2010-05-25endian: #define __BYTE_ORDERJoakim Tjernlund
Linux does not define __BYTE_ORDER in its endian header files which makes some header files bend backwards to get at the current endian. Lets #define __BYTE_ORDER in big_endian.h/litte_endian.h to make it easier for header files that are used in user space too. In userspace the convention is that 1. _both_ __LITTLE_ENDIAN and __BIG_ENDIAN are defined, 2. you have to test for e.g. __BYTE_ORDER == __BIG_ENDIAN.

asm-generic/atomic.h has been derived from the mn10300 implementation. Remove the now duplicated mn10300 implementation by including the generic version instead.

2010-05-22Blackfin: optimize strncpy a bitRobin Getz
Add a little strncpy optimization which can easily cut boot time by 20%. When the kernel is booting with initramfs, it builds up the filesystem from a cpio archive by calling strncpy_from_user() via fs/namei.c's do_getname() on every file in the archive (which can be lots) with a length of PATH_MAX (1024). This causes the dest of the strncpy to be padded with many NUL bytes. This optimization mostly causes these NUL bytes to be padded with a call to memset() which is already optimized for filling memory quickly, but the hardware loop helps a little bit as well. Boot time measured with 'loglevel=0' so UART speed doesn't get in the way. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-05-22Blackfin: isram: clean up ITEST_COMMAND macro and improve the selftestsMike Frysinger
The IADDR2DTEST() macro had some duplicated logic with bit 11 and some incorrect comments, so scrub all of that. In order to verify these aren't a problem (and won't be in the future), extend the self tests to operate on as much L1 SRAM as possible. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-05-22Blackfin: move string functions to normal lib/ assemblyRobin Getz
Since 'extern inline' doesn't work correctly in the context of the Linux kernel (too many overriding defines), move the string functions to normal lib/ assembly files (like the existing mem funcs). This avoids the forced inline all over the kernel and allows us to place them constantly in L1. This also avoids some module failures when gcc inserts calls to string functions but the kernel build system doesn't fully consult the library archives.

2010-05-22Blackfin: SIC: cut down on IAR MMR reads a bitMike Frysinger
Tweak the for loops that operate on the SIC IAR system MMRs to avoid re-reading them multiple times in a row. System MMRs are a little slower to access, so avoid the penalty when possible. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-05-22Blackfin: kgdb: pass up the CC register instead of a 0 stubMike Frysinger
While the CC pseudo register can be deduced from the ASTAT register, make sure we set its value correctly instead of always stubbing it out as 0. GDB itself looks at this pseudo register instead of ASTAT, so we have to supply the right value. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-05-22Blackfin: change the BUG opcode to an unused 16-bit opcodeRobin Getz
The current BUG opcode includes the bit that flags the insn as a 32bit opcode, but it wasn't declaring it as 32bits. So pick an unused 16bit. URL: http://blackfin.uclinux.org/gf/tracker/5973 Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-05-22Blackfin: allow NMI watchdog to be used w/RETN as a scratch regGraf Yang
NMIs are not safe to return from because many anomaly workarounds are implemented by disabling interrupts. The NMI obviously violates this assumption. Since the NMI watchdog never returns, we don't have to worry about it clobbering RETN when it is being used as a scratch register with the exception stack.

2010-05-22Blackfin: add support for the DBGA (debug assert) pseudo insnRobin Getz
A few pseudo debug insns exist to make testing of simulators easier. Since these don't actually exist in the hardware, we have to have the exception handler take care of emulating these. This allows sim test cases to be executed unmodified under Linux and thus simplify debugging greatly.
