PS8, Line 177: get_option('rpmc').allowed()
> So, I downloaded the patch locally, to try and build it, and discover something. […]

I found the trace where current minimum 0.56.0 comes from:

In this patch https://review.coreboot.org/c/flashrom/+/73361 there is a link (in the first comment) that Debian Bullseye ships 0.56.2
https://packages.debian.org/bullseye/meson

And maybe we can talk about upgrading the minimum, but I definitely don't want to hold this patch for that. I would rather change it too use the "old-style" construction (get_option('rpmc').auto() or get_option('rpmc').enabled()) and get this merged.
If later we upgrade the meson version, we will upgrade to isAllowed() everywhere.

So, I suggest to change the lines 177-181 to

```
if (get_option('rpmc').auto() or get_option('rpmc').enabled()) and libcrypto.found()
    add_project_arguments('-DCONFIG_RPMC_ENABLED=1', language : 'c')
    srcs += 'rpmc.c'
    deps += libcrypto
endif
```
