* x86: Convert microcode format to device-tree-onlySimon Glass2014-12-182-7/+11
| | | | | | | | | | To avoid having two microcode formats, adjust the build system to support obtaining the microcode from the device tree, even in the case where it must be made available before the device tree can be accessed.

* x86: Add basic support to queensbay platform and crownbay boardBin Meng2014-12-186-0/+326
| | | | | | | | | | | Implement minimum required functions for the basic support to queensbay platform and crownbay board. Currently the implementation is to call fsp_init() in the car_init(). We may move that call to cpu_init_f() in the future. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>

* x86: Correct problems in the microcode loadingSimon Glass2014-12-181-10/+15
| | | | | | | | | | | | | There are several problems in the code. The device tree decode is incorrect in ways that are masked due to a matching bug. Both are fixed. Also microcode_read_rev() should be inline and called before the microcode is written. Note: microcode writing does not work correctly on ivybridge for me. Further work is needed to resolve this. But this patch tidies up the existing code so that will be easier. Signed-off-by: Simon Glass <sjg@chromium.org>

* x86: move arch-specific asmlinkage to <asm/linkage.h>Masahiro Yamada2014-12-155-1/+11
| | | | | | | | | | | | | | | | | | Commit 65dd74a674d6 (x86: ivybridge: Implement SDRAM init) introduced x86-specific asmlinkage into arch/x86/include/asm/config.h. 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: Add a simple command to show FSP HOB informationBin Meng2014-12-132-0/+68
| | | | | | | | | | | | | | FSP builds a series of data structures called the Hand-Off-Blocks (HOBs) as it progresses through initializing the silicon. These data structures conform to the HOB format as described in the Platform Initialization (PI) specification Volume 3 Shared Architectual Elements specification, which is part of the UEFI specification. Create a simple command to parse the HOB list to display the HOB address, type and length in bytes. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
* x86: Support Intel FSP initialization path in start.SBin Meng2014-12-133-0/+20
| | | | | | | | | | | | | | | | | 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>

For more details, check http://www.intel.com/fsp. Note: U-Boot coding convention was applied to these codes, so it looks completely different from the original Intel release.

* Kbuild: introduce Makefile in arch/$ARCH/Daniel Schwierzeck2014-12-081-0/+12
| | | | | | | | | | | | | | | Introduce a Makefile under arch/$ARCH/ and include it in the top Makefile (similar to Linux kernel). This allows further refactoringi like moving architecture-specific code out of global makefiles, deprecating config variables (CPU, CPUDIR, SOC) or deprecating arch/$ARCH/config.mk. In contrary to Linux kernel, U-Boot defines the ARCH variable by Kconfig, thus the arch Makefile can only included conditionally after the top config.mk.
