| | | | | | | | | | | | Replace multiple nearly-identical copies of code to walk through an FDT node's interrupts=<...> property creating resource list entries with a single common implementation. This change makes ofw_bus_intr_to_rl() the one true copy of that code and removes the copies of it from other places. This also adds handling of the interrupts-extended property.

| | | | | | | | | | | | | | | | | | | | | | | | Set ofwbus and simplebus to attach during BUS_PASS_BUS. Define names that drivers can use to adjust their position relative to other drivers within a BUS_PASS Adjust ofwbus and simplebus to attach at BUS_PASS_ORDER_MIDDLE, so that a platform can attach some other bus first if necessary. Set the pl310 L2 cache driver to attach during the middle of BUS_PASS_CPU. Attach arm generic interrupt and timer drivers in the middle of BUS_PASS_INTERRUPT and BUS_PASS_TIMER, respectively. Add an arm option, ARM_DEVICE_MULTIPASS, used to opt-in to multi-pass device attachment on arm platforms. If this is defined, nexus attaches early in BUS_PASS_BUS, and other busses and devices attach later, in the pass number they are set up for. Without it defined, nexus attaches in BUS_PASS_DEFAULT and thus so does everything else, which is status quo. Notes: svn path=/stable/10/; revision=270075

Make it possible to access the ocotp registers before the ocotp device is attached, by establishing a temporary mapping of the registers when necessary. It turns out Freescale cleverly made the ocotp device compatible across several different families of SoCs, so move it to the freescale directory and prefix everything with fsl rather than imx6. Convert the imx6 sdhci "R1B fix" from a busy-loop in the interrupt handler to a callout. Increase the wait time for acquiring the SD bus from 10 to 250ms. If no compatible cards were found after probing the SD bus, say so. Add timeout logic to sdhci, separate from the timeouts done by the hardware. After a timeout, reset the controller using SDHCI_RESET_CMD|SDHCI_RESET_DATA rather than SDHCI_RESET_ALL; the latter turns off clocks and power, removing any possibility of recovering from the error. Add a helper routine to depth-search the device tree for a node with a matching 'compatible' property. Notes: svn path=/stable/10/; revision=266200

Move Open Firmware device root on PowerPC, ARM, and MIPS systems to a sub-node of nexus (ofwbus) rather than direct attach under nexus. This fixes FDT on x86 and will make coexistence with ACPI on ARM systems easier. SPARC is unchanged. Add the missing ')' at end of sentence. Reword it to use a more common idiom. Pass the kernel physical address to initarm through the boot param struct. Make functions only used in vfp.c static, and remove vfp_enable. Fix __syscall on armeb EABI. As it returns a 64-bit value it needs to place 32-bit data in r1, not r0. 64-bit data is already packed correctly. Use abp_physaddr for the physical address over KERNPHYSADDR. This helps us remove the need to load the kernel at a fixed address. Remove references to PHYSADDR where it's used only in debugging output. Dynamically generate the page table. This will allow us to detect the physical address we are loaded at to change the mapping. Notes: svn path=/stable/10/; revision=266160

| | | | | | | | | | | | | | | | | | | | | | | | | | | | r261405 Open Firmware interrupt specifiers can consist of arbitrary-length byte strings and include arbitrary information (IRQ line/domain/sense). When the ofw_bus_map_intr() API was introduced, it assumed that, as on most systems, these were either 1 cell, containing an interrupt line, or 2, containing a line number plus a sense code. It turns out a non-negligible number of ARM systems use 3 (or even 4!) cells for interrupts, so make this more general. Provide a simpler and more standards-compliant simplebus implementation to get the Routerboard 800 up and running with the vendor device tree. This does not implement some BERI-specific features (which hopefully won't be necessary soon), so move the old code to mips/beri, with a higher attach priority when built, until MIPS interrupt domain support is rearranged. Allow nesting of simplebuses. Add a set of helpers (ofw_bus_get_status() and ofw_bus_status_okay()) to process "status" properties of OF nodes. Fix one remnant endian flaw in nexus.

Correct license statements to reflect the fact that these files were all derived from sys/arm/mv/bus_space.c. In pmap_unmapdev(), remember the size, and use that as an argument to kva_free(), or we'd end up always passing it a size of 0 In pmap_mapdev(), first check whether a static mapping exists, Convert TI static device mapping to use the new arm_devmap_add_entry(), Use the common armv6 fdt_bus_tag defintion for tegra instead of a local copy. Eliminate use of fdt_immr_addr(), it's not needed for tegra Convert lpc from using fdt_immr style to arm_devmap_add_entry() to make static device mappings. Retire machine/fdt.h as a header used by MI code, as its function is now obsolete. This involves the following pieces: - Remove it entirely on PowerPC, where it is not used by MD code either - Remove all references to machine/fdt.h in non-architecture-specific code (aside from uart_cpu_fdt.c, shared by ARM and MIPS, and so is somewhat non-arch-specific). - Fix code relying on header pollution from machine/fdt.h includes - Legacy fdtbus.c (still used on x86 FDT systems) now passes resource requests to its parent (nexus). This allows x86 FDT devices to allocate both memory and IO requests and removes the last notionally MI use of fdtbus_bs_tag. - On those architectures that retain a machine/fdt.h, unused bits like FDT_MAP_IRQ and FDT_INTR_MAX have been removed. Add #include <machine/fdt.h> to a few files that used to get it via pollution Enable the mv cesa security/crypto device by providing the required property in the dts source, and adding the right devices to the kernel config. Remove dev/fdt/fdt_pci.c, which was code specific to Marvell ARM SoCs, related to setting up static device mappings. Since it was only used by arm/mv/mv_pci.c, it's now just static functions within that file, plus one public function that gets called only from arm/mv/mv_machdep.c. Switch RPi to using arm_devmap_add_entry() to set up static device mapping. Allow 'no static device mappings' to potentially work. Don't try to find a static mapping before calling pmap_mapdev(), that logic is now part of pmap_mapdev() and doesn't need to be duplicated here. Switch a10 to using arm_devmap_add_entry() to set up static device mapping. Notes: svn path=/stable/10/; revision=266084

