56c7e80155 tools: mkimage: Check if file is regular file
Current Makefile.spl passes -R parameter which is not empty
and pointing to ./ folder.
"./tools/mkimage -T zynqmpimage -R ./"" -d spl/u-boot-spl.bin
spl/boot.bin"
That's why mkimage is trying to parse ./ file and generate
register init which is wrong.
Check that passed filename is regular file. If not do not work with it.

3b6460809c tools: mkimage: Add support for initialization table for Zynq and ZynqMP
The Zynq/ZynqMP boot.bin file contains a region for register initialization
data. Filling in proper values in this table can reduce boot time
(e.g. about 50ms faster on QSPI boot) and also reduce the size of
the SPL binary.

The table is a simple text file with register+data on each line. Other
lines are simply skipped. The file can be passed to mkimage using the
"-R" parameter.

It is recommended to add reg init file to board folder.
For example:
CONFIG_BOOT_INIT_FILE="board/xilinx/zynqmp/xilinx_zynqmp_zcu102/reg.int

58ad86288f x86: Enable EFI loader support
Enable this so that EFI applications (notably grub) can be run under U-Boot
on x86 platforms.

At present the 'hello world' EFI application is not supported for the
qemu-x86_efi_payload64 board. That board builds a payload consisting of a
64-bit header and a 32-bit U-Boot, which is incompatible with the way the
EFI loader builds its EFI application. The following error is obtained:

x86_64-linux-ld.bfd: i386 architecture of input file
   `lib/efi_loader/helloworld.o' is incompatible with i386:x86-64 output

This could be corrected with additional Makefile rules. For now, this
feature is disabled for that board.

06d43c808d arm: Set TTB XN bit in case DCACHE_OFF for LPAE mode
While we setup the mmu initially we mark set_section_dcache with
DCACHE_OFF flag. In case of non-LPAE mode the DCACHE_OFF macro
is rightly defined with TTB_SECT_XN_MASK set so as to mark all the
4GB XN. In case of LPAE mode  XN(Execute-never) bit is not set with
DCACHE_OFF. Hence XN bit is not set by default for DCACHE_OFF which
keeps all the regions execute okay and this leads to random speculative
fetches in random memory regions which was eventually caught by kernel
omap-l3-noc driver.

Fix this to mark the regions as XN by default.

c19a28bc65 board: am335x/mux: Do not hang when encountering a bad EEPROM
In most cases, the SPL and u-boot.img will be on the same boot media.
Since the SPL was loaded by the boot rom, the pinmux will already have
been configured for this media. This, the board will still be able to
boot successfully, or at least reach the u-boot console, where more
recovery options are available.

I've encountered this on a beaglebone black with a corrupted EEPROM.
Removing this check allowed the board to boot successfully. I've also
seen this on EVM-based boards with an unprogrammed EEPROM. On those
boards, for some reason there were no UART messages. This made it look
as if the SOC was dead.

Remove the hang(), as it is not a fatal error. Also reformat the error
message to be clearer as to the cause. The original message made it
appear as if the wrong binary was being loaded.

When performing a cache disable function, code must not access DRAM.
That is because when the cache is disabled, it will be bypassed and all
loads and stores will be serviced by RAM. This prevents accessing any
dirty data in the cache. In turn, this means the stack cannot be
used, since that is in RAM. To guarantee that code doesn't use RAM (and
in particular the stack) __asm_flush_l3_cache() must be manually
implemented in assembly, rather than implemented in C since the compiler

2b950f3aea ARM: tegra: configure Ethernet address on Tegra186
On Tegra186, the bootloader which runs before U-Boot passes the Ethernet
MAC address to U-Boot using device tree. Extract this value and write it
to the environment, so that the Ethernet uclass picks it up and uses it
for the built-in Ethernet device.

86919a2306 ARM: tegra: add SoC-level hook for board_late_init()
Extend the Tegra186 implementation of board_late_init() to call a per-SoC
"hook" function. This will allow SoC-specific (rather than Tegra-wide)
functionality to be implemented without the core Tegra code needing to be
aware of the details. While board186.c is currently only used for
Tegra186, it should be applicable to any other future SoC, and perhaps its
simple design could be back-ported to older SoCs in the future too.

ba4dfef146 net: add driver for Synopsys Ethernet QoS device
This driver supports the Synopsys Designware Ethernet QoS (Quality of
Service) a/k/a eqos IP block, which is a different design than the HW
supported by the existing designware.c driver. The IP supports many
options for bus type, clocking/reset structure, and feature list. This
driver currently supports the specific configuration used in NVIDIA's
Tegra186 chip, but should be extensible to other combinations quite
easily, as explained in the source.
