| What's this? | |
| ------------ | |
| This file contains status information for the port of U-Boot to the | |
| Renesas SuperH series of CPUs. | |
| Overview | |
| -------- | |
| SuperH has an original boot loader. However, source code is dirty, and | |
| maintenance is not done. To improve sharing and the maintenance of the code, | |
| Nobuhiro Iwamatsu started the porting to U-Boot in 2007. | |
| Supported CPUs | |
| -------------- | |
| Renesas SH7750/SH7750R | |
| ^^^^^^^^^^^^^^^^^^^^^^ | |
| This CPU has the SH4 core. | |
| Renesas SH7722 | |
| ^^^^^^^^^^^^^^ | |
| This CPU has the SH4AL-DSP core. | |
| Supported Boards | |
| ---------------- | |
| Hitachi UL MS7750SE01/MS7750RSE01 | |
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ | |
| Board specific code is in board/ms7750se | |
| To use this board, type "make ms7750se_config". | |
| Support devices are: | |
| - SCIF | |
| - SDRAM | |
| - NOR Flash | |
| - Marubun PCMCIA | |
| Hitachi UL MS7722SE01 | |
| ^^^^^^^^^^^^^^^^^^^^^ | |
| Board specific code is in board/ms7722se | |
| To use this board, type "make ms7722se_config". | |
| Support devices are: | |
| - SCIF | |
| - SDRAM | |
| - NOR Flash | |
| - Marubun PCMCIA | |
| - SMC91x ethernet | |
| Hitachi UL MS7720ERP01 | |
| ^^^^^^^^^^^^^^^^^^^^^^ | |
| Board specific code is in board/ms7720se | |
| To use this board, type "make ms7720se_config". | |
| Support devices are: | |
| - SCIF | |
| - SDRAM | |
| - NOR Flash | |
| - Marubun PCMCIA | |
| In SuperH, S-record and binary of made u-boot work on the memory. | |
| When u-boot is written in the flash, it is necessary to change the | |
| address by using 'objcopy':: | |
| ex) shX-linux-objcopy -Ibinary -Osrec u-boot.bin u-boot.flash.srec | |
| Compiler | |
| -------- | |
| You can use the following of u-boot to compile. | |
| - `SuperH Linux Open site <http://www.superh-linux.org/>`_ | |
| - `KPIT GNU tools <http://www.kpitgnutools.com/>`_ | |
| Future | |
| ------ | |
| I plan to support the following CPUs and boards. | |
| CPUs | |
| ^^^^ | |
| - SH7751R(SH4) | |
| Boards | |
| ^^^^^^ | |
| Many boards ;-) |
