Subject: [PATCH] ARM: dts: Remove CMA allocation from Pi 4 dts
|
|
|
|
The 5.5 tree includes a patch to disable the CMA command line
|
|
parameter and replace it with properties from a DT node.
|
|
The upstream Pi 4 .dts, now used downstream with modifications,
|
|
includes the "linux,cma" node, but only reserves 32MB which is
|
|
often not enough.
|
|
|
|
Temporarily remove the "linux,cma" node to reenable the command line
|
|
parameter.
