bd897a0789 ARM: zynq: Add Z-turn board V5
Adding Z-turn board V5 to resolve the change between:

"Z-TURNBOARD_schematic.pdf" schematics state version 1 to 4 has Atheros AR8035
"Z-Turn_Board_sch_V15_20160303.pdf" schematics state version 5 has Micrel KSZ9031

At this time the S25FL128SAGNFI003 doesn't work because of bug:

*** Warning - spi_flash_probe_bus_cs() failed, using default environment

zynq-zturn was checked on V5 board, same error.

Maybe Z-turn board have the same problem (board with W25Q128BVFIG).

29bd8ada52 fpga: kconfig: Rename SPL_FPGA_SUPPORT to SPL_FPGA
The patch does sed 's/SPL_FPGA_SUPPORT/SPL_FPGA/g' but also fixing Makefile
and zynqmp.c to simplify if/endif logic in zynqmp.c.

This change is mostly done to be able to use CONFIG_IS_ENABLED macro and
obj-$(CONFIG_$(SPL_)FPGA) in Makefile. For them symbols need to be in sync.

And removing one line from Topic Miami boards which is not needed because
symbol is not enabled via Kconfig.

e2572b5544 xilinx: common: Do not save fdt_blob to bss section
For SPL flow without specifying address for DT loading DTB is automatically
appended behind U-Boot code. Specifically _end symbol is used. Just behind
it there is place for bss section.
It means if early code is using static variable and there is a write to
this variable DTB file is corrupted if variable is located between DTB
start and end.
In this particular case offset of this variable from bss section start is
very small (0x40) that's why DT is currupted which breaks this boot flow.

fa793165da xilinx: zynqmp: refactor silicon name function
Current algorithm used to get the silicon name is bit complicated and
hard to follow. Updated to use more straightforward mechanism based on
the Device ID code table (Table 1-2). The full IDCODE register is used
(except device revision bits [31:28]) to get the device name and IDCODE2
value is used for identifying the variant.

Additionally to make the algorithm bit more clear it also save some space
as the devices table is slightly bit smaller.

1a005b4ae4 board: xilinx: Enable changing default DTB pick up address
U-Boot on xilinx boards is checking one address where DTB can be placed as
the first location for DTB. Originally this code was developed for Versal
where QEMU was putting generated DTB for U-Boot to use.
The patch enables changing this address which is necessary for cases where
default address is pointing to location (DDR) which is not present. The
access to this location can cause exception.

Linux kernel for arm32 requires dtb and initrd to be placed in low memory
to work properly. This requirement is described in chapter 4b) and 5) in
Linux documentation (Documentation/arm/booting.rst).

There is an issue on arm32 with 2GB of memory that bootm_size is bigger
than Linux lowmem (for example with VMSPLIT_3G). That's why limit bootm
size on these systems not to be above 768MB.

1b208d59ba arm64: zynqmp: Fix set_fdtfile() not to break u-boots DTB
Origin function was calling strsep which replaced delimiter ',' by a null
byte ('\0'). Operation was done directly on FDT which ends up with the
following behavior:

ZynqMP>  printenv fdtfile
fdtfile=xilinx/zynqmp.dtb
ZynqMP> fdt addr $fdtcontroladdr
ZynqMP> fdt print / compatible
compatible = "xlnx", "zynqmp"

As is visible fdtfile was correctly composed but a null byte caused that
xlnx was separated from zynqmp.
This hasn't been spotted because in all Xilinx DTs there are at least 3
compatible string and only the first one was affected by this issue.
But for systems which only had one compatible string "xlnx,zynqmp" it was
causing an issue when U-Boot's DT was used by Linux kernel.

The patch removes strsep calling and strchr is called instead which just
locate the first char after deliminator ',' (variable called "name").
And using this pointer in fdtfile composing.

