2009-12-15Blackfin: gptimers: use unsigned timer/group idsMike Frysinger2-32/+32
Since we always use these ids as unsigned values, and we have some assert code to make sure they don't exceed a limit, avoid signed issues. Reported-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: don't walk VMAs when oopsingRobin Getz1-0/+9
If we're double faulting, then we have to assume the VMAs are not safe as broken pointers here will prevent full trace output for the double fault. Shouldn't be a big problem though as rarely is a double fault caused by code in userspace. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: force BFD target when linking modulesMike Frysinger1-0/+1
This allows us to use any Blackfin toolchain to create kernel modules (such as the FDPIC bfin-linux-uclibc toolchain). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-12-15Blackfin: add an uncompressed vmImage targetMike Frysinger2-2/+7
This is useful for quick tests where networks are faster than compression, and/or the compression code is broken. Reported-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-12-15Blackfin: announce current cpu rev when bootingRobin Getz1-1/+1
User reports rarely include full information, so include this important tidbit up front. It's also good to know at a glance in general. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: unify DMA masksMike Frysinger8-301/+50
Every Blackfin variant has the same DMA bit masks, so avoid duplicating them over and over in each mach header. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: fix typo in isp1760 platform nameMichael Hennerich5-5/+5
The driver changed from "isp1760-hcd" to "isp1760", so update resources to match. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-12-15Blackfin: H8606/ip0x: drop redundant SPI ctl_reg settingsMike Frysinger2-16/+0
No need to set MSTR in .ctl_reg as the Blackfin SPI bus driver does this already for all parts. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: BF54x: punt useless "masks" for count/address MMRsMike Frysinger1-104/+0
There's no point in having mask defines when the entire MMR value is a count or address. i.e. applying a mask of -1 is pointless. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: punt unused MXVR masksMike Frysinger2-1957/+0
There are no MXVR device drivers, and if someday there is, we can put these in a dedicated header rather than polluting the global namespace. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: punt OTP MMRsMike Frysinger6-176/+0
People should not be accessing OTP MMRs directly. They should instead go through the Blackfin ROM helper functions. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: scrub unused watchdog mmr masksMike Frysinger4-109/+0
The watchdog code doesn't need these, and the other parts had these punted, so keep the global namespace clean. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: scrub unused RTC masksMike Frysinger4-147/+0
The RTC driver code doesn't need these, and the other parts had these punted, so keep the global namespace clean. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: unify BF547/8/9 headersMike Frysinger4-5098/+8
No point in duplicating entire lists when we can simply tail into other parts for most of the MMRs. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-12-15Blackfin: rename BF542 host dma definesMike Frysinger1-2/+2
All the other BF54x parts had these defines renamed to avoid collision, but it looks the BF542 was missed somehow. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: punt cache lock documentationMichael Hennerich3-61/+0
The cache lock code was unused and punted, so punt the documentation too. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: coreb: switched to unlocked_ioctlMike Frysinger1-4/+4
We don't need the BKL and now people will stop looking at this. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: convert DMA mutex to an atomic and drop redundant codeMike Frysinger2-35/+13
The DMA channel status field was encoding redundant info wrt the DMA MMR config register, and it was doing an incomplete job of checking all DMA channels (some drivers write directly to the config register). So drop the tristate field in favor of a binary atomic field. This simplifies the code in general, removes the implicit need for sleeping, and forces the suspend code to handle all channels properly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: update bfin_rotary definesMichael Hennerich2-4/+4
The driver was moved during the merge process, so update the defines to match the new location. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: push down asm/ includes and out of bfin-global.hMike Frysinger4-6/+4
Avoid including unnecessary headers all the time as well as circular includes with core requirements. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-12-15Blackfin: bf538: add support for extended GPIO banksMichael Hennerich8-27/+280
The GPIOs on ports C/D/E on the BF538/BF539 do not behave the same way as the other ports on the part and the same way as all other Blackfin parts. The MMRs are programmed slightly different and they cannot be used to generate interrupts or wakeup a sleeping system. Since these guys don't fit into the existing code, create a simple gpiolib driver for them.

2009-12-15Blackfin: add C define of trace_buffer_init()Graf Yang1-0/+2
Have the C API trace funcs match the assembly API trace funcs. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: cpufreq: use a constant latencyMichael Hennerich1-1/+2
PLL_LOCKCNT applies only to the PLL programming sequence which does not apply to core and system clock dividers. Writes to PLL_DIV to change the CSEL/SSEL dividers take effect immediately. There is still overhead in software in writing the new dividers, so just use a value of 50us as this should be good enough.

2009-12-15Blackfin: clean up isp1362 board resourcesMike Frysinger4-140/+2
Drop the CONFIG_USB_ISP1362_BFIN_GPIO_IRQ Kconfig as it never made it into mainline and it was a bad interface into the board resources. For boards that actually used this, replace it with an actual IRQ define. For boards that didn't, simply drop the resources. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: calculate on-chip lengths at link time rather than run timeMike Frysinger3-39/+44
Since the link sizes never change at runtime, push the calculation out to the linker script to save some useless calculation costs. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: improve async bank access checking (for cross-banks & XIP)Bernd Schmidt1-15/+62
The access_ok() function did not accept ranges within the async banks which made it impossible to do XIP in flash. Fixing that also showed that the current bfin_mem_access_type() code did not work with accesses that spanned async banks (like a file system). So split out and fix the async bank checks so that all these scenarios work as expected. Signed-off-by: Bernd Schmidt <bernds_cb1@t-online.de> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: convert DMA code to a proper bitmapMichael Hennerich1-7/+8
Rather than using our own data structures that basically boil down to a bitmap, use the standard bitmap functions. Reported-by: Paul Mundt <lethal@linux-sh.org> Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: clean up bf537-lq035 board resourcesMichael Hennerich4-22/+5
Now that the driver has been updated, convert the board resources to the new i2c framework for managing slaves. For boards that don't actually hook up to this hardware, simply drop the resources altogether.

2009-12-15Blackfin: add some bounds checking to peripheral_requestBarry Song1-0/+2
The requested peripheral is turned into an index into some state arrays, so make sure the calculated index doesn't exceed the index. This occurs when using bogus pin values or the define headers are screwed up. Now we'll notice right away that something needs fixing instead of trying to track down random memory corruption.

2009-12-15Blackfin: use common code for cycle->nanosecond conversionYi Li1-22/+4
No point in redefining things that common code already does for us. Also use CYC2NS_SCALE_FACTOR to better reflect reality and for better precision. Signed-off-by: Yi Li <yi.li@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: unify sched_clock() handling between clock sourcesYi Li1-10/+33
Currently sched_clock() is only defined when using CYCLES as a clock source. Declare sched_clock() in common code and mark it with notrace to prevent invoking sched_clock() recursively (because ftrace uses sched_clock() to record time).

2009-12-15Blackfin: fix gptimer0 clock source compile warningYi Li1-1/+1
Some of the clocksource prototypes were updated, but the gptimer0 func was missed in the process. Not a big issue as the argument is ignored, but we should fix the compile warning anyways. Signed-off-by: Yi Li <yi.li@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
