4This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1]
5and Cortex-A9/A53/A57 based R-Car[2] family of SoCs. Renesas's RMOBILE/R-Car SoC
6family contains an ARM Cortex-A9/A53/A57.

41Toolchain
42=========
43
44Either ARMv7 toolchain for 32bit Cortex-A9 systems or ARMv8 (aarch64)
45toolchain for 64bit Cortex-A53/A57 systems. Currently we compile the
4632bit systems with -march=armv5 to allow more compilers to work. (For
47U-Boot code this has no performance impact.)
48
49Currently, ELDK[5], Linaro[6], CodeSourcery[7] and Emdebian[8] supports
50ARMv7. Modern distributions also contain ARMv7 and ARMv8 crosstoolchains
51in their package feeds.
52
53Build
54=====
55
56Locate defconfig in the table above. Then apply standard build procedure:
57
58  make <board>_defconfig
59  make
60
61  Note: Armadillo-800-EVA's U-Boot supports booting from SDcard only.
62        Please see "B.2 Appendix B Boot Specifications" in hardware manual.
