18 * Note that recent version of the device tree compiler (starting with
19 * version 1.4.2) warn about this node containing a reg property, but
20 * missing a unit-address. However, the bootloader on these Chromebook
21 * devices relies on the full name of this node to be exactly /memory.
22 * Adding the unit-address causes the bootloader to create a /memory
23 * node and write the memory bank configuration to that node, which in
24 * turn leads the kernel to believe that the device has 2 GiB of
25 * memory instead of the amount detected by the bootloader.
26 *
27 * The name of this node is effectively ABI and must not be changed.
