2012-05-23net: Move MAC-seeded rand out of bootp.cJoe Hershberger

2012-05-15net: move bootfile init into eth_initializeMike Frysinger
All arches init this the same way, so move the logic into the core net code to avoid duplicating it everywhere else. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Reviewed-by: Joe Hershberger <joe.hershberger@ni.com>
2012-05-15net: punt bd->bi_ip_addrMike Frysinger
This field gets read in one place (by "bdinfo"), and we can replace that with getenv("ipaddr"). After all, the bi_ip_addr field is kept up-to-date implicitly with the value of the ipaddr env var. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Reviewed-by: Joe Hershberger <joe.hershberger@ni.com>

2012-04-03net/eth.c: fix eth_write_hwaddr() to use dev->enetaddr as fall backEric Miao
Ignore the return value of eth_getenv_enetaddr_by_index(), and if it fails, fall back to use dev->enetaddr, which could be filled up by the ethernet device driver: With the current code, introduced with below commit, eth_write_hwaddr() will fail immediately if there is no eth<n>addr in the environment variables. However, e.g. for an overo based product that uses the SMSC911x ethernet chip (with the MAC address set via EEPROM connected to the SMSC911x chip), the MAC address is still OK. On mx28 boards that are depending on the OCOTP bits to set the MAC address (like the Denx m28 board), the OCOTP bits should be used instead of failing on the environment variables. Actually, this was the original behavior, and was later changed by commit 7616e7850804c7c69e0a22c179dfcba9e8f3f587.

2012-03-18bootstage: Plumb in bootstage calls for basic operationsSimon Glass
This inserts bootstage calls into tftp, usb start and bootm. We could go further, but this is a reasonable start to illustrate the concept. Signed-off-by: Simon Glass <sjg@chromium.org>
2012-03-18bootstage: Replace show_boot_progress/error() with bootstage_...()Simon Glass
These calls should not be made directly any more, since bootstage will call the show_boot_...() functions as needed. Signed-off-by: Simon Glass <sjg@chromium.org>

2012-03-18bootstage: Use show_boot_error() for -ve progress numbersSimon Glass
Rather than the caller negating our progress numbers to indicate an error has occurred, which seems hacky, add a function to indicate this. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Mike Frysinger <vapier@gentoo.org>
2012-03-18net/miiphy/serial: drop duplicate "NAMESIZE" defineMike Frysinger
A few subsystems are using the same define "NAMESIZE". This has been working so far because they define it to the same number. However, I want to change the size of eth_device's NAMESIZE, so rather than tweak the define names, simply drop references to it. Almost no one does, and the handful that do can easily be changed to a sizeof(). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-12-20net: introduce per device indexMichael Walle
Instead of counting the device index everytime a functions needs it, store it in the eth_device struct. eth_register() keeps track of the indices and updates the device's index number. This simplifies some functions in net/eth.c. Additionally, a network driver can now query its index, eg. to get the correct environment ethaddr name.

2011-12-06net: Make sure IPaddr_t is 32 bits in sizeMatthias Weisser
When building u-boot as 64 bit application (e.g. sandbox) ulong might be 64 bits in size. This breaks network code as IPaddr_t is 64 bytes in size then and an IPv4 address is 32 bits in size. This patch makes sure that IPaddr_t is always 32 bits in size. Also some warnings introduced by this patch are fixed.

2011-10-27net: Export auto_load, use it in rarpSimon Glass
The rarp code includes another instance of the auto_load logic, so call what is now net_auto_load() instead.

2011-10-27net: Add more #ifdefs for tftpput to reduce code sizeSimon Glass

2011-10-27net: Hide more code behind CONFIG_CMD_TFTPPUTSimon Glass
This commit reduces code size a little by making the ICMP handler only available to tftpput. This is reasonable since it is the only user at present (ping just uses the normal handler). Signed-off-by: Simon Glass <sjg@chromium.org>

2011-10-26net: tftpput: Rename TFTP to TFTPGETSimon Glass
This is a better name for this protocol. Also remove the typedef to keep checkpatch happy, and move zeroing of NetBootFileXferSize a little earlier since TFTPPUT will need to change this. Signed-off-by: Simon Glass <sjg@chromium.org>
2011-10-26net: tftpput: Add support for receiving ICMP packetsSimon Glass
ICMP packets can tell you when there is no server at the other end. It is useful for tftp to figure this out, so that a quick error can be displayed, rather than pointlessly retrying. This adds an ICMP packet handler to the net interface. Signed-off-by: Simon Glass <sjg@chromium.org>
2011-10-26net: tftpput: Move ICMP code into its own functionSimon Glass

2011-10-23net/dns.c: Fix endian conversion for big-endian in dns commandBernhard Kaindl
net/dns.c used endian conversion macros wrongly (shorts in reply were put swapped into CPU, and then ntohs() was used to swap it back, which broke on big-endian). Fix this by using the correct linux conversion macro for reading a unaligned short in network byte order: get_unaligned_be16() Thanks to Mike Frysinger pointing at the best macro to use.

2011-09-19net/bootp.c: fix tftp load if autoload environment var isn't setPeter Korsgaard
Commit 093498669 (Put common autoload code into auto_load() function) broke handling of autoload environment variable not being set.
