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.

42Toolchain
43=========
44
45Either ARMv7 toolchain for 32bit Cortex-A9 systems or ARMv8 (aarch64)
46toolchain for 64bit Cortex-A53/A57 systems. Currently we compile the
4732bit systems with -march=armv5 to allow more compilers to work. (For
48U-Boot code this has no performance impact.)
49
50Currently, ELDK[5], Linaro[6], CodeSourcery[7] and Emdebian[8] supports
51ARMv7. Modern distributions also contain ARMv7 and ARMv8 crosstoolchains
52in their package feeds.
53
54Build
55=====
56
57Locate defconfig in the table above. Then apply standard build procedure:
58
59  make <board>_defconfig
60  make
61
62  Note: Armadillo-800-EVA's U-Boot supports booting from SDcard only.
63        Please see "B.2 Appendix B Boot Specifications" in hardware manual.
