  Summary
  =======
  
  This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1]
  and Cortex-A9/A53/A57 based R-Car[2] family of SoCs. Renesas's RMOBILE/R-Car SoC
  family contains an ARM Cortex-A9/A53/A57.
  
  Currently the following boards are supported:
  
  * KMC KZM-A9-GT [3]
  * Atmark-Techno Armadillo-800-EVA [4]
  * Renesas Electronics Lager
  * Renesas Electronics Koelsch
  * Renesas Electronics Salvator-X  M3
  * Renesas Electronics Salvator-XS H3 ES2.0+
  * Renesas Electronics ULCB M3 / H3 ES2.0+
  
  Toolchain
  =========
  
  Either ARMv7 toolchain for 32bit Cortex-A9 systems or ARMv8 (aarch64)
  toolchain for 64bit Cortex-A53/A57 systems. Currently we compile the
  32bit systems with -march=armv5 to allow more compilers to work. (For
  U-Boot code this has no performance impact.)
  
  Currently, ELDK[5], Linaro[6], CodeSourcery[7] and Emdebian[8] supports
  ARMv7. Modern distributions also contain ARMv7 and ARMv8 crosstoolchains
  in their package feeds.
