| 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 | ===== |

| 32 | |
| 33 | To check SoC: |
| 34 | |
| 35 | if (cpu_is_s5pc100()) |
| 36 | printf("cpu is s5pc100\n"); |
| 37 | |
| 38 | or |
| 39 | |
| 40 | if (cpu_is_s5pc110()) |
| 41 | printf("cpu is s5pc110\n"); |
