* sdhc_boot: Introduce CONFIG_FSL_FIXED_MMC_LOCATION optionFabio Estevam2012-02-12-0/+8
| | | | | | | | | | | | | | | | | | | Since commit 97039ab98 (env_mmc: Allow board code to override the environment address) mmc_get_env_addr is a weak-aliased function in common/env_mmc.c The mmc_get_env_addr implementation that exists at board/freescale/common/sdhc_boot.c is meant to be used only for PowerPC boards, but currently it is being used for all platforms that have CONFIG_ENV_IS_IN_MMC defined. Introduce CONFIG_FSL_FIXED_MMC_LOCATION so that the boards that need to use the mmc_get_env_addr version from board/freescale/common/sdhc_boot.c could activate this config option on their board file. This fixes the retrieval of CONFIG_ENV_OFFSET on non-PowerPC boards.

| | | | | | | | | | | | | | | | | | | | The Toshiba AC100 (Compal code-name Paz00, aka Dynabook AZ) is a netbook derived from the NVIDIA Tegra Harmony reference board. It ships with Android, but is often repurposed to run Linux. This patch adds just enough support to get a U-Boot serial console, and the ability access built-in eMMC and the external SD slot. v2: * Rebased on latest HEAD, incorporated changes made to other board files. * Moved board files from board/nvidia to board/compal. * Switched to correct odmdata value. This required add the previous patch to fix U-Boot's interpretation of the odmdata RAM size field. * Removed nvmem= from default Linux kernel command-line; no drivers use the reserved memory yet, so there's no point reserving it.

This allows us to get rid of CONFIG_SYS_NAND_ECCSTEPS and CONFIG_SYS_NAND_ECCTOTAL now, which would otherwise be likely to linger unreferenced after a conversion. It also eliminates a temporary error in the hawkboard_nand build, since the spl version of the patch removed ECCSTEPS/TOTAL from hawkboard.h, but the spl conversion is pending (and may be merged via a different tree).

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

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

| | * sbc8548: relocate 64MB user flash to sane boundaryPaul Gortmaker2012-01-11-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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.