Remove unnecessary double-setting of the thread's onfault state in copyinstr(). Open Firmware mandates that certain cross-references, in particular those in /chosen, be ihandles. The ePAPR spec makes those cross-reference phandles, since FDT has no concept of ihandles. Have the OF FDT CI module interpret queries about ihandles as cross-reference phandles. Real OF systems have an ihandle under /chosen/stdout, not a phandle. Use the right type. Rearchitect platform memory map parsing to make it less Open Firmware-centric. Remove fdtbus_bs_tag definition, which is now obsolete. The remainder of this file is also slated for future demolition. Return the correct IEEE 1275 code for "nextprop". Use the common Open Firmware PCI interrupt routing code instead of the duplicate version in dev/fdt. Configure interrupt sense based on device tree information.

Make OF_nextprop() work correctly for FDT by using the libfdt fdt_next_property_offset() API. Do not panic if pmap_mincore() is called. An addendum: it is possible, though of questionable utility, for a node to have no properties at all. Add definition for the Atheros 8021 gigabit PHY. Consolidate Apple firmware hacks and improve them by switching on the presence of mac-io devices in the tree, which uniquely identifies Apple hardware. Allow OF_decode_addr() to also be able to map resources on big-endian devices. Make tsec work with the device tree present on the RB800. Be more flexible about which compatible strings to accept. This brings up the PCI Express bus on the RB800 using the firmware device tree. Rename the "bare" platform "mpc85xx", which is what it actually is, and add actual platform probing based on PVR.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add two new interfaces to ofw_bus: - ofw_bus_map_intr() Maps an (iparent, IRQ) tuple to a system-global interrupt number in some platform dependent way. This is meant to be implemented as a replacement for [FDT_]MAP_IRQ() that is an MI interface that knows about the bus hierarchy. - ofw_bus_config_intr() Configures an interrupt (previously mapped) based on firmware sense flags. This replaces manual interpretation of the sense field in bus drivers and will, in a follow-up, allow that interpretation to be redirected to the PIC drivers where it belongs. This will eventually replace the tables in /sys/dev/fdt/fdt_ARCH.c The PowerPC/AIM code has been converted to use these globally, with an implementation in terms of MAP_IRQ() and powerpc_config_intr(), assuming OpenPIC, at the bus root in nexus(4). The ofw_bus_config_intr() will shortly be integrated into pic_if.m and bounced through nexus into the PIC tree. Factor out MI portions of the PowerPC nexus device into /sys/dev/ofw. The sparc64 driver will be modified to use this shortly. Allow PIC drivers to translate firmware sense codes for themselves. This is designed to replace the tables in dev/fdt/fdt_ARCH.c, but will not happen quite yet. Do not map IRQs twice. This fixes PowerPC/FDT systems with multiple PICs, which would try to treat the previously-mapped interrupts from fdt_decode_intr() as interrupt line numbers on the same parent PIC. Remove some of the code required for supporting ssm(4) on SPARC in favor of a more PowerPC/FDT-focused design. Whenever SPARC64 is integrated into this rework, this should be (trivially) revisited.

Specifically, it takes a set of 32-bit cell values and changes them to host byte order.

| | | | | | | | | | | | | | | | | | | | Begin reducing code duplication in arm pmap.c and pmap-v6.c by factoring out common code related to mapping device memory into a new devmap.c file. Remove the growing duplication of code that used pmap_devmap_find_pa() and then did some math with the returned results to generate a virtual address, and likewise in reverse to get a physical address. Now there are a pair of functions, arm_devmap_vtop() and arm_devmap_ptov(), to do that. The bus_space_map() implementations are rewritten in terms of these. Move remaining code and data related to static device mapping into the new devmap.[ch] files. Emphasize the MD nature of these things by using the prefix arm_devmap_ on the function and type names (already a few of these things found their way into MI code, hopefully it will be harder to do by accident in the future).

FDT addresses are I/O ports on x86. Since the core FDT code does not handle different address spaces, adding support for both I/O ports and memory addresses requires some thought and discussion.

Modify debug printf in fdt_reg_to_rl() to be consistent (that is, print start and end *virtual* addresses). r230560: Handle "ranges;" Make fdt_reg_to_rl() responsible for mapping the device memory, instead on just hoping that there's only one simplebus, and using fdt_immr_va as the base VA. r230315 Add a function to get the PA from range, instead of (ab)using fdt_immr_pa, and use it for the UART driver Notes: svn path=/head/; revision=239274

Have the bus_config_intr and bus_teardown_intr methods implemented by bus_generic_config_intr and bus_generic_teardown_intr (resp) as we don't need to do anything special outselves. This removes all the ``#ifdef $arch'' code that was there because powerpc didn't have a proper nexus and people tend to copy and paste stuff. Notes: svn path=/head/; revision=238043
