  1. Summary
  2. =======
  3. This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1]
  4. and Cortex-A9/A53/A57 based R-Car[2] family of SoCs. Renesas's RMOBILE/R-Car SoC
  5. family contains an ARM Cortex-A9/A53/A57.
  6. Currently the following boards are supported:

  39. Toolchain
  40. =========
  41. Either ARMv7 toolchain for 32bit Cortex-A9 systems or ARMv8 (aarch64)
  42. toolchain for 64bit Cortex-A53/A57 systems. Currently we compile the
  43. 32bit systems with -march=armv5 to allow more compilers to work. (For
  44. U-Boot code this has no performance impact.)
  45. Currently, ELDK[5], Linaro[6], CodeSourcery[7] and Emdebian[8] supports
  46. ARMv7. Modern distributions also contain ARMv7 and ARMv8 crosstoolchains
  47. in their package feeds.
  48. Build
  49. =====
  50. Locate defconfig in the table above. Then apply standard build procedure:
  51. make <board>_defconfig
  52. make
  53. Note: Armadillo-800-EVA's U-Boot supports booting from SDcard only.
  54. Please see "B.2 Appendix B Boot Specifications" in hardware manual.
