* 8xxx-fdt: set ns16550 clock from CFG_NS16550_CLK, not bi_busfreqPaul Gortmaker2008-07-14-1/+1
| | | | | | | | | | Some boards that have external 16550 UARTs don't have a direct tie between bi_busfreq and the clock used for the UARTs. Boards that do have such a tie should set CFG_NS16550_CLK to be get_bus_freq(0) -- which most of them do already.

| | | | | | | | Delete the crypto node if not on an E-processor. If on 8360 or 834x family, check rev and up-rev crypto node (to SEC rev. 2.4 property values) if on an 'EA' processor, e.g. MPC8349EA. Signed-off-by: Kim Phillips <kim.phillips@freescale.com>

| * Add mechanisms for CPU and board-specific Ethernet initializationBen Warren2008-07-06-0/+20
| | | | | | | | | | | | | | | | This patch is the first step in cleaning up net/eth.c, by moving Ethernet initialization to CPU or board-specific code. Initial implementation is only on the Freescale TSEC controller, but others will be added soon. Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
* | 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.

| | | | | | | | | | | Change all code that conditionally operates on high bat registers (that is, BATs 4-7) to look at CONFIG_HIGH_BATS instead of the myriad ways this is done now.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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_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>
