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