Summary ======= This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1] and R-Car[2]family of SoCs. Renesas's RMOBILE/R-Car SoC family contains an ARM Cortex-A9. Currently the following boards are supported: * KMC KZM-A9-GT [3] * Atmark-Techno Armadillo-800-EVA [4] * Renesas Electronics Lager * Renesas Electronics Koelsch 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[5], Linaro[6], CodeSourcey[7] and Emdebian[8] supports -march=armv7a and you can get. Build ===== * KZM-A9-GT make kzm9g_config make * Armadillo-800-EVA make armadillo-800eva_config make Note: Armadillo-800-EVA's U-Boot supports booting from SDcard only. Please see "B.2 Appendix B Boot Specifications" in hardware manual. * Lager make lager_config make * Koelsch make koelsch_config make Links ===== [1] Renesas RMOBILE: http://am.renesas.com/products/soc/assp/mobile/r_mobile/index.jsp [2] Renesas R-Car: http://am.renesas.com/products/soc/assp/automotive/index.jsp [3] KZM-A9-GT http://www.kmckk.co.jp/kzma9-gt/index.html [4] Armadillo-800-EVA http://armadillo.atmark-techno.com/armadillo-800-EVA [5] ELDK http://www.denx.de/wiki/view/ELDK-5/WebHome#Section_1.6.
