* lan91c96, smc911x: remove useless free(ptr) calls on NULL ptrSerge Ziryukin2010-05-17-1/+0

* smc911x driver frame alignment patchValentin Yakovenkov2010-05-03-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SMSC911x chips have alignment function to allow frame payload data (which comes after 14-bytes ethernet header) to be aligned at some boundary when reading it from fifo (usually - 4 bytes boundary). This is done by inserting fake zeros bytes BEFORE actual frame data when reading from SMSC's fifo. This function controlled by RX_CFG register. There are bits that represents amount of fake bytes to be inserted. Linux uses alignment of 4 bytes. Ethernet frame header is 14 bytes long, so we need to add 2 fake bytes to get payload data aligned at 4-bytes boundary. Linux driver does this by adding IP_ALIGNMENT constant (defined at skb.h) when calculating fifo data length. All network subsystem of Linux uses this constant too when calculating different offsets. But u-boot does not use any packet data alignment, so we don't need to add anything when calculating fifo data length. Moreover, driver zeros the RX_CFG register just one line up, so chip does not insert any fake data at the beginig. So calculated data length is always bigger by 1 word. It seems that at almost every packet read we get an underflow condition at fifo and possible corruption of data. Especially at continuous transfers, such as tftp. Just after removing this magic addition, I've got tftp transfer speed as it aught to be at 100Mbps. It was really slow before. It seems that fifo underflow occurs only when using byte packing on 32-bit blackfin bus (may be because of very small delay between reads).

* NET: Fix MAC addr handling for smc911xSeunghyeon Rhee2010-01-31-6/+9
| | | | | | | | | | | | | | | | | | | This patch turns off MAC address mismatch warning when optional eeprom programmed with MAC address is not available. In that case, smc911x's MAC address register has its default value ff:ff:ff:ff:ff:ff and it's not a valid address. This makes eth_initialize() show the warning which has no meaningful information while environment variable ethaddr overrides the address read from the register. If there's no eeprom and the value of MAC address register is not valid after initialization, dev->enetaddr had better not be updated and maintain its initial value 00:00:00:00:00:00, which I think is what eth_initialize() expects. This is not a bug fix. Even without this patch, the driver works fine. It's just for enhancing the way of displaying messages.

* Revert "SMC911x driver fixed for NFS boot"Wolfgang Denk2009-06-14-22/+1
| | | | | | | | | | | | This reverts commit ca9c8a1e10fac01e6a1129f82a7ce18bd818fa43, which causes compile warnings ("large integer implicitly truncated to unsigned type") on all systems that use this driver. The warning results from passing long constants (TX_CFG, RX_CFG) into smc911x_set_mac_csr() which is declared to accept "unsigned character" arguments only. Being close to a release, with nobody available to actually test the code or the suggested fixes, it seems better to revert the patch.
* SMC911x driver fixed for NFS bootManikandan Pillai2009-06-08-1/+22
| | | | | | | | | | | | | | eth_halt() function in the smc911x drivers used to call the smc911x_reset() function. eth_halt() used to be called after tftp transfers. This used to put the ethernet chip in reset while the linux boots up resulting in the ethernet driver not coming up. NFS boot used to fail as a result. This patch calls smc911x_shutdown() instead of smc911x_reset(). Some comments received has also been fixed.

| | | | | | | | | | | | | | | | | The environment is the canonical storage location of the mac address, so we're killing off the global data location and moving everything to querying the env directly. Also, do not bother checking the EEPROM if the env is setup. This simplifies the code greatly.

* smc911x: split out useful defines/functions into local headerMike Frysinger2009-02-25-455/+2
| | | | | | | | | | | | | | The smc911x driver has a lot of useful defines/functions which can be used by pieces of code (such as example eeprom programmers). Rather than forcing each place to duplicate these defines/functions, split them out of the smdc911x driver into a local header.

| | | | | | | | | | | | The RSK7203 board has the SMSC9118 wired up 'incorrectly'. Byte-swapping is necessary, and so poor performance is inevitable. This problem cannot evade by the swap function of CHIP, this can evade by software Byte-swapping. And this has problem by FIFO access only. pkt_data_pull/pkt_data_push functions necessary to solve this problem.
