Subject: [PATCH 1/2] smbios: Simplify reporting of unknown values
If a value is not valid during the DT or SYSINFO parsing, we explicitly
set that to "Unknown Product" and "Unknown" for the product and
manufacturer respectively. It's cleaner if we move the checks insisde
smbios_add_string() and always report "Unknown" regardless of the missing
field.

Subject: [PATCH 2/2] smbios: Fallback to the default DT if sysinfo nodes are
missing
In order to fill in the SMBIOS tables U-Boot currently relies on a
"u-boot,sysinfo-smbios" compatible node. This is fine for the boards
that already include such nodes. However with some recent EFI changes,
the majority of boards can boot up distros, which usually rely on
things like dmidecode etc for their reporting. For boards that
lack this special node the SMBIOS output looks like:
System Information
Manufacturer: Unknown
Product Name: Unknown
Version: Unknown
Serial Number: Unknown
UUID: Not Settable
Wake-up Type: Reserved
SKU Number: Unknown
Family: Unknown
This looks problematic since most of the info are "Unknown". The DT spec
specifies standard properties containing relevant information like
'model' and 'compatible' for which the suggested format is
<manufacturer,model>. So let's add a last resort to our current
smbios parsing. If none of the sysinfo properties are found, we can
scan the root node for 'model' and 'compatible'.

If a value is not valid during the DT or SYSINFO parsing, we explicitly
set that to "Unknown Product" and "Unknown" for the product and
manufacturer respectively. It's cleaner if we move the checks insisde
smbios_add_prop_si() and provide an alternative string in case the
primary is NULL or empty

node is NULL and replace smbios_add_string() calls with
smbios_add_prop_si(ctx, NULL, ....)
Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org>

Changes since v2:
- refactor even more code and remove the smbios_add_string calls from the
main code. Instead use smbios_add_prop() foir everything and add a
default value, in case the parsed one is NULL or emtpy
Changes since v1:
- None

In order to fill in the SMBIOS tables U-Boot currently relies on a
"u-boot,sysinfo-smbios" compatible node. This is fine for the boards
that already include such nodes. However with some recent EFI changes,
the majority of boards can boot up distros, which usually rely on
things like dmidecode etc for their reporting. For boards that
lack this special node the SMBIOS output looks like:
System Information
Manufacturer: Unknown
Product Name: Unknown
Version: Unknown
Serial Number: Unknown
UUID: Not Settable
Wake-up Type: Reserved
SKU Number: Unknown
Family: Unknown
This looks problematic since most of the info are "Unknown". The DT spec
specifies standard properties containing relevant information like
'model' and 'compatible' for which the suggested format is
<manufacturer,model>. Unfortunately the 'model' string found in DTs is
usually lacking the manufacturer so we can't use it for both
'Manufacturer' and 'Product Name' SMBIOS entries reliably.
So let's add a last resort to our current smbios parsing. If none of
the sysinfo properties are found, scan for those information in the
root node of the device tree. Use the 'model' to fill the 'Product
Name' and the first value of 'compatible' for the 'Manufacturer', since
that always contains one.
pre-patch:
Handle 0x0001, DMI type 1, 27 bytes
System Information
Manufacturer: Unknown
Product Name: Unknown
Version: Unknown
Serial Number: 100000000bb24ceb

and post patch:

System Information
Manufacturer: raspberrypi

Simon, I'll work with tou on the refactoring you wanted and
remove the EFI requirement of SMBIOS in !x86 platforms.
Since this code has no tests, I'll add some once the refactoring
is done
Changes since v2:
- Spelling mistakes
- rebase on top of patch #1 changes
Changes since v1:
- Tokenize the DT node entry and use the appropriate value instead of
the entire string
- Removed Peters tested/reviewed-by tags due to the above
