4This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1]
5and R-Car[2]family of SoCs. Renesas's RMOBILE/R-Car SoC family contains an ARM
6Cortex-A9.

8Currently 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

15Toolchain
16=========
17
18ARM Cortex-A9 support ARM v7 instruction set (-march=armv7a).
19But currently we compile with -march=armv5 to allow more compilers to work.
20(For U-Boot code this has no performance impact.)
21Because there was no compiler which is supporting armv7a not much before.
22Currently, ELDK[5], Linaro[6], CodeSourcey[7] and Emdebian[8] supports -march=armv7a
23and you can get.
