-Subject: [PATCH] configs: arm64: Add support for RPi4 with more than 1G of
- memory
-
-Add the required memory regions to support 2G, 4G and 8G RAM variants
-of the Raspberry Pi 4. Tested on all the bigger variants, not on 1G, as I don't
-have one on hand and it's not available anymore.
-
-Also moved the memory used by Jailhouse for the hypervisor and cells from
-0x30000000 to 0x20000000 to avoid conflict with GPU memory. That is fine for
-gpu_mem setting of up to 256. The memory is supposed to be reserved using
-reserved-memory node in the device tree. To support variants with >2G RAM,
-another region for PCI MMIO space has to be also reserved.
