Hi!
This is mostly a repost of v3. Only changes are in 4/5.
The final image now gets always piped through zynq_mkimage. This is needed
anyway, so do it always.
This tool will eventually replace all the flash_header linker stuff, although
it is pretty simple on the Zynq.
Regards,
Steffen

Add basic support for the Xilinx Zynq-7000 EPP architecture.
The Zynq-7000 is an embedded processing platform that combines a Cortex A9
dualcore MPSoC with an Artix-7 FPGA.
Signed-off-by: Steffen Trumtrar <s.trumtrar@pengutronix.de>

Changes since v2:
- don't force serial driver in Kconfig
- remove MACH_HAS_LOWLEVEL_INIT
- use (void __iomem *) in debug_ll.h
- remove zynq_add_device inline function
- use resource_size_t instead of void *
- use __le32 consistently in zynq-flash-header.h
- remove useless flash_header_start section

To: barebox; +Cc: Steffen Trumtrar
This adds support for the clocktree on zynq7000 SoCs.
The patch is based on clocks.c from the larger patch
ARM: zynq: add suppport for Zynq 7000 SoC
by Josh Cartwright.
The driver in that patch is converted to a platform_driver and code to
enable plls was added.

The bootrom only reads an image if the correct checksum is present in the
header. The calculation is pretty simple:
sum over all words from 0x20 to 0x44
Two of this words are the image length. That is why the checksum can not be
calculated until barebox_image_size is known.
The easiest solution is a program that has to be run after make.

The Avnet ZedBoard is an evalboard with a Zynq-7020 based MPSoC.
There is also a Digilent ZedBoard, that is the same but only for
academic customers.

I have signed to barebox mailing list today and I see that in the right time.
It is little bit messy what you have sent.
It is mix of v2/v3/v4 patches where it is not clear which version I should try.
Can you please resend the whole patchset as v5?
Thanks,
Michal

Hi,
I'm actually not sure if I like the mix myself, but you gotta try stuff :-)
The series is the latest and greatest and some patches just didn't change.
But it seems to confuse more than it helps.
So, just take the series as is, please. Sascha is okay with the patches and
will take them (I hope he doesn't change his mind in the meantime :-))
Sorry for the confusion.
Regards,
Steffen

Interesting working style. From my point of view this is really problematic
because you it is just confusing. But ok if others are ok with this workflow.

Not sure how much we care here, but with the order of the patchset the
way it is, after this one, it will be possible to select the ZedBoard,
even though all of the other support files get added only in the last
patch.

One thing I found during my testing/debugging to be useful is to have a
way to turn off the flash header, to get a header-less barebox.bin I
could use JTAG to load on the board. (I realize I could have done used
it _with_ the flash header and set the PC up at 0x8c0, but this was
easier).
It would be nice if there was a headerless binary left as a build
artifact that could be used for this purpose.

I saw Sascha posted a patch removing these, so depending on when this
lands this may need cleaned up.

Yes. Sascha suggested to remove the flash_header and generate the whole
thing with the zynq_mkimage tool. But atm I don't really feel the need to
do so, as the header is simple in comparison to other SoCs. And as you
said, you can jump over the header.

Steffen
