Summary
=======

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

Currently the following boards are supported:

* KMC KZM-A9-GT [3]
* Atmark-Techno Armadillo-800-EVA [4]
* Renesas Electronics Lager
* Renesas Electronics Koelsch

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[5], Linaro[6], CodeSourcey[7] and Emdebian[8] supports -march=armv7a
and you can get.

Build
=====

* KZM-A9-GT

  make kzm9g_config
  make

* Armadillo-800-EVA

  make armadillo-800eva_config
  make

  Note: Armadillo-800-EVA's U-Boot supports booting from SDcard only.
        Please see "B.2 Appendix B Boot Specifications" in hardware manual.

* Lager

  make lager_config
  make

* Koelsch

  make koelsch_config
  make
