So IIUC that is 49472 bytes more text & data? ~48KB.
I think what really matters is the 2MB limit on compressed
kernel size, which I guess can be pushed a bit by
compressing the kernel with something violent like ZST but
ultimately what EP93xx might want to do is to do what
the other SoCs are doing for accommodating Android: move
out as many drivers as possible to be modules and
not compiled into the static kernel. Do we have candidates
for that? Are people normally using modules on EP93xx?
I am modernizing XScale IXP4xx and it doesn't suffer
from this as much: even the really ancient NSLU2 has
32MB of RAM.
Yours,
Linus Walleij
