P2020 DTS files in upstream Linux kernel use fsl/p2020si-pre.dtsi and
fsl/p2020si-post.dtsi include device tree files.
Add symlinks for these include device tree files into U-Boot powerpc
directory and points them to U-Boot inline device tree files p2020.dtsi and
p2020-post.dtsi.
This allows to use P2020 DTS files from upstream Linux kernel in U-Boot.

If env is stored on SD card then U-Boot SPL automatically calls mmc_init()
before it is going to load proper U-Boot from SD card.
If env is not stored on SD card then U-Boot SPL fails to read proper U-Boot
from SD card due to missing mmc_init() call.
So add missing mmc_init() call into fsl_esdhc_spl's mmc_boot() function.
It fixes booting from SD card on P2020 boards without env support in SPL.
mmc_init() returns early if card was already initialized, so there is no
issue with calling this function more times.

In pre-PBL header is stored size of code which BootROM copies from SD card
to L2/SRAM. This size has upper limit of L2 cache size. In most cases this
is size of U-Boot SPL or size of L2 cache.
Therefore this size in pre-PBL header cannot be used for determining size
of proper U-Boot.
So always use CONFIG_SYS_MMC_U_BOOT_SIZE for determining size of proper
U-Boot which stored on SD card.

There is an user-selectable SYS_HAS_ARMV8_SECURE_BASE, which has the

uses this, drop it and replace it with something more sophiticated:
ARMV8_PSCI_RELOCATE. This option will then enable the ARMV8_SECURE_BASE
option which is used as the base to relocate the PSCI code (or any code
in the secure region, but that is only PSCI). A SoC (or board) can now
opt-in into having such a secure region by enabling
SYS_HAS_ARMV8_SECURE_BASE. Enable it for the LS1043A SoC, where it was
possible to relocate the PSCI code before as well as on the LS1028A SoC
where there will be PSCI support soon.

There are two different implementations to do a secure monitor call:
smc_call() and arm_smccc_smc(). The former is defined in fwcall.c and
seems to be an ad-hoc implementation. The latter is imported from linux.
smc_call() is also only available if CONFIG_ARMV8_PSCI is not defined.
This makes it impossible to have both PSCI calls and PSCI implementation
in one u-boot build. The layerscape SoC code decide at runtime via
check_psci() if there is a PSCI support. Therefore, this is a
prerequisite patch to add PSCI implementation support for the layerscape
SoCs.

Unless you have a spare Apple Silicon machine, getting access to
the serial port on Apple Silicon machines requires special
hardware. Given that most machines come with a built-in screen
the framebuffer is likely to be the most convenient output device
for most users. While U-Boot will output to both serial and
framebuffer, OSes might not. Therefore set stdout-path to point
at /chosen/framebuffer when a keyboard is connected to the machine.
This behaviour can be overridden by setting the "stdout" variable
in the U-Boot environment. I addition to that keep the serial
console as the default when running under the m1n1 hypervisor.
The m1n1 hypervisor virtualizes the serial port such that it
can be easily accessed from any other machine with a USB port.

Commit 690af71850 changed this condition
from an explicit
IS_ENABLED(CONFIG_SPL_SEPARATE_BSS)
to
CONFIG_IS_ENABLED(SEPARATE_BSS)
The documentation for CONFIG_IS_ENABLED() in include/linux/kconfig.h
implies that we will get the correct behaviour, but the actual behaviour
differs such that this condition is now always false.
This stopped TPL being able to load the device tree blob at least on the
ROCKPro64 board (RK3399 SoC), since the wrong device tree location was
chosen.
The issues causing this behaviour with CONFIG_IS_ENABLED() are:
1. The documentation implies that CONFIG_SPL_BUILD =>
CONFIG_SPL_<option> is considered before the TPL equivalent.
Actually, the TPL options have higher priority - see definition of
_CONFIG_PREFIX.
2. The documentation implies a fallthrough, eg. if CONFIG_SPL_BUILD is
defined but the CONFIG_SPL_<option> is not, then it will proceed to
check if CONFIG_TPL_BUILD
Actually, if CONFIG_TPL_BUILD is defined, then it stops there
and CONFIG_SPL_BUILD is not considered - see definition of
_CONFIG_PREFIX.
During TPL build, at least for the ROCKPro64, both CONFIG_TPL_BUILD
and CONFIG_SPL_BUILD are defined, but because of the above, only TPL
options are considered. Since there is no CONFIG_TPL_SEPARATE_BSS,
this fails.
