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

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

blinking etc. The functions that are hooked into this cyclic list should
be small timewise as otherwise the execution of the other code that relies
on a high frequent polling (e.g. UART rx char ready check) might be
-delayed too much. To detect cyclic functions with a too long execution
-time, the Kconfig option `CONFIG_CYCLIC_MAX_CPU_TIME_US` is introduced,
-which configures the max allowed time for such a cyclic function. If it's
-execution time exceeds this time, this cyclic function will get removed
-from the cyclic list.
