07bc873c73 ctags: Minor changes to fix ctags output
At present ctags emits lines with unmatched quotes which means that the
output file is invalid. This is with exuberant-ctags version 5.9~svn201103
but I also see it with plain ctags. I am not sure that it is a bug though.

Make a few minor changes in the source code to fix this problem.

At present the panel can be turned on but not off, and the brightness
cannot be controlled at run-time. Add a new API function to both the panel

6f1c0430e8 cros: Update ec_commands to latest version
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.

4af3e9ad8a sandbox: Restore blocking I/O on exit
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.

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

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.

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.

5396e8b1dd arc: Add support for IoT development kit
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!

70fe287635 spl: add support to booting with OP-TEE
OP-TEE is an open source trusted OS, in armv7, its loading and
running are like this:
loading:
- SPL load both OP-TEE and U-Boot
running:
- SPL run into OP-TEE in secure mode;
- OP-TEE run into U-Boot in non-secure mode;

To make code simple, it would be fine to use IH_OS_TEE for the
os tyle in TPL(just like IH_OS_LINUX is using both in SPL and U-Boot).

Here is the diagram for SPL loading OP-TEE,

510e379c49 riscv: Add QEMU virt board support
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.

5db66b3aee cmd: mtd: add 'mtd' command
There should not be a 'nand' command, a 'sf' command and certainly not
a new 'spi-nand' command. Write a 'mtd' command instead to manage all
MTD devices/partitions at once. This should be the preferred way to
access any MTD device.

2a74930da5 mtd: mtdpart: implement proper partition handling
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.

ff4afa8a98 mtd: uboot: search for an equivalent MTD name with the mtdids
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.
