   1 Summary
   2 =======

   4 This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1]
   5 family of SoCs. Renesas's RMOBILE SoC family contains an ARM Cortex-A9.
   6
   7 Currently the following boards are supported:
   8
   9 * KMC KZM-A9-GT [2]
  10
  11 * Atmark-Techno Armadillo-800-EVA [3]
  12
  13 Toolchain
  14 =========
  15
  16 ARM Cortex-A9 support ARM v7 instruction set (-march=armv7a).
  17 But currently we compile with -march=armv5 to allow more compilers to work.
  18 (For U-Boot code this has no performance impact.)
  19 Because there was no compiler which is supporting armv7a not much before.
  20 Currently, ELDK[4], Linaro[5], CodeSourcey[6] and Emdebian[7] supports -march=armv7a
  21 and you can get.
