I hope there is a very strong correlation ;-)

We have 256MB DDR2 RAM and 512MB NAND flash and get the following:

root@dlcpro:~ cat /proc/meminfo

VmallocTotal:     761856 kB
VmallocUsed:       27740 kB
VmallocChunk:     639888 kB

This looks very much the same with either of the kernels, independent of th=
e used toolchain.
For me this looks ok, doesn't it? (Although I must admit I'm not really sur=
e what VmallocTotal tells me and whether it is correct to be so large. Look=
s like RAM + Flash?)

Best regards
Arno
