* | powerpc/4xx: Add pcix type 1 transactionsStef van Os2010-01-291-1/+2
| | | | | | | | | | | | | | | | | | | | | | Some of the newer 4xx pci cores need an explicit bit set to send type 1 transactions instead of just comparing the bus numbers. This patch enables type 1 transations for pcix nodes, thus enabling devices behind PCI bridges.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mkuboot.sh provides a basic wrapper for the 'mkimage' utility. Using mkuboot.sh provides clearer error reporting and allows a toolchain to use its own 'mkimage' executable specified by ${CROSS_COMPILE}mkimage. Additionally, this brings PowerPC in line with other architectures which already call mkimage via mkuboot.sh.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We noticed that recent kernels didn't boot on our 1GHz Canyonlands 460EX boards anymore. As it seems, patch 8d165db1 [powerpc: Improve decrementer accuracy] introduced this problem. The routine div_sc() overflows with shift = 32 resulting in this incorrect setup: time_init: decrementer frequency = 1000.000012 MHz time_init: processor frequency = 1000.000012 MHz clocksource: timebase mult[400000] shift[22] registered clockevent: decrementer mult[33] shift[32] cpu[0] This patch now introduces a local div_dc64() version of this function so that this overflow doesn't happen anymore.

It attempts to add an include of autoconf.h but used the wrong path for it. It also adds -D__KERNEL__ to our boot wrapper, both things that we pretty much didn't do on purpose so far. We want our boot wrapper to remain independent enough of the kernel for various reasons, one of them being that you can "wrap" an existing kernel at distro install time which allows to ship one kernel image and a set of boot wrappers for different platforms, the wrappers don't have to be built out of the same kernel build tree. It's also incorrect to do what the patch does in our boot environment since we may not have a proper alignment exception handler which means we may not be able to fixup the few cases where an unaligned access will need SW emulation (depends on the core variant, could be when crossing page or segment boundaries for example). This patch fixes it by putting the old code back in and using the new "fancy" variant only when CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is set, which happens not to be set on powerpc since we don't include autoconf.h. It also reverts the changes to our boot wrapper Makefile. This means that x86 should, afaik, keep the optimisations since its boot wrapper does include autoconf.h and define __KERNEL__ (though I doubt they make that much different outside of slow embedded processors).

* | | zlib: optimize inffast when copying direct from outputJoakim Tjernlund2010-01-111-1/+3
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | JFFS2 uses lesser compression ratio and inflate always ends up in "copy direct from output" case. This patch tries to optimize the direct copy procedure. Uses get_unaligned() but only in one place. The copy loop just above this one can also use this optimization, but I havn't done so as I have not tested if it is a win there too. On my MPC8321 this is about 17% faster on my JFFS2 root FS than the original.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cardbus code creates PCI devices without ever going through the necessary fixup bits and pieces that normal PCI devices go through. There's in fact a commented out call to pcibios_fixup_bus() in there, it's commented because ... it doesn't work. I could make pcibios_fixup_bus() do the right thing on powerpc easily but I felt it cleaner instead to provide a specific hook pci_fixup_cardbus for which a weak empty implementation is provided by the PCI core. This fixes cardbus on powerbooks and probably all other PowerPC platforms which was broken completely for ever on some platforms and since 2.6.31 on others such as PowerBooks when we made the DMA ops mandatory (since those are setup by the fixups).

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It appears that we wrongly calculate dev_base for type1 config cycles. The thing is: we shouldn't subtract hose->first_busno because PCI core sets PCI primary, secondary and subordinate bus numbers, and PCIe controller actually takes the registers into account. So we should use just bus->number. Also, according to MPC8315 reference manual, primary bus number should always remain 0. We have PPC_INDIRECT_TYPE_SURPRESS_PRIMARY_BUS quirk in indirect_pci.c, but since 83xx is somewhat special, it doesn't use indirect_pci.c routines, so we have to implement the quirk specifically for 83xx PCIe controllers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The retry logic in ug_putc() is broken. If the TX fifo is not ready and the counter runs out it will have a value of -1 and no transfer should be attempted. Also, a counter with a value of 0 means that the TX fifo got ready in the last try and the transfer should be attempted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 57b150cce8e004ddd36330490a68bfb59b7271e9, desc->affinity of an irq is changed after calling desc->chip->set_affinity. Therefore we need to fix the irq_choose_cpu() not to depend on the desc->affinity for new mask.
