1Summary 2======= 3 4This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1] 5family of SoCs. Renesas's RMOBILE SoC family contains an ARM Cortex-A9. 6 7Currently the following boards are supported: 8 9* KMC KZM-A9-GT [2] 10 11* Atmark-Techno Armadillo-800-EVA [3] 12 13Toolchain 14========= 15 16ARM Cortex-A9 support ARM v7 instruction set (-march=armv7a). 17But currently we compile with -march=armv5 to allow more compilers to work. 18(For U-Boot code this has no performance impact.) 19Because there was no compiler which is supporting armv7a not much before. 20Currently, ELDK[4], Linaro[5], CodeSourcey[6] and Emdebian[7] supports -march=armv7a 21and you can get. 22 23Build 24===== 25 26* KZM-A9-GT 27 28make kzm9g_config 29make 30 31* Armadillo-800-EVA 32 33make armadillo-800eva_config 34make 35 36Links 37===== 38 39[1] Renesas RMOBILE: 40 41http://am.renesas.com/products/soc/assp/mobile/r_mobile/index.jsp 42 43[2] KZM-A9-GT 44 45http://www.kmckk.co.jp/kzma9-gt/index.html 46 47[3] Armadillo-800-EVA 48 49http://armadillo.atmark-techno.com/armadillo-800-EVA 50 51[4] ELDK 52 53http://www.denx.de/wiki/view/ELDK-5/WebHome#Section_1.6. 54 55[5] Linaro 56 57http://www.linaro.org/downloads/ 58 59[6] CodeSourcey 60 61http://www.mentor.com/embedded-software/codesourcery 62 63[7] Emdebian 64 65http://www.emdebian.org/crosstools.html 66
