- 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

- 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
