* 86xx: Support 2GB DIMMsBecky Bruce2008-01-10-1/+10
| | | | | | | | Configure the number of bits used to address the banks inside the SDRAM device. The default register value of 0 means 2 bits to address 4 banks. Higher capacity devices like a 2GB DIMM require 3 bits to address 8 banks. Signed-off-by: Becky Bruce <bgill@freescale.com>
* Fix and optimize MII operations on FEC (MPC8xx) controllersGuennadi Liakhovetski2008-01-09-54/+53
| | | | | | | | | | | | | | | | | | | | | | | | This patch fixes several issues at least on a MPC885 based system with two FEC interfaces used in MII mode. 1. PHY discovery should first read PHY_PHYIDR2 register and only then PHY_PHYIDR1 like cpu/mpc8xx/fec.c::mii_discover_phy() does it, otherwise the values read are wrong. Also notice, that PHY discovery cannot work on MPC88x / MPC87x in setups with both FECs active at all in its present form, because for both interfaces the registers from FEC 1 are used to communicate over MII. 2. Remove code duplication for resetting the FEC by isolating it into a separate function. 3. Initialize MII on FEC 1 when communicating over FEC 2 in fec_init(). 4. Optimize mii_init() to only reset the FEC 1 controller once. 5. Fix a typo in mii_init() using index i instead of j thus potentially leading to unpredictable results.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The privious 4xx POST implementation only supported storing the POST WORD in OCM. Since we need to reserve the OCM on LWMON5 for the logbuffer we need to store the POST WORD in some other non volatile location.

This was discovered by GDA using a high bandwidth scope, analyzing the DDR2 signals. GDA provided a fixed value for RQFD, so now on Katmai "only" RFFD is auto-calibrated.

* | | ppc4xx: Add functionality to GPIO supportLawrence R. Johnson2008-01-04-23/+40
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes two additions to GPIO support: First, it adds function gpio_read_in_bit() to read the a bit from the GPIO Input Register (GPIOx_IR) in the same way that function gpio_read_out_bit() reads a bit from the GPIO Output Register (GPIOx_OR). Second, it modifies function gpio_set_chip_configuration() to provide an additional option for configuring the GPIO from the "CFG_4xx_GPIO_TABLE". According to the 440EPx User's Manual, when an alternate output is used, the three-state control is configured in one of two ways, depending on the particular output. The first option is to select the corresponding alternate three-state control in the GPIOx_TRSH/L registers. The second option is to select the GPIO Three-State Control Register (GPIOx_TCR) in the GPIOx_TRSH/L registers, and set the corresponding bit in the GPIOx_TCR register to enable the output. For example, the Manual specifies configuring the GPIO00 Alternate 1 Signal (PreAddr07) to use the alternate three-state control (first option), and specifies configuring the GPIO32 Alternate 1 Signal (USB2OM0) with the output enabled in the GPIOx_TCR register (second option). Currently, gpio_set_chip_configuration() configures all alternate signal outputs to use the first option. This patch allow the second option to be selected by setting the "out_val" element in the table entry to "GPIO_OUT_1". The first option is used when the "out_val" element is set to "GPIO_OUT_0". Because "out_val" is not currently used when an alternate signal is selected, and because all current GPIO tables set "out_val" to "GPIO_OUT_0" for all alternate signals, this patch should not change any existing configurations.
