* x86: Enable PCIe controller on quark/galileoBin Meng2015-09-09-0/+161
| | | | | | | | | | | | | Quark SoC holds the PCIe controller in reset following a power on. U-Boot needs to release the PCIe controller from reset. The PCIe controller (D23:F0/F1) will not be visible in PCI configuration space and any access to its PCI configuration registers will cause system hang while it is held in reset. Enable PCIe controller per Quark firmware writer guide. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
* x86: quark: Avoid chicken and egg problemBin Meng2015-09-09-15/+15
| | | | | | | | | | | | | | | | | | | | If we convert to use driver model pci on quark, we will encounter some chicken and egg problems like below: - To enable PCIe root ports, we need program some registers on the message bus via pci bus. With driver model, the first time to access pci bus, the pci enumeration process will be triggered. But without first enabling PCIe root ports, pci enumeration just hangs when scanning PCIe root ports. - Similar situation happens when trying to access GPIO from the PCIe enabling codes, as GPIO requires its block base address to be assigned via a pci configuration register in the bridge. To avoid such dilemma, replace all pci calls in the quark codes to use the local version which does not go through driver model.

* x86: quark: Optimize MRC execution timeBin Meng2015-09-09-22/+57
| | | | | | | | | | | | | | | | | Intel Quark SoC has a low end x86 processor with only 400MHz frequency. Currently it takes about 15 seconds for U-Boot to boot to shell and the most time consuming part is with MRC, which is about 12 seconds. MRC programs lots of registers on the SoC internal message bus indirectly accessed via pci bus. To speed up the boot, create an optimized version of pci config read/write dword routines which directly operate on PCI I/O ports. These two routines are inlined to provide better performance too. Now it only takes about 3 seconds to finish MRC, which is really fast (4 times faster than before). Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
* dm: pci: Allow a PCI bus to be found without an aliasSimon Glass2015-09-09-4/+24
| | | | | | | | | | | | | | At present, until a PCI bus is probed, it cannot be found by its sequence number unless it has an alias. This is the same with any device. However with PCI this is more annoying than usual, since bus 0 is always the same device. Add a function that tries a little harder to locate PCI bus 0. This means that PCI enumeration will happen automatically on the first access. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* buildman: Improve the config comparison featureSimon Glass2015-09-09-44/+142
| | | | | | | | | | | | | | | | At present buildman can compare configurations between commits but the feature is less useful than it could be. There is no summary by architecture and changes are not reported on a per-board basis. Correct these deficiencies so that it is possible to see exactly what is changing for any number of boards. Note that 'buildman -b <branch> -C' is recommended for any build where you will be comparing configuration. Without -C the correct configuration will not be reported since changes will often not be picked up.

* Revert "patman: use -D option for git format-patch"Masahiro Yamada2015-09-09-1/+1
| | | | | | | | | | | | | | | | | | | | | | This reverts commit 19b4a3369876f9215e2b861f211e8df1a75e26ca. Since that commit, patman generates useless patches for file removal; "git format -D" prints only the header but not the diff when deleting files, and "git am" always refuses such patches. The following is the quotation from "man git-format-patch": -D, --irreversible-delete Omit the preimage for deletes, i.e. print only the header but not the diff between the preimage and /dev/null. The resulting patch is not meant to be applied with patch nor git apply; this is solely for people who want to just concentrate on reviewing the text after the change. In addition, the output obviously lack enough information to apply such a patch in reverse, even manually, hence the name of the option.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Consequently, when the device is deregistered, ehci_shutdown() will fail, since the HW bits it expects to see set in response to its shutdown requests will not be sent, and the message "EHCI failed to shut down host controller." will be printed. Fix ehci-hcd.c to remember whether the device was registered in host or device mode, and only call ehci_shutdown() for host mode registrations. Signed-off-by: Stephen Warren <swarren@nvidia.com>
