2014-11-23pci: Honour pci_skip_dev()Thierry Reding
When enumerating devices, honour the pci_skip_dev() function. This can be used by PCI controller drivers to restrict which devices will be probed. This is required by the NVIDIA Tegra PCIe controller driver, which will fail with a data abort exception if an access is attempted to a device number larger than 0 outside of bus 0. pci_skip_dev() is therefore implemented to prevent any such accesses.

2014-11-23pci: Abort early if bus does not existThierry Reding
When listing the devices on a PCI bus, the current code will blindly try to access all devices. Internally this causes pci_bus_to_hose() to be repeatedly called and output an error message every time. Prevent this by calling pci_bus_to_hose() once and abort early if no bus was found.

2014-11-23fs: make it possible to read the filesystem UUIDChristian Gmeiner
Some filesystems have a UUID stored in its superblock. To allow using root=UUID=... for the kernel command line we need a way to read-out the filesystem UUID. changes rfc -> v1: - make the environment variable an option parameter. If not given, the UUID is printed out. If given, it is stored in the env variable. - corrected typos - return error codes changes v1 -> v2: - fix return code of do_fs_uuid(..) - document do_fs_uuid(..) - implement fs_uuid_unsuported(..) be more consistent with the way other optional functionality works changes v2 -> v3: - change ext4fs_uuid(..) to make use of #if .. #else .. #endif construct to get rid of unreachable code Hit any key to stop autoboot: 0 => fsuuid fsuuid - Look up a filesystem UUID Usage: fsuuid <interface> <dev>:<part> - print filesystem UUID fsuuid <interface> <dev>:<part> <varname> - set environment variable to filesystem UUID => fsuuid mmc 0:1 d9f9fc05-45ae-4a36-a616-fccce0e4f887 => fsuuid mmc 0:2 eb3db83c-7b28-499f-95ce-9e0bb21cda81 => fsuuid mmc 0:1 uuid1 => fsuuid mmc 0:2 uuid2 => printenv uuid1 uuid1=d9f9fc05-45ae-4a36-a616-fccce0e4f887 => printenv uuid2 uuid2=eb3db83c-7b28-499f-95ce-9e0bb21cda81 => Signed-off-by: Christian Gmeiner <christian.gmeiner@gmail.com> Acked-by: Stephen Warren <swarren@nvidia.com>
2014-11-23spl: Change debug to printf for "Unsupported boot-device"Stefan Roese
We had the problem on an AM33xx platform, that SPL detected an unsupported boot-device. But since this message is a debug message it took a bit of time to really know, where the hangup in SPL resulted from. So let's change this debug message to a printf and also print the detected boot-device that is not supported. This makes debugging of such cases much easier.

2014-11-23linux/kernel.h: sync min, max, min3, max3 macros with LinuxMasahiro Yamada
U-Boot has never cared about the type when we get max/min of two values, but Linux Kernel does. This commit gets min, max, min3, max3 macros synced with the kernel introducing type checks. Many of references of those macros must be fixed to suppress warnings. We have two options: - Use min, max, min3, max3 only when the arguments have the same type (or add casts to the arguments) - Use min_t/max_t instead with the appropriate type for the first argument Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Pavel Machek <pavel@denx.de> Acked-by: Lukasz Majewski <l.majewski@samsung.com> Tested-by: Lukasz Majewski <l.majewski@samsung.com> [trini: Fixup arch/blackfin/lib/string.c] Signed-off-by: Tom Rini <trini@ti.com>

2014-11-21dm: spl: Make simple malloc() available when enabledSimon Glass
Set up the simple malloc() implementation when requested, in preference to the full malloc(). Signed-off-by: Simon Glass <sjg@chromium.org>
2014-11-21dm: Split the simple malloc() implementation into its own fileSimon Glass
The simple malloc() implementation is used when memory is tight. It provides a simple buffer with an incrementing pointer. At present the implementation is inside dlmalloc. Move it into its own file so that it is easier to find. Rather than using relocation as a signal that the full malloc() is available, add a special GD_FLG_FULL_MALLOC_INIT flag. This signals that the simple malloc() should no longer be used. In some cases, such as SPL, even the code space used by the full malloc() is wasteful. Add a CONFIG_SYS_MALLOC_SIMPLE option to provide only the simple malloc. In this case the full malloc is not available at all. It saves about 1KB of code space and about 0.5KB of data on Thumb 2.

2014-11-04usb: kbd: Add (optional) support for using an interrupt queue for pollingHans de Goede
Waiting an interrupt packet to complete in usb_kbd_poll_for_event, causes a 40 ms latency for each call to usb_kbd_testc, which is undesirable. Using control messages leads to lower (but still not 0) latency, but some devices do not work well with control messages (e.g. my kvm behaves funny with them). This commit adds support for using the int_queue mechanism which at least the ehci-hcd driver supports. This allows polling with 0 latency, while using interrupt packets.
