* x86: queensbay: Implement PIRQ routingBin Meng2015-04-29-2/+188
| | | | | | | | Implement Intel Queensbay platform-specific PIRQ routing support. The chipset PIRQ routing setup is called in the arch_misc_init(). Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
* x86: Support platform PIRQ routingBin Meng2015-04-29-0/+139
| | | | | | | | | | | | | | | On x86 boards, platform chipset receives up to four different interrupt signals from PCI devices (INTA/B/C/D), which in turn will be routed to chipset internal PIRQ lines then routed to 8259 PIC finally if configuring the whole system to work under the so-called PIC mode (in contrast to symmetric IO mode which uses IOAPIC). We add two major APIs to aid this, one for routing PIRQ and the other one for generating a PIRQ routing table. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>

* dm: x86: spi: Convert ICH SPI driver to driver modelSimon Glass2015-04-18-2/+2
| | | | | | | | | | | | Convert this driver over to use driver model. Since all x86 platforms use it, move x86 to use driver model for SPI and SPI flash. Adjust all dependent code and remove the old x86 spi_init() function. Note that this does not make full use of the new PCI uclass as yet. We still scan the bus looking for the device. It should move to finding its details in the device tree. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: x86: pci: Convert chromebook_link to use driver model for pciSimon Glass2015-04-18-1/+0
| | | | | | | | | | | | | | | | 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: Add a x86_ prefix to the x86-specific PCI functionsSimon Glass2015-04-16-6/+6
| | | | | | | | | | | | These functions currently use a generic name, but they are for x86 only. This may introduce confusion and prevents U-Boot from using these names more widely. In fact it should be possible to remove these at some point and use generic functions, but for now, rename them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a relatively low-cost x86 board in a small form factor. The main peripherals are uSD, USB, HDMI, Ethernet and SATA. It uses an Atom 3800 series CPU. So far only the dual core 2GB variant is supported. This uses the existing FSP support. Binary blobs are required to make this board work. The microcode update is included as a patch (all 3000 lines of it).

| | | | | | | | | | | At present the normal update (which happens much later) does not work. This seems to have something to do with the 'no eviction' mode in the CAR, or at least moving the microcode update after that causes it not to work.

* x86: Support Intel FSP initialization path in start.SBin Meng2014-12-13-0/+3
| | | | | | | | | | | | | | | | | Per Intel FSP architecture specification, FSP provides 3 routines for bootloader to call. The first one is the TempRamInit (aka Cache-As-Ram initialization) and the second one is the FspInit which does the memory bring up (like MRC for other x86 targets) and chipset initialization. Those two routines have to be called before U-Boot jumping to board_init_f in start.S. The FspInit() will return several memory blocks called Hand Off Blocks (HOBs) whose format is described in Platform Initialization (PI) specification (part of the UEFI specication) to the bootloader.
