2018-10-09cros: Update ec_commands to latest versionSimon Glass
This file has changed quite a bit in the last 5 years as the capabilities of the ECs have grown. Sync it up with the copy in coreboot commit b9141f2215. The only change is the addition of EC_VBNV_BLOCK_SIZE_V2. This is needed because U-Boot uses the new v2 vboot API and this is not currently fully supported by Chromium OS firmware.

2018-10-09tpm: Use livetree and allow childrenSimon Glass
Adjust the TPM drivers to use livetree (only one does not). Also, sometimes TPMs can have child devices if they provide a service to the system (such as storing secure data), so permit that. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09video: Adjust video_clear() to return an errorSimon Glass
All driver-model operation should return an error code. Adjust this function to do so also. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Anatolij Gustschin <agust@denx.de>
2018-10-09dm: spi: Add logging of some return valuesSimon Glass
When SPI flash operations fail it is helpful to be able to see the error codes and where they are generated. Add logging to capture this information for read operations. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09cros: Update cros_ec code to use struct udeviceSimon Glass
At present we pass around a private pointer to specify the cros_ec device. With driver model it makes more sense to pass the device. Update the code to do this. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09serial: Allow serial to be absent in TPLSimon Glass
At present this option applies to SPL, but it should be available in TPL also, and separately. Change to using CONFIG_IS_ENABLED(), add a new Kconfig option and fix up hang(). Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09tpm: Add support for SPL and TPLSimon Glass
At present the tpm can only be used in U-Boot proper. Updated it to work in SPL and TPL also. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09fdt: Allow indicating a node is for U-Boot proper onlySimon Glass
At present it is not possible to specify that a node should be used before relocation (in U-Boot proper) without it also ending up in SPL and TPL device trees. Add a new "u-boot,dm-pre-proper" boolean property for this. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09rtc: Allow use of RTC in SPL and TPLSimon Glass
Add Kconfig options so that the RTC can be used in SPL and TPL. This is helpful for accessing the contents of CMOS RAM, for example. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09Kconfig: Convert CONFIG_RTC_MC146818 to KconfigSimon Glass
Move this option to Kconfig and tidy up the two boards which use it. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09blk: Support block drivers in TPLSimon Glass
At present it is not possible to enable/disable block drivers in TPL. This is needed to provide sandbox support. Add a Kconfig option and adjust the Makefile. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09spl: input: Allow input in SPL and TPLSimon Glass
In some cases it is necessary to read the keyboard in early phases of U-Boot. Update the config to allow this. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09sf: Avoid allocating memory on every read operationSimon Glass
At present spi_flash_cmd_read_ops() allocates and frees a few bytes of memory every time it is called. It is faster to use the stack for this and this is now supported by the minimum GCC version required by U-Boot. Remove the allocation and use a variable-sized array instead. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09dm: core: Update ofnode to read binman-style flash entrySimon Glass
At present ofnode_read_fmap_entry() reads a flash map entry in a format which is not supported by binman. To allow use to use binman-format descriptions, update this function. Also add a simple test. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09dm: core: Add a function to find the first inactive childSimon Glass
Some devices have children and want to press an existing inactive child into service when needed. Add a function to help with this. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09dm: core: Update some functions to use constSimon Glass
Quite a few functions do not actually modify the device that is passed in. Update the function signatures to reflect that. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09dm: core: Alloc uclass-private data to be cache-alignedSimon Glass
There is no reason why this feature should not be supported for uclass- private data. Update the code accordingly. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09sandbox: Restore blocking I/O on exitSimon Glass
At present sandbox sets non-blocking I/O as soon as any input is read from the terminal. However it does not restore the previous state on exit. Fix this and drop the old os_read_no_block() function. This means that we always enable blocking I/O in sandbox (if input is a terminal) whereas previously it would only happen on the first call to tstc() or getc(). However, the difference is likely not important. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09dm: spi: Clean up detection of sandbox SPI emulatorSimon Glass
Now that we don't have to deal with the command-line flag we can simplify the code for detecting the emulator. Remove the lookup based on the SPI specification, relying just on the device tree to locate the emulator. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09sandbox: tpm: Enhance to support the latest Chromium OSSimon Glass
This driver was originally written against Chromium OS circa 2012. A few new features have been added. Enhance the TPM driver to match. This mostly includes a few new messages and properly modelling whether a particular 'space' is present or not. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09sandbox: tpm: Tidy up enums and return valuesSimon Glass
Use an enum for command values instead of open-coding them. This removes the need for comments. Also make sure the driver returns proper error numbers instead of -1. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09serial: sandbox: Allow serial output without device treeSimon Glass
At present sandbox assumes that device-tree control is active, but this may not be the case in SPL or TPL. Add some conditions to handle this. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09sandbox: Add a debug UARTSimon Glass
Add support for the debug UART so that sandbox provides build testing for this feature. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09sandbox: video: Speed up video outputSimon Glass
At present there are many situations where sandbox syncs the display to the SDL frame buffer. This is a very expensive operation but is only needed every now and then. Update video_sync() so that we can specify whether this operation is really needed. At present this flag is not used on other architectures. It could also be used for reducing writeback-cache flushes but the benefit of that would need to be investigated.

2018-10-09sandbox: spi: Add more loggingSimon Glass
Add logging to aid debugging features in these drivers. Also drop some code in sandbox_spi_xfer() which is not used. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09sandbox: spi: Drop command-line SPI optionSimon Glass
At present we support specifying SPI flash devices to use in the device tree and on the command line. Drop the second option, since it is a pain to support nicely with driver model, and unnecessary. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-08rtc: Add read8 and write8 support to isl1208 driverTrent Piepho
This can be used for device register access from board code. This allows access to capabilities in the RTC chip not abstracted in U-Boot's RTC class. E.g., device NVRAM or a tamper detection circuit.

2018-10-07Add UCLASS_TEE for Trusted Execution EnvironmentJens Wiklander
Adds a uclass to interface with a TEE (Trusted Execution Environment). A TEE driver is a driver that interfaces with a trusted OS running in some secure environment, for example, TrustZone on ARM cpus, or a separate secure co-processor etc. The TEE subsystem can serve a TEE driver for a Global Platform compliant TEE, but it's not limited to only Global Platform TEEs. The over all design is based on the TEE subsystem in the Linux kernel, tailored for U-Boot.

2018-10-04spi: Add SPI driver for MT76xx SoCsStefan Roese
This patch adds the SPI driver for the MediaTek MT7688 SoC (and derivates). Its been tested on the LinkIt Smart 7688 and the Gardena Smart Gateway with and SPI NOR on CS0 and on the Gardena Smart Gateway additionally with an SPI NAND on CS1. Note that the SPI controller only supports a max transfer size of 32 bytes. This driver implementes a workaround to enable bigger xfer sizes to speed up the transfer especially for the SPI NAND support.
