*-. Merge samsung, imx, tegra into u-boot-arm/masterAlbert ARIBAUD2012-12-22-220/+129
|\ \ | | | | | | | | | | | | | | | This commit merges branches from samsung, imx and tegra meant to fix merge issues between u-boot/master and u-boot-arm/master, as well as a few manual merge fixes.
| | * mxs: i2c: Implement algorithm to set up arbitrary i2c speedMarek Vasut2012-12-11-0/+2
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | This algorithm computes the values of TIMING{0,1,2} registers for the MX28 I2C block. This algorithm was derived by using a scope, but the result seems correct. The resulting values programmed into the registers do not correlate with the contents in datasheet. When using the values from the datasheet, the I2C clock were completely wrong.

| * mxs: SPL: Generalize memory initializationOtavio Salvador2012-12-07-6/+13
| | | | | | | | | | | | | | | | Use a generic 'dram_vals[]' array that has the full initialization sequence and rename the initialization method so it doesn't has a frequency on its name. Signed-off-by: Otavio Salvador <otavio@ossystems.com.br>
| * mxs: Staticize SPL functionsMarek Vasut2012-12-04-34/+34
| | | | | | | | | | | | | | | | | | The MXS SPL didn't mark local functions "static". Fix it. This also makes the SPL smaller by roughly 300 bytes. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Stefano Babic <sbabic@denx.de> Cc: Fabio Estevam <fabio.estevam@freescale.com>
| * mxs: Properly setup VDDD in power supply setup codeMarek Vasut2012-12-04-14/+1
| | | | | | | | | | | | | | | | | | The memory setup code adjusted the VDDD voltage. Remove this adjustment and configure the VDDD voltage correctly in the power supply setup code.

| * mxs: Implement common function to setup VDDxMarek Vasut2012-12-04-170/+83
|/ | | | | | | | | | | | | | Implement common function to setup the VDDIO, VDDD and VDDA voltage. Right now, there are two almost identical functions to setup VDDIO and VDDD, which is prone to breakage. Pull out the differences into constant structure and pass them as an argument to the common function. Moreover, the function has almost identical loops for setting higher and lower VDDx voltage. Merge these two loops. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Stefano Babic <sbabic@denx.de> Cc: Fabio Estevam <fabio.estevam@freescale.com>
* common: Discard the __u_boot_cmd sectionMarek Vasut2012-10-22-3/+0
| | | | | | | | | | | The command declaration now uses the new LG-array method to generate list of commands. Thus the __u_boot_cmd section is now superseded and redundant and therefore can be removed. Also, remove externed symbols associated with this section from include/command.h .

* common: Add .u_boot_list into all linker filesMarek Vasut2012-10-22-0/+4
| | | | | | | | | | Add section for the linker-generated lists into all possible linker files, so that everyone can easily use these lists. This is mostly a mechanical adjustment.

* serial: mxs: spl: Remove empty serial_* functions from SPL codeMarek Vasut2012-10-15-4/+0
| | | | | | | | | | | | Remove the empty bodies from serial_* functions from MXS SPL code. These empty implementations are now in common/serial.c instead so declaring them also in the SPL code would cause a colision once serial multi is enabled unconditionally.

* mxs: Convert timeout parameter to 'unsigned int'fabio.estevam@freescale.com2012-09-01-2/+4

| | | | | | | | | | | | | | | | The DRAM initialization, after SPL has complete, is exactly the same for all mxs SoCs so we should name it accordinly.

* mxs: Only build internal Ethernet controller for i.MX28Otavio Salvador2012-09-01-1/+1
| | | | | | | | | The internal Ethernet controller is only available on i.MX28 processors so it needs to use CONFIG_MX28 guardian to avoid having this code called in others. Signed-off-by: Otavio Salvador <otavio@ossystems.com.br> Acked-by: Marek Vasut <marex@denx.de>
* MX28: config: Allow different target generation in elftosb callOtavio Salvador2012-09-01-0/+0

* MX28: Drop the cp15 reconfiguration from SPLMarek Vasut2012-09-01-42/+0
| | | | | | | | | | | | | | | The SPL doesn't need the CP15 reconfiguration, as that's what the BootROM does for us already. Moreover, when the CP15 is reconfigured and the code returns control to BootROM, the USB boot works no more. Remove the code and allow [1] to work properly as well.
