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.

7 Currently the following boards are supported:

9 * KMC KZM-A9-GT [2]
10
11 * Atmark-Techno Armadillo-800-EVA [3]

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.
