| * | | pci: tegra: implement PCA enable workaroundStephen Warren2015-11-121-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tegra210's PCIe controller has a bug that requires the PCA (performance counter) feature to be enabled. If this isn't done, accesses to device configuration space will hang the chip for tens of seconds. Implement the workaround.

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | Tegra peripherals can generally access a 32-bit physical address space, and I believe this applies to PCIe. Clip the PCI region that refers to DRAM so it fits into 32-bits to avoid issues. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>

* | | pci: fix checking PCI_REGION_MEM in pci_hose_phys_to_bus()Cheng Gu2015-11-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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.
