2016-09-27ARM: tegra: fix ULPI PHY on Ventana and SeaboardStephen Warren
Commit ce02a71c2374 "tegra: dts: Sync tegra20 device tree files with Linux" enabled the ULPI USB port on Ventana, but made no attempt to ensure that U-Boot code could handle this. In practice, various code is missing, and various configuration options are not enabled, which causes U-Boot to hang when attempting to initialize this USB port. This patch enables ULPI PHY support on Ventana, and adds the required pinmux setup for the port to operate. Note that Ventana is so similar to Seaboard that this change is made in the Seaboard board file, which is shared with Ventana. Seaboard also has the ULPI USB port wired up in hardware, although to an internal port that often doesn't have anything attached to it. However, the DT nodes for the USB controller and PHY had different status property values, so the port was not initialized by U-Boot. Fix this inconsistency, and enable the ULPI port, just like in the Linux kernel DT. This likewise requires enabling ULPI support in the Seaboard defconfig.

2016-09-01ARM: tegra: Add support for TK1-SOM board from Colorado EngineeringPeter Chubb
The Colorado TK1 SOM is a small form factor board similar to the Jetson TK1. The main differences lie in the pinmux, and in that the PCIe controller is set to use in 4lanes+1lane, rather than 2+2. The pinmux header here was generated from a spreadsheet provided by Colorado Engineering using the tegra-pinmux scripts. The spreadsheet was converted from v09 to v11 by me.

2016-05-31ARM: tegra: add p2771-0000 board supportStephen Warren
P2771-0000 is a P3310 CPU board married to a P2597 I/O board. The combination contains SoC, DRAM, eMMC, SD card slot, HDMI, USB micro-B port, Ethernet, USB3 host port, SATA, PCIe, and two GPIO expansion headers. Currently, due to U-Boot's level of support for Tegra186, the only features supported by U-Boot are the console UART and the on-board eMMC. Additional features will be added over time. U-Boot has so far been tested by replacing the kernel image on the device with a U-Boot binary. It is anticipated that U-Boot will eventually replace the CCPLEX bootloader binary, as on previous chips. This hasn't yet been tested.

This imports v11 of "Jetson TK1 Development Platform Pin Mux" from https://developer.nvidia.com/embedded/downloads. The new version defines the mux option for the MIPI pad ctrl selection. The OWR pin no longer has an entry in the configuration table because the only mux option it support is OWR, that feature isn't supported, and hence can't conflict with any other pin.

2016-01-28ARM: tegra: rm Jetson TK1 PMIC GPIO programmingStephen Warren
The PMIC is configured such that its GPIOs have the correct configuration at power-up, so no programming is required. In fact, the current programming is actively wrong, since: (a) the AS3722 driver configures the GPIO to be an output before setting its output value, which causes a 0v glitch on the output. (b) the AS3722 driver configures the GPIO to drive a high voltage from its VSUP_GPIO power source rather than its VDD_GPIO_LV power source, so the pin drives 5V not 1.8V as desired. Solve these problems by removing the code which configures the PMIC GPIOs. Note that this patch was tested directly on top of v2016.01; since then, commit 96350f729c42 "dm: tegra: net: Convert tegra boards to driver model for Ethernet" prevents PCIe from being initialized. Alternatively, simply revert that commit to get PCIe Ethernet working again, then apply this patch to test.

2015-03-04ARM: tegra: support running in non-secure modeStephen Warren
When the CPU is in non-secure (NS) mode (when running U-Boot under a secure monitor), certain actions cannot be taken, since they would need to write to secure-only registers. One example is configuring the ARM architectural timer's CNTFRQ register. We could support this in one of two ways: 1) Compile twice, once for secure mode (in which case anything goes) and once for non-secure mode (in which case certain actions are disabled). This complicates things, since everyone needs to keep track of different U-Boot binaries for different situations. 2) Detect NS mode at run-time, and optionally skip any impossible actions. This has the advantage of a single U-Boot binary working in all cases. (2) is not possible on ARM in general, since there's no architectural way to detect secure-vs-non-secure. However, there is a Tegra-specific way to detect this. This patches uses that feature to detect secure vs. NS mode on Tegra, and uses that to: * Skip the ARM arch timer initialization. * Set/clear an environment variable so that boot scripts can take different action depending on which mode the CPU is in. This might be something like: if CPU is secure: load secure monitor code into RAM. boot secure monitor. secure monitor will restart (a new copy of) U-Boot in NS mode. else: execute normal boot process Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
