* mpc83xx: Store and display Arbiter Event Register valuesNick Spence2008-09-03-1/+135
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* MPC83XX: Fix GPIO configuration - set gpio level before directionNick Spence2008-09-03-2/+2
| | | | | | | | | | | | | | | | | | | 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.

* fix system config overwrite @ MPC834x and MPC8313Andre Schwarz2008-06-25-0/+5
| | | | | | | | | | | | | | | | During 83xx setup the "System I/O configuration register high" gets overwritten with user defined value if CFG_SICRH is defined. Regarding to the MPC834x manual (Table 5-28 reve.1) bits 28+29 of SICRH must keep their reset value regardless of configuration. On my board (using RGMII) those bits are set after reset - yet it's unclear where they come from. The patch keeps both bits on MPC834x and MPC8313.

* Big white-space cleanup.Wolfgang Denk2008-05-21-1/+1
| | | | | | | | | | | This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>
* mpc8323erdb: Improve the system performanceMichael Barkowski2008-03-25-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following changes are based on kernel UCC ethernet performance: 1. Make the CSB bus pipeline depth as 4, and enable the repeat mode 2. Optimize transactions between QE and CSB. Added CFG_SPCR_OPT switch to enable this setting. The following changes are based on the App Note AN3369 and verified to improve memory latency using LMbench: 3. CS0_CONFIG[AP_n_EN] is changed from 1 to 0 4. CS0_CONFIG[ODT_WR_CONFIG] set to 1. Was a reserved setting previously. 5. TIMING_CFG_1[WRREC] is changed from 3clks to 2clks (based on Twr=15ns, and this was already the setting in DDR_MODE) 6. TIMING_CFG_1[PRETOACT] is changed from 3clks to 2clks. (based on Trp=15ns) 7. TIMING_CFG_1[ACTTOPRE] is changed from 9clks to 6clks. (based on Tras=40ns) 8. TIMING_CFG_1[ACTTORW] is changed from 3clks to 2clks. (based on Trcd=15ns) 9. TIMING_CFG_1[REFREC] changed from 21 clks to 11clks. (based on Trfc=75ns) 10. TIMING_CFG_2[FOUR_ACT] is changed from 10 clks to 7clks. (based on Tfaw=50ns) 11. TIMING_CFG_2[ADD_LAT] and DDR_MODE[AL] changed from 0 to 1 (based on CL=3 and WL=2).

* Update SCCR programming in cpu_init_f() to support all 83xx processorsTimur Tabi2007-08-10-2/+12
| | | | | | | | | | | | | Update the cpu_init_f() function in cpu/mpc83xx/cpu_init.c to program the bitfields for all 83xx processors. The code to update some bitfields was compiled only on some processors. Now, the bitfields are programmed as long as the corresponding CFG_SCCR option is defined in the board header file. This means that the board header file should not define any CFG_SCCR macros for bitfields that don't exist on that processor, otherwise the SCCR will be programmed incorrectly.

* mpc83xx: streamline the 83xx immr head fileDave Liu2007-03-02-4/+4
| | | | | | | | | | | | | | | | For better format and style, I streamlined the 83xx head files, including immap_83xx.h and mpc83xx.h. In the old head files, 1) duplicated macro definition appear in the both files; 2) the structure of QE immr is duplicated in the immap_83xx.h and immap_qe.h; 3) The macro definition put inside the each structure. So, I cleaned up the structure of QE immr from immap_83xx.h, deleted the duplicated stuff and moved the macro definition to mpc83xx.h, Just like MPC8260.
