Subject: [PATCH] rpi5: add initial memory map for bcm2712
|
|
|
|
This includes:
|
|
* 1GB of RAM (from 4GB or 8GB total)
|
|
* AXI ranges (main peripherals)
|
|
|
|
When HDMI cable is plugged in at boot time firmware will
|
|
insert "simple-framebuffer" device into devicetree and will
|
|
shrink first memory region to 0x3f800000UL. Board setup then
|
|
will properly reserve framebuffer region.
|
|
|
|
When no HDMI cable is plugged in the size of the region will
|
|
be 0x3fc00000UL.
