11e10bfcec ARM: rpi_*_defconfig: Add support to find UUID for filesystem
The most generic way of having a stable boot behavior is to rely on
UUID instead of device names for root partition, so the order of
probing does not cause issues with booting.

This enables the `CMD_FS_UUID` for following defconfig files:

 - rpi_0_w_defconfig
 - rpi_2_defconfig
 - rpi_3_32b_defconfig
 - rpi_3_defconfig
 - rpi_defconfig

af765a49ba rockchip: rk3399: Initialize CPU B clock.
This patch sets the PLL of CPU cluster B (BPLL) to 600 MHz.
This decreases the boot time of Linux 4.19 by about 8%.

The 600 MHz are inspired by the 600 MHz used for LPLL initialization
(came in with commit 9f636a249c).

a73610d2c6 rtc: rv3029: update to support DM and sync with Linux 4.17
The "Flamingo" carrier-board for the RK3399-Q7 has a RV3029 populated
and the application will use the off-module RV3029 RTC including the
battery backed SRAM.

To support this use case, this commit includes the following changes:
 * updates the rv3029 driver to use DM
 * implements the read8/write8 operations

This syncs the implementation with the Linux code (based on 4.17),
porting the trickle-charger support from there (with improvements to
avoid unnecessary EEPROM updates) and adheres to the Linux DTS
binding.

765246a18c rockchip: rk3399-puma: reduce sd card max-frequency to 40MHz
Some SanDisk Ultra cards trigger intermittent errors on detection
resulting in an -EOPNOTSUPP, when running at 50MHz.

Waveform analysis suggest that the level shifters that are used on the
RK3399-Q7 module (for voltage translation between the on-module
voltages and the 3.3V required on the card-edge) don't handle clock
rates at or above 48MHz properly. This change reduces the maximum
frequency on the external SD-interface to 40MHz (for a safety margin
of 20%).

adbca53a3a rockchip: rk3399: spl: always report errors triggering a hard stop
The RK3399 SPL has two cases that may end in a hard-stop: if either
the pinctrl can not be initialised or if the DRAM fails to initialise.
Both have previously not triggered an error message unless DEBUG was
defined (i.e. both used debug() to print the error).

This converts both error messages to be printed using pr_err() to
ensure that some output points to the cause of the hard-stop.

Commit 7a6d7d3e12 ("rockchip: pinctrl: rk3188: Move the iomux definitions
into pinctrl-driver") moved the iomux settings out of the grf header
to prevent conflicts with the iomux definitions of other rockchip socs.

This also breaks the early uart setup, as the iomux for uart2 are needed.
To fix that just put the tiny amount of needed iomux definitions next to
the early uart code.

51f00c1704 tpm: Export the open/close functions
At present these functions are not accessible outside the TPM library, but
in some cases we need to call them. Export them in the header file and add
a define for the SHA1 digest size.

Also adjust tpm_open() to call tpm_close() first so that the TPM is in a
known state before opening (e.g. by a previous phase of U-Boot).

07e127d85d tpm: Add a constant for the minimum supported digest size
When SHA1 is used we need 20 bytes for the digest size. Add a constant so
that clients can make use of this, e.g. to allocate local buffers.

8244127db9 cmd, fdt: add subcommand "get" to fdt header
store fdt header member with name <member> in U-Boot
Environment variable with name <var>.

for example to get the total length of the fdt and store
it in filesize, call:

fdt header get filesize totalsize

For membernames look into fdt header definition at
scripts/dtc/libfdt/libfdt.h

b847c14243 sandbox: Use memmove() to move overlapping regions
The use of strcpy() to remove characters at the start of a string is safe
in U-Boot, since we know the implementation. But in os.c we are using the
C library's strcpy() function, where this behaviour is not permitted.

Update the code to use memmove() instead.

856b8f5629 sound: sandbox: Use the correct frequency
At present we request a particular frequency but we may not get the exact
same frequency in response. So use the actual frequency for generation of
the square wave. This ensures that the pitch remains accurate on all host
machines.

7d92b06090 sound: Add sample rate as a parameter for square wave
At present this value is hard-coded in the function that generates a
square wave. Since sample rates vary between different hardware, it makes
more sense to have this as a parameter.

Update the function and its users.

b7c25b11b6 dm: sandbox: i2c: Add a new 'emulation parent' uclass
Sandbox i2c works using emulation drivers which are currently children of
the i2c device:

	rtc_0: rtc@43 {
		reg = <0x43>;
		compatible = "sandbox-rtc";
		emul {
			compatible = "sandbox,i2c-rtc";
		};
	};

In this case the emulation device is attached to i2c bus on address 0x43
and provides the Real-Time-Clock (RTC) functionality.

However this is not ideal, since every device on an I2C bus has a child
device. This is only really the case for sandbox, but we want to avoid
special-case code for sandbox.

A better approach seems to be to add a separate node on the bus, an
'emulation parent'. This can be given a bogus address (such as 0xff) and
hides all the emulators away. Then we can use a phandle to point from the
device to the correct emualtor, and only on sandbox. The code to find an
emulator does not interfere with normal i2c operation.

Add a new UCLASS_I2C_EMUL_PARENT uclass which allows finding an emulator
given a bus, and finding a bus given an emulator. This will be used in a
follow-on patch.
