1 Summary 2 ======= 3 4 This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1] 5 and Cortex-A9/A53/A57 based R-Car[2] family of SoCs. Renesas's RMOBILE/R-Car SoC 6 family contains an ARM Cortex-A9/A53/A57. 7 8 Currently 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 |---------------+----------------------------------------+------------------- 36 | R8A77970 V3M | Renesas Electronics Eagle | r8a77970_eagle_defconfig 37 |---------------+----------------------------------------+------------------- 38 | R8A77995 D3 | Renesas Electronics Draak | r8a77995_draak_defconfig 39 '===============+========================================+=================== 40 41 Toolchain 42 ========= 43 44 Either ARMv7 toolchain for 32bit Cortex-A9 systems or ARMv8 (aarch64) 45 toolchain for 64bit Cortex-A53/A57 systems. Currently we compile the 46 32bit systems with -march=armv5 to allow more compilers to work. (For 47 U-Boot code this has no performance impact.) 48 49 Currently, ELDK[5], Linaro[6], CodeSourcery[7] and Emdebian[8] supports 50 ARMv7. Modern distributions also contain ARMv7 and ARMv8 crosstoolchains 51 in their package feeds. 52 53 Build 54 ===== 55 56 Locate defconfig in the table above. Then apply standard build procedure: 57 58 make <board>_defconfig 59 make 60 61 Note: Armadillo-800-EVA's U-Boot supports booting from SDcard only. 62 Please see "B.2 Appendix B Boot Specifications" in hardware manual. 63 64 Links 65 ===== 66 67 [1] Renesas RMOBILE: 68 69 http://am.renesas.com/products/soc/assp/mobile/r_mobile/index.jsp 70 71 [2] Renesas R-Car: 72 73 http://am.renesas.com/products/soc/assp/automotive/index.jsp 74 75 [3] KZM-A9-GT 76 77 http://www.kmckk.co.jp/kzma9-gt/index.html 78 79 [4] Armadillo-800-EVA 80 81 http://armadillo.atmark-techno.com/armadillo-800-EVA 82 83 [5] ELDK 84 85 http://www.denx.de/wiki/view/ELDK-5/WebHome#Section_1.6. 86 87 [6] Linaro 88 89 http://www.linaro.org/downloads/ 90 91 [7] CodeSourcey 92 93 http://www.mentor.com/embedded-software/codesourcery 94 95 [8] Emdebian 96 97 http://www.emdebian.org/crosstools.html 98
