 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.
+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

 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.
+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.
 
 Build
 =====
 
-* KZM-A9-GT
+Locate defconfig in the table above. Then apply standard build procedure:
 
-  make kzm9g_config
-  make
-
-* Armadillo-800-EVA
-
-  make armadillo-800eva_config
+  make <board>_defconfig
   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
