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