* ubimkvol: add support for `volume_id` parameterLeif Middelschulte2018-11-261-3/+7

* FIT: support hash-1/signature-1 nodes in signature checkMatthias Schiffer2018-11-231-2/+6
| | | | | | | | | | | The examples in the U-boot docs use "hash-N" and "signature-N" as the names for hash/signature nodes. It seems "@N" was used instead at some point during the development of the FIT format and "-N" is more correct (in fact, dtc throws warnings when using "@N" without a reg attribute). Support for the "@N" node names is preserved for backward compatibility. Signed-off-by: Matthias Schiffer <matthias.schiffer@ew.tq-group.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* clk: fix NULL deref without OF node in debug messageMatthias Schiffer2018-11-231-1/+1
| | | | | | | | | | | | of_clk_add_provider() may be called for devices added via add_generic_device(). There is no OF node in this case, leading to a crash when debug logs are enabled. This affects various i.MX CPUs, which add imx*-ccm clock devices using add_generic_device().

* mount command: Fix "mount /dev/<devname>"Sascha Hauer2018-11-211-1/+3
| | | | | | | | | | | | | We used to put the device name without the "/dev/" component into device_detect_by_name() and cdev_by_name(). Since 8ca7053b3ff we only put the device name into device_detect_by_name(), but cdev_by_name() still gets the full path. The result is that a "mount /dev/<devname>" no longer works. Fix this.

| | | | | | | | | Upstream dts files changed to the generic binding for mii phys, so we have to support it in barebox aswell. The barebox internal device trees haven't been changed, so support them until all have changed. We print a warning to add some motivation to change.

* nand: denali: remove undefined GFP_DMA flagEnrico Jorns2018-11-191-1/+1
| | | | | | | | | | | | This was a remnant from porting kernel code to barebox. While being uncritical so far, this will now cause a compiler error since kzalloc is not a define but a static inline function. As the kzalloc() 'mode' argument was ignored before and still will be, it is safe to remove the parameter.

* ARM: i.MX: When SRSR shows wdog then lookup reset source in wdogSascha Hauer2018-11-162-8/+8
| | | | | | | | | | | | | On i.MX6 when the watchdog has resetted the system then the SRSR register correctly shows that the watchdog has resetted the system. This is not the desired result though, a "reset" in barebox or "reboot" in Linux should result in "RST" as reset source. So instead of making the SRSR register value overwrite the reset source read from the watchdog registers, interpret the SRSR value corresponding to watchdog reset as "lookup details in the watchdog registers".

* bootm: Print which file cannot be openedSascha Hauer2018-11-151-7/+4
| | | | | | | | | | | When opening the OS image fails we used to print a message *which* file could not be opened. This message is no longer printed since we now fail in read_file_2 when there is an error. Move the message in the read_file_2 failure path to print it again. file_detect_type() needs no handling for ret < 0, in case of failure it returns filetype_unknown which is handled later, so we can remove the error handling there.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Gadget update to 3.15 imported Linux patch e117e742d310 ("usb: gadget: add "maxpacket_limit" field to struct usb_ep"): This patch adds "maxpacket_limit" to struct usb_ep. This field contains maximum value of maxpacket supported by driver, and is set in driver probe. This value should be used by autoconfig() function, because value of field "maxpacket" is set to value from endpoint descriptor when endpoint becomes enabled. So when autoconfig() function will be called again for this endpoint, "maxpacket" value will contain wMaxPacketSize from descriptior instead of maximum packet size for this endpoint. For this reason this patch adds new field "maxpacket_limit" which contains value of maximum packet size (which defines maximum endpoint capabilities). This value is used in ep_matches() function used by autoconfig(). Value of "maxpacket_limit" should be set in UDC driver probe function, using usb_ep_set_maxpacket_limit() function, defined in gadget.h. This function set choosen value to both "maxpacket_limit" and "maxpacket" fields. However said update didn't bring in all driver changes. Do it now.

| | | | | | | | | | | | | | | | | | | | | | | | | | ci_udc_unregister() used to unregister "the controller". Since we may register multiple chipidea devices we called ci_udc_unregister() for each of them. This led to messages like: ERROR: imx-usb 53f80000.usb: gadget not registered.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | An ehci can be registered with ehci_register which is passed a struct device_d *. In that case the priv pointer may already be used by the caller, so we must not use it in the ehci code. At least for the Atmel ehci driver this fixes a bug, here dev->priv is set two times to different values. Since we need dev->priv in the ehci code to get the controller in ehci_detect() we can no longer implement that without the help of the caller, hence we eport ehci_detect() and epect it to be called by the code which registers a ehci host.

| * | of: fix reproducible node name for legacy vs. new partition bindingSascha Hauer2018-10-181-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the of_reproducible_name mechanism is used to find a partition node from the barebox devicetree in the Linux devicetree. Unfortunately we have two different partition bindings. In the legacy one the partition nodes are directly under the hardware devicenode whereas in the new binding the partitions are under an additional partitions subnode. This means we get two different (not so) reproducible names when the barebox devicetree uses the legacy binding and the Linux devicetree uses the new binding (or the other way round). To get the same name then for these cases we drop the partitions subnode from the reproducible name. This makes the partition fixup in barebox-state work when the barebox devicetree uses another binding than the Linux devicetree.
