| 3 | |
| 4 | This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1] |
Nobuhiro Iwamatsu | 991008e | 2013-12-10 14:52:20 +0900 | [diff] [blame] | 5 | and R-Car[2]family of SoCs. Renesas's RMOBILE/R-Car SoC family contains an ARM |
| 6 | Cortex-A9. |
Nobuhiro Iwamatsu | 8c1ccde | 2012-08-09 17:00:10 +0900 | [diff] [blame] | 7 | |
| 8 | Currently the following boards are supported: |

| 15 | Toolchain |
| 16 | ========= |
| 17 | |
| 18 | ARM Cortex-A9 support ARM v7 instruction set (-march=armv7a). |
| 19 | But currently we compile with -march=armv5 to allow more compilers to work. |
| 20 | (For U-Boot code this has no performance impact.) |
| 21 | Because there was no compiler which is supporting armv7a not much before. |
Nobuhiro Iwamatsu | 991008e | 2013-12-10 14:52:20 +0900 | [diff] [blame] | 22 | Currently, ELDK[5], Linaro[6], CodeSourcey[7] and Emdebian[8] supports -march=armv7a |
Nobuhiro Iwamatsu | 8c1ccde | 2012-08-09 17:00:10 +0900 | [diff] [blame] | 23 | and you can get. |
