| * Blackfin: add preliminary support for STACKTRACEMike Frysinger2009-06-133-0/+57
| | | | | | | | Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: move custom sections into sections.hMike Frysinger2009-06-132-10/+12
| | | | | | | | | | | | | | The Blackfin arch has a bunch of custom section markings for its on-chip regions, but they aren't declared in the right header. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: punt unused/wrong mutex-dec.hMike Frysinger2009-06-131-112/+0
| | | | | | | | | | | | | | Looks like the mutex-dec.h header file was incorrectly copied into the Blackfin asm path. Nothing uses it, so punt it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: add support for irqflagsMike Frysinger2009-06-134-264/+77
| | | | | | | | | | | | | | | | This converts the irq handling in the Blackfin arch from the old irq.h / system.h method to the new irqflags.h. A stepping stone on the way to other tracing functionality. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: add support for bzip2/lzma compressed kernel imagesMike Frysinger2009-06-134-10/+34
| | | | | | | | | | | | | | Since U-Boot can support these compression types, add appropriate targets to the Blackfin boot files. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: convert Kconfig style to def_boolMike Frysinger2009-06-131-24/+12
| | | | | | | | | | | | Makes the file easier to read when there isn't so much clutter. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: bf548-ezkit: update smsc911x resourcesMike Frysinger2009-06-131-0/+13
| | | | | | | | | | | | | | The older smsc911x driver made platform data optional, but the newer one always requires it, so add proper settings to the BF548-EZKIT. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | | | | | | | | | | | | The SPI flash on the BF518F-EZBRD board is actually hooked up to CS2, not CS1, so make sure the resources are correct.

| * Blackfin: define SPI IRQ in board resourcesYi Li2009-06-1318-3/+113
| | | | | | | | | | | | | | | | The Blackfin SPI driver can be driven by an IRQ now, so declare it in the board resources. Signed-off-by: Yi Li <yi.li@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: do not configure the UART early if on wrong processorRobin Getz2009-06-131-2/+6
| | | | | | | | | | | | | | | | | | Before we configure the early UART, check to make sure we are running on the expected processor - otherwise, we cause problems by configuring pins that don't exist (and causing an infinite loop of faults).

| * Blackfin: fix deadlock in SMP IPI handlerSonic Zhang2009-06-131-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | When a low priority interrupt (like ethernet) is triggered between 2 high priority IPI messages, a deadlock in disable_irq() is hit by the second IPI handler. This is because the second IPI message is queued within the first IPI handler, but the handler doesn't process all messages, and new ones are inserted rather than appended. So now we process all the pending messages, and append new ones to the pending list.

| * Blackfin: fix flag storage for irq funcsMike Frysinger2009-06-132-9/+10
| | | | | | | | | | | | | | The IRQ functions take an "unsigned long" flags variable, not any other type, so fix the places where we use "int" or "long". Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: push down exception oops checkingMike Frysinger2009-06-131-45/+43
| | | | | | | | | | | | | | | | | | Rather than maintain a duplicate list of valid exceptions we can take in the kernel both in the first if() check and the switch() check, delay the oops check to after the switch(). All valid exceptions will have returned by this point leaving only the invalid ones. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: fix trap_c() exit pathsMike Frysinger2009-06-131-5/+5
| | | | | | | | | | | | | | | | The trap_c() code pushes the hardware trace status onto the stack, but doesn't always restore it when returning from some trap code paths. So unify the exit code paths to all head to the end of the function. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: add blackfin_invalidate_entire_icache for SMP systemsSonic Zhang2009-06-136-4/+37
| | | | | | | | | | | | | | | | The KGDB code uses this when switching processors to make sure the icache is in a valid state. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: include the cpu compiled version in /proc/cpuinfoRobin Getz2009-06-131-2/+11
| | | | | | | | | | | | | | | | Since the compiled-for cpu revision can be significant, include it in the cpuinfo output along side the cpu revision we're currently running on. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| * Blackfin: export ip_compute_csum/csum_partial_copy_from_user symbolsMike Frysinger2009-06-131-0/+2
| | | | | | | | | | | | | | All other arches do this, and some places like the net/scsi code will fail as modules without them. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: only handle CPLB protection violations when MPU is enabledRobin Getz2009-06-132-55/+10
| | | | | | | | | | | | | | | | | | | | | | We don't need to handle CPLB protection violations unless we are running with the MPU on. Fix the entry code to call common trap_c, and remove the code which is never run. This allows the traps test suite to run on older boards with the MPU disabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current asm-generic/page.h only contains the get_order function, and asm-generic/uaccess.h only implements unaligned accesses. This renames the file to getorder.h and uaccess-unaligned.h to make room for new page.h and uaccess.h file that will be usable by all simple (e.g. nommu) architectures.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing asm-generic/atomic.h only defines the atomic_long type. This renames it to atomic-long.h so we have a place to add a truly generic atomic.h that can be used on all non-SMP systems.

