   1 Summary
   2 =======
   3
   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.
   7
   8 Currently the following boards are supported:
   9
  10 * KMC KZM-A9-GT [3]
  11 * Atmark-Techno Armadillo-800-EVA [4]
  12 * Renesas Electronics Lager
  13 * Renesas Electronics Koelsch
  14 * Renesas Electronics Salvator-X  M3
  15 * Renesas Electronics Salvator-XS H3 ES2.0+
  16 * Renesas Electronics ULCB M3 / H3 ES2.0+
  17
  18 Toolchain
  19 =========
  20
  21 Either ARMv7 toolchain for 32bit Cortex-A9 systems or ARMv8 (aarch64)
  22 toolchain for 64bit Cortex-A53/A57 systems. Currently we compile the
  23 32bit systems with -march=armv5 to allow more compilers to work. (For
  24 U-Boot code this has no performance impact.)
  25
  26 Currently, ELDK[5], Linaro[6], CodeSourcery[7] and Emdebian[8] supports
  27 ARMv7. Modern distributions also contain ARMv7 and ARMv8 crosstoolchains
  28 in their package feeds.
