7514fd3447 xilinx: Disable CONFIG_EFI_LOADER_BOUNCE_BUFFER for ZynqMP/Versal
Both SOCs shouldn't have any problem with 64bit dma accesses. Also with PIE
enabled when u-boot is placed above 4GB without any memory mapped below 4GB
address space efi_memory_init() call is failing due to missing memory node.

For this two reason disable this option for ZynqMP and Versal.

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.

Additionally to make the algorithm bit more clear it also save some space

592ac77342 configs: xilinx: Enable configs required for ubifs
Enable required configs for using ubifs in uboot.

UBIFS testing procedure from u-boot:
Let's say we have two partitions in dt as below and want to format
partition1 "images" with ubifs.

	partition@0 {
		label = "boot";
		reg = <0x0 0x1000000>;
	};

	partition@1 {
		label = "images";
		reg = <0x1000000 0x7000000>;
	};

We will format the partition from linux and copy some files and access
from uboot later.
First thing, in linux config disable CONFIG_MTD_SPI_NOR_USE_4K_SECTORS.
this is required as ubifs expects min LEB size as 15*1024 bytes.

Use below commands in linux to format "images" partition with ubifs.

ubiformat /dev/mtd1
ubiattach /dev/ubi_ctrl -m 1
ubimkvol /dev/ubi0 -N images -m
mount -t ubifs ubi0:images /mnt

We can copy files to /mnt and unmount it.

To access this ubifs partition from uboot, run below commands.
(Don't forget to probe device before, e.g. sf probe 0 0 0)

setenv mtdids "nor0=nor0"
setenv mtdparts "mtdparts=nor0:16m(boot),112m(images)"
ubi part images
ubifsmount ubi0:images

make sure we match "mtdparts" to whatever is given in dt w.r.t partition
sizes.

"mtdparts" command will list the mtd partitions in u-boot.

Once ubifs is mounted, we can use "ubifsls" to list the files in that
partition and use "ubifsload <addr> <filename>" to load files from ubifs
partition to DDR.

Reading information about mtd layout from DT is not supported.

bd25f9a69f mips: dts: Fix PIC32MZDA GPIO register definitions
The GPIO bank name for banks J and K are not correct when using the
'gpio' command from the console.

The driver derives the bank name from the device tree instance string by
using the instance value and adding 'A': gpio0@xxaddrxx is Bank A,
gpio1@yyaddryy is Bank B and so on.

On the PIC32, there is no Bank I so instances 8 and 9 need to be
incremented as a minimum change.

An alternative (less opaque) implementation would be to use a bank-name
property instead but this would require modifying the driver code too.

81b543a4e6 mips: dts: Fix PIC32MZDA GPIO register definitions
GPIO state cannot be changed via the device tree (e.g. with gpio-hog) or
using the 'gpio' command from the console.

The root cause is a discrepancy between the driver and the device tree:
the driver code expects an absolute I/O address in the <reg> property,
while the device tree defines the address relative to a declaration in
the parent pinctrl node.

Changing the device tree to fix a driver issue would normally be wrong,
however:
- I have run the first version of U-Boot in which this driver appears
  (v2016.03) and the same problem exists, so this is not a regression;
- There is no code that references a parent device tree node that might
  suggest the intent of the author was to parse the DT as it exists now;
- The equivalent Linux PIC32 GPIO driver also uses absolute addresses
  for the GPIO <reg> property. This change brings the U-Boot DT more
  into line with Linux.

Additionally, the data sheet (Microchip ref. 60001361H) shows that the
register set to control a GPIO bank spans 0xE0 bytes, but the device
tree specified size is only 0x48 bytes.

e5b35f706d log: mute messages generated by log drivers
When a message is written by a log driver (e.g. via the network stack) this
may result in the generation of further messages. We cannot allow these
additional messages to be emitted as this might result in an infinite
recursion.

Up to now only the syslog driver was safeguarded. We should safeguard all
log drivers instead.

01d89e3d12 dm: add cells_count parameter in live DT APIs of_parse_phandle_with_args
In the live tree API ofnode_parse_phandle_with_args, the cell_count
argument must be used when cells_name is NULL.

But this argument is not provided to the live DT function
of_parse_phandle_with_args even it is provided to
fdtdec_parse_phandle_with_args.

This patch adds support of the cells_count parameter in dev_ and
of_node API to allow migration and support of live DT:
- of_parse_phandle_with_args

3e15c315f9 optee: add property no-map to secure reserved memory
OP-TEE reserved memory node must set property "no-map" to prevent
Linux kernel from mapping secure memory unless what non-secure world
speculative accesses of the CPU can violate the memory firmware
configuration.

Add a test to verify that the no-map property is added in reserved-memory
node when fdtdec_add_reserved_memory() no-map parameter is set to true.

ccaa5747bd fdtdec: optionally add property no-map to created reserved memory node
Add boolean input argument @no_map to helper function
fdtdec_add_reserved_memory() to add or not "no-map" property
for an added reserved memory node.

Property no-map is used by the Linux kernel to not not map memory
in its static memory mapping. It is needed for example for the|
consistency of system non-cached memory and to prevent speculative
accesses to some firewalled memory.

No functional change. A later change will update to OPTEE library to
add no-map property to OP-TEE reserved memory nodes.
