2015-08-28image: Fix loop condition to avoid warningThierry Reding
GCC 5.1 starts warning for comparisons such as !a > 0, assuming that the negation was meant to apply to the whole expression rather than just the left operand. Indeed the comparison in the FIT loadable code is confusingly written, though it does end up doing the right thing. Rewrite the condition to be more explicit, that is, iterate over strings until they're exhausted.

2015-08-26x86: crownbay: Support Topcliff integrated pci uart devices with driver modelBin Meng
In order to make a pci uart device node to be properly bound to its driver, we need make sure its parent node has a compatible string which matches a driver that scans all of its child device nodes in the device tree. Change all pci bridge nodes under root pci node to use "pci-bridge" compatible driver, as well as corresponding <reg> properties to indicate its devfn. At last, adding "u-boot,dm-pre-reloc" to each of these nodes for driver model to initialize them before relocation.

2015-08-26dm: core: Fix code reentrancy issue in device_probe_child()Bin Meng
The device might have already been probed during the call to device_probe() on its parent device (e.g. PCI bridge devices). In its parent device's probe routine, it might probe all of its child devices via device_probe() thus the codes reenter device_probe_child(). To support code reentrancy, test these allocated memory against NULL to avoid memory leak, and return to the caller if dev->flags has DM_FLAG_ACTIVATED set after device_probe() returns, so that we don't mess up the device.

2015-08-26x86: crownbay: Enable on-board SMSC superio keyboard controllerBin Meng
So far we only enabled one legacy serial port on the SMSC LPC47m superio chipset on Intel Crown Bay board. As the board also has dual PS/2 ports routed out, enable the keyboard controller which is i8042 compatible so that we can use PS/2 keyboard and mouse. In order to make PS/2 keyboard work with the VGA console, remove CONFIG_VGA_AS_SINGLE_DEVICE. To boot Linux kernel with PIC mode using PIRQ routing table, adjust the mask in the device tree to reserve irq12 which is used by PS/2 mouse.

2015-08-26video: cfb_console: Allow VGA device to work without i8042 keyboardBin Meng
So far if CONFIG_VGA_AS_SINGLE_DEVICE is not defined, the VGA device will try to initialize a keyboard device (for x86, it is i8042). But if i8042 controller initialization fails (eg: there is no keyboard connected to the PS/2 port), drv_video_init() just simply returns. This kills the opportunity of using a usb keyboard later with the vga console, as the vga initialization part is actually ok, only keyboard part fails. Change the code logic to allow this.

2015-08-26x86: i8042: Correctly initialize the controllerBin Meng
The existing i8042 keyboard controller driver has some issues. First of all, it does not issue a self-test command (0xaa) to the controller at the very beginning. Without this, the controller does not respond to any command at all. Secondly, it initializes the configuration byte register to turn on the keyboard's interrupt, as U-Boot does not normally allow interrupts to be processed. Finally, at the end of the initialization routine, it wrongly sets the controller to disable all interfaces including both keyboard and mouse.

2015-08-26x86: fsp: Call fsp_init_phase_pci() in pci_uclass_post_probe()Bin Meng
Per Intel FSP specification, we should call FSP notify API to inform FSP that PCI enumeration has been done so that FSP will do any necessary initialization as required by the chipset's BIOS Writer's Guide (BWG). Unfortunately we have to put this call here as with driver model, the enumeration is all done on a lazy basis as needed, so until something is touched on PCI it won't happen. Note we only call this after U-Boot is relocated and root bus has finished probing. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>

2015-08-26x86: ifdtool: Drop microcode from the device tree when collatingSimon Glass
When ifdtool collates the microcode into one place it effectively creates a copy of the 'data' properties in the device tree microcode nodes. This is wasteful since we now have two copies of the microcode in the ROM. To avoid this, remove the microcode data from the device tree and shrink it down. This means that there is only one copy and the overall ROM space used by the microcode does not increase.

2015-08-26x86: ifdtool: Support collating microcode into one placeSimon Glass
The Intel Firmware Support Package (FSP) requires that microcode be provided very early before the device tree can be scanned. We already support adding a pointer to the microcode data in a place where early init code can access. However this just points into the device tree and can only point to a single lot of microcode. For boards which may have different CPU types we must support multiple microcodes and pass all of them to the FSP in one place. Enhance ifdtool to scan all the microcode, place it together in the ROM and update the microcode pointer to point there. This allows us to pass multiple microcode blocks to the FSP using its existing API. Enable the flag in the Makefile so that this feature is used by default for all boards.
