   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.
