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.
