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. 17 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 29Renesas SH7780 30^^^^^^^^^^^^^^ 31This CPU has the SH4A core. 32 33Supported Boards 34---------------- 35 36Hitachi UL MS7750SE01/MS7750RSE01 37^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 38Board specific code is in board/ms7750se 39To use this board, type "make ms7750se_config". 40Support devices are: 41 42 - SCIF 43 - SDRAM 44 - NOR Flash 45 - Marubun PCMCIA 46 47Hitachi UL MS7722SE01 48^^^^^^^^^^^^^^^^^^^^^ 49Board specific code is in board/ms7722se 50To use this board, type "make ms7722se_config". 51Support devices are: 52 53 - SCIF 54 - SDRAM 55 - NOR Flash 56 - Marubun PCMCIA 57 - SMC91x ethernet 58 59Hitachi UL MS7720ERP01 60^^^^^^^^^^^^^^^^^^^^^^ 61Board specific code is in board/ms7720se 62To use this board, type "make ms7720se_config". 63Support devices are: 64 65 - SCIF 66 - SDRAM 67 - NOR Flash 68 - Marubun PCMCIA 69 70Renesas R7780MP 71^^^^^^^^^^^^^^^ 72Board specific code is in board/r7780mp 73To use this board, type "make r7780mp_config". 74Support devices are: 75 76 - SCIF 77 - DDR-SDRAM 78 - NOR Flash 79 - Compact Flash 80 - ASIX ethernet 81 - SH7780 PCI bridge 82 - RTL8110 ethernet 83 84In SuperH, S-record and binary of made u-boot work on the memory. 85When u-boot is written in the flash, it is necessary to change the 86address by using 'objcopy':: 87 88 ex) shX-linux-objcopy -Ibinary -Osrec u-boot.bin u-boot.flash.srec 89 90Compiler 91-------- 92You can use the following of u-boot to compile. 93 - `SuperH Linux Open site <http://www.superh-linux.org/>`_ 94 - `KPIT GNU tools <http://www.kpitgnutools.com/>`_ 95 96Future 97------ 98I plan to support the following CPUs and boards. 99 100CPUs 101^^^^ 102- SH7751R(SH4) 103 104Boards 105^^^^^^ 106Many boards ;-) 107
