029bb91e80 arm: mvebu: turris_{omnia, mox}: ensure running bootcmd_rescue always works
One of the points of putting the rescue boot command into default
environment is that user can invoke it without physical access to the
board (without having to press the factory reset button), by running
  run bootcmd_rescue
in U-Boot's console.

Therefore we have to ensure that bootcmd_rescue is always set to default
value, regardless of whether the factory reset button was pressed.
Otherwise the variable will be empty for example after upgrade from
previous U-Boot.

Fixes: 176c3e7760 ("arm: mvebu: turris_omnia: support invoking rescue boot from console")

6bb577dbb3 arm64: zynqmp: Disable EFI_CAPSULE_ON_DISK_EARLY
Sata/scsi and usb based devices are not started at this stage that's why
disks are not found and early update can't happen.
It is because of deficiency in the UEFI implementation which is not able to
deal with block devices which are added or removed after initialization.

EFI capsule on disk early feature needs to be fixed first to be able to
enable this feature properly.

0008d80866 fs/squashfs: fix reading of fragmented files
The fragmented files were not correctly read because of two issues:

- The squashfs_file_info struct has a field named 'comp', which tells if
the file's fragment is compressed or not. This field was always set to
'true' in sqfs_get_regfile_info and sqfs_get_lregfile_info. It should
actually take sqfs_frag_lookup's return value. This patch addresses
these two assignments.

- In sqfs_read, the fragments (compressed or not) were copied to the
output buffer through a for loop which was reading data at the wrong
offset. Replace these loops by equivalent calls to memcpy, with the
right parameters.

I tested this patch by comparing the MD5 checksum of a few fragmented
files with the respective md5sum output in sandbox, considering both
compressed and uncompressed fragments.

dcd2bbe051 usb: dwc2: Avoid delay when initializing USB peripheral by dwc2
When `usb start` is called on the terminal, the dwc2 driver will try
to start every USB device as host first, even if it is explicitly
configured as peripheral in the device tree (dr_mode = "peripheral").

So to avoid an unwanted 15 seconds delay when initializing the usb
(one second per channel = 1s x 15), this patch adds a check to the
initialization, and will skip host initialization of the device is
explicitly set as peripheral. The checking is already done similarly
in the `drivers/usb/gadget/dwc2_udc_otg.c` driver.

139eaa7a2b of: addr: Translate 'dma-ranges' for parent nodes missing 'dma-ranges'
'dma-ranges' frequently exists without parent nodes having 'dma-ranges'.
While this is an error for 'ranges', this is fine because DMA capable
devices always have a translatable DMA address. Also, with no
'dma-ranges' at all, the assumption is that DMA addresses are 1:1 with
no restrictions unless perhaps the device itself has implicit
restrictions.

This keeps in sync with Linux kernel commit:

176c3e7760 arm: mvebu: turris_omnia: support invoking rescue boot from console
Make it possible to invoke rescue boot from U-Boot console, without
having to press the factory reset button. This is needed when accessing
the device remotely, for example.

Achieve this by putting rescue command into `bootcmd_rescue` default
environment variable and setting some distroboot environment variables
to their default values when the factory button is pressed.

Rescue boot from console can be invoked by running
  run bootcmd_rescue

b321722f22 arm: a37xx: pci: Fix configuring PCIe resources
The `ranges` DT property of the PCIe node is currently ignored by
Aardvark driver - all entries are used as transparent PCIe MEM, despite
some of them being defined for IO in DT.

This is because the driver does not setup PCIe outbound windows and thus
a default configuration is used.

This can cause an external abort on CPU when a device driver tries to
access non-MEM space.

Setup the PCIe windows according to the `ranges` property for all
non-MEM resources (currently only IO) and also non-transparent MEM
resources.

Because Linux expects that bootloader does not setup Aardvark PCIe
windows, disable them before booting Linux.

079b35a261 arm: a37xx: pci: Increase PCIe MEM size from 16 MiB to 127 MiB
For some configurations with more PCIe cards and PCIe bridges, 16 MiB of
PCIe MEM space may not be enough. Since TF-A already allocates a 128 MiB
CPU window for PCIe, and since IO port space is only 64 KiB in total,
use all the remaining space (64 + 32 + 16 + 8 + 4 + 2 + 1 = 127 MiB) for
PCIe MEM.

4a82fca8e3 arm: a37xx: pci: Fix a3700_fdt_fix_pcie_regions() function
Current version of this function uses a lot of incorrect assumptions about
the `ranges` DT property:

 * 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.

  ## Flattened Device Tree blob at 04f00000
     Booting using the fdt blob at 0x4f00000
     Loading Device Tree to 000000001fb01000, end 000000001fb08f12 ... OK
  ERROR: board-specific fdt fixup failed: <unknown error>
   - must RESET the board to recover.

Fix a3700_fdt_fix_pcie_regions() to properly parse and update all addresses
in the `ranges` property according to
https://elinux.org/Device_Tree_Usage#PCI_Address_Translation

Now it is possible to increase PCIe MEM space from 16 MiB to maximal value
of 127 MiB.
