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:
|

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.
