42Toolchain
43=========
44
Marek Vasutfd107e32017-10-01 21:09:53 +0200[diff] [blame]45Either ARMv7 toolchain for 32bit Cortex-A9 systems or ARMv8 (aarch64)
46toolchain for 64bit Cortex-A53/A57 systems. Currently we compile the
4732bit systems with -march=armv5 to allow more compilers to work. (For
48U-Boot code this has no performance impact.)
49
50Currently, ELDK[5], Linaro[6], CodeSourcery[7] and Emdebian[8] supports
51ARMv7. Modern distributions also contain ARMv7 and ARMv8 crosstoolchains
52in their package feeds.
