+Summary
+=======
+
+This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1]
+and R-Car[2]family of SoCs. Renesas's RMOBILE/R-Car SoC family contains an ARM
+Cortex-A9.
+
+Currently the following boards are supported:
+
+* KMC KZM-A9-GT [3]
+* Atmark-Techno Armadillo-800-EVA [4]
+* Renesas Electronics Lager
+* Renesas Electronics Koelsch
+
+Toolchain
+=========
+
+ARM Cortex-A9 support ARM v7 instruction set (-march=armv7a).
+But currently we compile with -march=armv5 to allow more compilers to work.
+(For U-Boot code this has no performance impact.)
+Because there was no compiler which is supporting armv7a not much before.
+Currently, ELDK[5], Linaro[6], CodeSourcey[7] and Emdebian[8] supports -march=armv7a
+and you can get.
+
+Build
+=====
+
+* KZM-A9-GT
+
+  make kzm9g_config
+  make
+
+* Armadillo-800-EVA
+
+  make armadillo-800eva_config
+  make
+
+  Note: Armadillo-800-EVA's U-Boot supports booting from SDcard only.
+        Please see "B.2 Appendix B Boot Specifications" in hardware manual.
+
+* Lager
+
+  make lager_config
+  make
+
+* Koelsch
+
+  make koelsch_config
+  make
