In some cases, UART is configured by early boot stage.
To be sure of the initial state of UART and to avoid
spurious chars on console, reset the serial block before
configuring it.

Commit 4687919684e0 ("serial: Remove DM_FLAG_PRE_RELOC flag in various
drivers") essentially drops flag DM_FLAG_PRE_RELOC from serial_pl01x
driver for Poplar platform, because the platform falls into the
following strategy category made by the commit.
Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for
drivers that support both statically declared devices and
configuration from device tree
Before the commit lands, Poplar platform works by statically declaring
pl011 serial device via U_BOOT_DEVICE() with DM_FLAG_PRE_RELOC flag set
in the driver. But since Poplar also supports device configuration from
device tree, the commit practically drops the flag for Poplar, and hence
breaks the platform from booting.
This patch changes platform code and device tree to initiate pl011
serial device from device tree rather than static declaration, so that
above strategy about DM_FLAG_PRE_RELOC applies to Poplar, and therefore
the reported boot failure gets fixed.

The motivation for this is to allow distributions to distribute all
possible tools in a generic way, avoiding the need of specific tools
building for each machine.
Especially on OpenEmbedded / Yocto Project ecosystem, it is very
common each BSP to end providing their specific tools when they need
to generate images for some SoC (e.g MX23 / MX28 in meta-freescale
case).
Using this, we can package the tools doing:
$: make tools-only_defconfig
$: make tools-only

If OP-TEE core is compiled with support of REE FS and RPMB
at the same time (CFG_RPMB_FS ?= y; CFG_RPMB_FS ?= y), and persistent
storage API is used with TEE_STORAGE_PRIVATE storage id, it will
lead to TA panic.
E/TC:? 0 TA panicked with code 0xffff0009
.....
E/TC:? 0 Call stack:
E/TC:? 0 0x000000004002f2f8 TEE_OpenPersistentObject at
lib/libutee/tee_api_objects.c:422
In this particular case TEE_ERROR_STORAGE_NOT_AVAILABLE is more suitable
than TEE_ERROR_NOT_IMPLEMENTED, as it provides to a TA a possibility
to handle this error code [1].
>From GPD TEE Internal Core specification [2]:
TEE_ERROR_STORAGE_NOT_AVAILABLE - if the persistent object is stored in a
storage area which is currently inaccessible. It may be associated with
the device but unplugged, busy, or inaccessible for some other reason.

Complete conversion of sound to driver model
|
|
At present the 'beep' sound generates a waveform for only one channel even
if two are being used. This means that the beep is twice the frequency it
should be. Correct this by making it a parameter.
The fix in a previous commit was correct for sandbox but not for other
boards.

The sound driver pulls together the audio codec and i2s drivers in order
to actually make sounds. It supports setup() and play() methods. The
sound_find_codec_i2s() function allows locating the linked codec and i2s
devices. They can be referred to from uclass-private data.

At present we use a single buffer for sound which means we cannot be
playing one sound while queueing up the next. This wouldn't matter except
that a long sound (more than a second) has to be created as a single
buffer, thus using a lot of memory. To better mimic what real sound
drivers do, add support for double buffering in sandbox.
