* fdt_support: Make of_bus_default_count_cells non staticArnab Basu2014-09-25-1/+1
| | | | | | | | | | of_bus_default_count_cells can be used to get the #address-cells and #size-cells defined by the current node's parent node. This is required when using of_read_number to read from FDT nodes that can be 32 or 64 bytes depending on values defined by the parent.

* kgdb: Remove first_entry for kgdbPeng Fan2014-09-16-12/+2
| | | | | | | | | | | | | | | | | | | | | There are two ways to run into handle_exception, run command 'kgdb' and encounter a breakpoint which triggers exception handling. The origin source code only saves regs when first run command 'kgdb'. Take the following for example, When run 'kgdb', regs is saved to entry_regs. When run 'bootz', regs is not saved. However, if we set a breakpoint, then continue. When breakpoint is reached, run `quit`, and Now return to the instruction which follows kgdb, but not bootz.This may cause errors. So, save regs for each handle_exception call to return to the correct place. Example: Target | Host =>kgdb | (gdb)b bootz | (gdb)c =>bootz | | (gdb)Here stop because of breakpoint | (gdb)q Signed-off-by: Peng Fan <van.freenix@gmail.com>

| * dm: Make driver model available before board_init()Simon Glass2014-09-10-15/+27
| | | | | | | | | | | | | | | | | | | | | | For some boards board_init() will change GPIOs, so we need to have driver model available before then. Adjust the board init to arrange this, but enable it for driver model only, just to be safe. This does create additional #ifdef logic, but it is safer than trying to make a pervasive change which may cause some boards to break. Signed-off-by: Simon Glass <sjg@chromium.org>
| * Set up stdio earlier when using driver modelSimon Glass2014-09-10-6/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | Since driver model registers itself with the stdio subsystem, and we want to avoid delayed registration and other complexity associated with the current serial console, move the stdio subsystem init earlier when driver model is used for serial. This simplifies the implementation. Should there be any problems with this approach they can be dealt with as boards are converted over to use driver model for serial.

| | | | | | | | | | | | | | | | | | In order to support GPIO access in board_early_init_f() we must set up driver model before this function is called. In any case, earlier is better since driver model is (or will become) a key function for most init. Signed-off-by: Simon Glass <sjg@chromium.org>

| * dfu: Provide means to find difference between dfu-util -e and -RLukasz Majewski2014-09-02-4/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit provides distinction between DFU device detach and reset. The -R behavior is preserved with proper handling of the dfu-util's -e switch, which detach the DFU device. By running dfu-util -e; one can force device to finish the execution of dfu command on target and execute some other scripted commands. Moreover, some naming has been changed - the dfu_reset() method now is known as dfu_detach(). New name better reflects the purpose of the code. It was also necessary to increase the number of usb_gadget_handle_interrupts() calls since we also must wait for detection of the USB reset event. Example usage: 1. -e (detach) switch dfu-util -a0 -D file1.bin;dfu-util -a3 -D uImage;dfu-util -e access to u-boot prompt. 2. -R (reset) switch dfu-util -a0 -D file1.bin;dfu-util -R -a3 -D uImage target board reset Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Reviewed-by: Stephen Warren <swarren@nvidia.com> Tested-by: Stephen Warren <swarren@nvidia.com>
* | dm: gpio: Allow gpio command to adjust GPIOs that are busySimon Glass2014-08-31-3/+6
| | | | | | | | | | | | | | | | | | | | The gpio command mostly relies on gpio_request() and gpio_free() being nops, in that you can request a GPIO twice. With driver model this is now implemented correctly, so it fails. Change the command to deal with a failure to claim the GPIO. Signed-off-by: Simon Glass <sjg@chromium.org>
* | dm: gpio: Enhance gpio command to show only active GPIOsSimon Glass2014-08-31-32/+69
|/ | | | | | | | | | | | The GPIO list is very long in many cases and most of them are not used. By default, show only the GPIOs that are in use, and provide a flag to show all of them. This makes the 'gpio status' command much more pleasant. In order to do this, driver model now exposes a method for obtaining the 'function' of a GPIO, which describes whether it is an input or output, for example. Implementation of this method is optional. Signed-off-by: Simon Glass <sjg@chromium.org>
* cmd_bootm.c: Add 'booti' for ARM64 Linux kernel ImagesTom Rini2014-08-30-0/+140
| | | | | | | | | | | | | The default format for arm64 Linux kernels is the "Image" format, described in Documentation/arm64/booting.txt. This, along with an optional gzip compression on top is all that is generated by default. The Image format has a magic number within the header for verification, a text_offset where the Image must be run from, an image_size that includes the BSS and reserved fields. This does not support automatic detection of a gzip compressed image. Signed-off-by: Tom Rini <trini@ti.com>

For some reason, the device appears to briefly drop off the bus when this second bus reset is executed, yet if we retry this loop, it'll eventually come back after another two resets. If USB bus reset is executed over and over within usb_new_device()'s call to hub_port_reset(), I see the following sequence of results, which repeats as long as you want: 1) STAT_C_CONNECTION = 1 STAT_CONNECTION = 0 USB_PORT_STAT_ENABLE 0 2) STAT_C_CONNECTION = 1 STAT_CONNECTION = 1 USB_PORT_STAT_ENABLE 0 3) STAT_C_CONNECTION = 1 STAT_CONNECTION = 1 USB_PORT_STAT_ENABLE 1 The device in question is a SanDisk Ultra USB 3.0 16GB memory stick with USB VID/PID 0x0781/0x5581. In order to allow this device to work with U-Boot, ignore the {C_,}CONNECTION bits in the status/change registers, and only use the ENABLE bit to determine if the reset was successful. To be honest, extensive investigation has failed to determine why this problem occurs. I'd love to know! I don't know if it's caused by: * A HW bug in the device * A HW bug in the Tegra USB controller * A SW bug in the U-Boot Tegra USB driver * A SW bug in the U-Boot USB core This issue only occurs when the device's USB3 pins are attached to the host; if only the USB2 pins are connected the issue does not occur. The USB3 controller on Tegra is in reset, so is not actively communicating with the device at all - a USB3 analyzer confirms this. Slightly unplugging the device (so the USB3 pins don't contact) or using a USB2 cable or hub as an intermediary avoids the problem. For some reason, the Linux kernel (either on the same Tegra board, or on an x86 host) has no issue with the device, and I observe no disconnections during reset. This change won't affect any USB device that already works, since such devices could not currently be triggering the error return this patch removes, or they wouldn't be working currently. However, this patch is quite reliable in practice, hence I hope it's acceptable to solve the problem. The only potential fallout I can see from this patch is: * A broken device that triggers C_CONNECTION/!CONNECTION now causes the loop in hub_port_reset() to run multiple times. If it never succeeds, this will cause "usb start" to take roughly 1s extra to execute. * If the user unplugs a device while hub_port_reset() is executing, and very quickly swaps in a new device, hub_port_reset() might succeed on the new device. This would mean that any information cached about the original device (from the descriptor read in usb_new_device(), which simply caches the max packet size) might be invalid, which would cause problems talking to the new device. However, without this change, the new device wouldn't work anyway, so this is probably not much of a loss. Signed-off-by: Stephen Warren <swarren@nvidia.com>
