* 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

* ARM1136: Fix cache range checksBenoît Thébaudeau2012-07-21-3/+3
| | | | | | | | | | | | | | bad_cache_range actually returned true if the range was OK, but it was used according to its name, which resulted in all valid dcache range invalidate/flush operations being dropped. Hence, most DMA transfers resulted in garbage data. This patch renames this function according to what it does, and it fixes the interpretation of its return value by other functions. The chosen naming is the same as for ARM926EJ-S in order to be consistent.

| * tegra: add enterrcm commandStephen Warren2012-07-09-0/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tegra's boot ROM supports a mode whereby code may be downloaded and flash programmed over a USB connection. On dev boards, this is typically entered by holding down a "force recovery" button and resetting the CPU. However, not all boards have such a button (one example is the Compulab Trimslice), so a method to enter RCM from software is useful. This change implements the command "enterrcm" to do this, and enables it for all Tegra boards by default. Even on boards other than Trimslice, controlling this over a UART may be useful, e.g. to allow simple remote control without the need for mechanical button actuators, or hooking up relays/... to the button.
