| ====== |
| |
| 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. |
| |
| Renesas SH7780 |
| ^^^^^^^^^^^^^^ |
| This CPU has the SH4A 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 |
| |
| Renesas R7780MP |
| ^^^^^^^^^^^^^^^ |
| Board specific code is in board/r7780mp |
| To use this board, type "make r7780mp_config". |
| Support devices are: |
| |
| - SCIF |
| - DDR-SDRAM |
| - NOR Flash |
| - Compact Flash |
| - ASIX ethernet |
| - SH7780 PCI bridge |
| - RTL8110 ethernet |
| |
| 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 ;-) |
