"...By default ZONE_DMA covers the 32-bit addressable memory
* unless restricted on specific platforms (e.g. 30-bit on Raspberry Pi 4). ..."
Is Pi5 ZONE_DMA also limited to 30-bit addressable memory?
Where in the raspberry pi os source code is it defined that ("if(Pi4) ZONE_DMA = range from xxxxxxxxxx - zzzzzzzzz"; //thats 30-bits range)
