| Summary |
| ======= |
| |
| This README is about U-Boot support for SAMSUNG's ARM Cortex-A8 based S5PC1xx |
| family of SoCs (S5PC100 [1] and S5PC110). |
| |
| Currently the following board is supported: |
| |
| * SMDKC100 [2] |
| |
| Toolchain |
| ========= |
| |
| While ARM Cortex-A8 support ARM v7 instruction set (-march=armv7a) we compile |
| with -march=armv5 to allow more compilers to work. For U-Boot code this has |
| no performance impact. |
| |
| Build |
| ===== |
| |
| * SMDKC100 |
| |
| make smdkc100_config |
| make |
| |
| |
| Interfaces |
| ========== |
| |
| cpu |
| |
| To check SoC: |
| |
| if (cpu_is_s5pc100()) |
| printf("cpu is s5pc100\n"); |
| |
| or |
| |
| if (cpu_is_s5pc110()) |
| printf("cpu is s5pc110\n"); |
| |
| gpio |
| not supported yet. |
