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