The board support is a bit more useful with active networking.

Currently this just calls the zynq_mkimage script to stamp in the header
checksum. Can be extended to a proper multi-image build later on.

This requires a PBL to be build, but as the only supported Zynq board
already selects the PBL option in the defconfig there is no big change
to the previous status

Instead of generating a suitable image header with linker magic, move
all of this into zynq_mkimage. The configuration file format and parsing
is based on imx-image. This gets us one step further on the road to
proper multi-image support.

Currently Barebox does not support 2 stage loading on Zynq, so the
image must fit into the free OCRAM area. Add a check to the mkimage
tool to validate this.

Provide the DTB to allow devices to be probed from there,
instead of board code.

Both pclk and hclk are required clocks in the DT binding.
rx_clk and tx_clk are optional, but must be enabled if a system
has separate gates for them.

No functional change, just adjusting the Zynq code to common practise.

The clock controller is a subregion of the SLCR, use the real base
of this region for mapping the registers. This will allow to switch
to DT based probing later.

Ensure that both the powerdown and reset bits are cleared when the PLL
gets enabled, as any of those set would prevent the PLL from working.

Also add a status readback function, so the real status of the PLL is
reflected in the Barebox clock state.

The upstream Zynq 7000 DT describes the SLCR child devices physical
address as an offset within the SLCR. The driver thus needs to add
the SLCR base offset to the address before trying to map the MMIO
region.

Sync the clock enum with the clocks used by Linux and the DT binding.
Implement AMBA bus clocks and SPI and SDIO peripheral clocks and
register a DT clock controller, so the clocks can be looked up by
DT handle.

All the currently supported devices can now be probed
from the DT. Remove platform devices and switch to DT.

They aren't needed anymore, as all the Zynq devices now
use a DT based clock lookup.

Some SoCs are able to detect if they are booted from JTAG. Add the
enum value to be able to represent this as a valid bootsource.
