1. Hitachi UL MS7750SE01/MS7750RSE01
  28. Board specific code is in board/ms7750se
  29. To use this board, type "make ms7750se_config".
  30. Support devices are :
  31. - SCIF
  32. - SDRAM
  33. - NOR Flash
  34. - Marubun PCMCIA
  35. 3.2. Hitachi UL MS7722SE01
  36. Board specific code is in board/ms7722se
  37. To use this board, type "make ms7722se_config".
  38. Support devices are :
  39. - SCIF
  40. - SDRAM
  41. - NOR Flash
  42. - Marubun PCMCIA
  43. - SMC91x ethernet
  44. 3.2. Hitachi UL MS7720ERP01
  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. 3.3. Renesas R7780MP
  53. Board specific code is in board/r7780mp
  54. To use this board, type "make r7780mp_config".
  55. Support devices are :
  56. - SCIF
  57. - DDR-SDRAM
  58. - NOR Flash
  59. - Compact Flash
  60. - ASIX ethernet
  61. - SH7780 PCI bridge
  62. - RTL8110 ethernet
  63. ** README **
  64. In SuperH, S-record and binary of made u-boot work on the memory.
  65. When u-boot is written in the flash, it is necessary to change the
  66. address by using 'objcopy'.
  67. ex) shX-linux-objcopy -Ibinary -Osrec u-boot.bin u-boot.flash.srec
  68. ================================================================================
  69. 4. Compiler
  70. You can use the following of u-boot to compile.
  71. - SuperH Linux Open site
  72. http://www.superh-linux.org/
  73. - KPIT GNU tools
  74. http://www.kpitgnutools.com/
  75. ================================================================================
  76. 5. Future
  77. I plan to support the following CPUs and boards.
  78. 5.1. CPUs
  79. - SH7751R(SH4)
  80. - SH7785(SH4)
  81. 5.2. Boards
  82. - Many boards ;-)
