* 83xx: Use the proper sequence for updating IMMR.Scott Wood2009-01-21-3/+15
| | | | | | | | | | | This ensures that subsequent accesses properly hit the new window. The dcbi during the NAND loop was accidentally working around this; it's no longer necessary, as the cache is not enabled.

* mpc83xx: Add support for MPC83xx PCI-E controllersAnton Vorontsov2009-01-21-2/+317
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for MPC83xx PCI-E controllers in Root Complex mode. The patch is based on Tony Li and Dave Liu work[1]. Though unlike the original patch, by default we don't register PCI-E buses for use in U-Boot, we only configure the controllers for future use in other OSes (Linux). This is done because we don't have enough of spare BATs to map all the PCI-E regions. To actually use PCI-E in U-Boot, users should explicitly define CONFIG_83XX_GENERIC_PCIE_REGISTER_HOSES symbol in the board file. And only then U-Boot will able to access PCI-E, but at the cost of disabled address translation.

* 83xx: PCI agent mode fixes for multi-board systemsIra Snyder2009-01-21-0/+5
| | | | | | | | | | | | | | | | | | When running a system with 2 or more MPC8349EMDS boards in PCI agent mode, the boards will lock up the PCI bus by scanning against each other. The boards lock against each other by trying to access the PCI bus before clearing their configuration lock bit. Both boards end up in a loop, sending and receiving "Target Not Ready" messages forever. When running in PCI agent mode, the scanning now takes place after the boards have cleared their configuration lock bit. Also, add a missing declaration to the mpc83xx.h header file, fixing a build warning. Signed-off-by: Ira W. Snyder <iws@ovro.caltech.edu> Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
* mpc83xx: Size optimization of start.SRon Madrid2009-01-21-38/+39
| | | | | | | | | | | Currently there are in excess of 100 bytes located at the beginning of the image built by start.S that are not being utilized. This patch moves a few functions into this part of the image. This will create a greater number of *available* bytes that can be used by board specific code in NAND builds and will decrease the size of the assembled code in other builds.

| * mpc83xx: Store and display Arbiter Event Register valuesNick Spence2008-09-03-1/+146
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Record the Arbiter Event Register values and optionally display them. The Arbiter Event Register can record the type and effective address of an arbiter error, even through an HRESET. This patch stores the values in the global data structure. Display of the Arbiter Event registers immediately after the RSR value can be enabled with defines. The Arbiter values will only be displayed if an arbiter event has occured since the last Power On Reset, and either of the following defines exist: #define CONFIG_DISPLAY_AER_BRIEF - display only the arbiter address and and type register values #define CONFIG_DISPLAY_AER_FULL - display and interpret the arbiter event register values Address Only transactions are one of the trapped events that can register as an arbiter event. They occur with some cache manipulation instructions if the HID0_ABE (Address Broadcast Enable) is set and the memory region has the MEMORY_COHERENCE WIMG bit set. Setting: #define CONFIG_MASK_AER_AO - prevents the arbiter from recording address only events, so that it can still capture other real problems.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Set DAT value before DIR values to avoid creating glitches on the GPIO signals. Set gpio level register before direction register to inhibit glitches on high level output pins. Dir and data gets cleared at powerup, so high level output lines see a short low pulse between setting the direction and level registers. Issue was seen on a new board with the nReset line of the NOR flash connected to a GPIO. Setting the direction register puts the NOR flash in reset so the next instruction to set the level cannot get executed.

* | Pass in tsec_info struct through tsec_initializeAndy Fleming2008-09-02-13/+7
|/ | | | | | | | | | | | | The tsec driver contains a hard-coded array of configuration information for the tsec ethernet controllers. We create a default function that works for most tsecs, and allow that to be overridden by board code. It creates an array of tsec_info structures, which are then parsed by the corresponding driver instance to determine configuration. Also, add regs, miiregs, and devname fields to the tsec_info structure, so that we don't need the kludgy "index" parameter.
