* net/net.c: Update ipaddr if the environment has changedEnric Balletbo i Serra2011-06-01-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At least on ARM the ipaddr is only set in board_init_r function. The problem is if ipaddr is not defined in environment importing another environment defined don't update the ipaddr value. For example, suppose we've a default environment without net variables defined and we want to import an uEnv.txt environment from SD-card like this: ipaddr=192.168.2.240 netmask=255.255.255.0 gatewayip=192.168.2.1 serverip=192.168.2.114 Then if you try boot from NFS results in: Importing environment from mmc ... Running uenvcmd ... smc911x: detected LAN9221 controller smc911x: phy initialized smc911x: MAC ac:de:48:00:00:00 *** ERROR: `ipaddr' not set The ipaddr at this point is NULL beacause is only set at board_init_r function. This patch updates the ipaddr value if the environment has changed. Signed-off-by: Enric Balletbo i Serra <eballetbo@iseebcn.com> Acked-by: Mike Frysinger <vapier@gentoo.org>

* Create PHY Lib for U-BootAndy Fleming2011-04-20-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extends the mii_dev structure to participate in a full-blown MDIO and PHY driver scheme. The mii_dev structure and miiphy calls are modified in such a way to allow the original mii command and miiphy infrastructure to work as before, but also to support a new set of APIs which allow (among other things) sharing of PHY driver code and 10G support The mii command will continue to support normal PHY management functions (Clause 22 of 802.3), but will not be changed to support 10G (Clause 45). The basic design is similar to PHY Lib from Linux, but simplified for U-Boot's network and driver infrastructure. We now have MDIO drivers and PHY drivers An MDIO driver provides: read write reset A PHY driver provides: (optionally): probe config - initial setup, starting of auto-negotiation startup - waiting for AN, and reading link state shutdown - any cleanup needed The ethernet drivers interact with the PHY Lib using these functions: phy_connect() phy_config() phy_startup() phy_shutdown() Each PHY driver can be configured separately, or all at once using config_phylib_all_drivers.h (added in the patch which adds the drivers) We also provide generic drivers for Clause 22 (10/100/1000), and Clause 45 (10G) PHYs. We also implement phy_reset(), and call it in phy_connect(). Because phy_reset() is essentially the same as miiphy_reset, but: a) must support 10G PHYs, and b) should use the phylib primitives, we implement miiphy_reset, using phy_reset(), but only when CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this way, we save on compile size, even if we don't manage to save code size.

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>

| | | | | | | | | | | | | | | | | | | There are boards out there that do not have network support in U-Boot (CONFIG_CMD_NET not set), but they do so in Linux. This makes it desirable to be able to port network configuration (like the IP address) to the Linux kernel. We should not make the passing of the IP configuration to Linux dependent on U-Boot features / settings. For this, make getenv_IPaddr() global.

* nfs: NfsTimeout() updatesEvan Samanas2009-12-07-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - NfsTimeout() does not correctly update the NFS timeout value which results in NfsTimeout() only being called once in certain situations. This can result in the 'nfs' command hanging indefinetly. For example, the command: nfs 192.168.0.1:/home/user/file will not exit until ctrl-c is pressed if 192.168.0.1 does not have an NFS server running. This issue is resolved by reinitializting the NFS timeout value inside NfsTimeout() when a timeout occurs. - Make the 'nfs' command print the 'T' character when a timeout occurs. Previously there was no indication that timeouts were occuring. - Mimic the 'tftpboot' command and when a download fails print "Retry count exceeded; starting again", and restart the download taking the 'netretry' environment variable into account.
