I think you have some trouble understanding the concept of industry
standard ;).  I guess you want this to become an industry standard.
Firmly https://xkcd.com/927/ territory if you ask me.

> UPL is designed to improve interoperability within the
> firmware industry, allowing mixing and matching of projects with less
> friction and fewer project-specific implementations. UPL is
> cross-platform, supporting ARM, x86 and RISC-V initially.
> 
> This series provides some initial support for this, targeting 0.9.1 and
> sandbox only.
> 
> Features still to come include:
> - Support for architectures
> - FIT validation
> - Handoff validation
> - Interoperability tests
> 
> This series is available at dm/uplb-working and requires the alist
> series at dm/alist-working[2]

> 
> Changes in v2:
> - Put the upl tests under their own subcommand to avoid bootstd init
> - Add a function to init the UPL process in SPL
> - Hang when something goes wrong, to avoid a broken boot
> - Add a runtime flag to enable UPL
> - Add a link to the spec
> - Add a link to the command
> - Support CI testing
> - Rework to use alist instead of fixed-length arrays
> 
> Simon Glass (21):
>   sandbox: Use const in os_jump_to_file()

>   test: Move some SPL-loading test-code into sandbox common
>   sandbox: Enable SPL_LOAD_BLOCK
>   fdt: Don't overwrite bloblist devicetree
>   sandbox: fdt: Avoid overwriting an existing fdt
>   sandbox: Return error code from read/write/seek
>   sandbox: Add ELF file to VPL u-boot.img
>   sandbox: Set up global_data earlier
>   upl: Add support for reading a upl handoff
>   upl: Add support for writing a upl handoff
>   upl: Add basic tests
>   upl: Add a command
>   upl: Add support for Universal Payload in SPL
>   spl: Plumb in the Universal Payload handoff
>   upl: Plumb in universal payload to the init process
>   sandbox_vpl: Enable Universal Payload
>   upl: Add initial documentation
>   sandbox: Add a flag to enable UPL
