* 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).

* PPC: Use r2 instead of r29 as global data pointerWolfgang Denk2008-02-14-1/+1
| | | | | | | | | | | | R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc will refuse to use load/store multiple insns; instead, it issues a list of simple load/store instructions upon function entry and exit, resulting in bigger code size, which in turn makes the build for a few boards fail. Use r2 instead. Signed-off-by: Wolfgang Denk <wd@denx.de>

* Fix linker scripts: add NOLOAD atribute to .bss/.sbss sectionsWolfgang Denk2008-01-12-1/+1
| | | | | | | | | | | | | | | | | | | With recent toolchain versions, some boards would not build because or errors like this one (here for ocotea board when building with ELDK 4.2 beta): ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab] For many boards, the .bss section is big enough that it wraps around at the end of the address space (0xFFFFFFFF), so the problem will not be visible unless you use a 64 bit tool chain for development. On some boards however, changes to the code size (due to different optimizations) we bail out with section overlaps like above. The fix is to add the NOLOAD attribute to the .bss and .sbss sections, telling the linker that .bss does not consume any space in the image. Signed-off-by: Wolfgang Denk <wd@denx.de>

* 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.
