2009-10-07iwlwifi: incorrect method used for finding valid OTP blocksJay Sternberg
The address stored in the next link address is a word address but when reading the OTP blocks, a byte address is used. Also if the blocks are full and the last link pointer is not zero, then none of the blocks are valid so return an error. The algorithm is simply valid blocks have a next address and that address's contents is zero. Using the wrong address for the next link address gets arbitrary data, obviously. In cases seen, the first block is considered valid when it is not. If the block has in fact been invalidated there may be old data or there may be no data, bad data, or partial data, there is no way of telling. Without this patch it is possible that a device with valid OTP data is unable to work.

2009-08-28iwlwifi: read enhanced tx power info from EEPROM imageWey-Yi Guy
For 6000 series and up, additional enhanced regulatory tx power limitation information is added to EEPROM image. In order to setup the tx power limitation per channel correctly. Read the enhanced tx power information from EEPROM image and update accordingly. The information is provided per SISO (a,b,c) chain based, it also has information for both MIMO2 and MIMO3. For tx power regulatory limitation, take the highest number from all the chains and update. Also update tx_power_user_lmt to the highest power supported by any channels and chains Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

2009-08-20iwlwifi: traverse linklist to find the valid OTP blockWey-Yi Guy
For devices using OTP memory, EEPROM image can start from any one of the OTP blocks. If shadow RAM is disabled, we need to traverse link list to find the last valid block, then start the EEPROM image reading. If OTP is not full, the valid block is the block _before_ the last block on the link list; the last block on the link list is the empty block ready for next OTP refresh/update. If OTP is full, then the last block is the valid block to be used for configure the device.

2009-05-22iwlcore: register locksMohamed Abbas
Add new lock to be used when accessing some registers. Also move the register lock and iwl_grab_nic_access inside the function for register access. This will prevent from forgetting to hold locks and nic access in the right way and make code easier to maintain. We over use the priv->lock spin lock and I guess we need to add new one for Tx queue after that we might need to change most of these lock to BH and just keep priv->lock as irq type.

2009-02-13iwlwifi: fix FAT channel config for 5000 seriesReinette Chatre
The test to find out if we have FAT channels do not consider that the value of regulatory_bands for the 5000 series is larger than its eeprom size. Using the eeprom size is strange in itself. Use a new EEPROM_REGULATORY_BAND_NO_FAT to indicate no FAT support and test for that explicitly.
