Package: raspi-firmware
Version: 1.20230405+ds-2

When I set CMA=0 the cma=… argument in cmdline.txt is omitted. This
leads to:

[    0.000000] Memory: 413440K/507904K available (8192K kernel code, 990K rwdata
, 2024K rodata, 1024K init, 252K bss, 28928K reserved, 65536K cma-reserved)


However, when I manually add cma=0 to cmdline.txt I get this instead:

[    0.000000] Memory: 479104K/507904K available (8192K kernel code, 990K rwdata
, 2024K rodata, 1024K init, 252K bss, 28800K reserved, 0K cma-reserved)


This is Debian bullseye/armel (with raspi-firmware from sid)
on an RPi B+ (rev. 1.2).
