This option is selected on 32-bit CPUs like Alchemy, which has
36-bit physical address. It will cause a warning about unmet
Just verified - selected Alchemy and DB1000 board and got
# CONFIG_64BIT is not set
CONFIG_64BIT_PHYS_ADDR=y
CONFIG_ARCH_PHYS_ADDR_T_64BIT=y
CONFIG_PHYS_ADDR_T_64BIT=y
???
I also want to say that NetLogic Microsystems web site indicates that
some of Alchemy CPU has only 14 bit DDR/SDRAM address, for exam - Au1550
(http://www.netlogicmicro.com/Products/Alchemy/Au1550.asp) but
arch/mips/configs/db1550_defconfig (and pb1550) choses 64BIT_PHYS_ADDR
too. Seems like something wrong here.
