Add tee node in SoC u-boot device trees. Use a kconfig entry to specify
load and entry addresses for the op-tee image in the respective
defconfig.

Hi Yannic,
Thanks for working on this.
Don't you need to protect this block with an #ifdef
CONFIG_IMX8M_OPTEE_LOAD_ADDR? I would expect binman to fail if it
doesn't find tee.bin and has an empty load/entry address.
Also, when I attempted this patch some time ago it was accepted but
failed CI which is something I never had time to figure out and
address. The failure had something to do with adding the Kconfig and
you should be able to find the discussion with a pointer to the
failure in your references above.
Did you make sure CI passes?
Best Regards,
Tim

I do not need to do that because the config is defined for all imx8m boards. If I didn't define a
default, the kconfig mechanism prompts for a value for the load addr.

I took a look at your patch before working on this series and to the best of my knowledge the
challenge was that you defined the kconfig for all boards and failed for other architectures or no
architecture in that particular case afaik. The solution is to define a default value, but obviously
it should at least be a valid address.
To illustrate, some of our (Phytec imx8m) boards have 1GiB RAM (up to 0x80000000) and for e.g. imx93
RAM starts at 0x90000000, the only good option is to put it in the imx8m Kconfig.

I did test the failed CI that Stefano highlighted at the time and that passes. For others I don't
know.

I think this would need to vary based on the platform. I think the
addresses may be different depending on Mini, Nano and Plus and also
dependent on the available SDRAM.

Indeed the address differs for platform (as the DRAM base address
does) and is also based on the DRAM size of the board. Here are my
notes for IMX8M:
The address is the link/load address for TEE that should match
BL32_BASE for the ATF (for imx8m) and CFG_TZDRAM_START for OPTEE. The
BL32_BASE is the same for imx8mm/n/p but it does depend on the size of
DRAM. The address should be the top 32MiB of DRAM but because U-Boot
is loading tee.bin from a FIT image into DRAM it needs to be a 32bit
address and thus needs to be adjusted down if you are on a board with
4GiB:
1GiB DRAM use 0x7e000000
2GiB DRAM use 0xbe000000
3GiB or larger use 0xfe000000

Tim

I agree the addresses may be different. To my knowledge you can take whatever (32bit) address you
want within addressable RAM as load address. I assume you are looking for sensible defaults here.
It appears to me the challenge is agreeing on a sensible value.
Do you have any suggestions?

On my Mini with 2GB of RAM, there are several definitions:
PHYS_SDRAM 0x40000000
PHYS_SDRAM_SIZE 0x80000000 /* 2GB DDR */
What we if did a calculation like:
PHYS_SDRAM + MIN(PHYS_SDRAM_SIZE, 0xc0000000) - 0x2000000
With 2 GB of RAM, it would be 0xbe000000
My Nano Board has the following:
PHYS_SDRAM 0x40000000
PHYS_SDRAM_SIZE 0x40000000
That calculation should return 7E000000.
I am not sure if we can do MIN and MAX functions in the precompiler,
but it would then cap the value to 0xfe000000

Math looks good to me, however I don't understand where we would put this in the source code.
How can we set this as default while having access to the macros?

As I don't think it is possible to implement the mechanic as you suggested, I would like to keep it
simple.
trusted-firmware-a also has default for BL32_BASE. I would like to set the OPTEE_LOAD_ADDR as they
are set in tf-a. This has the advantage that for users who don't change the default, they can rely
on it being consistent across projects.

You are already defining a default for IMX8M_OPTEE_LOAD_ADDR in the
mach-imx Kconf. You can drop the patches touching the defconfigs.

I would like to keep these patches as the default value is "only" there to get a functioning build.
To me it would seem there has been no thought put in to what the actual correct value would be if
left as default. Does that make sense?

Yes, this makes sense. Up to you, it was just a hint.
Well, it will become de facto standard if you put a default value into
the Kconfig regardless if there has been no thoughts on the best
location for it. Other boards will probably just follow and reuse it anyway.

Add documentation for the phyBOARD-Pollux i.MX 8M Plus on OP-TEE
integration.
Also add missing '-' to TF-A build instruction while at it.

Would it make sense to move these instructions into a more general
section, so they could be reused by other imx based boards as well?
Seems you missed to update imx8mm-phygate-tauri-l.rst

I have not put much thought into it. At first glance though, when reading the documentation for a
board I don't want to be redirected to other pages. So using an include comes to mind. Is that what
you had in mind as well?

Should be in the (next) patch for the imx8mm, as Tauri is based on phycore-imx8mm. Let me know if
you meant something else.

Yes, I was thinking about using includes to reduce doc duplication.

Ah! I missed that you change both files in the next patch.

Add instructions on how to build and package OP-TEE for the
phycore-imx8mm based boards. The build instructions are identical for
phyGATE-Tauri-L and phyBOARD-Polis.
Also fix missig '-' for TF-A build instructions.
