Keeping dts/dtb in sync with latest kernel ( sopc2dts, boardinfo xml)

Hi John,

I managed to get a booting kernel in the meantime.

I posted a short overview of what I did in the rocketboards mailinglist (http://lists.rocketboards.org/pipermail/rfi/2014-february/001341.html)

I don't know if this is the perfect way but in case someone else wants to do this here is how I got there (also thanks to Dalon W.):

- I used the linux-socfpga git repository for building a kernel

* make ARCH=arm CROSS_COMPILE=xxx/gcc-linaro-arm-linux-gnueabihf-4.7-2012.11-20121123_linux/bin/arm-linux-gnueabihf- socfpga_defconfig

* make ARCH=arm CROSS_COMPILE=xxx/gcc-linaro-arm-linux-gnueabihf-4.7-2012.11-20121123_linux/bin/arm-linux-gnueabihf- uImage LOADADDR=0x8000

- And for building the modules

* make ARCH=arm CROSS_COMPILE=xxx/gcc-linaro-arm-linux-gnueabihf-4.7-2012.11-20121123_linux/bin/arm-linux-gnueabihf- modules

* make ARCH=arm CROSS_COMPILE=xxx/gcc-linaro-arm-linux-gnueabihf-4.7-2012.11-20121123_linux/bin/arm-linux-gnueabihf- INSTALL_MOD_PATH=xxx/rootfspatch/ modules_install

- I used the rootfs from the yocto release, and added the modules generated by the previous step to that rootfs

- I merged my old 3.9 dts with the socfpga(_cyclone5)(_socdk).dts(i) files from the 3.13 kernel and generated the dtb from it

- I had to modify 3.13 dw_mmc-socfpga.c with some 3.9 code to add mci_writel(host, PWREN, pwr_en); to power on / keep powered the SD card [probably not the ideal solution]

But now I am running into different problems with the 3.13 kernel so I am not sure my upgrade efforts were worth it ;p
