2014-06-20dm: Update README to encourage conversion to driver modelSimon Glass
Add a note to encourage people to convert drivers to use driver model. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-06-20Add an I/O tracing featureSimon Glass
When debugging drivers it is useful to see what I/O accesses were done and in what order. Even if the individual accesses are of little interest it can be useful to verify that the access pattern is consistent each time an operation is performed. In this case a checksum can be used to characterise the operation of a driver. The checksum can be compared across different runs of the operation to verify that the driver is working properly. In particular, when performing major refactoring of the driver, where the access pattern should not change, the checksum provides assurance that the refactoring work has not broken the driver. Add an I/O tracing feature and associated commands to provide this facility. It works by sneaking into the io.h heder for an architecture and redirecting I/O accesses through its tracing mechanism. For now no commands are provided to examine the trace buffer. The format is fairly simple, so 'md' is a reasonable substitute. Note: The checksum feature is only useful for I/O regions where the contents do not change outside of software control. Where this is not suitable you can fall back to manually comparing the addresses. It might be useful to enhance tracing to only checksum the accesses and not the data read/written.

2014-06-05bootm: make use of legacy image format configurableHeiko Schocher
make the use of legacy image format configurable through the config define CONFIG_IMAGE_FORMAT_LEGACY. When relying on signed FIT images with required signature check the legacy image format should be disabled. Therefore introduce this new define and enable legacy image format if CONFIG_FIT_SIGNATURE is not set. If CONFIG_FIT_SIGNATURE is set disable per default the legacy image format.

2014-06-01usb: hub: remove CONFIG_USB_HUB_MIN_POWER_ON_DELAYStephen Warren
Now that we wait the correct specification-mandated time at the end of usb_hub_power_on(), I suspect that CONFIG_USB_HUB_MIN_POWER_ON_DELAY has no purpose. For cm_t35.h, we already wait longer than the original MIN_POWER_ON_DELAY, so this change is safe. For gw_ventana.h, we will wait as long as the original MIN_POWER_ON_DELAY iff pgood_delay was at least 200ms. I'm not sure if this is the case or not, hence I've CC'd relevant people to test this change.

2014-05-08usb/gadget: add the fastboot gadgetSebastian Siewior
This patch contains an implementation of the fastboot protocol on the device side and documentation. This is based on USB download gadget infrastructure. The fastboot function implements the getvar, reboot, download and reboot commands. What is missing is the flash handling i.e. writting the image to media. v3 (Rob Herring): This is based on http://patchwork.ozlabs.org/patch/126798/ with the following changes: - Rebase to current mainline and updates for current gadget API - Use SPDX identifiers for licenses - Traced the history and added missing copyright to cmd_fastboot.c - Use load_addr/load_size for transfer buffer - Allow vendor strings to be optional - Set vendor/product ID from config defines - Allow Ctrl-C to exit fastboot mode v4: - Major re-write to use the USB download gadget. Consolidated function code to a single file. - Moved globals into single struct. - Use puts and putc as appropriate. - Added CONFIG_USB_FASTBOOT_BUF_ADDR and CONFIG_USB_FASTBOOT_BUF_SIZE to set the fastboot transfer buffer. v5: - Add CONFIG option documentation to README - Rebase using new downloader registration Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Rob Herring <robh@kernel.org>
2014-05-05usb: dfu: fix boards wo USB cable detectionMateusz Zalega
Former usb_cable_connected() patch broke compilation of boards which do not support this feature. I've renamed usb_cable_connected() to g_dnl_usb_cable_connected() and added its default implementation to gadget downloader driver code. There's only one driver of this kind and it's unlikely there'll be another, so there's no point in keeping it in /common. Previously this function was declared in usb.h. I've moved it, since it's more appropriate to keep it in g_dnl.h - usb.h seems to be intended for USB host implementation. Existing code, confronted with default -EOPNOTSUPP return value, continues as if the cable was connected. CONFIG_USB_CABLE_CHECK was removed.

Changes: 1. L2 cache is being invalidated by Boot ROM code for e6500 core. So removing the invalidation from start.S 2. Clear the LAW and corresponding configuration for CPC. Boot ROM code uses it as hosekeeping area. 3. For Secure boot, CPC is configured as SRAM and used as house keeping area. This configuration is to be disabled once in uboot. Earlier this disabling of CPC as SRAM was happening in cpu_init_r. As a result cache invalidation function was getting skipped in case CPC is configured as SRAM.This was causing random crashes.

2014-03-23usb: dfu: introduce dfuMANIFEST stateHeiko Schocher
on nand flash using ubi, after the download of the new image into the flash, the "rest" of the nand sectors get erased while flushing the medium. With current u-boot version dfu-util may show: Starting download: [##################################################] finished! state(7) = dfuMANIFEST, status(0) = No error condition is present unable to read DFU status as get_status is not answered while erasing sectors, if erasing needs some time. So do the following changes to prevent this: - introduce dfuManifest state According to dfu specification ( http://www.usb.org/developers/devclass_docs/usbdfu10.pdf ) section 7: "the device enters the dfuMANIFEST-SYNC state and awaits the solicitation of the status report by the host. Upon receipt of the anticipated DFU_GETSTATUS, the device enters the dfuMANIFEST state, where it completes its reprogramming operations." - when stepping into dfuManifest state, sending a PollTimeout DFU_MANIFEST_POLL_TIMEOUT in ms, to the host, so the host (dfu-util) waits the PollTimeout before sending a get_status again.

2014-02-26arm: Switch to -mno-unaligned-access when supported by the compilerTom Rini
When we tell the compiler to optimize for ARMv7 (and ARMv6 for that matter) it assumes a default of SCTRL.A being cleared and unaligned accesses being allowed and fast at the hardware level. We set this bit and must pass along -mno-unaligned-access so that the compiler will still breakdown accesses and not trigger a data abort. To better help understand the requirements of the project with respect to unaligned memory access, the Documentation/unaligned-memory-access.txt file has been added as doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1 tag of the kernel.
