Re: [U-Boot] [RFC] ARM: U-boot and 2 GiB of ram with get_ram_size only being long

Dear Scott Wood,

In message 1382138723.7979.928.camel@snotra.buserror.net you wrote:

And the one 64-bit environment that we're about to have in U-Boot (armv8) has discontiguous memory, which is another case where get_ram_size() won't work.

get_ram_size() is supposed to be run per memory bank. If you have discontiguous memory, then you probably have several memory banks that can be sized separately?

BTW, shouldn't get_ram_size restore the original data in the final "return (maxsize)" case? I know, patches welcome. :-)

Yes, get_ram_size() is non-destructive (at least in the no-error case; otherwise things like PRAM would not work).

Best regards,
