[U-Boot] [PATCH v2 0/4] Fix default values for address and size cells

[U-Boot] [PATCH v2 0/4] Fix default values for address and size cells

[matthias.bgg at kernel.org]

From: Matthias Brugger <mbrugger@suse.com>

The libftd implementation of U-Boot is outdated with the
upstream project. Especially the default number of size-cells
was wrong. This series fixes this by backporting the corresponding
patches from the upstream project.

Changes since v1:
- fix spelling of U-Boot (patch 1 + 2 /4)
- add Reviewed-by tag (patch 1/4)
- fix the case of size-cells == 0 (patch 3/4)
- fix default address cells for livetree (patch 4/4)

v1 can be found here:
https://patchwork.ozlabs.org/patch/1137331/
https://patchwork.ozlabs.org/patch/1137330/

[U-Boot] [PATCH v2 1/4] libfdt: fdt_address_cells() and fdt_size_cells()

[matthias.bgg at kernel.org]

From: Matthias Brugger <mbrugger@suse.com>

Add internal fdt_cells() to avoid copy and paste. Fix typo in
fdt_size_cells() documentation comment.

This is based in upstream commit:
c12b2b0 ("libfdt: fdt_address_cells() and fdt_size_cells()")
but misses the test cases, as we don't implement them in U-Boot.

[U-Boot] [PATCH v2 2/4] libfdt: return correct value if #size-cells property is not present

[matthias.bgg at kernel.org]

From: Matthias Brugger <mbrugger@suse.com>

According to the device tree specification, the default value for
was not present.

This patch also makes fdt_address_cells() and fdt_size_cells() conform
to the behaviour documented in libfdt.h. The defaults are only returned
if fdt_getprop() returns -FDT_ERR_NOTFOUND, otherwise the actual error
is returned.

This is based on upstream commit:
aa7254d ("libfdt: return correct value if #size-cells property is not present")
but misses the test case part, as we don't implement them in U-Boot.

[U-Boot] [PATCH v2 3/4] libfdt: Allow #size-cells of 0

[matthias.bgg at kernel.org]

From: Matthias Brugger <mbrugger@suse.com>

The commit "libfdt: fdt_address_cells() and fdt_size_cells()" introduced
a bug as it consolidated code between the helpers for getting
be 0, and is frequently found so in practice for /cpus.  IEEE1275 only
requires implementations to handle 1..4 for #address-cells, although one
could make a case for #address-cells == #size-cells == 0 being used to
represent a bridge with a single port.

While we're there, it's not totally obvious that the existing implicit
cast of a u32 to int will give the correct results according to strict C,
although it does work in practice.  Straighten that up to cast only after
we've made our range checks.

This is based on upstream commit:
b8d6eca ("libfdt: Allow #size-cells of 0")
but misses the test cases,as we don't implement them in U-Boot.

According to the device tree specification, the default value for
#size-cells is 1, but fdt_size_cells() was returning 2 if this property
was not present.

BTW this series is a fix and I'd like to see it in v2019.10-rc5. I'm not sure
who is to take it, you or Tom.

[U-Boot] [PATCH v2 1/4] libfdt: fdt_address_cells() and fdt_size_cells()

[sjg at google.com]

From: Matthias Brugger <mbrugger@suse.com>

Add internal fdt_cells() to avoid copy and paste. Fix typo in
fdt_size_cells() documentation comment.

This is based in upstream commit:
c12b2b0 ("libfdt: fdt_address_cells() and fdt_size_cells()")
but misses the test cases, as we don't implement them in U-Boot.

Argh, you are right, I accidentally deleted one line from the commit message.
The correct paragraph should read like this:

<snip>
According to the device tree specification, the default value for
#size-cells is 1, but fdt_size_cells() was returning 2 if this property
was not present.
</snip>

BTW this series is a fix and I'd like to see it in v2019.10-rc5. I'm not sure
who is to take it, you or Tom.

I just looked through the upstream U-Boot commit log and don't see them queued
for 2019.10-rc5
Do I understand correctly that you are planning to merge them after 2019.10 is
released. Correct?

I'm asking because without these patches the grub boot path for RPi4 with RAM >
1GB is 'broken', in the sense that the kernel will only see RAM size of 1GB.

I can keep them as backports in openSUSE, that's no problem, just wanted to know
what's your plan. And have a quick answer if someone asks on the mailinglist :)

Matthias
