2015-07-28x86: Reserve PCIe ECAM address range in the E820 tableBin Meng
We should mark PCIe ECAM address range in the E820 table as reserved otherwise kernel will not attempt to use ECAM. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>

2015-07-28x86: Allow cpu-x86 driver to be probed for UPBin Meng
Currently cpu-x86 driver is probed only for SMP. We add the same support for UP when there is only one cpu node in the deive tree. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
2015-07-28x86: qemu: Enable I/O APIC chip select on PIIX3Bin Meng
The PIIX3 chipset does not integrate an I/O APIC, instead it supports connecting to an external I/O APIC which needs to be enabled manually. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
2015-07-28x86: mpspec: Move writing ISA interrupt entry after PCIBin Meng
On some platforms the I/O APIC interrupt pin#0-15 may be connected to platform pci devices' interrupt pin. In such cases the legacy ISA IRQ is not available so we should not write ISA interrupt entry if it is already occupied.

2015-07-28x86: mpspec: Allow platform to determine how PIRQ is connected to I/O APICBin Meng
Currently during writing MP table I/O interrupt assignment entry, we assume the PIRQ is directly mapped to I/O APIC INTPIN#16-23, which however is not always the case on some platforms. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>

2015-07-28x86: Simplify architecture defined exception handling in irq_llsr()Bin Meng
Instead of using switch..case for architecture defined exceptions, simply unify the handling by printing a message of exception name, followed by registers dump then halt the CPU. With this unification, it also fixes the wrong exception numbers for #MF/#AC/#MC/#XM which should be 16/17/18/19 not 15/16/17/18.

2015-07-28x86: Display correct CS/EIP/EFLAGS when there is an error codeBin Meng
Some exceptions cause an error code to be saved on the current stack after the EIP value. We should extract CS/EIP/EFLAGS from different position on the stack based on the exception number. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>

2015-07-28ARM: zynq: DT: Remove 222 MHz OPPMichal Simek
Due to dependencies between timer and CPU frequency, only changes by powers of two are allowed. The clocksource driver prevents other changes, but with cpufreq and its governors it can result in being spammed with error messages constantly. Hence, remove the 222 MHz OPP.

To silence the warning cpufreq_cpu0: failed to get cpu0 regulator: -19 from the cpufreq driver regarding a missing regulator, add a fixed regulator to the DT. Zynq does not support voltage scaling and the CPU rail should always be supplied with 1 V, hence it is added in the SOC-level dtsi.

2015-07-27Kill unneeded #include <linux/kconfig.h>Masahiro Yamada
Because the top-level Makefile forces all the source files to include include/linux/kconfig.h (see the UBOOTINCLUDE define), these includes are redundant. By the way, there are exceptions for the statement above; host programs. In fact, host tools in U-Boot depend on a particular board configuration, although I think they should not. So, some files still include <linux/config.h> to work around build errors on host tools.

2015-07-27omap-common: SYS_BOOT-based fallback boot device selection for peripheral bootPaul Kocialkowski
OMAP devices might boot from peripheral devices, such as UART or USB. When that happens, the U-Boot SPL tries to boot the next stage (complete U-Boot) from that peripheral device, but in most cases, this is not a valid boot device. This introduces a fallback option that reads the SYS_BOOT pins, that are used by the bootrom to determine which device to boot from. It is intended for the SYS_BOOT value to be interpreted in the memory-preferred scheme, so that the U-Boot SPL can load the next stage from a valid location. Practically, this options allows loading the U-Boot SPL through USB and have it load the next stage according to the memory device selected by SYS_BOOT instead of stalling.
