x86: efi: Fix EFI 64-bit payload build warnings

2016-08-30T01:26:05+00:00

There are lots of warnings when building EFI 64-bit payload.

include/asm-generic/bitops/__fls.h:17:2:
  warning: left shift count >= width of type
  	if (!(word & (~0ul << 32))) {
			^

In fact, U-Boot itself as EFI payload is running in 32-bit mode.
So BITS_PER_LONG needs to still be 32, but EFI status codes are
64-bit when booting from 64-bit EFI. Introduce EFI_BITS_PER_LONG
to bridge those status codes with U-Boot's BITS_PER_LONG.

i2c: intel_i2c: SMBus driver PCI addition (e.g. BayTrail)

2016-08-16T03:44:09+00:00

This patch adds support for the SMBus block read/write functionality.
Other protocols like the SMBus quick command need to get added
if this is needed.

This patch also removed the SMBus related defines from the Ivybridge
pch.h header. As they are integrated in this driver and should be
used from here. This change is added in this patch to avoid compile
breakage to keep the source git bisectable.

Tested on a congatec BayTrail board to configure the SMSC2513 USB
hub.

x86: cache.h: Add default for CONFIG_SYS_CACHELINE_SIZE

2016-08-16T03:44:09+00:00

Don't just define ARCH_DMA_MINALIGN but also CONFIG_SYS_CACHELINE_SIZE
if it's undefined. This is needed for the xhci driver to compile.

x86: baytrail: acpi: Hide internal UART per GNVS setting

2016-07-12T05:46:01+00:00

If global NVS says internal UART is not enabled, hide it in the ASL
code so that OS won't see it.

There is a device.h for quark on-chip devices, mainly for definitions

x86: acpi: Make irqroute.asl common

2016-05-30T02:21:12+00:00

The irqroute.asl file is already common enough to all x86 platforms.
Platform ASL files need only provide a irqroute.h to describe how
internal PCI devices and PCIe downstream port devices' INTx pins are
routed to which PIRQ pin.
