There is really no need to provide an empty reset_cpu() implementation, so just remove it. Cc: Tim Harvey <tharvey@gateworks.com> Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Tim Harvey <tharvey@gateworks.com>

2015-09-02imx: mx6: ddr init MMDC according to ddr_typePeng Fan
To i.MX6, DDR3 and LPDDR2 is supported, so rename function mx6_dram_cfg to mx6_ddr3_cfg and the original mx6_dram_cfg function only is a wrapper. The new reimplemented function mx6_dram_cfg only invokes mx6_ddr3_cfg when ddr_type is for DDR3. Later we can use ddr_type to initialize MMDC for LPDDR2. Initialize ddr_type for different boards which enable SPL.

If the EEPROM could not be read or is corrupt we always want to hang. Note that an error message will have been displayed by read_eeprom in this case. Signed-off-by: Tim Harvey <tharvey@gateworks.com>
2015-06-01imx: ventana: make fdt_file1 and fdt_file2 automatic and non-overridableTim Harvey
The fdt_file1 and fdt_file2 vars provide fallbacks for the fdt file loading script. There is no need to allow the user to override these as if they want to specify the fdt, they should do so in the first attempt which is the fdt_file var. Signed-off-by: Tim Harvey <tharvey@gateworks.com>

We want to model env var to always reflect what was in the EEPROM. There is no point in allowing a user to override this. Signed-off-by: Tim Harvey <tharvey@gateworks.com>

2015-05-21imx: ventana: config: enable Falcon modeTim Harvey
Falcon mode entails the SPL booting the OS directly instead of U-Boot. Signed-off-by: Tim Harvey <tharvey@gateworks.com>
2015-05-19imx: ventana: add pmic_setup to SPLTim Harvey
We need to do any PMIC setup in the SPL if we are to bypass U-Boot for falcon mode. Signed-off-by: Tim Harvey <tharvey@gateworks.com>
2015-05-15imx: ventana: use stack relocationTim Harvey
Certain features we desire require a larger stack than is available by using iRAM (most notably for us, env_mmc). Relocate the stack to DRAM so that we can use these features. Signed-off-by: Tim Harvey <tharvey@gateworks.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2015-05-15imx: ventana: add GSC boot watchdog disable to SPLTim Harvey
If the SPL is to be used for Falcon mode then we need to make sure the SPL disable the GSC boot watchdog. Signed-off-by: Tim Harvey <tharvey@gateworks.com>
2015-05-15imx: ventana: add gpio setup to SPLTim Harvey
If the SPL is to be used for Falcon mode then we need to make sure it configures basic GPIO (iomux, padconf, and default output levels). Signed-off-by: Tim Harvey <tharvey@gateworks.com>

Now that uart and i2c setup functions have been moved to common.c we can use these and remove code duplication. Signed-off-by: Tim Harvey <tharvey@gateworks.com>
2015-05-15imx: ventana: detect pmic using i2c probe instead of board modelTim Harvey
Avoid requiring board-model and probe pmic by its i2c address. This is in preparation for being able to call pmic_setup() from SPL and not need board type. Signed-off-by: Tim Harvey <tharvey@gateworks.com>

2015-05-15imx: ventana: split out common functions between SPL and ubootTim Harvey
Move shared functions used by both SPL and U-Boot to common.c: - setup_iomux_uart() and uart pad config - gpio pad config In the process also moved the following to common.c in preparation for calling it from the SPL: - split i2c setup into a shared function - move pmic init to setup_pmic() function to call directly from power_init_board() - split gpio setup into early (iomux and default pin config) and late (output configuration based on env) Signed-off-by: Tim Harvey <tharvey@gateworks.com>
2015-05-15imx: ventana: default msata/pci mux to pci before PCI enumerationTim Harvey
PCI enumeration occurs early, before we fully configure our GPIO's. Make sure we steer the MSATA/PCI mux to PCI in board_init to ensure PCI is selected before enumeration. Signed-off-by: Tim Harvey <tharvey@gateworks.com>

This fixes a regression caused by e25fbe3fe531029dc7b100ea4c79dbc802e17fc2 (gw_ventana: Move the DCD settings to spl code) The clock gating must be setup prior to calling arch_cpu_init().

2015-04-22imx: ventana: set HDMI video in to yuv422bt656 for GW551x-ATim Harvey
The initial revision of the GW551x does not connect enough signals between the HDMI receiver and the IMX6 CSI for 16bit capture mode necessary for yuv422smp capture. Future revisions will, but for the initial rev force it to yuv422bt656 mode which requires an 8bit video data bus. Signed-off-by: Tim Harvey <tharvey@gateworks.com>
2015-04-22imx: ventana: use hdmiinfmt env var to override HDMI capture formatTim Harvey
The HDMI receiver used on the GW54xx and GW551x has a 16bit video data bus interconnect between it and the IMX6 CSI. This can be used in two different modes, each having advantages and disadvantages. Allow the hdmiinfmt env var to specify which format is desired (yuv422smp or yuv422bt656). Signed-off-by: Tim Harvey <tharvey@gateworks.com>

2015-04-22imx: ventana: add 'gsc wd' command for enabling and disabling GSC watchdogTim Harvey
This adds information about the Gateworks System Controller to the gsc command such as the firmware version, firmware CRC and status of the GSC watchdog (if its enabled and if its tripped). Additionally the 'gsc wd' command can be used to enable or disable the watchdog with the following usage: gsc wd enable [30|60] gsc wd disable Note that the GSC registers are battery-backed by the GSC coincell so once eanbled, they remain enabled across power-cycles or until either the GSC firmware has been updated or FLASH has been re-programmed by the Gateworks JTAG adapter.

2015-04-22imx: ventana: add DT fixup for GW54xx compatibility with older kernelsTim Harvey

2015-04-22imx: ventana: added DT fixup for GW551x-A video inputTim Harvey
The GW551x-A revision does not have the CSI0_DATA_EN pin connected, therefore we need to make sure that signal is not muxed to the CSI_DATA_EN signal internally and do so by steering it to the unused GPIO5_IO20. We do this so that the kernel device-tree can properly define the signal for RevB and beyond boards that do have this hooked up properly and require it.

2015-04-22imx: ventana: disable IMX6 watchdogs on GW51xx RevA and RevBTim Harvey
A board level errata causes the IMX6 watchdog to be unstable on the GW51xx RevA and RevB boards which can cause the watchdog to trip extremely early (under 5seconds) under certain operating conditions.

2015-04-22imx: ventana: set LTC3676 PMIC to appropriate values per datasheetTim Harvey
The IMX6 Datasheets specifies that when the IMX6 LDO is enabled (internal Anatop LDO's for VDD_ARM, VDD_SOC, and VDD_xPU) you need to provide 1350mV on VDD_ARM_IN and VDD_SOC_IN for IMX6Q@1GHz (Automotive) and 1275mV for IMX6DL@800MHz (Industrial). While we are still about 50mV shy on the IMX6Q operating at 1GHz we set it to the max we can and leave it up to the kernel to implement a regulator driver for the LTC3676 and put the LDO's in bypass mode which allows us to drop the voltages by 125mV respectively.
