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
And you didn't get a warning on "select 64BIT_PHYS_ADDR"? Strange, modern
Kconfig should spit out one...
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
arch/mips/configs/db1550_defconfig (and pb1550) choses 64BIT_PHYS_ADDR
too. Seems like something wrong here.
High address bits on Alchemies are used to address PCI/PCMCIA space, not RAM.
