armvirt: 32: enable CONFIG_ARM_LPAE
This is required for running armvirt_32 on QEMU 3.0 [1], otherwise the kernel will emit the following complaint and virtio-net-pci devices will fail to be initialized [ 1.124214] OF: PCI: host bridge /pcie@10000000 ranges: [ 1.125093] OF: PCI: IO 0x3eff0000..0x3effffff -> 0x00000000 [ 1.125942] OF: PCI: MEM 0x10000000..0x3efeffff -> 0x10000000 [ 1.126403] OF: PCI: MEM 0x8000000000..0xffffffffff -> 0x8000000000 [ 1.127748] pci-host-generic 4010000000.pcie: can't claim ECAM area [mem 0x10000000-0x1fffffff]: address conflict with /pcie@10000000 [mem 0x10000000-0x3efeffff] [ 1.129752] pci-host-generic: probe of 4010000000.pcie failed with error -16 Running QEMU with "-M virt,highmem=off" is an option, but "highmem" was only introduced as a default on flag since QEMU 2.5.0 and QEMU will fail and quit on encounter of unknown flags [1] Armv7 guest fails to boot with qemu-3.0.0-1, https://bugzilla.redhat.com/show_bug.cgi?id=1633328#c5 Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com>
