4This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1]
Marek Vasutd211d422017-10-01 21:09:53 +02005and Cortex-A9/A53/A57 based R-Car[2] family of SoCs. Renesas's RMOBILE/R-Car SoC
6family contains an ARM Cortex-A9/A53/A57.
Nobuhiro Iwamatsu8c1ccde2012-08-09 17:00:10 +09007
8Currently the following boards are supported:

42Toolchain
43=========
44
Marek Vasutd211d422017-10-01 21:09:53 +020045Either 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.
