Use PHASE_ as the symbol to select a particular XPL build. This means
that SPL_TPL_ is no-longer set.
Update the comment in bootstage to refer to this symbol, instead of
SPL_

Add True Random Number Generator (TRNG) driver for Exynos chips. This
implementation is heavily based on Linux kernel's counterpart [1]. It
also follows upstream dt-bindings [2].
TRNG block is usually a part of SSS (Security Sub System) IP-core on
Exynos chips. Because SSS access on Exynos850 is protected by TZPC
(TrustZone Protection Control), it's not possible to read/write TRNG
registers from U-Boot, as it's running in EL1 mode. Instead, the
corresponding SMC calls should be used to make the secure software
running in EL3 mode access it for us. Those SMC calls are handled by
LDFW (Loadable Firmware), which has to be loaded first. For example, for
E850-96 board it's done in its board_init(), so by the time RNG
capabilities are needed the LDFW should be already loaded and TRNG
should be functional.

Add SPL variant of DM_RNG so that the DM_RNG can be disabled in SPL
if necessary. This may be necessary due to e.g. size constraints of
the SPL.

Adds to support JH7110 TRNG driver which is based on linux kernel's
jh7110-trng.c. This can support to generate 256-bit random numbers and
128-bit but this makes 256-bit default for convenience.

The Zkr ISA extension (ratified Nov 2021) introduced the seed CSR. It
provides an interface to a physical entropy source.
A RNG driver based on the seed CSR is provided. It depends on
mseccfg.sseed being set in the SBI firmware.

The ARMv8.5 architecture extension defines architectural RNDR/RNDRRS
system registers, that provide 64 bits worth of randomness on every
read. Since it's an extension, and implementing it is optional, there is
a field in the ID_AA64ISAR0_EL1 ID register to query the availability
of those registers.
Add a UCLASS_RNG driver that returns entropy via repeated reads from
those system registers, if the extension is implemented.
The driver always binds, but checks the availability in the probe()
routine.
This helps systems which suffer from low boot entropy, since U-Boot can
provide entropy via the generic UEFI entropy gathering protocol to the OS,
at an early stage.

The TPM device has a builtin random number generator(RNG)
functionality. Expose the RNG functions of the TPM device to the
driver model so that they can be used by the EFI_RNG_PROTOCOL if the
protocol is installed.
Also change the function arguments and return type of the random
number functions to comply with the driver model api.

Adds random number generator driver using Arm SMCCC TRNG interface to
get entropy bytes from secure monitor. The driver registers as an
Arm SMCCC feature driver to allow PSCI driver to bind a device for
when secure monitor exposes RNG support from Arm SMCCC TRNG interface.
