Subject: arm64: dts: tqmls1046a: Move BMAN/QMAN buffers to DRAM1 area
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b49f2dece02501c0684de70b7e00d1f7742aac88;p=thirdparty%2Fkernel%2Flinux.git

arm64: dts: tqmls1046a: Move BMAN/QMAN buffers to DRAM1 area

DRAM1 is only 2GiB in size (0x00_8000_0000 - 0x01_0000_0000) which is
already used by Linux kernel, etc. Move the allocation area of BMAN and
QMAN to DRAM1 region. This frees the complete DRAM2 area for e.g. CMA.
