Summary ======= This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1] family of SoCs. Renesas's RMOBILE SoC family contains an ARM Cortex-A9. Currently the following boards are supported: * KMC KZM-A9-GT [2] * Atmark-Techno Armadillo-800-EVA [3] Toolchain ========= ARM Cortex-A9 support ARM v7 instruction set (-march=armv7a). But currently we compile with -march=armv5 to allow more compilers to work. (For U-Boot code this has no performance impact.) Because there was no compiler which is supporting armv7a not much before. Currently, ELDK[4], Linaro[5], CodeSourcey[6] and Emdebian[7] supports -march=armv7a and you can get.
