* ARMV7: Add support For Logic OMAP35x/DM37x modulesPeter Barada2012-01-16-0/+703
| | | | | | | | | | | | This patch adds basic support for OMAP35x/DM37x SOM LV/Torpedo reference boards. It assumes U-boot is loaded to SDRAM with the help of another small bootloader (x-load) running from SRAM.

| | | | | | | | | | | This patch removes the defines CONFIG_SYS_ICACHE_OFF, CONFIG_SYS_DCACHE_OFF, and CONFIG_SYS_L2CACHE_OFF from the board configuration.

* arm, davinci: Use a common configuration file for da850evm and da850_am18xxevmChristian Riesch2012-01-16-247/+1
| | | | | | | | | | | | | | | | In commit 06194b6b65f701a9d6ef2d9b4123c4afe57d8783 a separate header file was introduced for the AM1808 EVM, include/configs/da850_am18xxevm.h. Before this commit, the da850evm.h configuration file was used for both the AM1808 and the OMAP-L138 EVMs. The only substantial difference between the da850evm and the da850_am18xxevm configuration is a single bit in the hardware revision that is passed to the Linux kernel. This patch removes include/configs/da850_am18xxevm.h. Instead the include/configs/da850evm.h configuration is used for AM18xx EVMs and CONFIG_DA850_AM18X_EVM is defined in boards.cfg.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Gortmaker2012-01-11-7/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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.

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.

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.

The commit "SBC8548: fix address mask to allow 64M flash" essentially made this change: * OR6: - * Addr Mask = 64M = OR6[0:16] = 1111 1100 0000 0000 0 + * Addr Mask = 64M = OR6[0:16] = 1111 1000 0000 0000 0 But this makes no sense, as section 13.3.1.2.1 in the MPC8548ERM v2 clearly indicates the masks: 1111_1111_1000_0000_0 8 Mbytes 1111_1100_0000_0000_0 64 Mbytes 1111_1000_0000_0000_0 128 Mbytes So the original value was correct, and the commit was invalid, causing a 128MB mapping for a 64MB flash device. The problem rears its head when trying to configure u-boot to have access to both flash, since the default memory map is: FB80_0000 – FF7F_FFFF 32-bits 64MB FLASH SODIMM FF80_0000 – FFFF_FFFF 8-bits 8MB FLASH By extending the mapping of the 64MB flash to 128MB, it now conflicts with the normal 8MB boot flash, causing issues.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | * eXMeritus HWW-1U-1A: Add support for the AT24C128N I2C EEPROMKyle Moffett2012-01-11-2/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This EEPROM is hardware-write-protected and used to persist key information such as the serial number and MAC addresses even if the primary environment sector in NOR FLASH is overwritten. During manufacturing, the environment is initialized from Linux and then the key parameters copied to the EEPROM via U-Boot: env export -c -s 0x2000 $loadaddr serial# macaddr mac1addr mac2addr eeprom write $loadaddr 0x0000 0x2000 The chip is then locked via hardware for delivery. When doing a field U-Boot upgrade, the environment is erased and reset to the defaults to avoid problems with "hwconfig" changes, etc. After loading the new U-Boot image, the hardware data is reloaded: i2c dev 0 eeprom read $loadaddr 0x0000 0x2000 env import -c $loadaddr 0x2000 saveenv The first three commands are saved in the "restore_eeprom" variable for user convenience. (EG: "run restore_eeprom && saveenv") Signed-off-by: Kyle Moffett <Kyle.D.Moffett@boeing.com> Cc: Andy Fleming <afleming@gmail.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
| | * eXMeritus HWW-1U-1A: Minor environment variable tweaksKyle Moffett2012-01-11-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the ethernet connections are internal links with specialized hardware and are not useful for "dhcp" or general-purpose networking; U-Boot should not be cycling through them. Force the primary external network interface in "ethprime" and disable the interface cycling with "ethrotate=no". Additionally, the environment variable "preboot" has its own config option and means something entirely different from what the HWW-1U-1A variable was intended for. Rename the board variable to "setbootargs" to avoid potential confusion. Finally, fix an incorrect address for the kernel in FLASH memory.
