 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)
