1 Summary
2 =======
3
4 This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1]
5 and R-Car[2]family of SoCs. Renesas's RMOBILE/R-Car SoC family contains an ARM
6 Cortex-A9.
7
8 Currently 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

15 Toolchain
16 =========
17
18 ARM Cortex-A9 support ARM v7 instruction set (-march=armv7a).
19 But currently we compile with -march=armv5 to allow more compilers to work.
20 (For U-Boot code this has no performance impact.)
21 Because there was no compiler which is supporting armv7a not much before.
22 Currently, ELDK[5], Linaro[6], CodeSourcey[7] and Emdebian[8] supports -march=armv7a
23 and you can get.
