This allows cpus to be off-lined on 32-bit SMP powermacs. When a cpu is off-lined, it is put into sleep mode with interrupts disabled. It can be on-lined again by asserting its soft-reset pin, which is connected to a GPIO pin. With this I can off-line the second cpu in my dual G4 powermac, which means that I can then suspend the machine (the suspend/resume code refuses to suspend if more than one cpu is online, and making it cope with multiple cpus is surprisingly messy).

Sanitized and fixed floppy dependencies: split the messy dependencies for BLK_DEV_FD by introducing a new symbol (ARCH_MAY_HAVE_PC_FDC), making BLK_DEV_FD depend on that one and taking declarations of ARCH_MAY_HAVE_PC_FDC to arch/*/Kconfig. While we are at it, fixed several obvious cases when BLK_DEV_FD should have been excluded (architectures lacking asm/floppy.h are *not* going to have floppy.c compile, let alone work). If you can come up with better name for that ("this architecture might have working PC-compatible floppy disk controller"), you are more than welcome - just s/ARCH_MAY_HAVE_PC_FDC/your_prefered_name/g in the patch below...

Adds support for the two PCI busses on MPC83xx and the MPC834x SYS/PIBS reference board. The code initializes PCI inbound/outbound windows, allocates and registers PCI memory/io space.

Create a new top-level menu named "Networking" thus moving net related options and protocol selection way from the drivers menu and up on the top-level where they belong. To implement this all architectures has to source "net/Kconfig" before drivers/*/Kconfig in their Kconfig file. This change has been implemented for all architectures. Device drivers for ordinary NIC's are still to be found in the Device Drivers section, but Bluetooth, IrDA and ax25 are located with their corresponding menu entries under the new networking menu item.

This patch adds the Freescale MPC86xADS board support. The supported devices are SMC UART and 10Mbit ethernet on SCC1. The manual for the board says that it "is compatible with the MPC8xxFADS for software point of view". That's why this patch extends FADS instead of introducing a new platform. FEC is not supported as the "combined FCC/FEC ethernet driver" driver by Pantelis Antoniou should replace the current FEC driver.

I have tweaked this patch slightly to handle an empty list of pages to relocate passed to relocate_new_kernel. And I have added ppc_md.machine_crash_shutdown. To keep up with the changes in the generic kexec infrastructure. From: Albert Herranz <albert_herranz@yahoo.es> The following patch adds support for kexec on the ppc32 platform. Non-OpenFirmware based platforms are likely to work directly without additional changes on the kernel side. The kexec-tools userland package may need to be slightly updated, though. For OpenFirmware based machines, additional work is still needed on the kernel side before kexec support is ready. Benjamin Herrenschmidt is kindly working on that part. In order for a ppc platform to use the kexec kernel services it must implement some ppc_md hooks. Otherwise, kexec will be explicitly disabled, as suggested by benh. There are 3+1 new ppc_md hooks that a platform supporting kexec may implement. Two of them are mandatory for kexec to work. See include/asm-ppc/machdep.h for details. - machine_kexec_prepare(image) This function is called to make any arrangements to the image before it is loaded. This hook _MUST_ be provided by a platform in order to activate kexec support for that platform. Otherwise, the platform is considered to not support kexec and the kexec_load system call will fail (that makes all existing platforms by default non-kexec'able). - machine_kexec_cleanup(image) This function is called to make any cleanups on image after the loaded image data it is freed. This hook is optional. A platform may or may not provide this hook. - machine_kexec(image) This function is called to perform the _actual_ kexec. This hook _MUST_ be provided by a platform in order to activate kexec support for that platform. If a platform provides machine_kexec_prepare but forgets to provide machine_kexec, a kexec will fall back to a reboot. A ready-to-use machine_kexec_simple() generic function is provided to, hopefully, simplify kexec adoption for embedded platforms. A platform may call this function from its specific machine_kexec hook, like this: void myplatform_kexec(struct kimage *image) { machine_kexec_simple(image); } - machine_shutdown() This function is called to perform any machine specific shutdowns, not already done by drivers. This hook is optional. A platform may or may not provide this hook. An example (trimmed) platform specific module for a platform supporting kexec through the existing machine_kexec_simple follows: /* ... */ #ifdef CONFIG_KEXEC int myplatform_kexec_prepare(struct kimage *image) { /* here, we can place additional preparations */ return 0; /* yes, we support kexec */ } void myplatform_kexec(struct kimage *image) { machine_kexec_simple(image); } #endif /* CONFIG_KEXEC */ /* ... */ void __init platform_init(unsigned long r3, unsigned long r4, unsigned long r5, unsigned long r6, unsigned long r7) { /* ... */ #ifdef CONFIG_KEXEC ppc_md.machine_kexec_prepare = myplatform_kexec_prepare; ppc_md.machine_kexec = myplatform_kexec; #endif /* CONFIG_KEXEC */ /* ... */ } The kexec ppc kernel support has been heavily tested on the GameCube Linux port, and, as reported in the fastboot mailing list, it has been tested too on a Moto 82xx ppc by Rick Richardson.

For all architectures, this just means that you'll see a "Memory Model" choice in your architecture menu. For those that implement DISCONTIGMEM, you may eventually want to make your ARCH_DISCONTIGMEM_ENABLE a "def_bool y" and make your users select DISCONTIGMEM right out of the new choice menu. The only disadvantage might be if you have some specific things that you need in your help option to explain something about DISCONTIGMEM.

This patch adds on-chip PCI bridge support for the PQ2 family. The incomplete existent code is updated with interrupt handling stuff and board-specific bits for 8272ADS and PQ2FADS; the related files were renamed (from m8260_pci to m82xx_pci) to be of more generic fashion. This is tested with 8266ADS and 8272ADS, should work on PQ2FADS as well.

A bunch of drivers use ISA DMA helpers or their equivalents for platforms that have ISA with different DMA controller (a lot of ARM boxen). Currently there is no way to put such dependency in Kconfig - CONFIG_ISA is not it (e.g. it is not set on platforms that have no ISA slots, but have on-board devices that pretend to be ISA ones). New symbol added - ISA_DMA_API. Set when we have functional enable_dma()/set_dma_mode()/etc. set of helpers. Next patches in the series will add missing dependencies for drivers that need them. I'm very carefully staying the hell out of the recurring flamefest on what exactly CONFIG_ISA would mean in ideal world - added symbol has a well-defined meaning and for now I really want to treat it as completely independent from the mess around CONFIG_ISA.

To add support for 36-bit physical addressing on e500 the following changes have been made. The changes are generalized to support any physical address size larger than 32-bits: * Allow FSL Book-E parts to use a 64-bit PTE, it is 44-bits of pfn, 20-bits of flags. * Introduced new CPU feature (CPU_FTR_BIG_PHYS) to allow runtime handling of updating hardware register (SPRN_MAS7) which holds the upper 32-bits of physical address that will be written into the TLB. This is useful since not all e500 cores support 36-bit physical addressing. * Currently have a pass through implementation of fixup_bigphys_addr * Moved _PAGE_DIRTY in the 64-bit PTE case to free room for three additional storage attributes that may exist in future FSL Book-E cores and updated fault handler to copy these bits into the hardware TLBs.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
