| 2 | Summary | |
| 3 | ======= | |
| 4 | ||
| 5 | This README is about U-Boot support for SAMSUNG's ARM Cortex-A8 based S5PC1xx | |
| 6 | family of SoCs (S5PC100 [1] and S5PC110). | |
| 7 | ||
| 8 | Currently the following board is supported: | |
| 9 | ||
| 10 | * SMDKC100 [2] | |
| 11 | ||
| 12 | Toolchain | |
| 13 | ========= | |
| 14 | ||
| 15 | While ARM Cortex-A8 support ARM v7 instruction set (-march=armv7a) we compile | |
| 16 | with -march=armv5 to allow more compilers to work. For U-Boot code this has | |
| 17 | no performance impact. | |
| 18 | ||
| 19 | Build | |
| 20 | ===== | |
| 21 | ||
| 22 | * SMDKC100 | |

| 33 | To check SoC: | |
| 34 | ||
| 35 | if (cpu_is_s5pc100()) | |
| 36 | printf("cpu is s5pc100\n"); | |
| 37 | ||
| 38 | or | |

| 40 | if (cpu_is_s5pc110()) | |
| 41 | printf("cpu is s5pc110\n"); | |
