2015-11-12pci: fix checking PCI_REGION_MEM in pci_hose_phys_to_bus()Cheng Gu
When converting between PCI bus and phys addresses, a two pass search was introduced with preference to non-PCI_REGION_SYS_MEMORY regions. See commit 2d43e873a29ca4959ba6a30fc7fb396d3fd0dccf. However, since PCI_REGION_MEM is defined as 0, the if statement was always asserted true: ((flags & PCI_REGION_MEM) == PCI_REGION_MEM) This patch uses PCI_REGION_TYPE bit to check if the region is PCI_REGION_MEM: ((flags & PCI_REGION_TYPE) == PCI_REGION_MEM) Signed-off-by: Cheng Gu <chenggu@marvell.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2015-11-12fastboot: Implement NAND backendMaxime Ripard
So far the fastboot code was only supporting MMC-backed devices for its flashing operations (flash and erase). Add a storage backend for NAND-backed devices. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
2015-11-12fastboot: Implement flashing session counterMaxime Ripard
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.

2015-11-10Various Makefiles: Add SPDX-License-Identifier tagsTom Rini
After consulting with some of the SPDX team, the conclusion is that Makefiles are worth adding SPDX-License-Identifier tags too, and most of ours have one. This adds tags to ones that lack them and converts a few that had full (or in one case, very partial) license blobs into the equivalent tag.
