5 | ================================================================================ | |
6 | 0. What's this? | |
7 | This file contains status information for the port of U-Boot to the | |
8 | Renesas SuperH series of CPUs. | |
9 | ||
10 | ================================================================================ | |
11 | 1. Overview | |
12 | SuperH has an original boot loader. However, source code is dirty, and | |
13 | maintenance is not done. | |
14 | To improve sharing and the maintenance of the code, Nobuhiro Iwamatsu | |
15 | started the porting to u-boot in 2007. | |
16 | ||
17 | ================================================================================ | |
18 | 2. Supported CPUs | |
19 | ||
20 | 2.1. Renesas SH7750/SH7750R | |
21 | This CPU has the SH4 core. | |
22 | ||
23 | 2.2. Renesas SH7722 | |
24 | This CPU has the SH4AL-DSP core. | |
25 | ||
26 | 2.3. Renesas SH7720 | |
27 | This CPU has the SH3 core. | |
28 | ||
29 | 2.4. Renesas SH7710/SH7712 | |
30 | This CPU has the SH3-DSP core and Ethernet controller. | |
31 | ||
32 | 2.5. Renesas SH7780 | |
33 | This CPU has the SH4A core. | |
34 | ||
35 | ================================================================================ | |
36 | 3. Supported Boards | |

76 | - RTL8110 ethernet | |
77 | ||
78 | ** README ** | |
79 | In SuperH, S-record and binary of made u-boot work on the memory. | |
80 | When u-boot is written in the flash, it is necessary to change the | |
81 | address by using 'objcopy'. | |
82 | ex) shX-linux-objcopy -Ibinary -Osrec u-boot.bin u-boot.flash.srec | |
83 | ||
84 | ================================================================================ | |
85 | 4. Compiler | |
86 | You can use the following of u-boot to compile. | |
87 | - SuperH Linux Open site | |
88 | http://www.superh-linux.org/ | |
89 | - KPIT GNU tools | |
90 | http://www.kpitgnutools.com/ | |
91 | ||
92 | ================================================================================ | |
93 | 5. Future | |
94 | I plan to support the following CPUs and boards. | |
95 | 5.1. CPUs | |
96 | - SH7751R(SH4) | |
97 | - SH7785(SH4) | |
98 | ||
99 | 5.2. Boards | |
100 | - Many boards ;-) | |
