This is a mixture ofcMichael McTernan's patch and the existing cplb-mpu code. We ditch the old cplb-nompu implementation, which is a good example of why a good algorithm in a HLL is preferrable to a bad algorithm written in assembly. Rather than try to construct a table of all posible CPLBs and search it, we just create a (smaller) table of memory regions and their attributes. Some of the data structures are now unified for both the mpu and nompu cases. A lot of needless complexity in cplbinit.c is removed. Further optimizations: * compile cplbmgr.c with a lot of -ffixed-reg options, and omit saving these registers on the stack when entering a CPLB exception. * lose cli/nop/nop/sti sequences for some workarounds - these don't * make sense in an exception context Additional code unification should be possible after this. [Mike Frysinger <vapier.adi@gmail.com>: - convert CPP if statements to C if statements - remove redundant statements - use a do...while loop rather than a for loop to get slightly better optimization and to avoid gcc "may be used uninitialized" warnings ... we know that the [id]cplb_nr_bounds variables will never be 0, so this is OK - the no-mpu code was the last user of MAX_MEM_SIZE and with that rewritten, we can punt it - add some BUG_ON() checks to make sure we dont overflow the small cplb_bounds array - add i/d cplb entries for the bootrom because there is functions/data in there we want to access - we do not need a NULL trailing entry as any time we access the bounds arrays, we use the nr_bounds variable ] Signed-off-by:Michael McTernan <mmcternan@airvana.com> Signed-off-by:

If we are running on a chip revision below what we are compiled for, there will be missing anomaly workarounds, and a panic is inevitable. Do is sooner, rather than later, so people don't look for bugs that already have workarounds (that they turned off). Signed-off-by:

Michael says that some bugs are crashes in tcp_v4_send_reset. There's a missing clobber of "CC" in our checksum assembly statement; fixing this makes the generated code look much saner. Signed-off-by:

- unify all dma in/out functions (takes ~35 lines of code now) - unify dma_memcpy with dma in/out functions (1 place that touches MDMA0 registers) - add support for 32bit transfers - cleanup dma_memcpy code to be much more readable - irqs are disabled only while programming MDMA registers rather than the entire transaction Signed-off-by:
