| * sbc8548: Fix up local bus init to be frequency awarePaul Gortmaker2012-01-11-3/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code here was copied from the mpc8548cds support, and it wasn't using the CONFIG_SYS_LBC_LCRR define, and was just unconditionally setting the LCRR_EADC bit. Snooping with a hardware debugger also showed we had LCRR_DBYP set, since we were setting it based on a read of an uninitialized lcrr read via clkdiv. Borrow from the code in the tqm85xx.c support to add LBC frequency aware masking of these bits. This change will correct reliability issues associated with trying to use the 128MB of LBC 100MHz SDRAM on this board. Thanks to Keith Savage for assistance in diagnosing the root cause of this.

| * sbc8548: enable support for hardware SPD errata workaroundPaul Gortmaker2012-01-11-1/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Existing boards by default have an issue where the LBC SDRAM SPD EEPROM and the DDR2 SDRAM SPD EEPROM both land at 0x51. After the hardware modification listed in the README is made, then the DDR2 SPD EEPROM appears at 0x53. So this implements a board specific get_spd() by taking advantage of the existing weak linkage, that 1st tries reading at 0x53 and then if that fails, it falls back to the old 0x51. Since the old dependency issue of "SPD implies no LBC SDRAM" gets removed with the hardware errata fix, remove that restriction in the code, so both LBC SDRAM and SPD can be selected.

| * sbc8548: Make enabling SPD RAM configuration workPaul Gortmaker2012-01-11-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, SPD configuration of RAM was non functional on this board. Now that the root cause is known (an i2c address conflict), there is a simple end-user workaround - remove the old slower local bus 128MB module and then SPD detection on the main DDR2 memory module works fine. We make the enablement of the LBC SDRAM support conditional on being not SPD enabled. We can revisit this dependency as the hardware workaround becomes available. Turning off LBC SDRAM support revealed a couple implict dependencies in the tlb/law code that always expected an LBC SDRAM address. This has been tested with the default 256MB module, a 512MB a 1GB and a 2GB, of varying speeds, and the SPD autoconfiguration worked fine in all cases. The default configuration remains to go with the hard coded DDR config, so the default build will continue to work on boards where people don't bother to read the docs. But the advantage of going to the SPD config is that even the small default module gets configured for CL3 instead of CL4.

| * sbc8548: Fix LBC SDRAM initialization settingsPaul Gortmaker2012-01-11-13/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These were cloned from the mpc8548cds platform which has a different memory layout (1/2 the size). Set the values by comparing to the register file for the board used during JTAG init sequence: LSDMR1 0x2863B727 /* PCHALL */ LSDMR2 0x0863B727 /* NORMAL */ LSDMR3 0x1863B727 /* MRW */ LSDMR4 0x4063B727 /* RFEN */ This differs from what was there already in that the RFEN is not bundled in all four steps implicitly, but issued once as the final step. The other difference seen when comparing vs. the register file init, is that since the memory is split across /CS3 and /CS4, the dummy writes need to go to 0xf000_0000 _and_ to 0xf400_0000. We also rewrite the final LBC SDRAM inits as macros, as there is no real need for them to be a local variable that is modified on the fly at runtime.

| * sbc8548: enable ability to boot from alternate flashPaul Gortmaker2012-01-11-1/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This board has an 8MB soldered on flash, and a 64MB SODIMM flash module. Normally the board boots from the 8MB flash, but the hardware can be configured for booting from the 64MB flash as well by swapping CS0 and CS6. This can be handy for recovery purposes, or for supporting u-boot and VxBoot at the same time. To support this in u-boot, we need to have different BR0/OR0 and BR6/OR6 settings in place for when the board is configured in this way, and a different TEXT_BASE needs to be used due to the larger sector size of the 64MB flash module. We introduce the suffix _8M and _64M for the BR0/BR6 and the OR0/OR6 values so it is clear which is being used to map what specific device. The larger sector size (512k) of the alternate flash needs a larger malloc pool, otherwise you'll get failures when running saveenv, so bump it up accordingly.

| * sbc8548: relocate 64MB user flash to sane boundaryPaul Gortmaker2012-01-11-16/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current situation has the 64MB user flash at an awkward alignment; shifted back from 0xfc00_0000 by 8M, to leave an 8MB hole for the soldered on boot flash @ EOM. But to switch to optionally supporting booting off the 64MB flash, the 64MB will then be mapped at the sane address of 0xfc00_0000. This leads to awkward things when programming the 64MB flash prior to transitioning to it -- i.e. even though the chip spans from 0xfb80_0000 to 0xff7f_ffff, you would have to program a u-boot image into the two sectors from 0xfbf0_0000 --> 0xfbff_ffff so that it was in the right place when JP12/SW2.8 were switched to make the 64MB on /CS0. (i.e. the chip is only looking at the bits in mask 0x3ff_ffff) We also have to have three TLB entries responsible for dealing with mapping the 64MB flash due to this 8MB of misalignment. In the end, there is address space from 0xec00_0000 to 0xefff_ffff where we can map it, and then the transition from booting from one config to the other will be a simple 0xec --> 0xfc mapping. Plus we can toss out a TLB entry. Note that TLB0 is kept at 64MB and not shrunk down to the 8MB boot flash; this means we won't have to change it when the alternate config uses the full 64MB for booting, in TLB0.

| * MPC85xxCDS: Fix missing LCRR_DBYP bits for 66-133MHz LBCPaul Gortmaker2012-01-11-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These boards were meaning to deploy this value: #define LCRR_DBYP 0x80000000 but were missing a zero, and hence toggling a bit that lands in an area marked as reserved in the 8548 reference manual. According to the documentation, LCRR_DBYP should be used as: PLL bypass. This bit should be set when using low bus clock frequencies if the PLL is unable to lock. When in PLL bypass mode, incoming data is captured in the middle of the bus clock cycle. It is recommended that PLL bypass mode be used at frequencies of 83 MHz or less. So the impact would most likely be undefined behaviour for LBC peripherals on boards that were running below 83MHz LBC. Looking at the actual u-boot code, the missing DBYP bit was meant to be deployed as follows: Between 66 and 133, the DLL is enabled with an override workaround. In the future, we'll convert all boards to use the symbolic DBYP constant to avoid these "count the zeros" problems, but for now, just fix the impacted boards.

* | mmc: Change board_mmc_getcd() function prototype.Thierry Reding2012-01-08-34/+29
|/ | | | | | | | | | | | | | | | | | | | | The new API no longer uses the extra cd parameter that was used to store the card presence state. Instead, this information is returned via the function's return value. board_mmc_getcd() returns -1 to indicate that no card-detection mechanism is implemented; 0 indicates that no card is present and 1 is returned if it was detected that a card is present. The rationale for this change can be found in the following email thread: http://lists.denx.de/pipermail/u-boot/2011-November/110180.html In summary, the old API was not consistent with the rest of the MMC API which always passes a struct mmc as the first parameter. Furthermore the cd parameter was used to mean "card absence" in some implementations and "card presence" in others.
