* Fix Ethernet init() return codesBen Warren2008-01-10-6/+6
| | | | | | | | | | | | | | | | | | Change return values of init() functions in all Ethernet drivers to conform to the following: >=0: Success <0: Failure All drivers going forward should return 0 on success. Current drivers that return 1 on success were left as-is to minimize changes.

* 85xx: add ability to upload QE firmwareTimur Tabi2008-01-09-0/+1
| | | | | | | | | | | Define the layout of a binary blob that contains a QE firmware and instructions on how to upload it. Add function qe_upload_firmware() to parse the blob and perform the actual upload. Add command-line command "qe fw" to take a firmware blob in memory and upload it. Update ft_cpu_setup() on 85xx to create the 'firmware' device tree node if U-Boot has uploaded a firmware. Fully define 'struct rsp' in immap_qe.h to include the actual RISC Special Registers.

* 85xx: Remove cache config from configs.hKumar Gala2008-01-09-2/+7
| | | | | | | | | Either use the standard defines in asm/cache.h or grab the information at runtime from the L1CFG SPR. Also, minor cleanup in cache.h to make the code a bit more readable. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Reworked FSL Book-E TLB macros to be more readableKumar Gala2008-01-09-13/+10
| | | | | | | | | | | The old macros made it difficult to know what WIMGE and perm bits were set for a TLB entry. Actually use the bit masks for these items since they are only a single bit. Also moved the macros into mmu.h out of e500.h since they aren't specific to e500. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* | | 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

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.
