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).

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.

There is an issue on arm32 with 2GB of memory that bootm_size is bigger

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

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
