2019-06-05p2771-0000: Add support for framebuffer carveoutsThierry Reding1-4/+62
If early firmware initialized the display hardware and the display controllers are scanning out a framebuffer (e.g. a splash screen), make sure to pass information about the memory location of that framebuffer to the kernel before booting to avoid the kernel from using that memory for the buddy allocator. This same mechanism can also be used in the kernel to set up early SMMU mappings and avoid SMMU faults caused by the display controller reading from memory for which it has no mapping.

2019-06-05ARM: tegra: Unify Tegra186 buildsThierry Reding1-5/+5
Tegra186 build are currently dealt with in very special ways, which is because Tegra186 is fundamentally different in many respects. It is no longer necessary to do many of the low-level programming because early boot firmware will already have taken care of it. Unfortunately, separating Tegra186 builds from the rest in this way makes it difficult to share code with prior generations of Tegra. With all of the low-level programming code behind Kconfig guards, the build for Tegra186 can again be unified. As a side-effect, and partial reason for this change, other Tegra SoC generations can now make use of the code that deals with taking over a boot from earlier bootloaders. This used to be nvtboot, but has been replaced by cboot nowadays. Rename the files and functions related to this to avoid confusion. The implemented protocols are unchanged.

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>

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().

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.
