* [ARM] Kirkwood: disable propagation of mbus error to the CPU local busLennert Buytenhek2009-11-13
| | | | | | | | | | Disable propagation of mbus errors to the CPU local bus, as this causes mbus errors (which can occur for example for PCI aborts) to throw CPU aborts, which we're not set up to deal with.

* [ARM] kirkwood: fix PCI I/O port assignmentLennert Buytenhek2009-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | Instead of allocating PCI devices I/O port bus addresses from the 000xxxxx I/O port range as intended, due to a bus versus physical address mixup, the Kirkwood PCIe handling code inadvertently allocated I/O port bus addresses from the f20xxxxx address range (which is the physical address range of the PCIe I/O mapping window), but then direct all I/O port accesses to bus addresses 000xxxxx, which would then not be decoded at all. Fix this by setting the base address of the PCIe I/O space struct resource to KIRKWOOD_PCIE_IO_BUS_BASE instead of the incorrect KIRKWOOD_PCIE_IO_PHYS_BASE, and fix up __io() to expect addresses offsetted by the former instead of the latter. (The suggested fix of directing I/O port accesses from the host to bus addresses f20xxxxx instead has the problem that assigning full 32bit I/O port bus addresses (f20xxxxx) doesn't work on all PCI devices, as not all PCI devices implement full 32 bit BAR registers for I/O ports. We should really try to allocate I/O port bus addresses that fit in 16 bits.) Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: Nicolas Pitre <nico@marvell.com>

This affects mach-kirkwood, mach-loki, mach-mv78xx0 and mach-orion5x simultaneously as they all share code in plat-orion which relies on those defines. Some other defines have been moved to narrower scopes, or simply deleted when they had no user. This fixes compilation problem with mpt2sas on the above listed platforms.

| * dsa: add switch chip cascading supportLennert Buytenhek2009-03-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The initial version of the DSA driver only supported a single switch chip per network interface, while DSA-capable switch chips can be interconnected to form a tree of switch chips. This patch adds support for multiple switch chips on a network interface. An example topology for a 16-port device with an embedded CPU is as follows: +-----+ +--------+ +--------+ | |eth0 10| switch |9 10| switch | | CPU +----------+ +-------+ | | | | chip 0 | | chip 1 | +-----+ +---++---+ +---++---+ || || || || ||1000baseT ||1000baseT ||ports 1-8 ||ports 9-16 This requires a couple of interdependent changes in the DSA layer: - The dsa platform driver data needs to be extended: there is still only one netdevice per DSA driver instance (eth0 in the example above), but each of the switch chips in the tree needs its own mii_bus device pointer, MII management bus address, and port name array. (include/net/dsa.h) The existing in-tree dsa users need some small changes to deal with this. (arch/arm) - The DSA and Ethertype DSA tagging modules need to be extended to use the DSA device ID field on receive and demultiplex the packet accordingly, and fill in the DSA device ID field on transmit according to which switch chip the packet is heading to. (net/dsa/tag_{dsa,edsa}.c) - The concept of "CPU port", which is the switch chip port that the CPU is connected to (port 10 on switch chip 0 in the example), needs to be extended with the concept of "upstream port", which is the port on the switch chip that will bring us one hop closer to the CPU (port 10 for both switch chips in the example above). - The dsa platform data needs to specify which ports on which switch chips are links to other switch chips, so that we can enable DSA tagging mode on them. (For inter-switch links, we always use non-EtherType DSA tagging, since it has lower overhead. The CPU link uses dsa or edsa tagging depending on what the 'root' switch chip supports.) This is done by specifying "dsa" for the given port in the port array. - The dsa platform data needs to be extended with information on via which port to reach any given switch chip from any given switch chip. This info is specified via the per-switch chip data struct ->rtable[] array, which gives the nexthop ports for each of the other switches in the tree. For the example topology above, the dsa platform data would look something like this: static struct dsa_chip_data sw[2] = { { .mii_bus = &foo, .sw_addr = 1, .port_names[0] = "p1", .port_names[1] = "p2", .port_names[2] = "p3", .port_names[3] = "p4", .port_names[4] = "p5", .port_names[5] = "p6", .port_names[6] = "p7", .port_names[7] = "p8", .port_names[9] = "dsa", .port_names[10] = "cpu", .rtable = (s8 []){ -1, 9, }, }, { .mii_bus = &foo, .sw_addr = 2, .port_names[0] = "p9", .port_names[1] = "p10", .port_names[2] = "p11", .port_names[3] = "p12", .port_names[4] = "p13", .port_names[5] = "p14", .port_names[6] = "p15", .port_names[7] = "p16", .port_names[10] = "dsa", .rtable = (s8 []){ 10, -1, }, }, }, static struct dsa_platform_data pd = { .netdev = &foo, .nr_switches = 2, .sw = sw, }; Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Tested-by: Gary Thomas <gary@mlbassoc.com> Signed-off-by: David S.

|/ | | | | | | | | | | | | | | OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.

* [ARM] 5401/1: Orion: fix edge triggered GPIO interrupt supportNicolas Pitre2009-02-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GPIO interrupts can be configured as either level triggered or edge triggered, with a default of level triggered. When an edge triggered interrupt is requested, the gpio_irq_set_type method is called which currently switches the given IRQ descriptor between two struct irq_chip instances: orion_gpio_irq_level_chip and orion_gpio_irq_edge_chip. This happens via __setup_irq() which also calls irq_chip_set_defaults() to assign default methods to uninitialized ones. The problem is that irq_chip_set_defaults() is called before the irq_chip reference is switched, leaving the new irq_chip (orion_gpio_irq_edge_chip in this case) with uninitialized methods such as chip->startup() causing a kernel oops. Many solutions are possible, such as making irq_chip_set_defaults() global and calling it from gpio_irq_set_type(), or calling __irq_set_trigger() before irq_chip_set_defaults() in __setup_irq(). But those require modifications to the generic IRQ code which might have adverse effect on other architectures, and that would still be a fragile arrangement. Manually copying the missing methods from within gpio_irq_set_type() would be really ugly and it would break again the day new methods with automatic defaults are added. A better solution is to have a single irq_chip instance which can deal with both edge and level triggered interrupts. It is also a good idea to switch the IRQ handler instead, as the edge IRQ handler allows for one edge IRQ event to be queued as the IRQ is actually masked only when that second IRQ is received, at which point the hardware can queue an additional IRQ event, making edge triggered interrupts a bit more reliable.
