1Summary 2======= 3 4This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1] 5and Cortex-A9/A53/A57 based R-Car[2] family of SoCs. Renesas's RMOBILE/R-Car SoC 6family contains an ARM Cortex-A9/A53/A57. 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* Renesas Electronics Salvator-X M3 15* Renesas Electronics Salvator-XS H3 ES2.0+ 16* Renesas Electronics ULCB M3 / H3 ES2.0+ 17 18Toolchain 19========= 20 21Either ARMv7 toolchain for 32bit Cortex-A9 systems or ARMv8 (aarch64) 22toolchain for 64bit Cortex-A53/A57 systems. Currently we compile the 2332bit systems with -march=armv5 to allow more compilers to work. (For 24U-Boot code this has no performance impact.) 25 26Currently, ELDK[5], Linaro[6], CodeSourcery[7] and Emdebian[8] supports 27ARMv7. Modern distributions also contain ARMv7 and ARMv8 crosstoolchains 28in their package feeds. 29 30Build 31===== 32 33* KZM-A9-GT 34 35 make kzm9g_config 36 make 37 38* Armadillo-800-EVA 39 40 make armadillo-800eva_config 41 make 42 43 Note: Armadillo-800-EVA's U-Boot supports booting from SDcard only. 44 Please see "B.2 Appendix B Boot Specifications" in hardware manual. 45 46* Lager 47 48 make lager_config 49 make 50 51* Koelsch 52 53 make koelsch_config 54 make 55 56* Salvator-X M3 57 58 make r8a7796_salvator-x_defconfig 59 make 60 61* Salvator-XS H3 ES2.0 62 63 make r8a7795_salvator-x_defconfig 64 make 65 66* ULCB M3 67 68 make r8a7796_ulcb_defconfig 69 make 70 71* ULCB H3 ES2.0 72 73 make r8a7795_ulcb_defconfig 74 make 75 76Links 77===== 78 79[1] Renesas RMOBILE: 80 81http://am.renesas.com/products/soc/assp/mobile/r_mobile/index.jsp 82 83[2] Renesas R-Car: 84 85http://am.renesas.com/products/soc/assp/automotive/index.jsp 86 87[3] KZM-A9-GT 88 89http://www.kmckk.co.jp/kzma9-gt/index.html 90 91[4] Armadillo-800-EVA 92 93http://armadillo.atmark-techno.com/armadillo-800-EVA 94 95[5] ELDK 96 97http://www.denx.de/wiki/view/ELDK-5/WebHome#Section_1.6. 98 99[6] Linaro 100 101http://www.linaro.org/downloads/ 102 103[7] CodeSourcey 104 105http://www.mentor.com/embedded-software/codesourcery 106 107[8] Emdebian 108 109http://www.emdebian.org/crosstools.html 110
