Subject: [PATCH] rpi4: Update memory map to accommodate scb devices
|
|
|
|
|
|
|
|
|
|
Some of the devices(for instance, pcie and gnet controller) sitting on
|
|
|
|
|
SCB bus falls behind/below the memory range that we currenty have.
|
|
|
|
|
|
|
|
|
|
This patch updates the memory range to map those devices correctly.
