The base address of the second memory region on the lager
board is 0x140000000. Update the tag used in the dts file accordingly.
This is a documentation fix and should have no run-time affect.
This problem was introduced when the second memory region
was added to the lager dts file by 62bc32a2573c4219
("ARM: shmobile: Include all 4 GiB of memory on Lager)"
in v3.14.

That should even be "memory@1,40000000".

Two comma-separated 32bit values in the case
where a memory range starts above 4Gb?
If so it looks like this will be the first user of that syntax
(I don't see any in linux-next today).
I do however see several users of memrory@64bit_value.
Mostly other renesas fds files; ecx-2000.dts being the exception.
Should they be fixed too?
$ find -name "*.dts" | xargs grep memory@[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]
./arch/arm/boot/dts/r8a7791-henninger.dts: memory@200000000 {

Yes. As #address-cells is 2, there should be two values after the "@"
(the first one may be optional if it's zero, I don't know for sure?)

No, "git grep '@.*,' -- arch/arm/boot/dts" shows several users.
Not all of them are 64-bit memory addresses, but some are.
