* rtc: ds1307: Fix a memory leakAndrey Smirnov2016-01-071-0/+3
| | | | | | | | | Several failure paths would result in control being transfered to 'exit' label, so instead of just returning error codes in those cases we also need to free the memory allocated for 'ds1307' Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | This fixes a regression, where boards specifying the environment path using the form device-path = &phandle, "partname:part" would be unable to find their env. This is due to of_find_path() switching to cdev_by_device_node() internally, which expects the device_node member of the main area cdev to be initialized.

| | | | | | | | | | | | | | | | | | | | | | | | This patch adds hmac support to the raw backend. With this patch, modifications of the header or data of a state partition can be detected, as the hmac woudln't match anymore. The hmac relies on a shared secret, which is requested from the keystore, with keystore_get_secret() using the name of the state partition as the "name" of the secret.

| * | socfpga: Initialize emac physels to RGMII correctlyTrent Piepho2015-11-111-3/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A comment in the socfpga init said that it was "Clearing emac0 PHY interface select to 0", but this was doubly incorrect. It was setting physel for emac1, not emac0, and it was setting physel to 1 (RGMII) not 0 (GMII). All supported socfpga boards use RGMII, and use emac1, so fix the comment to reflect the code. But then extend the code to set the physel for both emac0 and emac1, so it can work on boards that use either or both emacs (which are called gmac0/1 in the dts). The Cyclone V datasheet, page 17-60 "EMAC HPS Interface Initialization", says to set physel while the EMAC is in reset. So place the EMAC in reset while changing physel. The emacs are not in reset as code earlier in the boot has already taken most of the modules out of reset. So put them back in reset while the physel is changed. The Linux kernel does it this way too. If barebox has no network support, there is not much point in configuring the emac physel lines. This would be the case for the xloader pre-bootloader config, which configures physel, doesn't use the network, loads the main barebox, which then reconfigures physel again. Make this code depend on CONFIG_NET so it's just done in the main barebox. The Linux kernel does not need barebox to do this initialization to use networking.

| * | firmware: socfpga: Add parameter "programmed" to fpgamgr driverTrent Piepho2015-11-111-11/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This boolean parameter tells you if the FPGA is programmed or not. It can be accessed from the shell as "$fpga.programmed". One could use this to not program the FPGA if it's already programmed. There is an annoying limitation of the way barebox puts parameters into the shell env: it requires they have no periods in the device name. It uses the first period to divide the variable name into a device and parameter name, which doesn't work correctly if the device name has a period in it. Since the names of any devices created from the OF device tree have a period in them, this is a problem. So what I did here was create a new device. Its parent will be the OF device for the fpgamgr and it will in turn be the parent of the firmware cdev. Previously the cdev's parent was the OF device. This device won't have period in the name and the parameter is attached to it. Even without the period limitation, doing this gives a nicer name "fpga.programmed" instead of "ff706000.fpgamgr.programmed". The fpgamgr code had a pointer to the OF device in its private state. I changed this to be a struct for the new "fpga" device, which is then used in all the places the former pointer was (nothing but dev_dbg, etc. calls).

This only works because the the FAT code accepts a MBR as input and automatically skips it. Let the code use the partition to mount /boot instead as it was intended. We don't have to stat() the partition device, since this error will be caught by mount() anyway, so remove the unnecessary stat().

This include the clock provided by the PHY. If the PHY is powered down, bit BMCR_PDOWN set, then it won't be generating a clock. And so the MAC never comes out of reset. On shutdown, Linux will put the PHY in powerdown mode, so it can easily be the case that the PHY is powered down on boot. See Linux kernel commit 2d871aa07136fe6e576bde63072cf33e2c664e95. Currently the MAC reset is done before the phy is probed. We can't power up the phy until it's probed, so the resets must be in the opposite order. The MAC reset is in device init but the PHY probe is in device open. Device init is done first, always, while open is done later, and only if the device is used. Rather than move the phy probe to init, this moves the MAC reset to open. It seems better to speed up boots that doesn't use ethernet by skipping MAC reset than to slow them down by adding PHY probe.
