2010-05-24m68knommu: improve short help of m68knommu/Kconfig/RAMSIZE for '0' casePhilippe De Muyter
While it is explained in the long help text, meaning of '0' for RAMSIZE is easily overlooked because is not mentioned in the short help text. Add that. Signed-off-by: Philippe De Muyter <phdm@macqel.be> Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2010-05-24m68knommu: remove un-used mcfsmc.hGreg Ungerer
Remove the un-used mcfsmc.h. All ColdFire platforms that use SMC ethernet devices are platform enabled to use the smc91x driver. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2010-05-24m68knommu: add smc91x support for ColdFire NETtel boardsGreg Ungerer
The ColdFire based NETtel boards use the SMC9196 ethernet devices. Switch to using a platform setup for these parts using the smc91x driver. The init code is taken strait out of arch/m68k/include/asm/mcfsmc.h, just cleaned up a bit. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2010-05-24m68knommu: add smc91x support to ColdFire 5249 platformGreg Ungerer
The Freescale M5249EVB board is fitted with an SMC LAN91c11 ethernet device. Add platform support to the M5249EVB setup code to support this. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2010-05-24m68knommu: remove size limit on non-MMU TASK_SIZEGreg Ungerer
The TASK_SIZE define is used in some places as a limit on the size of the virtual address space of a process. On non-MMU systems those addresses used in comparison will be physical addresses, and they could be anywhere in the 32bit physical address space. So for !CONFIG_MMU systems set the TASK_SIZE to the maximum physical address. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

2010-05-23ARM: s5pc100_defconfig: change ARCH_S5PC1XX to ARCH_S5PC100Ben Dooks
Fixup the defconfig post the latest moves, so ARCH_S5PC1XX becomes ARCH_S5PC100 which is sufficient to get the system building. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2010-05-23ARM: S5PC100: Fixup merge problemsBen Dooks
Between problems with Kconfig and merging commits from several different sources, it seems the s5pc100 build's move from plat-s5pc11 has had a few problems. Since I do not have the trees to rebuild this quickly, the easiest thing is to simply fix the errors found once the s5pc100_defconfig actually builds. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

Samsung's Soc S5PC100 has three PL330 DMACs. First is dedicated for Memory->Memory data transfer while the other two meant for data transfer with peripherals.

2010-05-22Blackfin: acvilon: fix timeout usage for I2CWolfram Sang
The timeout value is in jiffies, so it should be using HZ, not a plain number. As '10000' is ambiguous, 1HZ is used as conservative default. Signed-off-by: Wolfram Sang <w.sang@pengutronix.de> Cc: Valentin Yakovenkov <yakovenkov@gmail.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-05-22Blackfin: set ARCH_KMALLOC_MINALIGNFUJITA Tomonori
Architectures that handle DMA-non-coherent memory need to set ARCH_KMALLOC_MINALIGN to make sure that kmalloc'ed buffer is DMA-safe: the buffer doesn't share a cache with the others.

2010-05-22Blackfin: use atomic kmalloc in L1 alloc so it too can be atomicMike Frysinger

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: show the whole accumulator in the pseudo DBG insnRobin Getz

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.