Fixes: 91d7e0c47f ("arm64: zynqmp: Create fdtfile from compatible string")

env_get_bootm_size() and env_get_bootm_low() without specifying bootm_low
and bootm_size variables are taking by default gd->bd->bi_dram[0].start and
gd->bd->bi_dram[0].size. As you see 0 means bank 0 which doesn't need to be
PS ddr and even can be memory above 39bit VA which is what U-Boot supports
now.
That's why setup bootm variables based on ram_base/ram_size setting to make
sure that boot images are placed to the same location as U-Boot is placed.
This location should be by default location where OS can boot from.

e20d88bffa xilinx: zynqmp: Enable pmufw config reloading
PMU FW has functionality to accept and reload configuration object at run
time. The patch is adding support for doing it via u-boot prompt.

For example:
tftpboot 100000 pmu_obj.bin
zynqmp pmufw 100000 $filesize

The most of pmufw configurations don't allow config reloading.
Also official Xilinx PMUFW doens't support this feature properly but the
patch should open a way to call PMUFW with this request.

Here is example of PMUFW config fragment which enables config reloading.

/* SET CONFIG SECTION */
PM_CONFIG_SET_CONFIG_SECTION_ID,        /* Section ID */
PM_CONFIG_IPI_PSU_CORTEXA53_0_MASK | PM_CONFIG_IPI_PSU_CORTEXR5_0_MASK |

39c5cf0e70 topic: zynqmp: Add support for zynqmp-xilinx-xdp platform
XDP - Xilinx Drone Platform is a board for drones or other UAV.

Pinmux the SD card by default, and if the SD card detect line is high
(inactive) then pinmux the SD1 interface to EMIO instead. SD is placed on
extension card and shares connection with on board wife. That means that
when SD card is present in the board wifi can't be used.

There seems to be an issue with DDR access from PL at 2400MT/s, after
updating the PMU and ATF firmware this is causing extremely slow DDR
access. Reducing the DDR speed from 2400 to 2133 appears to solve that
issue, even though the hardware has proven to be 2400 capable.

dfbe492ede board: zynqmp: Fix for wrong AMS setting by ROM
A bug in the ZynqMP bootrom sets the PS_SYSMON_ANALOG_BUS register
at 0xFFA50914 to the wrong value 0x3201. This causes the AMS to
exchange the PS supply voltages 0 and 1. On Xilinx boards this is
not noticeable since these are tied together, it's only really
noticeable if banks 500 and 501 have different supplies. Xilinx' tech
support reported this undocumented register to be the cause, and
this patch applies a fix for all boards by programming the correct
value.

Currently "script_offset_f" env variable is hardcoded, this variable
specifies from which offset of the flash boot.scr should be read/write.
As flashes are of different sizes having a fixed offset makes it
difficult to load other images into the flash which may overwrite the
boot script or cannot utilize the full memory. This current fix
creates a new config "CONFIG_BOOT_SCRIPT_OFFSET" which holds the
offset address, overwrites the "script_offset_f" variable.
Also removed existing variable with default values, as the default
values are held by CONFIG_BOOT_SCRIPT_OFFSET

  ./board/xilinx/zynqmp/xil_io.h:22:6: warning: symbol 'usleep' was not declared. Should it be static?

Also add __maybe_unused to usleep() since it is not used by minimized
psu_init_gpl.c files, so it would warn as "defined but not used".

c28a9cfa40 arm64: zynqmp: spl: install a PMU firmware config object at runtime
Optionally allow U-Boot to load a configuration object into the Power
Management Unit (PMU) firmware on Xilinx ZynqMP.

The configuration object is required by the PMU FW to enable most SoC
peripherals. So far the only way to boot using U-Boot SPL was to hard-code
the configuration object in the PMU firmware. Allow a different boot
process, where the PMU FW is equal for any ZynqMP chip and its
configuration is passed at runtime by U-Boot SPL.

