| * tsec: Wait for auto-negotiation to complete without linkPeter Tyser2009-08-21-10/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, waiting for auto-negotiation would only occur if a valid link had been detected. Problems arose when attempting to use a tsec immediately after bootup but before link was achieved, eg: => dhcp Auto-neg error, defaulting to 10BT/HD eTSEC1: No link. Auto-neg error, defaulting to 10BT/HD eTSEC2: No link. => With this patch applied the same operation as above resulted in: => dhcp Waiting for PHY auto negotiation to complete. done Enet starting in 1000BT/FD Speed: 1000, full duplex Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
| * arm: kirkwood: See to it that sent data is 8-byte alignedSimon Kagstrom2009-08-21-4/+18
| | | | | | | | | | | | | | | | | | | | U-boot might use non-8-byte-aligned addresses for sending data, which the kwgbe_send doesn't accept (bootp does this for me). This patch copies the data to be sent to a malloced temporary buffer if it is non-aligned.

| * Wait for the link to come up on kirkwood network initSimon Kagstrom2009-08-21-6/+14
| | | | | | | | | | | | | | | | | | | | This patch makes the device wait for up to 5 seconds for the link to come up, similar to what many of the other network drivers do. This avoids confusing situations where, e.g., a tftp fails when initiated early after U-boot has started (before the link has come up).

| | | | | | | | | | | | Fix bug introduced by 9c048b523413ae5f3ff34e00cf57569c3368ab51. The cfi_flash.c driver cast the flash buffer size to a uchar in flash_write_cfibuffer(). On some flash parts, (tested on Numonyx part PC32F512M29EWH), the buffer size is 1KB. Remove the cast to uchar to enable buffer sizes to be larger.

* UEC FIXED PHY: Determine fixed-phy port using UEC interface name.Richard Retanubun2009-08-10-17/+19
| | | | | | | | | | | Fixed a misunderstanding in the original implementation, 'devnum' that was used in the cpu/ppc4xx/4xx_enet.c implementation was NOT the PHY's SMI address, rather it was the number of the MAC interface on the CPU. The equivalent of this for uec_phy will be the UEC number stored in mii_info->dev->name. Usage example is updated for uec.

The prescalar that converts the function clock to the sampling clock is hardcoded to 0. The reference manual recommends 7 if the function clock is 96MHz. Instead of just changing the hardcoded values, the prescalar is calculated from the value I2C_IP_CLK. The i2c #defines are in kHz. The speed passed into the i2c init routine is in Hz. To be consistent, change the defines to be in Hz. The timing calculations are based on what is done in the linux 2.6.30 kernel in drivers/i2c/buses/i2c_omap.c as apposed to what is done in TRM. The major variables in the timing caculations are specified as #defines that can be overriden as required. The variables and their defaults are I2C_IP_CLK SYSTEM_CLOCK_96 I2C_INTERNAL_SAMPLING_CLK 19200000 I2C_FASTSPEED_SCLL_TRIM 6 I2C_FASTSPEED_SCLH_TRIM 6 I2C_HIGHSPEED_PHASE_ONE_SCLL_TRIM I2C_FASTSPEED_SCLL_TRIM I2C_HIGHSPEED_PHASE_ONE_SCLH_TRIM I2C_FASTSPEED_SCLH_TRIM I2C_HIGHSPEED_PHASE_TWO_SCLL_TRIM I2C_FASTSPEED_SCLL_TRIM I2C_HIGHSPEED_PHASE_TWO_SCLH I2C_FASTSPEED_SCLH_TRIM This was runtime verified on Zoom1, Zoom2, Beagle and Overo.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a compilation warning for some Ethernet PHY-less PPC4xx platforms (440SPE based ones) and a potential compilation error for 440SP platforms (use of undefined 'ethgroup' variable). In the original code and in case of 440SPE platforms, 'ethgroup' is initialized to -1 and never modified. Later in the function, within an #ifdef statement, an 'if statement' executes code only if 'ethgroup' is set to 4, therefore it is harmless to avoid executing the 'if statement' by removing the CONFIG_440SPE from the affected #ifdefs. In case of 440SP platforms with on-board Ethernet PHY, 'ethgroup' is undefined but used (there are not such platforms in the repository yet). All other architectures are not affected by this change.

* | arm: Kirkwood: Fix compiler optimization bug for kwgbe_sendSimon Kagstrom2009-07-22-12/+19
| | | | | | | | | | | | | | | | | | | | | | kwgbe_send/recv both have loops waiting for the hardware to set a bit. GCC 4.3.3 cleverly optimizes the send case to ... a while(1); loop. This patch uses readl to force a read from device memory. Other volatile accesses have also been replaced with readl/writel where appropriate (as per suggestions on the U-boot mailing list).
