firmware: ti_sci: fix the secure_hdr in do_xfer

The ti_sci driver in U-Boot has support for secure_msg as part of it's
do_xfer function. This let's U-boot send secure messages during boot up.

The protocol to send such secure messages is described as part of the
struct ti_sci_secure_msg_hdr. As part of this, there are 2 fields for
checksum and reserved that occupy the first 4 bytes of any secure
message. This is called as the secure_hdr.

As of now, the secure_hdr needs to be 0 init-ed before sending secure
messages. However the existing code was never putting the zero-inited vars
into the secure_buf, leading to possibility of the first 4 bytes of
secure_buf being possibly garbage.

Fix this by initialising the secure_hdr itself to the secure_buf
location, thus when we make secure_hdr members 0, it automatically ensures
the first 4 bytes of secure_buf are 0.

Sean Anderson [Sat, 16 Dec 2023 19:38:43 +0000 (14:38 -0500)]
clk: Document clk_ops return codes and behavior

Currently, clock consumers cannot take any programmatic action based on the
return code of a clock function. This is because there is no
standardization, and generally no way of separating e.g. "there was a major
problem setting the rate for this clock" which usually should not be
recovered from, from "this clock doesn't support setting its rate" or "this
clock doesn't support *this* rate" which could be absolutely fine depending
on the driver.

This commit aims to standardize the acceptable codes which may be returned
from clock operations. In general,

- ENOSYS should be returned when an operation is not supported for a
  particular clock.
- ENOENT may be returned if the clock ID is invalid. However, it is
  encouraged to move any checks to request() to reduce code duplication.
- EINVAL should be returned for logical errors only (such as requesting an
  invalid rate).

Each function has had specific guidance added for when to return each error
code. This is just guidance for now; most of the clock subsystem does not
yet conform to this standard. However, it is expected that new clock
drivers return these error codes.

Additionally, this commit adds expected behavior for each of the clock
operations. I believe these should be mostly straightforward and correspond
to existing behavior. I remember not understanding what the expected
invariants were for several clock functions, so hopefully this should help
out new driver authors. In the future, some of these invariants could be
checked via an optional config option.
