/*
* Note that recent version of the device tree compiler (starting with
* version 1.4.2) warn about this node containing a reg property, but
* missing a unit-address. However, the bootloader on these Chromebook
* devices relies on the full name of this node to be exactly /memory.
* Adding the unit-address causes the bootloader to create a /memory
* node and write the memory bank configuration to that node, which in
* turn leads the kernel to believe that the device has 2 GiB of
* memory instead of the amount detected by the bootloader.
*
* The name of this node is effectively ABI and must not be changed.
