1Summary
2=======
3
4This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1]
5and 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.
7
8Currently the following boards are supported:
9
10* KMC KZM-A9-GT [3]
11* Atmark-Techno Armadillo-800-EVA [4]
12* Renesas Electronics Lager
13* Renesas Electronics Koelsch
14* Renesas Electronics Salvator-X  M3
15* Renesas Electronics Salvator-XS H3 ES2.0+
16* Renesas Electronics ULCB M3 / H3 ES2.0+
17
18Toolchain
19=========
20
21Either ARMv7 toolchain for 32bit Cortex-A9 systems or ARMv8 (aarch64)
22toolchain for 64bit Cortex-A53/A57 systems. Currently we compile the
2332bit systems with -march=armv5 to allow more compilers to work. (For
24U-Boot code this has no performance impact.)
25
26Currently, ELDK[5], Linaro[6], CodeSourcery[7] and Emdebian[8] supports
27ARMv7. Modern distributions also contain ARMv7 and ARMv8 crosstoolchains
28in their package feeds.
