arm64: zynqmp: Enable DP driver for SOMs
The main reason is to send pmufw cfg overlay from U-Boot to PMUFW to enable
access to DP. Overlay is sent when cls command is called and for that IP
has to be enabled in carrier cards.
And IP needs to be also enabled in SOM dt because with DTB reselection new
DT is not parsed in pre reloc U-Boot instance. It is called from board_f
via embedded_dtb_select(). That's why bind function is not able to allocate
memory and it ends up with error:
"Video device 'display@
fd4a0000' cannot allocate frame buffer memory
-ensure the device is set up before relocation"
To avoid this situation DP is placed also to SOM where bind function is
called and frame buffer memory is allocated and just reused after DTB
reselection. Result is the same. There could be a problem in Linux with
different DP configurations but that's need to be solved there because
console should be on from u-boot already.

configs: ti: use standard configuration nodes naming
Currently, any u-boot bootloader for ti armv7 platforms using
DEFAULT_FIT_TI_ARGS to boot with a fitimage (boot_fit = 1)
doesn't boot when built with Yocto Poky (openembedded-core).
## Loading kernel from FIT Image at
90000000 ...
Could not find configuration node
ERROR: can't get kernel image!
Arago forked the kernel-fitimage class [1] and altered the
configuration nodes naming while adding the OPTEE support by
using FITIMAGE_CONF_BY_NAME by default [2].
The "upstream" kernel-fitimage class from openembedded-core still
add the "conf-" prefix for each configuration nodes [3].
The ITS file format (from doc/uImage.FIT/source_file_format.txt)
is not really accurate with the expected naming of these nodes.
But in practice the "conf-" prefix is widely used.
When the FIT image support has been added for ti armv7 platforms
the naming from Arago has been used [3]. Fix this issue by adding
the prefix expected by the ITS file generated by kernel-fitimage
class from openembedded-core.

tools: kwboot: Fix sending and processing debug message pattern (-d option)
-d option is currently broken. In most cases BootROM does not detect this
message pattern. For sending debug message pattern it is needed to do same
steps as for boot message pattern.
Implement sending debug message pattern via same separate thread like it is
for boot message pattern.
Checking if BootROM entered into UART debug mode is different than
detecting UART boot mode. When in boot mode, BootROM sends xmodem NAK
bytes. When in debug mode, BootROM activates console echo and reply back
every written byte (extept \r\n which is interpreted as executing command
and \b which is interpreting as removing the last sent byte).
So in kwboot, check that BootROM send back at least 4 debug message
patterns as a echo reply for debug message patterns which kwboot is sending
in the loop.
Then there is another observation, if host writes too many bytes (as
command) then BootROM command line buffer may overflow after trying to
execute such long command. To workaround this overflow, it is enough to
remove bytes from the input line buffer by sending 3 \b bytes for every
sent character. So do it.
With this change, it is possbile to enter into the UART debug mode with
kwboot -d option.

tools: kwboot: Use separate thread for sending boot message pattern
After BootROM successfully detects boot message pattern on UART it waits
until host stop sending data on UART. For example Armada 385 BootROM
requires that host does not send anything on UART at least 24 ms. If host
is still sending something then BootROM waits (possibly infinitely).
BootROM successfully detects boot message pattern if it receives it in
small period of time after power on.
So to ensure that host put BootROM into UART boot mode, host must send
continuous stream of boot message pattern with a small gap (for A385 at
least 24 ms) after series of pattern. But this gap cannot be too often or
too long to ensure that it does not cover whole BootROM time window when it
is detecting for boot message pattern.
Therefore it is needed to do following steps in cycle without any delay:
1. send series of boot message pattern over UART
2. wait until kernel transmit all data
3. sleep small period of time
At the same time, host needs to monitor input queue, data received on the
UART and checking if it contains NAK byte by which BootROM informs that
xmodem transfer is ready.
But it is not possible to wait until kernel transmit all data on UART and
at the same time in the one process to also wait for input data. This is
limitation of POSIX tty API and also by linux kernel that it does not
provide asynchronous function for waiting until all data are transmitted.
There is only synchronous variant tcdrain().
So to correctly implement this handshake on systems with linux kernel, it
is needed to use tcdrain() in separate thread.
Implement sending of boot message pattern in one thread and reading of
reply in the main thread. Use pthread library for threads.
This change makes UART booting on Armada 385 more reliable. It is possible
to start kwboot and power on board after minute and kwboot correctly put
board into UART boot mode.
Old implementation without separate thread has an issue that it read just
one byte from UART input queue and then it send 128 message pattern to the
output queue. If some noise was on UART then kwboot was not able to read
BootROM response as its input queue was just overflowed and kwboot was
sending more data than receiving.
This change basically fixed above issue too.

