1Summary 2======= 3 4This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1] 5and R-Car[2]family of SoCs. Renesas's RMOBILE/R-Car SoC family contains an ARM 6Cortex-A9. 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 15Toolchain 16========= 17 18ARM Cortex-A9 support ARM v7 instruction set (-march=armv7a). 19But currently we compile with -march=armv5 to allow more compilers to work. 20(For U-Boot code this has no performance impact.) 21Because there was no compiler which is supporting armv7a not much before. 22Currently, ELDK[5], Linaro[6], CodeSourcey[7] and Emdebian[8] supports -march=armv7a 23and you can get. 24 25Build 26===== 27 28* KZM-A9-GT 29 30 make kzm9g_config 31 make 32 33* Armadillo-800-EVA 34 35 make armadillo-800eva_config 36 make 37 38 Note: Armadillo-800-EVA's U-Boot supports booting from SDcard only. 39 Please see "B.2 Appendix B Boot Specifications" in hardware manual. 40 41* Lager 42 43 make lager_config 44 make 45 46* Koelsch 47 48 make koelsch_config 49 make 50 51Links 52===== 53 54[1] Renesas RMOBILE: 55 56http://am.renesas.com/products/soc/assp/mobile/r_mobile/index.jsp 57 58[2] Renesas R-Car: 59 60http://am.renesas.com/products/soc/assp/automotive/index.jsp 61 62[3] KZM-A9-GT 63 64http://www.kmckk.co.jp/kzma9-gt/index.html 65 66[4] Armadillo-800-EVA 67 68http://armadillo.atmark-techno.com/armadillo-800-EVA 69 70[5] ELDK 71 72http://www.denx.de/wiki/view/ELDK-5/WebHome#Section_1.6. 73 74[6] Linaro 75 76http://www.linaro.org/downloads/ 77 78[7] CodeSourcey 79 80http://www.mentor.com/embedded-software/codesourcery 81 82[8] Emdebian 83 84http://www.emdebian.org/crosstools.html 85
