* 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>
* 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>

If the boot operation is aborted, this global state is not cleared. If "dhcp" is executed later without any arguments, BootFile is not cleared, and when the DHCP response is received, BootpCopyNetParams() writes the value into environment variable bootfile. This causes the following scenario: * Boot script executes dhcp; pxe get; pxe boot * User CTRL-C's the PXE menu, which causes the first menu item to be booted, which causes some file to be downloaded. (This boot-on-CTRL-C behaviour is arguably a bug too, but it's a separate bug and the bug this patch fixes would still exist if the user simply waited to press CTRL-C until "pxe boot" started downloading files) * User CTRL-C's the file downloads, but the filename is still written to the bootfile environment variable. * User re-runs the boot command, which in my case executes "dhcp; pxe get; pxe boot" again, and "dhcp" picks up the saved bootfile environment variable and proceeds to download a file that it shouldn't. To solve this, modify the implementation of "pxe get" to clear BootFile if the whole boot operation fails, which avoids this whole mess. An alternative would be to modify netboot_common() such that the no- arguments case explicitly clears the global variable BootFile. However, that would prevent the following command sequences from working: $ dhcp filename # downloads "filename" $ dhcp # downloads $bootfile, i.e. "filename" or: $ setenv bootfile filename $ dhcp # downloads $bootfile, i.e. "filename" ... and I assume someone relies on U-Boot working that way.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Driver model currently only operates after relocation is complete. In this state U-Boot typically has a small amount of memory available. In adding support for driver model prior to relocation we must try to use as little memory as possible. In addition, on some machines the memory has not be inited and/or the CPU is not running at full speed or the data cache is off. These can reduce execution performance, so the less initialisation that is done before relocation the better. An immediately-obvious improvement is to only initialise drivers which are actually going to be used before relocation. On many boards the only such driver is a serial UART, so this provides a very large potential benefit. Allow drivers to mark themselves as 'pre-reloc' which means that they will be initialised prior to relocation. This can be done either with a driver flag or with a 'dm,pre-reloc' device tree property. To support this, the various dm scanning function now take a 'pre_reloc_only' parameter which indicates that only drivers marked pre-reloc should be bound.

* | stdio: Pass device pointer to stdio methodsSimon Glass2014-07-23-25/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present stdio device functions do not get any clue as to which stdio device is being acted on. Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away.

* | Add a simple malloc() implementation for pre-relocationSimon Glass2014-07-23-0/+51

The standard malloc() is pretty complicated: 1. It uses some BSS memory for its state, and BSS is not available before relocation 2. It supports algorithms for reducing memory fragmentation and improving performace of free(). Before relocation we could happily just not support free(). 3. It includes about 4KB of code (Thumb 2) and 1KB of data. However since this has been loaded anyway this is not really a problem. The simplest way to support pre-relocation malloc() is to reserve an area of memory and allocate it in increasing blocks as needed. This implementation does this. To enable it, you need to define the size of the malloc() pool as described in the README. It will be located above the pre-relocation stack on supported architectures. Note that this implementation is only useful on machines which have some memory available before dram_init() is called - this includes those that do no DRAM init (like tegra) and those that do it in SPL (quite a few boards). Enabling driver model preior to relocation for the rest of the boards is left for a later exercise. Signed-off-by: Simon Glass <sjg@chromium.org>

On the other hand they show up as annoying control characters in my editor, which then happily removes them. I believe we can drop these characters from the file.

* | board_r: run scsi init() on ARM tooIan Campbell2014-07-22-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This has been disabled for ARM in initr_scsi since that function was introduced. However it works fine for me on Cubieboard and Cubietruck (with the upcoming AHCI glue patch). I also tested on two random ARM platforms which seem to define CONFIG_CMD_SCSI: - highbank worked fine (on midway hardware) - omap5_uevm built OK and I confirmed using objdump that things were as expected (i.e. the default weak scsi_init nop was used). While there remove the mismatched comment from the #endif (omitting the comment seems to be the prevailing style in this file).