arm: a37xx: pci: Fix a3700_fdt_fix_pcie_regions() function again
The a3700_fdt_fix_pcie_regions() function still computes nonsense.
It computes the fixup offset from the PCI address taken from the first
row of the "ranges" array, which means that:
- PCI address must equal CPU address (otherwise the computed fix offset
will be wrong),
- the first row must contain the lowest address.
This is the case for the default device-tree, which is why we didn't
notice it.
It also adds the fixup offset to all PCI and CPU addresses, which is
wrong.
Instead:
1) The fixup offset must be computed from the CPU address, not PCI
address.
2) The fixup offset must be computed from the row containing the lowest
CPU address, which is not necessarily contained in the first row.
3) The PCI address - the address to which the PCIe controller remaps the
address space as seen from the point of view of the PCIe device -
must be fixed by the fix offset in the same way as the CPU address
only in the special case when the CPU adn PCI addresses are the same.
Same addresses means that remapping is disabled, and thus if we
change the CPU address, we need also to change the PCI address so
that the remapping is still disabled afterwards.
Consider an example:
The ranges entries contain:
PCI address CPU address
70000000 EA000000
E9000000 E9000000
EB000000 EB000000
By default CPU PCIe window is at:
E8000000 -
F0000000
Consider the case when TF-A moves it to:
F2000000 -
FA000000
Until now the function would take the PCI address of the first entry:
70000000, and the new base,
F2000000, to compute the fix offset:
F2000000 -
70000000 =
82000000, and then add 8200000 to all addresses,
resulting in
PCI address CPU address
F2000000 6C000000
6B000000 6B000000
6D000000 6D000000
which is complete nonsense - none of the CPU addresses is in the
requested window.
Now it will take the lowest CPU address, which is in second row,
E9000000, and compute the fix offset
F2000000 -
E9000000 =
09000000,
and then add it to all CPU addresses and those PCI addresses which
equal to their corresponding CPU addresses, resulting in
PCI address CPU address
70000000 F3000000
F2000000 F2000000
F4000000 F4000000
where all of the CPU addresses are in the needed window.

missing which leaves us running directly from the AHB clock, which is
set to 200MHz.

mach-sunxi: Add boot device detection for SUNIV/F1C100s
In contrast to other Allwinner SoCs the F1C100s BROM does not store a
boot source indicator in the eGON header in SRAM. This leaves the SPL
guessing where we were exactly booted from, and for instance trying
the SD card first, even though we booted from SPI flash.
By inspecting the BROM code and by experimentation, Samuel found that the
top of the BROM stack contains unique pointers for each of the boot
sources, which we can use as a boot source indicator.
This patch removes the existing board_boot_order bodge and replace it
with a proper boot source indication function.
The only caveat is that this only works in the SPL, as the SPL header
gets overwritten with the exception vectors, once U-Boot proper takes
over. Always return MMC0 as the boot source, when called from U-Boot
proper, as a placeholder for now, until we find another way.

To quote the author:
I was looking into the arm64 boot code lately and stumbled upon some
issues. Also Nishanth brought back memories of a lengthy debug session,
which was caused due to U-Boot keeping SErrors masked. As the resulting
patches are all somewhat related, I gathered this series here to address
those problems.
Patches 1 to 3 address exception handling issues, with the SError
enablement being the most prominent fix here.
Patch 4 cleans up asm/io.h. This was on the list before[1], but was
somehow lost when it was intercepted by a shorter version of itself.
Patches 5 and 6 clean up some unnecessarily complicated AArch64 assembly
code.

armv8: Fix and simplify branch_if_master/branch_if_slave
The branch_if_master macro jumps to a label if the CPU is the "master"
core, which we define as having all affinity levels set to 0. To check
for this condition, we need to mask off some bits from the MPIDR
register, then compare the remaining register value against zero.
The implementation of this was slighly broken (it preserved the upper
RES0 bits), overly complicated and hard to understand, especially since
it lacked comments. The same was true for the very similar
branch_if_slave macro.
Use a much shorter assembly sequence for those checks, use the same
masking for both macros (just negate the final branch), and put some
comments on them, to make it clear what the code does.
This allows to drop the second temporary register for branch_if_master,
so we adjust all call sites as well.
Also use the opportunity to remove a misleading comment: the macro
works fine on SoCs with multiple clusters. Judging by the commit
message, the original problem with the Juno SoC stems from the fact that
the master CPU *can* be configured to be from cluster 1, so the
assumption that the master CPU has all affinity values set to 0 does not
hold there. But this is already mentioned above in a comment, so remove
the extra comment.

armv8: Force SP_ELx stack pointer usage
In ARMv8 we have the choice between two stack pointers to use: SP_EL0 or
SP_ELx, which is banked per exception level. This choice is stored in
the SP field of PState, and can be read and set via the SPSel special
register. When the CPU takes an exception, it automatically switches to
the SP_ELx stack pointer.
Trusted Firmware enters U-Boot typically with SPSel set to 1, so we use
SP_ELx all along as our sole stack pointer, both for normal operation and
for exceptions.
But if we now for some reason enter U-Boot with SPSel cleared, we will
setup and use SP_EL0, which is fine, but leaves SP_ELx uninitialised.
When we now take an exception, we try to save the GPRs to some undefined
location, which will usually end badly.
To make sure we always have SP_ELx pointing to some memory, set SPSel
to 1 in the early boot code, to ensure safe operation at all times.

armv8: Always unmask SErrors
The ARMv8 architecture describes the "SError interrupt" as the fourth
kind of exception, next to synchronous exceptions, IRQs, and FIQs.
Those SErrors signal exceptional conditions from which the system might
not easily recover, and are normally generated by the interconnect as a
response to some bus error. A typical situation is access to a
non-existing memory address or device, but it might be deliberately
triggered by a device as well.
The SError interrupt replaces the Armv7 asynchronous abort.
Trusted Firmware enters U-Boot (BL33) typically with SErrors masked,
and we never enable them. However any SError condition still triggers
the SError interrupt, and this condition stays pending, it just won't be
handled. If now later on the Linux kernel unmasks the "A" bit in PState,
it will immediately take the exception, leading to a kernel crash.
This leaves many people scratching their head about the reason for
this, and leads to long debug sessions, possibly looking at the wrong
places (the kernel, but not U-Boot).
To avoid the situation, just unmask SErrors early in the ARMv8 boot
process, so that the U-Boot exception handlers reports them in a timely
manner. As SErrors are typically asynchronous, the register dump does
not need to point at the actual culprit, but it should happen very
shortly after the condition.
For those exceptions to be taken, we also need to route them to EL2,
if U-Boot is running in this exception level.
This removes the respective code snippet from the Freescale lowlevel
routine, as this is now handled in generic ARMv8 code.
