- 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:
- | SoC | Board | defconfig

- 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.
- Build
- =====
- Locate defconfig in the table above. Then apply standard build procedure:
- make <board>_defconfig
- make
- Note: Armadillo-800-EVA's U-Boot supports booting from SDcard only.
- Please see "B.2 Appendix B Boot Specifications" in hardware manual.
