OE uses qemumips to simulate a Malta board by default.
As upstream qemu introduced:
https://git.qemu.org/?p=qemu.git;a=commit;h=94c2b6aff43cdfcfdfb552773a6b6b973a72ef0b
The Malta board can support up to 2GiB of RAM which should
be able to boot a Linux kernel built with CONFIG_HIGHMEM
enabled and passing "-m 2048" to QEMU and appending the
following kernel parameters:
...
mem=256M@0x0 mem=256M@0x90000000 mem=1536M@0x20000000
...
But the following commit in kernel broke above mem=X@Y setting
which added the memory as reserved memory area.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=73fbc1eba7ffa3bf0ad12486232a8a1edb4e4411

commit 73fbc1eba7ffa3bf0ad12486232a8a1edb4e4411
Author: Marcin Nowakowski <marcin.nowakowski@imgtec.com>
Date: Wed Nov 23 14:43:49 2016 +0100
MIPS: fix mem=X@Y commandline processing
...
So remove `mem=*' to disable user-defined physical RAM map
which let kernel itself caculates memory ranges.
