fs: tftp: Use pr_debug for errors ...

This has been debug output before for good reasons. The users will
usually print the error messages when they want to.

fs: tftp: improve file size handling ...

Previously we used FILE_SIZE_STREAM unconditionally. Instead, fill the
inode size with a valid filesize if we have one and only if not fall
back to FILE_SIZE_STREAM.

fs: tftp: hide files which are actually not present on the server ...

In tftp_lookup we claimed that every desired file is there. This leads
to problems when a user only tests if a file is present and makes
decisions upon this information. Rather than claiming that all files
are present do a tftp_do_open() on the files and see if it is really
there.

fs: tftp: fix return value ...

When tftp_get_inode() fails it is a sign for a out of memory situtation
rather than an indicator for no space left on the filesystem, so return
-ENOMEM.

fs: tftp: fix memory hole ...

dpath() returns a pointer to an allocated string, so we have to free it.
Put the pointer into our file private data and free it on close time.

fs: tftp: overhaul debugging ...

- use pr_* instead of debug()
- use pr_vdebug for the less interesting messages
- use pr_err for error messages
- print state as clear text and not as number

commands: of_property: copy value instead of resizing ...

Commit 748d1b8 adds the fixup feature to the above command. With this commit an
unwanted free(data) on the freshly set property value is done if someone tries
to set the value of an already present property (not the case for a new
property). Furthermore in fixup mode the pointer fixup->data is freed when the
fixup function is called more than once. This leads to a hanging system after
calling of_dump -F many times.
Fix this issues by copying the data to a new allocated memory area like a new
property is created.

ARM: MMU: fix wrong dma_flush_range in arm_create_pte() ...

Since 7ba0f2d299 arm_create_pte() flushes the page table entries itself
and it's no longer done in arch_remap_range(). Unfortunately it does
not flush the modified 1st level page table entry, but instead the base
of the page table. Fix it up.

Fixes: 7ba0f2d299 ARM: mmu: fix cache flushing when replacing a section with a PTE

serial: lpuart: Avoid division by zero when requested baudrate is ...

With serdev device support added there's now a corner case where:

 1. There is a DT node for a serdev device on one of the UARTs
 2. There is no driver that binds against serdev device's compatibility
    string

with 1 and 2 being true it is possible to end up in a situation where
a particualr UART has not been initalized to any baudrate when
clock_notifier_call_chain() gets called. This effectively translates
to

	set_baudrate(uart, 0);

which for LPUART driver result in a division by zero.

To avoid this problem, convert lpuart_serial_setbaudrate() to treat
zero baudrate as a request to disable the UART. While we are at it add
a BUG_ON() to lpuart_setbrg() to simplify finding any future bugs.

ARM: i.MX: boot: Rework boot source detection for i.MX7 and i.MX8MQ ...

For both SoCs data found in SBMR registers reflects only the boot
source that was selected via pins of fuses and not the final boot
source that ended up being used by MaskROM code. Original i.MX7 boot
source detection implementation worked around that fact by having a
special code to correctly handle "Manufacturing Mode".

MaskROM in i.MX8MQ changed what SoC uses as recovery device and
switched it to be USDHC2. It also made recovery device switch always
enabled. Since correct actual boot source detection is important to
being able to properly boot i.MX8MQ (due to not using DCD to
initialize RAM), change the code to handle described exception.

Instead of trying to adapt original i.MX7 code with yet another
special case if(), change the whole thing to do what U-Boot does on
i.MX7 and i.MX8MQ and use "Boot information for software" provided by
recent (found in i.MX7 and i.MX8MQ) versions of MaskROM.
