Is this correct? reg = <0x11a80 0x20 0x87fc 2>; I also understand, that latest development kernel contains some significant changes in SMC UART code, especially in muram code, is this correct? So does this reg value reflect this change? >> Can someone, also, explain, how "fsl, cpm-command" field works, >It's the device-specific portion of the value that gets written to the CPM >command register (page, sub-block, and mcc channel). Is it possible to get a quick list of all values for all 8260 soc devices somewhere ? Or do I have to dig specific Freescale reference for it? I am particularly interested in SMC2 and FCC1,2 and 3 ?
