c3061ce8f1 imx8qxp_mek: Select CONFIG_NET_RANDOM_ETHADDR
Some i.MX8QXP MEK boards do not have MAC address stored
and hang during eth driver probe:

Error: ethernet@5b040000 address not set.

(Board hangs)

To fix this problem select CONFIG_NET_RANDOM_ETHADDR so that
a valid MAC address can be used in such case.

fddfe87359 tegra: fdt: Add tegra186-u-boot.dtsi
All Tegra chips except Tegra186 have a tegraNNN-u-boot.dtsi. Duplicate
Tegra210's copy of this file for Tegra186. This ensures that a /binman node
exists in U-Boot's control DT. Subsequent to 3c10dc95bd ("binman: Add a
library to access binman entries") this appears to be required. I haven't
really investigated why all this is necessary or how it works, but simply
observed the boot failure listed below, bisected it, noticed the
inconsistency in DT files, and found that fixing it resolved the boot
issue.

85eeaae3cc arm64: dts: zcu100-revC: Give wifi some time after power-on
Somewhere along recent changes to power control of the wl1831, power-on
became very unreliable on the Ultra96, failing like this:

wl1271_sdio: probe of mmc2:0001:1 failed with error -16
wl1271_sdio: probe of mmc2:0001:2 failed with error -16

After playing with some dt parameters and comparing to other users of
this chip, it turned out we need some power-on delay to make things
stable again. In contrast to those other users which define 200 ms,
Ultra96 is already happy with 10 ms.

de79ca9512 arm64: zynqmp: Add board_boot_order for MMC boot extension
In past SPL_ZYNQMP_TWO_SDHCI symbol was introduced to handle boards with
two sdhci controllers. The problem was that U-Boot is registering
controllers based on aliases in DT but bootmode targets specific controller
ID. That's why on boards with one "second" sdhci controller bootmode was
pointing to second controller(MMC2) but alias was setup to mmc0 (the first
controller). And SPL requires to point to mmc0 in this case.

Long time ago commit f101e4bd37
("spl: add support for alternative boot device") added support for handling
multiple bootmodes in SPL. Use this functionality and setup second sdhci
controller as backup boot device.

Below is table with behavior:
HW/bootmode  bootorder
sd0/sd0      mmc0/mmc1 (mmc1 never called)
sd1/sd1      mmc1/mmc0 (mmc0 fails and mmc1 is called)
sd0+sd1/sd0  mmc0/mmc1 (mmc1 never called)
sd0+sd1/sd1  mmc1/mmc0 (mmc0 never called)

All other bootmodes are not affected but order can be extended to cover
advance boot flows.

724caaba4c arm64: zynqmp: Do not call bss init and board_init_r from board_init_f
There is no reason to clear bss and call board_init_r() from board_init_f()
beca it can be called directly from crt0_64.S with also support for SPL
stack relocation to SDRAM.
For more information please take a look at arch/arm/lib/crt0_64.S

53c69dec33 board: xilinx: Add support for user configurable boot script offset
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

18be60b8bc arm64: zynqmp: Fix emmc boot mode boot_target sequence
Emmc boot devcie is mounted to mmc@ff160000 controller on zynqmp.
Detect mmc alias at run time for setting up proper boot_targets
sequence instead of setting boot_targets manually.
Removed setting "modeboot" variable as it not longer need as we
switched to distro boot.
