We want to encourage people to use an allocated bloblist since it is
more flexible than a fixed one. Make this the default, being sure not to
change existing users.
The unit tests require BLOBLIST_FIXED so add a dependency in the
Makefile to avoid build errors.

In many cases it is useful to get the address of a buffer, e.g. when
booting from it. Add a function to handle this.

Some header files included on the host are moving to use abuf, so adjust
the header-inclusion to bring in size_t correctly.

Enabling the option by default for the sandbox in cmd/Kconfig and for
x86 in arch/Kconfig is confusing. Please, use the same approach for all
concerned architectures.
Why do we need symbol CMD_MEMINFO_MAP? The meminfo command is worthless
without it. Both the greeting header and bdinfo already show the memory
size. Can we remove that over-engineering?
Sending standalone patches separately from a bulky patch series would
avoid hesitation to review and merge (see Tom's mail).
Best regards
Heinrich

I have no objection to that, but please check with Tom and Ilias[1] [2]

Well, thank you for reviewing. I'm going to figure out some tooling to
help, when I get a chance. Then I hope to be able to keep track of
lots of independent patches. Tom has suggested that I just send less,
as well. Another solution might be for me to adopt several aliases so
I am three different people?
Regards,
Simon

At some point it would be nice to have the ofnode API automatically
expand the tree as required, to accommodate new nodes. For now, expand
the default size so that UPL can be supported.

Update ofnode_add_subnode() and ofnode_add_prop() to return a suitable
error when space is exhausted in the FDT. This makes it easier to see
what is going wrong.

This function is really just getting the data. The size comes along for
the ride. In fact this function is only reliable way to obtain the data
for an image in a FIT, since the FIT may use external data.
Rename it to fit_image_get_data()

This function uses separate arguments for data and size. Use the new
abuf instead, so that they are paired and in one place. In some cases it
also saves an argument, thus potentially reducing code size.
Move the prototype to the header file while here.

Use this function instead of fit_image_get_emb_data() data, since it
works will FITs that use external data.

This function uses separate arguments for data and size. Use the new
abuf instead, so that they are paired and in one place. In some cases it
also saves an argument, thus potentially reducing code size.
Move the prototype to the header file while here.

QEMU always gets its devicetree from the OF_BOARD mechanism so we should
not depend on !BLOBLIST here.
The logic of PRIOR_STAGE is quite a mess, unfortuantely. We should rely
only standard passage to receive things from the prior stage. QEMU
should implement standard passage to provide its devicetree to U-Boot
However Linaro has blocked my patch to provide devicetree additions[1],
so little breath should be held in respect of either change.

QEMU can have its own internal ACPI and SMBIOS tables. At present U-Boot
copies out the SMBIOS tables but points directly to the ACPI ones.
The ACPI tables are not aligned on a 4KB boundary, which means that UPL
cannot use them directly, since it uses a reserved-memory node for the
tables and that it assumed (by EDK2) to be 4KB-aligned.
On x86, QEMU completely takes over the generation of these tables, thus
making it difficult to use any common code.
Adjust the logic to fit within the existing table-generation code. Use a
bloblist always and ensure that the ACPI tables is placed in an aligned
region. Set a size of 8K for QEMU. This does not actually put all the
tables in one place, for QEMU, since it currently adds a pointer to the
tables in QFW.
On ARM, enable bloblist so that SMBIOS tables can be added to the
bloblist.

The space here is quite tight and there is plenty of room in the ROM.
Move SPL earlier to allow for expansion.

Pull out the code which creates a new memory-node into its own function,
since several functions have similar logic.

than a real payload. Add a check for this.
Eventually a real writer will be in place.

It is better and simpler to do this at the start, so that an uninited
data structure doesn't cause problems. Update upl_init() to set up the
remaining two alists and remove this from the reading/test code.

This will be useful in U-Boot proper, so move the code from spl_upl to
the generic spl_common file.
Tweak the compatible string for serial and make sure to use the UPL
values for I/O / memory, even though they currently happen to be the
same as is used by U-Boot.

If video is enabled we expect it to work. Avoid silent failure by adding
a panic if things go wrong.
Expand the SPL malloc-area for qemu-x86_64 to avoid a panic.

This isn't strictly needed, but with UPL we use the reserved-memory
nodes to indicate where the SMBIOS table is. Tianocore requires 4KB
alignment on these regions, so it is easier to adjust the alignment
to match.

Please, avoid using once SZ_4K and once 0x1000 when expressing the same
number.
If you want to go with SZ_4K, please, also change the ACPI table entry
to use SZ_16K and SZ_4K to be consistent.

