Ar71xx calibration data

Reported by: lwang998@… Owned by: developers
Priority: normal Milestone: Barrier Breaker 14.07
Component: kernel Version: Trunk
Keywords: Cc:


Hi developer,

I want know why does the calibration data begin at 0x1fff0000(art = (u8 *) KSEG1ADDR(0x1fff0000)),but in the reboot,calibration data begin at 0xbf7f0000 in Atheros AP96 reference board.what does the relate between 0x1fff0000 and 0xbf7f000?

Otherwise,I can't read calibration data if I use ioremap() function to instead of KSEG1ADDR() macro (KSEG1ADDR(0x1fff0000) ==> ioremap(0xbf7f000)).Can u tell me the reason?

0xbf7f0000 is a virtual address, not a physical one, so you can't use ioremap on it. the correct physical address is 0x1f7f0000.
