| * net: phy: Add fixed link supportSascha Hauer2016-05-091-8/+41
| | | | | | | | | | | | | | | | | | | | Some network devices, especially when connected to a switch, are connected via a fixed link. This patch adds support for a fixed phy configured through device tree. TODO: Add support for the "speed" and "full-duplex" properties.

* / string: Fix (v)asprintf prototypesSascha Hauer2016-04-151-1/+1
|/ | | | | | | | | | Our asprintf and vasprintf have different prototypes than the glibc functions. This causes trouble when we want to share barebox code with userspace code. Change the prototypes for (v)asprintf to match the glibc prototypes. Since the current (v)asprintf are convenient to use change the existing functions to b(v)asprintf.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ax_skb receive buffer unalignment leads to consequent unalignment data access in network stack routines, especially in net_checksum(). By-turn unalignment data accesses lead to performance penalty. Moreover on classic MIPS CPUs without hardware unalignment access support this leads to undesirable exceptions. At the moment barebox on MIPS can't parry these unalignment access exceptions, so the Asix USB Ethernet chips, that need receive fixup workaround, are completely unusable on MIPS without this patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dw MAC requires that all clock domains to be running for it to finish a MAC reset. 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.
