2009-01-07Blackfin arch: Faster C implementation of no-MPU CPLB handlerBernd Schmidt
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: Mike Frysinger <vapier.adi@gmail.com> Signed-off-by: Bernd Schmidt <bernds_cb1@t-online.de> Signed-off-by: Bryan Wu <cooloney@kernel.org>
2009-01-07Blackfin arch: panic when running on a chip rev below what we are compiled forRobin Getz
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).

2009-01-07Blackfin arch: fix bugs in linker script when using upstream binutilsBernd Schmidt
Fix a few problems I discovered when building a kernel with upstream CVS binutils. We have to add the NOTES macro to our linker script, since a kernel built with --build-id is otherwise unable to boot. Last time NOTES was added, it broke things, but the definition of the macro has changed not to rely on parts of the linker script that aren't present on Blackfin. I also noticed that _l2_lma_start does not point into the kernel image, but rather somewhere in L1/L2 space, which seems unintended. Also, when the L2 section was added to the linker script, the part following it which computes then length of the init section was not updated.
