The current bloblist pointer and size can be retrieved from global
data, so we don't need to pass them from the function arguments.
This change also help to remove all external access of gd->bloblist

Instead of expecting the bloblist total size to be the same as the
pre-allocated buffer size, practically we are more interested in
whether the pre-allocated buffer size is bigger than the bloblist
total size.

Pull request smbios-2024-04-rc2
* In smbios command
- write 'Not Specified' for missing strings
- show correct table size for SMBIOS2.1 entry point
- adjust formatting of handle numbers
- add missing colon after UUID
* In generated SMBIOS table
- avoid introducing 'Unknown' string for missing properties
- provide RISC-V vendor ID in the type 4 structure
- provide the correct chassis handle in structure type 2
* Rename Structure Table Maximum Size field in SMBIOS 3 entry point
In the SMBIOS 3 entry point the Structure Table Maximum Size field was
incorrectly named max_struct_size. A Maximum Structure Size field only
exists in the SMBIOS 2.1 entry point and has a different meaning.
Call the Structure Table Length field table_maximum_size.

Only the SMBIOS 2.1 entry point has a field for the maximum structure size.
As we have switched to an SMBIOS 3 entry point remove the superfluous

The SMBIOS table size for SMBIOS2.1 entry points is in field 'Structure
Table Length' (offset 0x16) and not in field 'Maximum Structure Size'
(offset 0x08).
Rename the receiving variable max_struct_size to table_maximum_size
to avoid future confusion.

For RISC-V CPUs the SMBIOS Processor ID field contains
the Machine Vendor ID from CSR mvendorid.
Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com>
The SMBIOS specification describes: "If a string field references no string,
a null (0) is placed in that string field."
Accordingly we should avoid writing a string "Unknown" to the SMBIOS table.
dmidecode displays 'Not Specified' if the string number is 0.
Commit 00a871d34e ("smbios: empty strings in smbios_add_string()")
correctly identified that strings may not have length 0 as two
consecutive NULs indentify the end of the string list. But the suggested
solution did not match the intent of the SMBIOS specification.

When no string is present in a table, next_ptr points to the same
location as eos. When calculating the string table length, we would only
reserve one \0. By spec a SMBIOS table has to end with two \0\0 when no
strings a present.

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.
