I am on the fence on this one. On the one hand it makes sense in that
the kernel is usable without a "mem=256M..." command line option on
default configured platforms. Users that have upgraded the memory can
pass a "mem=512M..." to use their extra memory. However, it still
seems that this will appear as a regression to any current 512M
platforms that are not passing a command line option, and a "don't
care" to everyone who must be passing "mem=256M..." to get a
functional platform.
Hmm... can you say a bit more about this comment "solving this issue will help
also people porting the d-i on the device." [1] That might help tip the balance.
Thanks,
Dan
