Linux kernel 4.19.35 


Currently, I am flashing kernel 4.19.35 and my custom device tree in the imx8qxp custom board via fastboot.

UUU command:

CFG: FB: -vid 0x1fc9 -pid 0x012f
FB: ucmd setenv fastboot_buffer ${loadaddr}
FB: download -f Image
FB: ucmd setenv fastboot_buffer ${fdt_addr}
FB: download -f fsl-imx8qxp-mek.dtb
FB: download -f unimog-imx8qxp-sthu.dtb
FB: acmd booti ${loadaddr} - ${fdt_addr}
FB: done



SCFW only uses gpt4 for M4.


imx8qx_bl31_setup.c handles the gpt0 . Only change made in ATF firmware was changing from uart0 to uart1, as the custom boards handles.

As the bl31 firmware handles the gpt0 for linux kernel, while booting my device tree and Image, why is gpt0 not owned by A35 kernel?
