2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini30-66/+30
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2017-11-06MAINTAINERS: Add missing boards and config entriesTom Rini1-1/+2
As part of my usual round of build testing, output about missing MAINTAINERS information was not logged, and thus often overlooked. Correct that mistake by ensuring that I log the output of genboardscfg.py every time. As part of that, address a number of missing MAINTAINERS entires. In the case of a missing file, I have put the original submitter down. In the rest of the cases I have added the config (and sometimes relevant header file) to the existing set of file globs.

2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada1-3/+3
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory.

2016-09-27ARM: tegra: fix ULPI PHY on Ventana and SeaboardStephen Warren1-1/+7
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.

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.

2016-01-28ARM: tegra: rm Jetson TK1 PMIC GPIO programmingStephen Warren1-13/+0
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 Warren1-0/+9
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>
