The second reg resource depends on where your firmware set up the SMC pram
regs. With U-boot, it's usually zero.
Note that as of 2.6.26-rc1, this is set up dynamically instead, and the
second resource should be .
Is this correct?
reg = <0x11a80 0x20 0x87fc 2>;
Yes.
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?
Yes, those are the changes I was referring to.
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?
See table 13-6 (CP Command Register Field Descriptions) in the 8260 manual.
I am particularly interested in SMC2 and FCC1,2 and 3 ?
SMC2: 0x21200000
FCC1: 0x12000000 (ATM 0x11c00280)
FCC2: 0x16200000 (ATM 0x15c00280)
FCC3: 0x1a400000
For FCCs, add 0x300 for Ethernet, 0x3c0 for transparent.
