Subject: [PATCH] ARM: dts: Expand PCIe space on BCM2711
|
|
|
|
Attempts to connect external GPUs to Compute Module 4's PCIe bus have
|
|
highlighted that the existing "outbound window" - the fraction of the
|
|
PCI address base that is appears in the host's memory map - is
|
|
restrictively small. Expand the window to a full 1GB.
