The STK1000 uses pullups on the MDIO lines to the PHY, but they are too weak. This causes the PHY layer to detect PHYs on all possible MII addresses. Mask out all but the correct address to prevent this from happening. Signed-off-by: NHaavard Skinnemoen <hskinnemoen@atmel.com>

This adds some STK1002-specific config options covering the jumper settings, so the kernel can automatically be configured to include the relevant devices. One of them replaces the previous internal SW2_DEFAULT setting; SPI config is affected by two of the jumpers; and a fourth one switches between LCD and the second Ethernet connector. (There's more that to be done.) Signed-off-by: NDavid Brownell <dbrownell@users.sourceforge.net> Signed-off-by: NHaavard Skinnemoen <hskinnemoen@atmel.com>

This patch enables CPU frequency scaling for AT32AP devices. This will enable the CPU to scale between the speed of the high speed bus and the master clock and thus save some power. The patch also adds a parent to cpu_clk and a cpu_clk_set_rate to enable changing the CPU clock divider in a sane way. The driver does not check if the given rate is 0, thus resulting in a div by 0. I think this check should be go into the clk_set_rate framework, and not here. Tested on AT32AP7000/ATSTK1000. Hardware documentation can be found in the AT32AP7000 datasheet.

The current generic bug implementation has a call to dump_stack() in case a WARN_ON(whatever) gets hit. Since report_bug(), which calls dump_stack(), gets called from an exception handler we can do better: just pass the pt_regs structure to report_bug() and pass it to show_regs() in case of a warning. This will give more debug informations like register contents, etc... In addition this avoids some pointless lines that dump_stack() emits, since it includes a stack backtrace of the exception handler which is of no interest in case of a warning. E.g. on s390 the following lines are currently always present in a stack backtrace if dump_stack() gets called from report_bug(): [<000000000001517a>] show_trace+0x92/0xe8) [<0000000000015270>] show_stack+0xa0/0xd0 [<00000000000152ce>] dump_stack+0x2e/0x3c [<0000000000195450>] report_bug+0x98/0xf8 [<0000000000016cc8>] illegal_op+0x1fc/0x21c [<00000000000227d6>] sysc_return+0x0/0x10 Acked-by: NJeremy Fitzhardinge <jeremy@goop.org> Acked-by: NHaavard Skinnemoen <hskinnemoen@atmel.com> Cc: Andi Kleen <ak@suse.de> Cc: Kyle McMartin <kyle@parisc-linux.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Paul Mundt <lethal@linux-sh.org> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: NHeiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

The current at32ap7000 platform devices aren't declared as supporting DMA, so that layered drivers can't tell whether they need to manage DMA.

If (start + size) is not cacheline aligned and (start & mask) > (end & mask), the last but one cacheline won't be invalidated as it should. Fix this by rounding `end' down to the nearest cacheline boundary if it gets adjusted due to misalignment. Also flush the write buffer unconditionally -- if the dcache wrote back a line just before we invalidated it, the dirty data may be sitting in the write buffer waiting to corrupt our buffer later.

This patch moves the die notifier handling to common code. Previous various architectures had exactly the same code for it. Note that the new code is compiled unconditionally, this should be understood as an appel to the other architecture maintainer to implement support for it aswell (aka sprinkling a notify_die or two in the proper place) arm had a notifiy_die that did something totally different, I renamed it to arm_notify_die as part of the patch and made it static to the file it's declared and used at. avr32 used to pass slightly less information through this interface and I brought it into line with the other architectures.

With the current strategy of using the bootmem allocator to allocate or reserve framebuffer memory, there's a slight chance that the requested area has been taken by the boot allocator bitmap before we get around to reserving it. By inserting the framebuffer region as a reserved region as early as possible, we improve our chances for success and we make the region visible as a reserved region in dmesg and /proc/iomem without any extra work.

Use struct resource to specify both physical memory regions and reserved regions and push everything into the same framework, including kernel code/data and initrd memory. This allows us to get rid of many special cases in the bootmem initialization and will also make it easier to implement more robust handling of framebuffer memory later.
