ZynqMP:
- Syncup DT with Linux kernel
- Fix mmc mini configurations via DT
- Add pinctrl/psgtr description to DTs
- Add DTs for Kria boards
- Enable RTC and Time commands

Versal:

Right now U-Boot is not aware about date/time that's why enable it by
default also with EFI runtime service for setting time.

Signed-off-by: Michal Simek <michal.simek@xilinx.com>

U-Boot expects to be linked to a specific hard-coded address and to
be loaded to and run from that address. CONFIG_POSITION_INDEPENDENT
config lifts that restriction & allowing the code to be loaded to
and executed from almost any address.

As we enabled CONFIG_POSITION_INDEPENDENT, CONFIG_INIT_SP_RELATIVE
is enabled by default, where it will set the early stack pointer at
runtime by adding an offset value to &_bss_start. The offset value
is taken from SYS_INIT_SP_BSS_OFFSET.

SYS_INIT_SP_BSS_OFFSET offset should be large enough so that the
early malloc region, global data (gd), and early stack should fit.
With commit d8fabcc424bd ("arm64: versal: Increase SYS_MALLOC_F_LEN")
SYS_MALLOC_F_LEN is increased from 32KB to 1MB, so we need to
accommodate this space with SYS_INIT_SP_BSS_OFFSET. Hence increasing
SYS_INIT_SP_BSS_OFFSET to 1.5MB.

I2C muxes that have the slave devices with same address are
falling into the below problem.

VCK190 system controller (SC) - zynqmp-e-a2197-00-revA.dts
I2C1 (0xff030000) -> Mux1 (@0x74) -> Channel 3 -> 0x50
I2C1 (0xff030000) -> Mux2 (@0x75) -> Channel 0 -> 0x50

1. SC accesses I2C1 - Mux1 (0x74) - Channel 3 and then
2. SC accesses I2C1 - Mux2 (0x75) - Channel 0.

Now it results in 2 slave devices with same address (0x50)
on the I2C bus, making the communication un-reliable.

When ' i2c-mux-idle-disconnect' is in DT, after '1', the Mux
channel output is disconnected, making none of the channels
available to the I2C1. So, there is no question of having the
same addressed slave (0x50) present on the bus when we are doing '2'.

Same pattern is seen in below two boards also.

ZCU208 - zynqmp-zcu208-revA.dts
ZCU216 - zynqmp-zcu216-revA.dts

Add 'default y'.

Ilias Apalodimas authored 3 years ago and Heinrich Schuchardt committed 3 years ago

Up to now we are stopping the EFI subsystem if a TPMv2 exists but the
protocol fails to install.  Now that we've switched the config to 'default
y' the sandbox TPM fails, since it doesn't support all the required
capabilities of the protocol.

Not installing the protocol is not catastrophic.  If the protocol fails
to install the PCRs will never be extended to the expected values, so
some other entity later in the boot flow will eventually figure it out
and take the necessary actions.

While at it fix a corner case were the user can see an invalid error
message when the protocol failed to install.  We do have a tcg2_uninit()
which we call when the protocol installation fails.  There are cases though
that this might be called before the configuration table is installed (e.g
probing the TPM for capabilities failed).  In that case the user will see
"Failed to delete final events config table".  So stop printing it since it's
not an actual failure , simply because the config table was never installed
in the first place.

In order to stop printing it make efi_init_event_log() and create_final_event()
cleanup themselves and only call tcg2_uninit() when the protocol installation
fails.

This is same issue as https://bugzilla.redhat.com/show_bug.cgi?id=1733817

,
but that fix was wrongly partial reverted.

When reading a directory, EFI_BUFFER_TOO_SMALL should be returned when
the supplied buffer is too small, so a use-case is to call
EFI_FILE_PROTOCOL.Read() with *buffer_size=0 and buffer=NULL to
obtain the needed size before doing the actual read.

So remove the check only for directory reading, file reading already
do the check by itself.

If CONFIG_SHA_HW_ACCEL=y, these functions are used.

We already have boards using CONFIG_SHA_HW_ACCEL=y but none implements the

For implementing the EFI TCG2 protocol we need SHA384 and SHA512. The
missing hardware acceleration functions lead to build errors on boards like
peach-pi_defconfig.

Introduce a new Kconfig symbol CONFIG_SHA512_HW_ACCEL to control if the

Versions of U-Boot before 2014.01 created a symlink from include/asm to
the architecture-specific header directory.

If an ARM board is build with that old version, then sandbox is built on
a more recent version (both with in-tree builds), the include/asm symlink
confuses the build system. It picks up the ARM headers when it should be
using the sandbox ones.

Since 2014 U-Boot has only created a symlink inside the include/asm/
directory and only for out-of-tree builds. So for in-tree builds it does
not expect to see an include/asm symlink. It is not removed by
'make mrproper'. It does show up with 'git status' but is easy enough to
miss.

Add include/asm to the files to remove with 'make mkproper'. For recent
U-Boot builds this has no effect, since include/asm is a directory, not a
file. If the include/asm symlink is there, it will be removed.

Python3 taken from the PATH causes build issues when pylibfdt bindings are
generated with Yocto SDK.

Python3 provided as a part of SDK is not compatible with host Python3,
therefore binding build breaks with following errors:

scripts/dtc/pylibfdt/libfdt_wrap.c:154:11: fatal error: Python.h: No such file or directory
  154 | # include <Python.h>
      |           ^~~~~~~~~~

Do not enforce the python3 from the PATH and make it conditionally-assigned
so it can be overridden from outside of build system. Keep the default
assignment to point to version that is taken from the PATH.

Similar fix has been introduced in b48bfc74 ("tools: allow to override
python"), where conditional assignment is used for python executable to
address similar build errors.
