* fastboot: Implement NAND backendMaxime Ripard2015-11-12-0/+11

* fastboot: Implement flashing session counterMaxime Ripard2015-11-12-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fastboot flash command that writes an image to a partition works in several steps: 1 - Retrieve the maximum size the device can download through the "max-download-size" variable 2 - Retrieve the partition type through the "partition-type:%s" variable, that indicates whether or not the partition needs to be erased (even though the fastboot client has minimal support for that) 3a - If the image is smaller than what the device can handle, send the image and flash it. 3b - If the image is larger than what the device can handle, create a sparse image, and split it in several chunks that would fit. Send the chunk, flash it, repeat until we have no more data to send. However, in the 3b case, the subsequent transfers have no particular identifiers, the protocol just assumes that you would resume the writes where you left it. While doing so works well, it also means that flashing two subsequent images on the same partition (for example because the user made a mistake) would not work withouth flashing another partition or rebooting the board, which is not really intuitive. Since we have always the same pattern, we can however maintain a counter that will be reset every time the client will retrieve max-download-size, and incremented after each buffer will be flashed, that will allow us to tell whether we should simply resume the flashing where we were, or start back at the beginning of the partition.

| | | | | | | | | | | | | | | | | | | | | | | | Using NAKs on empty RX fifo for bulk in transfers is the right choice for a interrupt driven model, but U-Boot uses polling and expects an immediate answer if there is no incoming packet. Using ZLP Bulk In Response (BIR) mode avoids unexpected timeouts in the host controller driver. As ZLP mode is reset default, there is no need to set it.

* usb: ci_udc: fix emissions of ZLPsStephen Warren2015-09-12-10/+8
| | | | | | | | | | | | | | | | | | | Commit 6a132416359e "ci_udc: Update the ci_udc driver to support bulk transfers" caused the value of "len" to change without updating subsquent users of that variable in ci_ep_submit_next_request(). This caused the code that detects when to emit ZLPs (Zero Length Packets) never to trigger, which in turn caused host timeouts when a ZLP was required, which in turn broke tests/dfu/, even despite the assertion in that commit's description that "These changes are tested for both the DFU and lthor." Fix this by modifying the added dtd iteration code not to modify "len", but rather to keep state in a separate variable. Rename the variables while we're at it so they describe their purpose better.

Looking at the surrounding code, I found the same problem in all other composite gadget drivers in both the bind and unbind functions, as well as the udc platform driver 'remove' functions. Those will break if anyone uses the 'unbind' sysfs attribute to detach a device from a built-in driver. This patch removes the incorrect annotations from all the gadget drivers.

| | | | | | | | | | | | | | When an EHCI device is registered in device mode, the HW isn't actually initialized at all, and hence isn't left in a running state.