This node should have tags indicating the size of the addresses it uses.
The existing add_root_props() function only serves to add these tags to
a node. Rename it and allow passing the target-node to the function.
Use this to add nodes to the root and reserved-memory nodes.

With 32-bit machines sometimes a 64-bit address needs to be provided.
For example, ISA I/O access is indicated by setting bit 32 of the base
address.
Update the existing type to use 64 bits and drop the 0x prefix on unit
addresses.
Fix a 'nennap' typo while here.

The convention is to set bit 32 to indicate an I/O access. Do this when
using an ISA serial port.

The latest UPL spec uses a compatible string for this node rather than
relying just on the node's name to indicate its purpose. Add one.

Name the functions decode_reg() since it operates on an entire 'reg'

This function currently processes things two different ways, so the
treatment of unit addresses differs depending on whether OF_LIVE is
enabled or not.
Rewrite it to use the ofnode API and add a test to check that unit
addresses can be matched correctly.
Unfortunately this increases code size by about 104 bytes on Thumb2,
mostly due to the extra logic in ofnode_name_eq(). We could fix that
by having two separate ofnode_name_eq() functions, only one of which
allows an @ sign in its parameter.

The spec has changed to use a unit address and reg property for this
value. Update the implementation to match. It is now possible to obtain
the size of the FIT as well as its address.
Add #address/size-cells properties as well.

The current implementation of images does not cover all the requirements
of the current, updated UPL spec. Add support for an entry address, the
offset of the image within the FIT as well as the load address and size,
which are subsumed into the new 'reg' property.
Support writing this information out to the UPL handoff.
Update SPL to handle the struct change as well.

This is more convenient than a for() loop, so update upl_write to use
this new feature.

The write_mem_node() function uses sizeof(64) when sizeof(u64) is
intended. This can cause an error due to the buffer-space being
exhausted.
Correct this.

So far we have not needed PCI information, but EDK2 does complain when
it is missing. Add the required structures, as a starting point.

When the serial port uses I/O ports, it is expected to be on an ISA bus.
Handle this by creating a suitable node and putting the serial port in
that node.
Add a reference to the serial port in the /chosen node.

Add a new 'upl exec' command which loads a payload, sets up the handoff
information and jumps to it.
This collects image information as the FIT's images are loaded.
With this, the size of the FIT is not known so is reported through UPL
as zero. Future work will address this.

Some UPL images such as EDK2 may change into 64-bit mode after starting.
Avoid a crash by always using the 64-bit machine QEMU. This seems to
have no ill effects for 32-bit code.

provided, to allow iterating on the payload, without changing U-Boot

Mark these as reserved memory-regions so that the payload can find the
tables. Remove the upl-params properties which are no-longer in the
spec. Add a compatible string instead.

Tianocore expects this property to specify the entry address. Add it
until it can be updated to follow the spec in this area, i.e. use an
'entry' property in the relevant upl-image node.

Since this is on top of your fork, and not mainline, and you aren't even
noting that in your cover letter it's probably not worth the time of
everyone you sent this to, to look at.

It applies to -next except for the QEMU script which you rejected. I
can't do anything about that. So I think you may have the
wrong end of the stick here.
The only thing I can think of is that the UPL series depends on
Raymond's bloblist patch [1]. But I was assuming that would be applied
at some point and I didn't want to resend someone else's patch. I
don't have it in the sjg tree either yet, as I was hoping he would
write a test. In fact I would very-much like people to write tests
(and docs if needed) without needing to be asked.
Regards,
Simon

A 60 part series that includes changes to something that was rejected,
and depends on a series from someone else that was changes requested,
and is again, 60+ patches, is not at all helpful. Please stop doing
this.

As I see it, my only alternatives were to:
a) resend Raymond's patch unchanged (with a note that it is merely for
convenience), or
b) not send it, knowing that his patch will likely be applied before this series
I chose b. The single, dependent patch is really not an issue, IMO.
I often send large series, e.g. [2]. Sometimes, as with UPL, there is
just an enormous amount of work to get through. I really don't like
combining patches just to reduce the patch count. But I can split of
the pre-req patches (about 30) so I'll do that for v2. Honestly, I was
just desperate to get some of the work sent out so it didn't die on
the vine.
BTW, please reconsider your objections to the qemu script. I think it
might make sense to convert it to Python at some point, but the
complexity of building images and running QEMU for different use cases
is such that a script makes a lot of sense.
Regards,
Simon
