As space expands, so does the software. Today the kernel with built-in initramfs image is likely to not fit into 8MB limit. It feels safe to increase BOOTMAPSZ to 16MB, since the Linux actually maps 16MB on 6xx PPCs (two BATs, 8MB each).

p.s. The patch for the whole tree is quite big, so let's start with 83xx.
ack,
Great, thanks.
I'm ok with this operation starting in 83xx land, but it may be worth investigating whether it can be made a one-shot directly with WD, just as the CFG_ -> CONFIG_SYS_ switch just happened. dunno. If we don't hear from WD soon, I'll put this in mpc83xx's next branch.
Please don't queue this patch yet. I'll send an updated version soon, that will also define CFG_BOOTM_LEN (so that bootm command will able to gunzip 16MB images).
pp.s. Maybe we could fector out these defines into include/configs/ppc6xx-common.h?
sure, but maybe that can wait until the base domain granularity becomes more accurately visible...
Ok, makes sense.
