dpaa2_mac_is_type_fixed() is a header with no implementation and no
callers, which is referenced from the documentation though. It can be
deleted.
On the other hand, it would be useful to reuse the code between
dpaa2_eth_is_type_phy() and dpaa2_switch_port_is_type_phy(). That common
code should be called dpaa2_mac_is_type_phy(), so let's create that.
The removal and the addition are merged into the same patch because,
in fact, is_type_phy() is the logical opposite of is_type_fixed().

To read from a region, user space must currently request a new snapshot of
the region and then read from that snapshot. This can sometimes be overkill
if user space only reads a tiny portion. They first create the snapshot,
then request a read, then destroy the snapshot.
For regions which have a single underlying "contents", it makes sense to
allow supporting direct reading of the region data.
Extend the DEVLINK_CMD_REGION_READ to allow direct reading from a region if
requested via the new DEVLINK_ATTR_REGION_DIRECT. If this attribute is set,
then perform a direct read instead of using a snapshot. Direct read is
mutually exclusive with DEVLINK_ATTR_REGION_SNAPSHOT_ID, and care is taken
to ensure that we reject commands which provide incorrect attributes.
Regions must enable support for direct read by implementing the .read()
callback function. If a region does not support such direct reads, a
suitable extended error message is reported.

Even though the devices have very little in common beside the name and
the main "switch" feature, Marvell Prestera switch family is also
composed of PCI-only devices which can receive additional static
properties, like nvmem cells to point at MAC addresses, for
instance. Let's describe them.

Even though this description is not used anywhere upstream (no matching
driver), while on this file I decided I would try a conversion to yaml
in order to clarify the prestera family description.
I cannot keep the nodename dfx-server@xxxx so I switched to dfx-bus@xxxx
which matches simple-bus.yaml. Otherwise I took the example context from
the only user of this compatible: armada-xp-98dx3236.dtsi, which is a
rather old and not perfect DT.

This reverts commit 40acc05271abc2852c32622edbebd75698736b9b.
marvell,prestera.txt is an old file describing the old Alleycat3
standalone switches. The commit mentioned above actually hacked these
bindings to add support for a device tree property for a more modern
version of the IP connected over PCI, using only the generic compatible
in order to retrieve the device node from the prestera driver to read
one static property.
The problematic property discussed here is "base-mac-provider". The
original intent was to point to a nvmem device which could produce the
relevant nvmem-cell. This property has never been acked by DT
maintainers and fails all the layering that has been brought with the nvmem
bindings by pointing at a nvmem producer, bypassing the existing nvmem
bindings, rather than a nvmem cell directly. Furthermore, the property
cannot even be used upstream because it expected the ONIE tlv driver to
produce a specific cell, driver which used nacked bindings and thus was
never merged, replaced by a more integrated concept: the nvmem-layout.
So let's forget about this temporary addition, safely avoiding the need
for any backward compatibility handling. A new (yaml) binding file will
be brought with the prestera bindings, and there we will actually
include a description of the modern IP over PCI, including the right way
to point to a nvmem cell.

Kfuncs currently support specifying the KF_TRUSTED_ARGS flag to signal
to the verifier that it should enforce that a BPF program passes it a
"safe", trusted pointer. Currently, "safe" means that the pointer is
either PTR_TO_CTX, or is refcounted. There may be cases, however, where
the kernel passes a BPF program a safe / trusted pointer to an object
that the BPF program wishes to use as a kptr, but because the object
does not yet have a ref_obj_id from the perspective of the verifier, the
program would be unable to pass it to a KF_ACQUIRE | KF_TRUSTED_ARGS
kfunc.
The solution is to expand the set of pointers that are considered
trusted according to KF_TRUSTED_ARGS, so that programs can invoke kfuncs
with these pointers without getting rejected by the verifier.
There is already a PTR_UNTRUSTED flag that is set in some scenarios,
such as when a BPF program reads a kptr directly from a map
without performing a bpf_kptr_xchg() call. These pointers of course can
and should be rejected by the verifier. Unfortunately, however,
PTR_UNTRUSTED does not cover all the cases for safety that need to
be addressed to adequately protect kfuncs. Specifically, pointers
obtained by a BPF program "walking" a struct are _not_ considered
PTR_UNTRUSTED according to BPF. For example, say that we were to add a
kfunc called bpf_task_acquire(), with KF_ACQUIRE | KF_TRUSTED_ARGS, to
acquire a struct task_struct *. If we only used PTR_UNTRUSTED to signal
that a task was unsafe to pass to a kfunc, the verifier would mistakenly
allow the following unsafe BPF program to be loaded:
SEC("tp_btf/task_newtask")
int BPF_PROG(unsafe_acquire_task,
struct task_struct *task,
u64 clone_flags)
{
struct task_struct *acquired, *nested;
nested = task->last_wakee;
/* Would not be rejected by the verifier. */
acquired = bpf_task_acquire(nested);
if (!acquired)
return 0;
bpf_task_release(acquired);
return 0;
}
To address this, this patch defines a new type flag called PTR_TRUSTED
which tracks whether a PTR_TO_BTF_ID pointer is safe to pass to a
KF_TRUSTED_ARGS kfunc or a BPF helper function. PTR_TRUSTED pointers are
passed directly from the kernel as a tracepoint or struct_ops callback
argument. Any nested pointer that is obtained from walking a PTR_TRUSTED
pointer is no longer PTR_TRUSTED. From the example above, the struct
task_struct *task argument is PTR_TRUSTED, but the 'nested' pointer
obtained from 'task->last_wakee' is not PTR_TRUSTED.
A subsequent patch will add kfuncs for storing a task kfunc as a kptr,
and then another patch will add selftests to validate.

GSI firmware for IPA must be loaded during initialization, either by
the AP or by the modem. The loader is currently specified based on
whether the Boolean modem-init property is present.
Instead, use a new property with an enumerated value to indicate
explicitly how GSI firmware gets loaded. With this in place, a
third approach can be added in an upcoming patch.
The new qcom,gsi-loader property has two defined values:
- self: The AP loads GSI firmware
- modem: The modem loads GSI firmware
The modem-init property must still be supported, but is now marked
deprecated.
Update the example so it represents the SC7180 SoC, and provide
examples for the qcom,gsi-loader, memory-region, and firmware-name
properties.
