Per the kconfig.rst:
A device should be listed [...] ``imply`` if (depending on
the QEMU command line) the board may or may not be started
without it.
This is the case with the NVDIMM device, so use the 'imply'
weak reverse dependency to select the symbol.
Uh.. It should definitely be possible to start a pseries machine
without NVDIMM. I would have guessed the same for PC.
Yes, this is what this patch does. With it we can build with:
CONFIG_NVDIMM=n
But with "imply" you could end up with a PSERIES that does not have
NVDIMM when also using --without-default-devices, couldn't you?
Not currently, because of the CONFIG_NVDIMM=y.
Why don't you use "select" instead of "imply" ?
Because as David said earlier:
"It should definitely be possible to start a pseries machine
without NVDIMM."
