mpc83xx: cleanup System Part and Revision ID Register (SPRIDR) code

2008-03-28T21:01:06+00:00

in the spirit of commit 1ced121600b2060ab2ff9f0fddd9421fd70a0dc6,
85xx's "Update SVR numbers to expand support", simplify SPRIDR processing
and processor ID display.  Add REVID_{MAJ,MIN}OR macros to make
REVID dependent code simpler.  Also added PARTID_NO_E and IS_E_PROCESSOR
convenience macros.

mpc8323erdb: Improve the system performance

2008-03-26T00:16:44+00:00

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).

mpc83xx: Fix the fatal conflict of merge

2008-01-17T17:01:52+00:00

The commit 9e89647889cd4b5ada5b5e7cad6cbe55737a08d7
will cause the mpc8315erdb board can't boot up.

The patch fix that bug, and remove the duplicated #ifdef
CFG_SPCR_TSECEP code and clean the SCCR_TSEC2 for
MPC8313E processor.

mpc83xx: implement board_add_ram_info

2007-08-17T04:12:24+00:00

add board_add_ram_info, to make memory diagnostic output more
consistent. u-boot banner output now looks like:

DRAM:  256 MB (DDR1, 64-bit, ECC on)

and for boards with SDRAM on the local bus, a line such as this is
added:

SDRAM: 64 MB (local bus)

also replaced some magic numbers with their equivalent define names.
