They are interpreted in the imx-image tool, see scripts/imx/README and scripts/imx/imx-image.c. The imx-image tool converts the commands into a dcd table which is understood by the Freescale i.MX ROM Code. The ROM code does not provide a delay command, so what you are looking for does not exist. All the is is a nop command. This is currently not implemented in imx-image, you would have to add it. > > Which commands I can use in the IMXCFG file to create very early > delay, before initialization of DRAM? As said, there is nop. Otherwise there is a 'check' command to poll for setting/clearing bits. See the i.MX reference manual in the "Device Configuration Data (DCD)" section for further information.
