* dm: x86: minnowmax: Move PCI to use driver modelSimon Glass2015-07-14-0/+10
| | | | | | | | | Adjust minnowmax to use driver model for PCI. This requires adding a device tree node to specify the ranges, removing the board-specific PCI code and ensuring that the host bridge is configured.

* x86: queensbay: Change PCIe root ports' interrupt routingBin Meng2015-07-14-4/+16
| | | | | | | | | | | | | | | So far interrupt routing works pretty well for any on-chip devices on Intel Crown Bay. When inserting any PCIe card to any PCIe slot, Linux kernel is smart enough to do interrupt swizzling and figure out device's irq using its parent bridge's interrupt routing info all the way up to its root port. In U-Boot all PCIe root ports' interrupts were routed to PIRQ E/F/G/H before, while actually all PCIe downstream ports received INTx are routed to PIRQ A/B/C/D directly and not configurable. Now we change this mapping so that any external PCIe device can work correctly. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
* x86: queensbay: Correct Topcliff device irqsBin Meng2015-07-14-12/+12
| | | | | | | | | | | | | | | There are 4 usb ports on the Intel Crown Bay board, 2 of which are connected to Topcliff usb host 0 and the other 2 connected to usb host 1. USB devices inserted in the ports connected to usb host 1 cannot get detected due to wrong IRQ assigned to the controller. Actually we need apply the PCI interrupt pin swizzling logic to all devices on the Topcliff chipset when configuring the PIRQ routing. This was observed on usb ports, but device 6 and 10 irqs are also wrong. Correct them all together. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>

* x86: Refactor PIRQ routing supportBin Meng2015-06-04-0/+54
| | | | | | | | | | | | PIRQ routing is pretty much common in Intel chipset. It has several PIRQ links (normally 8) and corresponding registers (either in PCI configuration space or memory-mapped IBASE) to configure the legacy 8259 IRQ vector mapping. Refactor current Queensbay PIRQ routing support using device tree and move it to a common place, so that we can easily add PIRQ routing support on a new platform.

| | | | | | | | | | | | | | | | Move chromebook_link over to driver model for PCI. This involves: - adding a uclass for platform controller hub - removing most of the existing PCI driver - adjusting how CPU init works to use driver model instead - rename the lpc compatible string (it will be removed later) This does not really take advantage of driver model fully, but it does work. Furture work will improve the code structure to remove many of the explicit calls to init the board. Signed-off-by: Simon Glass <sjg@chromium.org>

* x86: ivybridge: Implement SDRAM initSimon Glass2014-11-21-0/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement SDRAM init using the Memory Reference Code (mrc.bin) provided in the board directory and the SDRAM SPD information in the device tree. This also needs the Intel Management Engine (me.bin) to work. Binary blobs everywhere: so far we have MRC, ME and microcode. SDRAM init works by setting up various parameters and calling the MRC. This in turn does some sort of magic to work out how much memory there is and the timing parameters to use. It also sets up the DRAM controllers. When the MRC returns, we use the information it provides to map out the available memory in U-Boot. U-Boot normally moves itself to the top of RAM. On x86 the RAM is not generally contiguous, and anyway some RAM may be above 4GB which doesn't work in 32-bit mode. So we relocate to the top of the largest block of RAM we can find below 4GB. Memory above 4GB is accessible with special functions (see physmem). It would be possible to build U-Boot in 64-bit mode but this wouldn't necessarily provide any more memory, since the largest block is often below 4GB. Anyway U-Boot doesn't need huge amounts of memory - even a very large ramdisk seldom exceeds 100-200MB. U-Boot has support for booting 64-bit kernels directly so this does not pose a limitation in that area. Also there are probably parts of U-Boot that will not work correctly in 64-bit mode. The MRC is one. There is some work remaining in this area. Since memory init is very slow (over 500ms) it is possible to save the parameters in SPI flash to speed it up next time. Suspend/resume support is not fully implemented, or at least it is not efficient. With this patch, link boots to a prompt. Signed-off-by: Simon Glass <sjg@chromium.org>
