05737f3585 imx: update i.MX8MQ device trees
This updates the i.MX8MQ device trees and, necessarily, also the
i.MX8MQ clock bindings.  These are taken verbatim from from the
Linux kernel version v5.4-rc2, which three small changes which
were already part of the previous device tree:

 * Keep the PSCI reserved memory range
 * Keep the alias for ethernet, so that the MAC address can be set
 * Keep the modified #include for the IOMUXC pins

This commit adds falcon boot support (by also copying args necessary for

After this change it is possible to use the falcon boot in the same way
as on NAND memories. The necessary configs (i.e. CONFIG_CMD_SPL_NOR_OFS)
are now defined in Kconfig.

e0fe3dcbd0 ARM: imx: Decouple mccmon6's SPL and u-boot proper code
The mccmon6 has been used a "mixed" approach between SPL and
U-Boot proper sources.

This commit decoupes SPL and u-boot proper, which allows clear
distinction between those two code bases and facilitates

ceea0c145d watchdog: imx: Add DT ext-reset handling
The Linux imx2_wdt driver uses a fsl,ext-reset-output boolean in the
device tree to specify whether the board design should use the external
reset instead of the internal reset. Use this boolean to determine which
mode to use rather than using external reset unconditionally.

For the legacy non-DM mode, the external reset is always used in order
to maintain the previous behavior.

b4a2cdc13e arm: mxs: Increase VDDD voltage to match specification
According to IMX28CEC rev. 4, 10/2018, Table 15. Recommended Operating
Conditions, page 16, the VDDD should be set to 1.55V when the CPU is
operating at 454MHz. This is the case in U-Boot, hence increase the
VDDD voltage. This fixes instability when performing TFTP transfers.
Increase the brownout threshold to 1.4V. The documentation recommends
1.45V setting for the brownout, however, this triggers failure during
power block init, so keep the brownout slightly lower.

12e288a8ba mkimage: Set correct FDT type and ramdisk architecture in FIT auto mode

the type of fdt subimage is the same as of the main kernel image and
the architecture of the initramfs image is not set. Such an image is
refused by U-Boot when booting. This commits sets the mentioned

9b3fbb2b43 tiny-printf: Support vsnprintf()
Add a simple implementation of this function, to allow logging to be
enabled in the SPL or TPL for systems that rely on the tiny printf()
implementation.

To keep the code size small,

- The function is built only when logging is enabled, as it
  (currently) is not needed otherwise; and
- Like the existing implementation of snprintf(), its buffer-size
  parameter is ignored.

f279e1d916 lib: errno: avoid error format-overflow
In cmd/regulator.c an error occurs with GCC 9.2.1 if CONFIG_ERRNO_STR is
not defined:

cmd/regulator.c: In function ‘failure’:
cmd/regulator.c:20:2: error: ‘%s’ directive argument is null
[-Werror=format-overflow=]
   20 |  printf("Error: %d (%s)\n", ret, errno_str(ret));
      |  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In function ‘constraint’,
    inlined from ‘constraint’ at cmd/regulator.c:111:12:
cmd/regulator.c:115:3: error: ‘%s’ directive argument is null
[-Werror=format-overflow=]
  115 |   printf(" %s (err: %d)\n", errno_str(val), val);
      |   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

errno_str() should return a valid string instead of NULL if
CONFIG_ERRNO_STR is not defined.

34856b0f1c disk: part_dos: correctly detect DOS PBR
The signature 0x55 0xAA in bytes 510 and 511 of the first sector can either
indicate a DOS partition table of the first sector of a FAT file system.

The current code tries to check if the partition table is valid by looking
at the boot indicator of the partition entries. But first of all it does
not count from 0 to 3 but only from 0 to 2. And second it misses to
increment the pointer for the partition entry.

If it is a FAT file system can be discovered by looking for the text 'FAT'
at offset 0x36 or 'FAT32' at offset 0x52. In a DOS PBR there are no
partition entries, so those bytes are undefined. Don't require the byte at
offset 0x1BE to differ from 0x00 and 0x80.

With the patch the logic is changed as follows:

If the partition table has either an invalid boot flag for any partition or
has no partition at all, check if the first sector is a DOS PBR by looking
at the FAT* signature.

2f83481dff nvme: use page-aligned buffer for identify command
Change the stack-allocated buffer for the identification command
to explicitly allocate page-aligned buffers.  Even though the spec
seems to allow having admin queue commands on non page-aligned
buffers, it seems to not be possible on my i.MX8MQ board with a
a Silicon Power P34A80.  Since all of the NVMe drivers I have seen
always do admin commands on a page-aligned buffer, which does work
on my system, it makes sense for us to do that as well.
