Merge tag 'u-boot-atmel-2021.10-a' of https://source.denx.de/u-boot/custodians/u-boot-atmel into next
First set of u-boot-atmel features for the 2021.10 cycle:
This feature set converts the boards pm9261 and pm9263 Ethernet support
to DM; enables hash command for all SAM boards; fixes the NAND pmecc
bit-flips correction; adds Falcon boot for sama5d3_xplained board; and
other minor adjustments.
Linux has had some stability issues when using AISRAM with a different
frequency from SRAM. Mirror their change here now that we relocate into
AISRAM.

R5 SPL needs access to cfg space of Rings and UDMAP, therefore add RING

Note that these registers are present within respective IPs but are
not populated in Linux DT nodes (as they are configured via TISCI APIs)
and hence are added to -u-boot.dtsi for now.

MCU timer1 is used as the tick timer for MCU R5 SPL, and the
clock-frequency defined in DT appears to be incorrect at the moment.
Actual clock source for the timer is MCU_SYSCLK0 / 4 which is 250MHz.
Earlier setup of 25MHz went unnoticed, as there was a separate issue
with omap-timer, which caused an error to the clock by a factor of 8
with j7 devices. This problem surfaced once the omap-timer was fixed.

Force the clk-k3 driver to probe early during R5 SPL boot to ensure the

For USB DFU boot mode there is a limitation on the load address of boot
images that they have to be less than 0x70001000. Therefore, move the
SPL_TEXT_BASE address to 0x70000000.
Currently ATF is being loaded at 0x70000000, if the SPL is being loaded at
0x70000000 then ATF would overwrite SPL image when loaded. Therefore, move
the location of ATF to a latter location in SRAM, past the SPL image. Also
rearrange the EEPROM and BSS data on top of ATF.

U-Boot either supports USB host or device mode for a node at a time in the
device tree nodes. To support both host and dfu bootmodes, dr_mode is set
to "peripheral" by default and then fixed based on the mode selected by
the boot mode config dip switches on the board.
This needs to happen before the cdns3 generic layer binds the usb device
to a host or a device driver. Therefore, use fdtdec_setup_board()
implementation to fixup the device tree property.

Current version of this function uses a lot of incorrect assumptions about

* parent(#address-cells) == 2
* #size-cells == 2
* number of entries == 2
* address size of first entry == 0x1000000
* second child address entry == base + 0x1000000
Trying to increase PCIe MEM space to more than 16 MiB leads to an overlap
with PCIe IO space, and trying to define additional MEM space (as a third
entry in the `ranges` DT property) causes U-Boot to crash when booting the
kernel.

Commit 2243d19e56 ("mmc: mmc-uclass: Use dev_seq() to read aliases

where explicitly named devices come first, then any other non-named
devices follow, without filling gaps.
For quite a while we have had an "mmc1 = &mmc2;" alias in our
sunxi-u-boot.dtsi, which now leads to the problem that the SD card
(which was always mmc device 0) now gets to be number 2.
This breaks quite some boot scripts, including our own distro boot
commands, and some other features looking at $mmc_bootdev, also
fastboot.
