In the file "Implement Low-Power Audio on i.MX8M" (AN12195.pdf) in subsection 5.1.4. "Apply low-power patch and build bl31.bin"
I'm not sure about "git apply . /0001-Patch-for-low-power-application.patch" command where to run it
I have downloaded the AN12195SW file from the website and found "0001-Patch-for-low-power-application.patch" in LPAudio_Code/arm-trusted-firmware-patch.
I tried to put it in imx-atf and run "git apply . /0001-Patch-for-low-power-application.patch", and I get the following error
================================
imx-atf$ git apply ./0001-Patch-for-low-power-application.patch
./0001-Patch-for-low-power-application.patch:83: space before tab in indent.
}
warning: 1 line adds whitespace errors.
================================
Incidentally, where should I run "make PLAT=imx8mq bl31"
