Summary
=======

This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1]
and Cortex-A9/A53/A57 based R-Car[2] family of SoCs. Renesas's RMOBILE/R-Car SoC
family contains an ARM Cortex-A9/A53/A57.

Currently the following boards are supported:

* KMC KZM-A9-GT [3]
* Atmark-Techno Armadillo-800-EVA [4]
* Renesas Electronics Lager
* Renesas Electronics Koelsch
* Renesas Electronics Salvator-X  M3
* Renesas Electronics Salvator-XS H3 ES2.0+
* Renesas Electronics ULCB M3 / H3 ES2.0+

Toolchain
=========

Either ARMv7 toolchain for 32bit Cortex-A9 systems or ARMv8 (aarch64)
toolchain for 64bit Cortex-A53/A57 systems. Currently we compile the
32bit systems with -march=armv5 to allow more compilers to work. (For
U-Boot code this has no performance impact.)

Currently, ELDK[5], Linaro[6], CodeSourcery[7] and Emdebian[8] supports
ARMv7. Modern distributions also contain ARMv7 and ARMv8 crosstoolchains
in their package feeds.
