zynq: More boards support

These changes are from u-boot-xlnx.git repo from git.xilinx.com and in addition of basic fdt support. This repo is well tested on xilinx zynq platform, hence pushing the same on upstream.

Excluded qspi and nand changes from previous series.

Please note that all this series available in u-boot-spi.git/master-xlnx repo.

Hi Jagannadha,

As the series was rebased tu u-boot/master, not u-boot-arm/master, all patches adding board support failed to apply properly due to boards.cfg differences.

I did resolve these manually, but at build-test time, all Zynq boards failed with "Makefile:11: *** Please define CONFIG_DEFAULT_DEVICE_TREE in your board header file. Stop." -- and were the only ones to do so.

Jagan, can you look into this and produce a v5 which can build on ARM?

Amicalement,

Albert.

Hi Albert,

Yes - I saw this i'll rebase your u-boot-arm/master then.

Actually build will successful when you give the dts at runtime while building u-boot like Linux style.

$ make DEVICE_TREE=<dts_file_name>
ex: make DEVICE_TREE=zynq-zc702

This is the reason I am not defining this on individual pre-board configs. I guess this could be fine, please comment.

Thanks,
Jagan.

Hi Jagan,

Boards in U-Boot are expected to build with commands

make <board>_config
make

or with

./MAKEALL <board>

I am therefore not fine with a board which fails when built as above.

Instead of explicitly specifying a DT in the build command line, just make this DT the default one, by following the advice in the error message above, and putting it in the config header files. Each board can (and will, I assume) have its own default DT.

This way, building the board by default will wok, an you will still be able to override the default DT by specifying a different one on the command line if you so wish or need.

Amicalement,

Albert.

... although powering on the board may fry it.

Amicalement,

Albert, shameless.
