Philippe Reynes f66d4b05e1 board: Add Qemu SH4 r2d configuration
[ Thomas:

   * renamed sh4_defconfig to qemu_sh4_r2d_defconfig, for consistency
     with other Qemu platforms supported
   * renamed board/qemu/sh4 to board/qemu/sh4-r2d
   * minor fixes in the readme.txt
   * remove useless statements in the minimal defconfig
   * switch to a fixed kernel version instead of "same as headers"

This little documentation explains how to build a kernel and a rootfs
for qemu with sh4 architecture.
1) Select qemu sh4 configuration and compile it :
make sh4_defconfig
make all
2) Run qemu-system-sh4 with the kernel and rootfs previously generated
It's recommended to use a git release for qemu (the current stable
version has framebuffer display issues). If you want to avoid building
all target, you can use this option on qemu configure :
--target-list=sh4-softmmu
The command is :
qemu-system-sh4 -M r2d -kernel output/images/zImage -drive file=output/images/rootfs.ext2,if=ide,format=raw -append root=/dev/sda console=ttySC1,115200 noiotrap
