41Toolchain
42=========
43
Marek Vasutfd107e32017-10-01 21:09:53 +0200[diff] [blame]44Either ARMv7 toolchain for 32bit Cortex-A9 systems or ARMv8 (aarch64)
45toolchain for 64bit Cortex-A53/A57 systems. Currently we compile the
4632bit systems with -march=armv5 to allow more compilers to work. (For
47U-Boot code this has no performance impact.)
48
49Currently, ELDK[5], Linaro[6], CodeSourcery[7] and Emdebian[8] supports
50ARMv7. Modern distributions also contain ARMv7 and ARMv8 crosstoolchains
51in their package feeds.
