[ixp1200] Question on uEngine C compiler

[Shyamal Pandya]

That is because there are a total of 64 sram xfer registers, so each of the 
four contexts of a microengine gets 16 locally addressable xfer regs, out of 
which 8 are read and 8 are for write.

Maybe you should use global addressing for your xfer registers, which will 
give you access to more than 8 read xfer registers. Of course will mean you 
can access fewer local registers.
