Subject: [PATCH 638/806] 2711: Add basic 64-bit support
|
2019-07-09 18:32:28 +00:00
|
|
|
|
|
|
|
This commit adds initial support for 64-bit 2711 builds. However,
|
|
|
|
it will only work as much as it does if the Pi4 RAM is limited to
|
|
|
|
1GB - more than that and several things break (SD card, coherent
|
|
|
|
allocations, etc.)