| * | asm-generic: introduce asm/bitsperlong.hArnd Bergmann2009-06-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This provides a reliable way for asm-generic/types.h and other files to find out if it is running on a 32 or 64 bit platform. We cannot use CONFIG_64BIT for this in headers that are included from user space because CONFIG symbols are not available there. We also cannot do it inside of asm/types.h because some headers need the word size but cannot include types.h. The solution is to introduce a new header <asm/bitsperlong.h> that defines both __BITS_PER_LONG for user space and BITS_PER_LONG for usage in the kernel. The asm-generic version falls back to 32 bit unless the architecture overrides it, which I did for all 64 bit platforms.

| |/ | | | | | | | | | | | | | | | | | | The existing asm-generic versions are incomplete and included by some architectures. New architectures should be able to use a generic version, so rename the existing files and change all users, which lets us add the new files.

* | Blackfin: fix sparseirq/kstat_irqs falloutMike Frysinger2009-06-121-0/+2
| | | | | | | | | | | | | | | | | | The sparseirq changes (d7e51e66) played poorly with the Blackfin irqchip implementation as we're still using the old hardirq method. Our bad irq structure had a NULL kstat_irqs field so when all the common code tries to increment this field, everything goes big bada boom. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* | Blackfin: fix unused warnings after nommu updateMike Frysinger2009-06-121-1/+0
| | | | | | | | | | | | | | The massive nommu update (8feae131) left the local variable "vml" unused, so punt it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* | Blackfin: export the last exception cause via debugfsRobin Getz2009-06-121-0/+10
| | | | | | | | | | | | | | | | | | | | We have some test code that runs in userspace that exercises the exception handling of the Blackfin pretty thoroughly. Part of the validation process is checking the exact exception triggered, so export the last one seen to userspace via debugfs when debugging is enabled for the test code to check.

| | | | | | | | | | | | | | | | | | The kgdb_ebin2mem() was decrementing the count variable to do parsing, but then later still tries to use it based on its original meaning. So leave it untouched and use a different variable to walk the memory. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* | Blackfin: kgdb: fix up error return valuesMike Frysinger2009-06-121-25/+30

* | Blackfin: push access_ok() L1 attribute downMike Frysinger2009-06-122-4/+3
| | | | | | | | | | | | | | | | | | There is no need for the L1 attribute to be on the prototype of the access_ok() function as all consumers of the function do not care where it lives -- they'll always use pcrel calls to get to it. This prevents pointless recompiles of most of the system when this config option changes. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* | Blackfin: punt duplicated search_exception_table() prototypeMike Frysinger2009-06-121-3/+0
| | | | | | | | | | | | | | The common code already has a prototype for this function and we don't use it anywhere in the Blackfin code, so punt it from the Blackfin headers. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* | Blackfin: add missing access_ok() checks to user functionsRobin Getz2009-06-121-5/+20
| | | | | | | | | | | | | | | | The core string/clear user functions weren't checking the user pointers which caused kernel crashes with some bad programs and tests (like LTP). Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* | Blackfin: convert early_printk EVT init to a loopMike Frysinger2009-06-121-13/+3
| | | | | | | | | | | | | | | | | | The EVT registers are all contiguous in the memory map, so using a loop to initialize them all rather than hardcoding the list results in much better generated code (a hardware loop rather than a whole bunch of individual loads).

* | Blackfin: document the lsl variants of the L1 allocatorMike Frysinger2009-06-121-0/+4

* | Blackfin: rename Blackfin relocs according to the toolchainMike Frysinger2009-06-122-53/+53
| | | | | | | | | | | | | | | | The latest Blackfin toolchain has fixed its relocation scheme to match other ports: always use R_BFIN_ prefix and capitalize everything. This brings the kernel in line with those fixes. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* | Blackfin: check SIC defines rather than variant namesMike Frysinger2009-06-121-9/+8
| | | | | | | | | | | | | | | | Rather than having to maintain a hard coded list of Blackfin variants, use the SIC defines themselves. This fixes build problems on BF51x/BF538 under some configurations as they were missing from one of the lists. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* | Blackfin: override default uClinux MTD addr/sizeMike Frysinger2009-06-121-4/+7
| | | | | | | | | | | | | | | | | | | | Due to a processor anomaly (05000263 to be exact), most Blackfin parts cannot keep the embedded filesystem image directly after the kernel in RAM. Instead, the filesystem needs to be relocated to the end of memory. As such, we need to tweak the map addr/size during boot for Blackfin systems. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | | | | | | | | | | Commit 6b3087c6 (which introduced Blackfin SMP) broke command line passing when the DEBUG_DOUBLEFAULT config option was enabled. Switch the code to using a scratch register and not R7 which holds the command line. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