All the code for Inter-processor communication with the PMU is isolated in
a new file (pmu_ipc.c). The code is inspired by the same feature as
implemented in the Xilinx First Stage Bootloader (FSBL) and Arm Trusted
Firmware:

 * fb647e6b4c/lib/sw_apps/zynqmp_fsbl/src/xfsbl_misc_drivers.c (L295)
 * c48d02bade/plat/xilinx/zynqmp/pm_service/pm_api_sys.c (L357)

SPL logs on the console before loading the configuration object:

  U-Boot SPL 2019.07-rc1-00511-gaec224515c87 (May 15 2019 - 08:43:41 +0200)

06985289d4 watchdog: Implement generic watchdog_reset() version
This patch tries to implement a generic watchdog_reset() function that
can be used by all boards that want to service the watchdog device in
U-Boot. This watchdog servicing is enabled via CONFIG_WATCHDOG.

Without this approach, new boards or platforms needed to implement a
board specific version of this functionality, mostly copy'ing the same
code over and over again into their board or platforms code base.

With this new generic function, the scattered other functions are now
removed to be replaced by the generic one. The new version also enables
the configuration of the watchdog timeout via the DT "timeout-sec"
property (if enabled via CONFIG_OF_CONTROL).

This patch also adds a new flag to the GD flags, to flag that the
watchdog is ready to use and adds the pointer to the watchdog device
to the GD. This enables us to remove the global "watchdog_dev"
variable, which was prone to cause problems because of its potentially
very early use in watchdog_reset(), even before the BSS is cleared.

ccd063e981 watchdog: Move watchdog_dev to data section (BSS may not be cleared)
This patch moves all instances of static "watchdog_dev" declarations to
the "data" section. This may be needed, as the BSS may not be cleared
in the early U-Boot phase, where watchdog_reset() is already beeing

"!watchdog_dev" in watchdog_reset() may not be true and the function
may continue to run.

The same change as was done for zynqmp with this description:

Add support for enabling the first watchdog pointed via aliases.

DT fragment:
	aliases {
		...
		watchdog0= &watchdog0;
		watchdog1 = &watchdog_lpd;
		...

<zynqmp example removed>

Till this patch the first watchdog found in DT was used and started
which is not enabling all possible configuration based on user request.

6da4f67ad0 arm/arm64: zynq/zynqmp: pass the PS init file as a kconfig variable
U-Boot needs to link ps7_init_gpl.c on Zynq or psu_init_gpl.c on
ZynqMP (PS init for short). The current logic to locate this file for
both platforms is:

 1. if a board-specific file exists in
    board/xilinx/zynq[mp]/$(CONFIG_DEFAULT_DEVICE_TREE)/ps?_init_gpl.c
    then use it
 2. otherwise use board/xilinx/zynq/ps?_init_gpl.c

In the latter case the file does not exist in the U-Boot sources and
must be copied in the source tree from the outside before starting the
build. This is typical when it is generated from Xilinx tools while
developing a custom hardware. However making sure that a
board-specific file is _not_ found (and used) requires some trickery
such as removing or overwriting all PS init files (e.g.: the current
meta-xilinx yocto layer).

This generates a few problems:

 * if the source tree is shared among different out-of-tree builds,
   they will pollute (and potentially corrupt) each other
 * the source tree cannot be read-only
 * any buildsystem must add a command to copy the PS init file binary
 * overwriting or deleting files in the source tree is ugly as hell

Simplify usage by allowing to pass the path to the desired PS init
file in kconfig variable XILINX_PS_INIT_FILE. It can be an absolute
path or relative to $(srctree). If the variable is set, the
user-specified file will always be used without being copied
around. If the the variable is left empty, for backward compatibility
fall back to the old behaviour.

Since the issue is the same for Zynq and ZynqMP, add one kconfig
variable in a common place and use it for both.

Also use the new kconfig help text to document all the ways to give
U-Boot the PS init file.

Build-tested with all combinations of:
 - platform: zynq or zynqmp
 - PS init file: from XILINX_PS_INIT_FILE (absolute, relative path,
   non-existing), in-tree board-specific, in board/xilinx/zynq[mp]/
 - building in-tree, in subdir, in other directory

2882b39d56 arm64: zynqmp: Setup the first boot_target at run time
Detect mmc alias at run time for setting up proper boot_targets sequence.
The first target has to correspond with boot mode.

