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.
