If the user sets bootm_low and does not set bootm_size, u-boot will report the memory node in the flat device tree incorrectly. Instead of reporting the remaining size of memory, it will report the total available memory which is incorrect.
Specifically this fixes the situation when booting a relocatable kernel and the memory is reported as an offset and size in the device tree, and the size needs to be adjusted accordingly.

Parens not useful here and above.
