1 | Summary | |
2 | ======= | |
3 | ||
4 | This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1] | |
5 | and R-Car[2]family of SoCs. Renesas's RMOBILE/R-Car SoC family contains an ARM | |
6 | Cortex-A9. | |
7 | ||
8 | Currently the following boards are supported: | |
9 | ||
10 | * KMC KZM-A9-GT [3] | |
11 | * Atmark-Techno Armadillo-800-EVA [4] | |
12 | * Renesas Electronics Lager | |
13 | * Renesas Electronics Koelsch | |
14 | ||
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. | |
22 | Currently, ELDK[5], Linaro[6], CodeSourcey[7] and Emdebian[8] supports -march=armv7a | |
23 | and you can get. | |
