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| SoC | Board | defconfig 11|===============+========================================+=================== 12| R8A73A0 | KMC KZM-A9-GT [3] | kzm9g_config 13| R8A7734 | Atmark-Techno Armadillo-800-EVA [4] | armadillo-800eva_config 14|===============+========================================+=================== 15| R8A7790 H2 | Renesas Electronics Lager | lager_defconfig 16| | Renesas Electronics Stout | stout_defconfig 17|---------------+----------------------------------------+------------------- 18| R8A7791 M2-W | Renesas Electronics Koelsch | koelsch_defconfig 19| | Renesas Electronics Porter | porter_defconfig 20|---------------+----------------------------------------+------------------- 21| R8A7792 V2H | Renesas Electronics Blanche | blanche_defconfig 22|---------------+----------------------------------------+------------------- 23| R8A7793 M2-N | Renesas Electronics Gose | gose_defconfig 24|---------------+----------------------------------------+------------------- 25| R8A7794 E2 | Renesas Electronics Alt | alt_defconfig 26| | Renesas Electronics Silk | silk_defconfig 27|===============+========================================+=================== 28| R8A7795 H3 | Renesas Electronics Salvator-XS ES2.0+ | r8a7795_salvator-x_defconfig 29| R8A7795 H3 | Renesas Electronics ULCB ES2.0+ | r8a7795_ulcb 30|---------------+----------------------------------------+------------------- 31| R8A7796 M3-W | Renesas Electronics Salvator-X | r8a7796_salvator-x_defconfig 32| R8A7796 M3-W | Renesas Electronics ULCB | r8a7796_ulcb 33|---------------+----------------------------------------+------------------- 34| R8A77965 M3-N | Renesas Electronics Salvator-XS | r8a77965_salvator-x_defconfig 35| R8A77965 M3-N | Renesas Electronics ULCB | r8a77965_ulcb 36|---------------+----------------------------------------+------------------- 37| R8A77970 V3M | Renesas Electronics Eagle | r8a77970_eagle_defconfig 38|---------------+----------------------------------------+------------------- 39| R8A77995 D3 | Renesas Electronics Draak | r8a77995_draak_defconfig 40'===============+========================================+=================== 41 42Toolchain 43========= 44 45Either ARMv7 toolchain for 32bit Cortex-A9 systems or ARMv8 (aarch64) 46toolchain for 64bit Cortex-A53/A57 systems. Currently we compile the 4732bit systems with -march=armv5 to allow more compilers to work. (For 48U-Boot code this has no performance impact.) 49 50Currently, ELDK[5], Linaro[6], CodeSourcery[7] and Emdebian[8] supports 51ARMv7. Modern distributions also contain ARMv7 and ARMv8 crosstoolchains 52in their package feeds. 53 54Build 55===== 56 57Locate defconfig in the table above. Then apply standard build procedure: 58 59 make <board>_defconfig 60 make 61 62 Note: Armadillo-800-EVA's U-Boot supports booting from SDcard only. 63 Please see "B.2 Appendix B Boot Specifications" in hardware manual. 64 65Links 66===== 67 68[1] Renesas RMOBILE: 69 70http://am.renesas.com/products/soc/assp/mobile/r_mobile/index.jsp 71 72[2] Renesas R-Car: 73 74http://am.renesas.com/products/soc/assp/automotive/index.jsp 75 76[3] KZM-A9-GT 77 78http://www.kmckk.co.jp/kzma9-gt/index.html 79 80[4] Armadillo-800-EVA 81 82http://armadillo.atmark-techno.com/armadillo-800-EVA 83 84[5] ELDK 85 86http://www.denx.de/wiki/view/ELDK-5/WebHome#Section_1.6. 87 88[6] Linaro 89 90http://www.linaro.org/downloads/ 91 92[7] CodeSourcey 93 94http://www.mentor.com/embedded-software/codesourcery 95 96[8] Emdebian 97 98http://www.emdebian.org/crosstools.html 99
