doc: Migrate Renesas board docs to rst
Some of the information in README.rmobile is obsolete, references defconfigs which no longer exist in u-boot or has broken links. The information which is still relevant is moved into the reStructuredText documentation under `doc/board/renesas`, and `doc/README.rmobile` is dropped. The list of boards in `doc/board/renesas` is converted into a table so it's easier to see which defconfig to use. The list is expanded based on reviewing the current u-boot code and the contents of the eLinux wiki [1] [2].

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.
