| * x86: quark: Initialize non-standard BARsBin Meng2015-02-06-0/+32
| | | | | | | | | | | | | | | | | | Quark SoC has some non-standard BARs (excluding PCI standard BARs) which need be initialized with suggested values. This includes GPIO, WDT, RCBA, PCIe ECAM and some ACPI register block base addresses. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>

| * x86: quark: Add routines to access message bus registersBin Meng2015-02-06-0/+106
| | | | | | | | | | | | | | | | | | | | | | In the Quark SoC, some chipset commands are accomplished by utilizing the internal message network within the host bridge (D0:F0). Accesses to this network are accomplished by populating the message control register (MCR), Message Control Register eXtension (MCRX) and the message data register (MDR).

| * x86: Add support for Intel Minnowboard MaxSimon Glass2015-02-06-0/+147
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | Since the FSP is a black box it helps to have some sort of debugging available to check its inputs. If the debug UART is in use, set it up after CAR is available. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

* x86: Implement a cache for Memory Reference Code parametersSimon Glass2015-01-24-0/+54
| | | | | | | | | | | The memory reference code takes a very long time to 'train' its SDRAM interface, around half a second. To avoid this delay on every boot we can store the parameters from the last training sessions to speed up the next. Add an implementation of this, storing the training data in CMOS RAM and SPI flash.

* x86: Test mtrr support flag before accessing mtrr msrBin Meng2015-01-23-1/+4
| | | | | | | | | | On some x86 processors (like Intel Quark) the MTRR registers are not supported. This is reflected by the CPUID (EAX 01H) result EDX[12]. Accessing the MTRR registers on such processors will cause #GP so we must test the support flag before accessing MTRR MSRs.

* x86: ivybridge: Update microcode early in bootSimon Glass2015-01-13-0/+6
| | | | | | | | | | | 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. For now, do an update early on so that it definitely works. Also refuse to continue unless the microcode update check (later in boot) is successful. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Add support for MTRRsSimon Glass2015-01-13-83/+89
| | | | | | | | | | | | | | Memory Type Range Registers are used to tell the CPU whether memory is cacheable and if so the cache write mode to use. Clean up the existing header file to follow style, and remove the unneeded code. These can speed up booting so should be supported. Add these to global_data so they can be requested while booting.

| | | | | | | | | | | | | | Introduce a gd->hose to save the pci hose in the early phase so that apis in drivers/pci/pci.c can be used before relocation. Architecture codes need assign a valid gd->hose in the early phase. Some variables are declared as static so change them to be either stack variable or global data member so that they can be used before relocation, except the 'indent' used by CONFIG_PCI_SCAN_SHOW which just affects some print format.

Commit ed0a2fbf14f7 (x86: Add a definition of asmlinkage) added the same macro define again, this time, into include/common.h. (Please do not add arch-specific stuff to include/common.h any more; it is already too cluttered.) The generic asmlinkage is defined in <linux/linkage.h>. If you want to override it with an arch-specific one, the best way is to add it to <asm/linkage.h> like Linux Kernel.

* 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. Save this HOB address to the U-Boot global data for later use. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
