   1Summary
   2=======
   3
   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.

   8Currently the following boards are supported:

  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.