The purpose of this patch is to get rid of CONFIG_ZYNQ_SDHCI0/1
parameters in full U-Boot.
Unfortunately this patch can't remove it because there is missing
mmc implementation for SPL_DM_SEQ_ALIAS.

Also xilinx_zynqmp.h only setup boot commands for mmc0 and mmc1.
It means using aliases with higher number won't work. But switching
between mmc0 and mmc1 should work properly.

1d6c54ecb3 arm: zynqmp: Add ZynqMP minimal R5 support
Xilinx ZynqMP also contains dual Cortex R5 which can run U-Boot.
This patch is adding minimal support to get U-Boot boot.
U-Boot on R5 runs out of DDR with default configuration that's why
DDR needs to be partitioned if there is something else running on arm64.
Console is done via Cadence uart driver and the first Cadence Triple
Timer Counter is used for time.

This configuration with uart1 was tested on zcu100-revC.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

generate new_targets env accordingly. Performing strlen on
null address causes it to fail with exception if isolation
is enabled with DDR address zero as secure. It works with out
isolation enabled as zero is valid address but it may lead to
junk values in boot_targets.
This patch fixes the issue by checking return value of env_get
so that it generate boot_targets properly.

de9bf1b591 ARM: zynq: Replace board specific with generic memory bank decoding
The dram_init and dram_init_banksize functions were using a board
specific implementation for decoding the memory banks from the fdt. This
board specific implementation uses a static variable 'tmp' which makes
these functions unsafe for execution from within the board_init_f
context.

This unsafe use of a static variable was causing a specific bug when
using the zynq_zybo configuration, U-Boot would generate the following
error during image load. This was caused due to dram_init overwriting
the relocations for the 'image' variable within the do_bootm function.
Out of coincidence the un-initialized memory has a compression type
which is the same as the value for the relocation type R_ARM_RELATIVE.

   Uncompressing Invalid Image ... Unimplemented compression type 23

It should be noted that this is just one way the issue could surface,
other cases my not be observed in normal boot flow. Depending on the
size of various sections, and location of relocations within __rel_dyn
and the compiler/linker the outcome of this bug can differ greatly.

This change makes the dram_init* functions use a generic implementation
of decoding and populating memory bank and size data.

The dram_init* functions for the zynq board are not safe for use from
the board_init_f stage due to its use of the 'tmp' static variable.

This incorrect use of a static variable was causing rare issues where
the dram_init function would overwrite some parts the __rel_dyn section
which caused obscure failures.

Using the zynq_zybo configuration, U-Boot would generate the following
error during image load. This was caused due to dram_init overwriting
the relocations for the "image" variable within the do_bootm function.

It should be noted that this is just one way the issue could surface,

This change removes the existing code and copies the implementation of
the dram_init and dram_init_banksize from the
arch/arm/mach-uniphier/dram_init.c source. This version of these
functions does not use static variables and behaves the same (reading
banks from fdt, and using the first bank as the ram_size).

d58fc12eb7 ARM64: zynqmp: Add support for DFU from SPL
SPL needs to have bigger stack size because of USB.
Simple malloc needs to be disabled because dfu code requires different
allocation functions. There is no space in OCM that's why random place
in DDR is used.

BOOTD must be disabled because it is causing compilation error.

All variables are disabled and used only variables valid for DFU because
they are simple huge. Including automatic variables added by
CONFIG_ENV_VARS_UBOOT_CONFIG.
Hardcode addresses for u-boot, atf, kernel and dtb
just for SPL DFU code.

Enable SPL DFU for zcu100.
Create new usb_dfu_spl variable just to run Linux kernel loaded in SPL.

b72894f14d ARM64: zynqmp: Add support for standard distro boot commands
Nand and QSPI are not defined now but this will be extended.
Based on selected bootmode boot_targets are rewritten.
Patch also contains detection if variables are saved. If yes don't
rewrite boot_targets variable.

Also move variable setup to the end of file because SCSI needs to be
defined before others macros are using it.
