| * linux/kernel.h: move ALIGN_DOWN() to include/linux/kernel.hMasahiro Yamada2018-01-052-2/+1
| | | | | | | | | | | | | | | | | | | | Linux commit ed067d4a859f ("linux/kernel.h: Add ALIGN_DOWN macro") moved ALIGN_DOWN to include/linux/kernel.h. Let's do likewise. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | file_list: Add ubi flagSascha Hauer2018-01-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | This flag is added to better support flashing UBI image with Android sparse images. Android fastboot splits images which are bigger than the free memory into multiple images which are then transferred in multiple fastboot sessions. In a session which is not the first one we can no longer detect if an image is a UBI image or not, so we need a flag to make this explicit. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | Add support for fastboot sparse imagesSascha Hauer2018-01-171-0/+67
| | | | | | | | | | | | | | | | This adds support for reading Android fastboot sparse images. This code is based on the corresponding U-Boot code, but has been heavily modified to provide a read-like API which better fits into barebox. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | ubiformat: Add ubiformat write functionSascha Hauer2018-01-111-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | The ubiformat C API expects an image file as argument. With upcoming Android fastboot sparse image support we can no longer provide a complete image anymore. With this patch we can write an image in multiple chunks after we've formatted a MTD device with ubiformat. ubiformat_write will skip the EC header in both the MTD device we write to and also the image we read from, so we can flash an image on a MTD device containing EC headers already.

| * net: Add linuxdevname propertySascha Hauer2017-12-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When you have a static network environment but more than one network device on your machine it is necessary to provide the <device> parameter to the ip parameter at kernel cmd line. The device name assigned by Linux cannot in general be predicted as it depends on driver bind order. This patch introduces a new property linux.devname to eth devices. The value is added to bootargs per interface and can be changed in env/network/INTF Based on patch by Gavin Schenk <g.schenk@eckelmann.de>. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * net: Provide new way to configure network devicesSascha Hauer2017-12-141-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This provides a new way to configure network interfaces based on nvvars. A network interface can now be configured with variables in the nv.dev.<ethname>.* namespace. There is a new network device parameter "mode" which specifies the mode used to obtain IP settings. The mode can be "dhcp", "static" or "disabled": nv.dev.eth0.mode=dhcp (ipaddr, netmask are ignored in this setting) nv.dev.eth0.mode=static nv.dev.eth0.ipaddr=192.168.0.17 nv.dev.eth0.netmask=255.255.0.0 nv.dev.eth0.mode=disabled Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * net: remove "current" network deviceSascha Hauer2017-12-141-2/+0
| | | | | | | | | | | | | | Now that we can do routing we no longer need a "current" network device. Remove it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * net: Pick network device based on IP settingsSascha Hauer2017-12-141-0/+1
| | | | | | | | | | | | | | | | | | The IP/netmask/gateway settings contain all informations needed to pick the correct network device. This patch adds support for that and makes specifying the "current" network interface using the ethact command unnecessary. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * net: dhcp: reworkSascha Hauer2017-12-141-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DHCP code is a mess. It is not clear which options are sent to the server and which options are returned from the server. Also environment variables are read from and written to all over the place. This patch cleans this up. There now is struct dhcp_req_param which is used for options sent to the server and struct dhcp_result which contains the values sent from the server. The values from the server are written to the barebox variables in a single place. Also it's now possible to call the dhcp code without modifying barebox variables at all, storing the result only in the dhcp result struct. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * net: dhcp: Allow to specify network deviceSascha Hauer2017-12-142-4/+6
| | | | | | | | | | | | | | | | | | Instead of allowing to DHCP only on the "current" network device, allow to specify the desired network device. This is a first step to get rid of the concept of a "current" network device. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * net: allow udp connections on specified network deviceSascha Hauer2017-12-011-0/+4
| | | | | | | | | | | | | | | | This allows the DHCP code to configure specific network devices so that DHCP no longer depends on any "current" network device. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * net: Use a single gatewaySascha Hauer2017-12-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There is not much point in having a network device specific gateway. If barebox really is part of such a complicated network in which it needs multiple gateways, then we probably need a real routing table. Until this happens, a single gateway should be enough. This introduces global.net.gateway which holds the gateway ip. The previously used device specific <ethx>.gateway variables still exist, but are only aliases for the single gateway.

| * net: dhcp: Do not overwrite serverip if it is validSascha Hauer2017-12-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Some DHCP servers provide the wrong serverip in which case it is desired to specify it manually and won't let the dhcp command overwrite it. This has previously been done by setting the serverip again to the desired value after dhcp has been executed. With this patch we do not overwrite it in the first place if it is valid already. This is necessary when the serverip is not set via /env/network/eth* but via nv.net.server. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * net: introduce global.net.serverSascha Hauer2017-12-011-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | The server to use is independent of the network device, there is not much point to make the server specific to a network device. This introduces global.net.server as the serverip which is used as standard NFS/tftp server. The previously used eth device specific parameters still exist, but are only aliases for the global single variable. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * net: Add functions to get/set nameserver and domainnameSascha Hauer2017-12-011-0/+4

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calling mdiobus_detect() for a bus that serves as a parent for a MDIO bus multiplexer would result in parent bus being populated with devices that are present on downstream bus that multiplexer happens to be "pointing" at that moment. To avoid that introduce 'is_multiplexed' flag to struct mii_bus and change mdiobus_detect to ignore busses for which that flag is set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To quote corresponding man page: "... Upon successful completion, lseek() returns the resulting offset location as measured in bytes from the beginning of the file." Which for lseek(fd, 0, SEEK_SET) would be 0, so returning 'ret' as final step of the function would mean it'd never return anything but 0 as well. Change the code to explicitly return '1' to fix the problem.
