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