[RFC] MIPS: ath79: make use of the new memory detection code

[RFC] MIPS: ath79: make use of the new memory detection code

[John Crispin]

There is now a generic function for detecting memory size. Use this instead of
the one found in the ath79 support.

Hi Gabor,

I only compile tested this one inside a openwrt tree.

Although this was sent only as an RFC, it is working on top of v2 of the
detect_memory_region patch series.
