2018-10-09dm: core: Add a function to find the first inactive childSimon Glass1-0/+15
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 Glass1-12/+12
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 Glass1-0/+3
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 Glass1-10/+0
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>
2018-10-09sandbox: tpm: Enhance to support the latest Chromium OSSimon Glass1-0/+34
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 Glass2-0/+15
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>
2018-10-09sandbox: video: Speed up video outputSimon Glass1-1/+3
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.

At present files are not truncated on writing. This is a useful feature. Add support for this. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-09log: Add helpers for common log levelsSimon Glass1-0/+14
At present to output a log message you need something like: log(UCLASS_SPI, LOCL_INFO, "message1"); log(UCLASS_SPI, LOCL_INFO, "message2"); but many files use the same category throughout. Also it is helpful to shorten the length of log names, providing helpers for common logging levels. Add some macros so that it is possible to do: (top of file, before #includes) #define LOG_CATEGORY UCLASS_SPI (later in the file) log_info("message1"); log_debug("message2"); log_err("message3"); Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-08log: Correct definition of log_msg_ret()Simon Glass1-1/+1
This macro should have two parameters, not one. Fix it so that it correctly resolves to _ret when logging is disabled. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-10-08sandbox: Unprotect DATA regions in bus testsSimon Glass1-0/+12
On my Ubuntu 18.04.1 machine two driver-model bus tests have started failing recently. The problem appears to be that the DATA region of the executable is protected. This does not seem correct, but perhaps there is a reason. To work around it, unprotect the regions in these tests before accessing them. Signed-off-by: Simon Glass <sjg@chromium.org>

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.

Instead of manually specifying CONFIG_SYS_EXTRA_ENV_RELOC for every board that needs it, it shouldn't hurt to let initr_reloc_global_data() always relocate gd->env_addr unless we know this pointer is outside the initial binary.

Here we do a couple of impovements for all ARC boards as well as introduce yet another developemnt board. 1. Now for ARC boards we print CPU and board info which is useful for users and helps with analysis of logs "post-mortem". 2. Synopsys IoT development kit support is added This one might bw a bit too late as we're past RC1 but: 1) This doesn't affect any other arches etc as we change purely ARC code. 2) I've got a chance to talk about U-Boot on IoT platforms during ELCE (my proposal was on a wait list and only this week I've got an update and invitation to talk) so it would be good to have this board as a primer in upstream code-base by the time of ELCE 2018. 3) For complete support of IoT devkit I'm yet to significantly rework regmap subsystem in U-Boot but that's a different topic and hopefully it will be done sometime soon... though not this release cycle for sure.
2018-10-05arc: Add support for IoT development kitAlexey Brodkin1-0/+84
The DesignWare ARC IoT Development Kit is a versatile platform that includes the necessary hardware and software to accelerate software development and debugging of sensor fusion, voice recognition and face detection designs. More information is avaialble here [1] and here [2]. The board is based on real silicon with ARC EM9D-based Data Fusion IP Subsystem. It sports a rich set of I/O including * DW USB OTG * DW MobileStorage (used for micro SD-card) * GPIO * multiple serial interface including DW APB UART * ADC, PWM and eFlash, SRAM and SPI Flash memory * Real-Time Clock (RTC) * Bluetooth module with worldwide regulatory compliance (FCC, IC, CE, ETSI, TELEC) * On-board 9-axis sensor (gyro, accelerometer and compass) Extensible with Arduino, Pmod, mikroBUS connectors and a 2x18 extension header. One of the most interesting features for developers is built-in Digilent USB JTAG probe so only micro-USB cable is needed!

2018-10-04spl: add support to booting with OP-TEEKever Yang1-0/+13

2018-10-03riscv: Add QEMU virt board supportBin Meng1-0/+21
This adds QEMU RISC-V 'virt' board target support, with the hope of helping people easily test U-Boot on RISC-V. The QEMU virt machine models a generic RISC-V virtual machine with support for the VirtIO standard networking and block storage devices. It has CLINT, PLIC, 16550A UART devices in addition to VirtIO and it also uses device-tree to pass configuration information to guest software. It implements RISC-V privileged architecture spec v1.10. Both 32-bit and 64-bit builds are supported. Support is pretty much preliminary, only booting to U-Boot shell with the UART driver on a single core. Booting Linux is not supported yet.

2018-10-02mtd: mtdpart: implement proper partition handlingMiquel Raynal2-1/+32
Instead of collecting partitions in a flat list, create a hierarchy within the mtd_info structure: use a partitions list to keep track of the partitions of an MTD device (which might be itself a partition of another MTD device), a pointer to the parent device (NULL when the MTD device is the root one, not a partition). By also saving directly in mtd_info the offset of the partition, we can get rid of the mtd_part structure.

Using an MTD device (resp. partition) name in mtdparts is simple and straightforward. However, for a long time already, another name was given in mtdparts to indicate a device (resp. partition) so the "mtdids" environment variable was created to do the match. Let's create a function that, from an MTD device (resp. partition) name, search for the equivalent name in the "mtdparts" environment variable thanks to the "mtdids" string.

2018-10-02mtd: mtdpart: add a generic mtdparts-like parserMiquel Raynal1-0/+21
The current parser is very specific to U-Boot mtdparts implementation. It does not use MTD structures like mtd_info and mtd_partition. Copy and adapt the current parser in drivers/mtd/mtd-uclass.c (to not break the current use of mtdparts.c itself) and write some kind of a wrapper around the current implementation to allow other commands to benefit from this parsing in a user-friendly way. This new function will allocate an mtd_partition array for each successful call. This array must be freed after use by the caller. The given 'mtdparts' buffer pointer will be moved forward to the next MTD device (if any, it will point towards a '\0' character otherwise).
