25484d9070 xilinx: common: Fix boot script address
Currently u-boot supports addresses upto 39-bits only. If anybody
wants to use addresses of more than 39-bits in Linux they will have
a separate memory node in DT. In such cases they will have multiple
memory nodes.
Currently u-boot selects and runs on lower memory bank region.
But bootscript is being loaded on dram bank 0, where dram bank 0 will
point to 1st memory node in DT. If first memory node is mentioned as
higher ddr(>39-bits address) then u-boot cannot load the bootscript.
So fix this issue by setting bootscript address within the lower memory
bank region.

ef1be3e364 xilinx: zynqmp: Add usb dfu/thor distro boot support
In usb boot mode distro boot should select usb device as primary boot
device instead of usb host. So make usb dfu as primary boot device. But do
not list it in boot_targets as fallback option because it is not classic
mode for booting. Using 60s timeout by default should be enough time for
dfu-utils to start transaction. In case none needs this please change
timeout value in the command or disable CONFIG_DFU_TIMEOUT.

35b65dd8ef reset: Remove addr parameter from reset_cpu()
Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to.  This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value.  Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.

Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g.  COLD vs WARM resets).  As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).

To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely.  Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.

This transformation was done with the following coccinelle patch:

    @@
    expression argvalue;
    @@
    - reset_cpu(argvalue)
    + reset_cpu()

    @@
    identifier argname;
    type argtype;
    @@
    - reset_cpu(argtype argname)
    + reset_cpu(void)

d388cedd46 xilinx: Add DDR base address to bootscript address
Add ram base address to scriptaddr env variable to make boot
script address to be a valid address when ddr base address changes.

This works properly if the first memory region is the region where uboot
runs. Also the solution was taken in respect of a lot of jtag script
putting u-boot script to certain address. For standard cases
bd->bi_dram[0].start is 0 all the time. Only for systems with DDR placed
out of this location it does calculation.

This is not the best solution and should be done differently in future but
enough for now till we don't have full solution ready yet.

As of now, it supports only common header and board area of FRU. Also, it

There is no reason to have ZYNQ specific Kconfig macro in generic location

location to be visible only for us.
Also introduce new bool entry ZYNQ_MAC_IN_EEPROM to have also an option to
disable it or enable. This has connection to code which is reading the

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.

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.

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.

not noticeable since these are tied together, it's only really
noticeable if banks 500 and 501 have different supplies. Xilinx' tech

Correct the PL bitstream loading sequence for zynqaes command by

bitstream using the zynq aes command. This was done by setting

This patch fixes the issue of loading the encrypted PL bitstream

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

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.

ec48b6c991 arm64: versal: Add support for new Xilinx Versal ACAPs
Xilinx is introducing Versal, an adaptive compute acceleration platform
(ACAP), built on 7nm FinFET process technology. Versal ACAPs combine
Scalar Processing Engines, Adaptable Hardware Engines, and Intelligent
Engines with leading-edge memory and interfacing technologies to deliver
powerful heterogeneous acceleration for any application. The Versal AI
Core series has five devices, offering 128 to 400 AI Engines. The series
includes dual-core Arm Cortex™-A72 application processors, dual-core Arm
Cortex-R5 real-time processors, 256KB of on-chip memory with ECC, more
than 1,900 DSP engines optimized for high-precision floating point with
low latency.

The patch is adding necessary infrastructure in place without enabling
platform which is done in separate patch.

4a69366967 microblaze: Convert generic platform to DM gpio
Converting GPIO to DM requires to do changes in reset subsystem
that's why support for Microblaze soft reset via sysreset and GPIO
sysreset support was added.
These two patches enables enabling GPIO DM.
Microblaze soft reset is bind at last reset method.

GPIO reset is handled via sysreset with adding this fragment to DT.

gpio-restart {
	compatible = "gpio-restart";
	gpios = <&reset_gpio 0 0 0>;
	/* 3rd cell ACTIVE_HIGH = 0, ACTIVE_LOW = 1 */
};

hard-reset-gpio property is not documented and also handled.
Conversion is required.

Unfortunately do_reset is required for SPL that's why use only soft
microblaze reset for now.

501fc50a29 arm: zynq: Try to enable the first watchdog via aliases
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.

Add support for enabling the first watchdog pointed via aliases.

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

dm tree fragment for above configuration with patch applied:
ZynqMP> dm tree
 Class    index  Probed  Driver      Name
-----------------------------------------
...
 watchdog    0  [   ]   cdns_wdt    |   |-- watchdog@ff150000
 watchdog    1  [ + ]   cdns_wdt    |   `-- watchdog@fd4d0000
...

dm uclass fragment:
ZynqMP> dm uclass
...
uclass 75: watchdog
0   watchdog@ff150000 @ 7df02f40, seq -1, (req 1)
1 * watchdog@fd4d0000 @ 7df02ff0, seq 0, (req 0)
...

It is visible that index 1 is IP with seq 0 which means that FPD
watchdog (@fd4d0000) is in DT below LPD watchdog (@ff150000).

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