The Raspberry Pi has either 256MB or 512MB of RAM. However, a portion is reserved for use by the VideoCore co-processor. The RPi DT contained a /memreserve/ statement to reserve that RAM. However, the exact amount of RAM used by the VideoCore is dynamic at boot-time; a firmware config file specifies the amount. As such, we can't hard-code the size in the DT. Remove the /memreserve/ statement. The bootloader is expected to adjust the /memory properties to reflect the RAM size the ARM CPU can use. Upstream U-Boot certainly does this, although I'm not sure that the basic firmware does if it boots the kernel directly; users may need to manually adjust their DT if not using U-Boot.
