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:
- Missing support for other mandatory types (#7, #9, #16, #17, #19).
- Only a few platforms support SMBIOS node from the device tree.
- Values of some fields are hardcoded in the library other than fetching from the device hardware.
- Embedded data with dynamic length is not supported (E.g. Contained Object Handles in Type #2 and Contained Elements in Type #3)
Changes:
- Refactor the SMBIOS library and command-line tool to better align with the SMBIOS spec.
- Create an arch-specific driver for all aarch64-based platforms to fetch SMBIOS private data from the device hardware.
- Create a sysinfo driver to poppulate platform SMBIOS private data.
- Put device tree SMBIOS node as a fallback solution when SMBIOS data is missing from sysinfo driver.
- 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).
