* fastboot: check for alias when looking up partition by nameMichael Scott2015-04-14-0/+9
| | | | | | | | | | | | | | | | | Implement an alias name check for devices where GPT limitations prevent user-friendly partition names such as "boot", "system" and "cache". Or, where the actual partition name doesn't match a standard partition name used commonly with fastboot. To set an alias, add an environment setting as follows: fastboot_partition_alias_<alias partition name>=<actual partition name> Example: fastboot_partition_alias_boot=LNX Signed-off-by: Michael Scott <michael.scott@linaro.org> Acked-by: Steve Rae <srae@broadcom.com> Cc: Steve Rae <srae@broadcom.com> Cc: Lukasz Majewski <l.majewski@samsung.com>
* usb: gadget: fastboot: Add fastboot eraseDileep Katta2015-02-25-3/+2
| | | | | | | | | | | | Adds the fastboot erase functionality, to erase a partition specified by name. The erase is performed based on erase group size, to avoid erasing other partitions. The start address and the size is aligned to the erase group size for this. Currently only supports erasing from eMMC.

* doc: README.android-fastboot: Add note about vendor IDBarnes, Clifton A2014-08-09-0/+4
| | | | | | | | | | The Android fastboot client only communicates with specific vendor IDs. This addition to the documentation points out that fact so everyone is aware that not just any vendor ID will work and where to find the IDs that will.

* usb/gadget: add the fastboot gadgetSebastian Siewior2014-05-08-0/+91
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>
