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. - Leonid.
