| | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | 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>
| * | Blackfin: BF54x: punt useless "masks" for count/address MMRsMike Frysinger2009-12-151-104/+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>
| * | Blackfin: punt unused MXVR masksMike Frysinger2009-12-152-1957/+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>
| * | Blackfin: punt OTP MMRsMike Frysinger2009-12-156-176/+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>

| | | | | | | | | | | | | | | | | | | | | 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>

| * | Blackfin: convert DMA mutex to an atomic and drop redundant codeMike Frysinger2009-12-152-35/+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.

| * | Blackfin: bf538: add support for extended GPIO banksMichael Hennerich2009-12-158-27/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | Blackfin: clean up isp1362 board resourcesMike Frysinger2009-12-154-140/+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>
| * | Blackfin: calculate on-chip lengths at link time rather than run timeMike Frysinger2009-12-153-39/+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>
| * | Blackfin: improve async bank access checking (for cross-banks & XIP)Bernd Schmidt2009-12-151-15/+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>

For boards that don't actually hook up to this hardware, simply drop the resources altogether.

| * | Blackfin: add some bounds checking to peripheral_requestBarry Song2009-12-151-0/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The next commit will require the use of MODULE_SYMBOL_PREFIX in .tmp_exports-asm.S. Currently it is mixed in with C structure definitions in "asm/module.h". Move the definition of this arch option into Kconfig, so it can be easily accessed by any code. This also lets modpost.c use the same definition. Previously modpost relied on a hardcoded list of architectures in mk_elfconfig.c. A build test for blackfin, one of the two MODULE_SYMBOL_PREFIX archs, showed the generated code was unchanged. vmlinux was identical save for build ids, and an apparently randomized suffix on a single "__key" symbol in the kallsyms data).
