Hi Raymond,
I haven't managed to root cause it yet, but this series seems to make
the RB3 Gen 2 Qualcomm board hang during relocation.
How early post-relocation does any code here get called?

Motivations for changes:
Current SMBIOS library and command-line tool is not fully matching with
the requirements:
1. Missing support for other mandatory types (#7, #9, #16, #17, #19).
2. Only a few platforms support SMBIOS node from the device tree.
3. Values of some fields are hardcoded in the library other than fetching
from the device hardware.
4. Embedded data with dynamic length is not supported (E.g. Contained
Object Handles in Type #2 and Contained Elements in Type #3)
Changes:
1. Refactor the SMBIOS library and command-line tool to better align with
the SMBIOS spec.
2. Create an arch-specific driver for all aarch64-based platforms to fetch
SMBIOS private data from the device hardware.
3. Create a sysinfo driver to poppulate platform SMBIOS private data.
4. Put device tree SMBIOS node as a fallback solution when SMBIOS data is
missing from sysinfo driver.
5. Add support for Type #7 (Cache Information) and link its handles to
Type #4.
Once this patch is acceptted, subsequent patch sets will add other missing
types (#9, #16, #17, #19).
