* am33xx: Remove board/ti/am335x/evm.cTom Rini2012-09-01-0/+173
| | | | | | | | | The intention has always been (and boards are to support) an i2c EEPROM that will identify what hardware they are, allowing a single binary to support multiple boards. As such, remove the 'evm.c' file as there is nothing EVM centric in it currently, only SoC peripheral configuration. Signed-off-by: Tom Rini <trini@ti.com>
* am33xx: Add DDR3 (Micron MT41J128M16JT-125) timings and supportTom Rini2012-09-01-0/+60

* am33xx: Rework config_ddr to make DDR3 support easier.Tom Rini2012-09-01-14/+23
| | | | | | | | In order to support DDR3 as well as DDR2, we need to perform the same init sequence, but with different values. So change config_ddr() to toggle setting pointers/etc for what DDR2 wants, and then calling. Signed-off-by: Tom Rini <trini@ti.com>
* am33xx: Move some variables in emif4.c, mark them static.Tom Rini2012-09-01-4/+3
| | | | | | We need vtpreg and ddrctrl but no longer need a second ddrregs. Signed-off-by: Tom Rini <trini@ti.com>
* am33xx: Correct and clean up ddr_regs structTom Rini2012-09-01-34/+20
| | | | | | | | | | | | | | The ddr_regs struct was incorrectly offset after the dt0wiratio0 entry. Correct this by documenting a missing register that will be used at some point in the future (when write leveling is supported). Further, the cmdNcs{force,delay} fields are undocumented and we have been setting them to zero, remove. Next, setting of the 'DATAn_REG_PHY_USE_RANK0_DELAYS field belongs with the rest of the ddr_data entries, so program it there. Finally, comment on how we are configuring the DATA1 registers that correspond to the DATA0 (dt0) registers defined in the struct. Signed-off-by: Tom Rini <trini@ti.com>
* am33xx: Do not touch 'ratio1' fieldsTom Rini2012-09-01-35/+7
| | | | | | | | | The various ratio1 fields are not documented in any of the documentation I can find. Removing these and testing has yielded success, so remove the code that sets them and move their locations into the reserved fields. Signed-off-by: Tom Rini <trini@ti.com>
* am33xx: Rework config_io_ctrl slightlyTom Rini2012-09-01-27/+8
| | | | | | | | | This function sets a number of related registers to the same value (the registers in question all have the same field descriptions and are related in operation). Rather than defining a struct and setting the value repeatedly, just pass in the value. Signed-off-by: Tom Rini <trini@ti.com>
* am33xx: Use emif_regs struct for storing initialization valuesTom Rini2012-09-01-78/+31
| | | | | | | Rather than defining our own structs to note what to use when programming the EMIF and related re-use the emif_regs struct. Signed-off-by: Tom Rini <trini@ti.com>
* am33xx: Turn a number of 'int' functions to 'void'Tom Rini2012-09-01-42/+15
| | | | | | | | A number of memory initalization functions were int and always returned 0. Further it's not feasible to be doing error checking here, so simply turn them into void functions. Signed-off-by: Tom Rini <trini@ti.com>
* am33xx: Document what we're doing with ddrctrl->ddrckectrlTom Rini2012-09-01-4/+3
| | | | | | | | | - Remove the call to set ddrctrl->ddrioctrl as it's all zeros. - Comment what we're really setting in ddrctrl->ddrckectrl which is that we're operating in the normal mode where EMIF/PHY clock is controlled by the PHY. Signed-off-by: Tom Rini <trini@ti.com>
* am335x: ddr_defs: Update EMIF parametersVaibhav Bedia2012-09-01-5/+5
| | | | | | | | | | | | | | | | | EMIF parameters are calculated based on the AC timing parameters from the SDRAM datasheet and the DDR frequency. Current values for these paramters in AM335x U-Boot code, though reliable, are not fully optimal. The most optimal settings can be derived based on the guidelines published at [1]. A pre-computed set of values with the most optimum settings for AM335x EVM and BeagleBone can be found at [2].

* am33xx: Clean up unused DDR defines, prefix more with 'DDR2'Tom Rini2012-09-01-43/+35
| | | | | | | - Remove a handful of unused defines. - Prefix more values with 'DDR2' as DDR3 will require different values. Signed-off-by: Tom Rini <trini@ti.com>
* am33xx: Move the call to ddr_pll_config, make it take the frequencyTom Rini2012-09-01-3/+5
| | | | | | | | Depending on if we have DDR2 or DDR3 on the board we will need to call ddr_pll_config with a different value. This call can be delayed slightly to the point where we know which type of memory we have. Signed-off-by: Tom Rini <trini@ti.com>
* am33xx: Pass to config_ddr the type of memory that is connectedTom Rini2012-09-01-20/+31
| | | | | | | | | We need to pass in the type of memory that is connected to the board. The only reliable way to do this is to know what type of board we are running on (which later will be knowable in s_init()). For now, pass in the value of DDR2. Signed-off-by: Tom Rini <trini@ti.com>
* am33xx: Make config_cmd_ctrl / config_ddr_data take const structsTom Rini2012-09-01-61/+48
| | | | | | | | | Rework the EMIF4/DDR code slightly to setup the structs that config_cmd_ctrl and config_ddr_data take to be setup at compile time and mark them as const. This lets us simplify the calling path slightly as well as making it easier to deal with DDR3. Signed-off-by: Tom Rini <trini@ti.com>
* am33xx: Rework DDR2 EMIF initalization slightlyTom Rini2012-09-01-15/+2
| | | | | | | With the previous bugfix we now don't need to set two different REF_CTRL values and instead set the final value. Signed-off-by: Tom Rini <trini@ti.com>
* am33xx: Bugfix to config_sdram()Tom Rini2012-09-01-2/+1
| | | | | | | When we change SDRAM_CONFIG this triggers a refresh based on all of the parameters that we have programmed so we must do this last. Signed-off-by: Tom Rini <trini@ti.com>
* am33xx: Remove extra check in enable_ddr_clocksTom Rini2012-09-01-5/+0

| | | | | | | | | | | | | | | DA850/OMAP-L138 does not support strict MMC/SD boot mode. SPL will be in SPI flash and U-Boot image will be in MMC/SD card. SPL will do the low level initialization and then loads the u-boot image from MMC/SD card. Define CONFIG_SPL_MMC_LOAD macro in the DA850/OMAP-L138 configuration file to enable this feature.
