1 | Summary |
| 2 | ======= | |
| 3 | ||
| 4 | This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1] | |
| 5 | family of SoCs. Renesas's RMOBILE SoC family contains an ARM Cortex-A9. | |
| 6 | ||
| 7 | Currently the following boards are supported: | |
| 8 | ||
| 9 | * KMC KZM-A9-GT [2] | |
| 10 | ||
| 11 | * Atmark-Techno Armadillo-800-EVA [3] | |
| 12 | ||
| 13 | Toolchain | |
| 14 | ========= | |
| 15 | ||
| 16 | ARM Cortex-A9 support ARM v7 instruction set (-march=armv7a). | |
| 17 | But currently we compile with -march=armv5 to allow more compilers to work. | |
| 18 | (For U-Boot code this has no performance impact.) | |
| 19 | Because there was no compiler which is supporting armv7a not much before. | |
| 20 | Currently, ELDK[4], Linaro[5], CodeSourcey[6] and Emdebian[7] supports -march=armv7a | |
| 21 | and you can get. | |
