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

41 Toolchain
42 =========
43
44 Either ARMv7 toolchain for 32bit Cortex-A9 systems or ARMv8 (aarch64)
45 toolchain for 64bit Cortex-A53/A57 systems. Currently we compile the
46 32bit systems with -march=armv5 to allow more compilers to work. (For
47 U-Boot code this has no performance impact.)
48
49 Currently, ELDK[5], Linaro[6], CodeSourcery[7] and Emdebian[8] supports
50 ARMv7. Modern distributions also contain ARMv7 and ARMv8 crosstoolchains
51 in their package feeds.
52
53 Build
54 =====
55
56 Locate 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.
