mtd: mtdraw: Fix cdev size calculation for large NANDs ...

Raw size for large NAND devices (> 4 GB) can exceed 32 bits, so we need
64 bit types as factors. Both factors are of 32 bit types, as such is
the return value. At least one factor needs to be 64 bit type when
calculating the size.

of: refactor of_read_number for clarity ...

While the code is correct, less sophisticated static analyzers (and
users operating them..) trip over it, because they don't see that
the be32_to_cpu argument is evaluated multiple times only if it's
constant. Moving the side effect out:

- Lets us avoid the false positive
- Aligns us with what Linux does
- Makes the code IMO a bit clearer

Do so.

ddr: fsl: fix null pointer dereference handling DDR4 memories ...

cppcheck reports:

  drivers/ddr/fsl/util.c:42:27: error: Null pointer dereference:

Because get_memory_clk_period_ps expects a valid pointer, but is instead
passed NULL. Fix this by passing along the DDR controller handle like all
other calls to the function do. This is untested.

startup: add $global.autoboot to make behavior configurable ...

We already have a global_autoboot_state variable that controls barebox
init behavior on startup:

* ABORT      abort and fall into shell
* MENU       display boot menu
* BOOT       boot immediately, only abortable via ctrl+c
             during init
* COUNTDOWN  regular boot after count down

Exporting this as a device parameter allows us to support some
different boot scenarios:

* COUNTDOWN is the default
* ABORT boot always while debugging
* display MENU by default (e.g. for graphical boots)
* BOOT while ignoring external code calling console_countdown_abort()

startup: don't clobber original autoboot state ...

do_autoboot_countdown changes autoboot state if the user presses m for
menu or ctrl+c to abort during count down. This is an internal detail
and doesn't need to be reflected in the state of the global variable.

This will improve UX when exporting the variable in the follow-up
commit, because on a regular boot it $autoboot will expand to countdown
instead of abort/boot/menu dependent on prior user input.

ARM: dts. i.MX7: add stopgap solution for barebox UART clock breakage ...

Commit 8b2104d740 ("driver: Call of_clk_set_defaults for each probed device")
made barebox act on the assigned-clock-parents property everywhere, not
only for clock provider nodes. This breaks at least the serial console on
the i.MX7 SabreSD board; only garbage is output if the patch is not
reverted. As stopgap measure, override these properties for all enabled
uart nodes in the barebox i.MX7 device tree. This reverts the behavior
to what it was like before the offending commit.

This is of course no real solution, as obviously Linux was fine dealing
with these properties before. But this hack should at least fix the
serial console for the boards that were broken in v2020.03.0.

When a proper fix follows, this patch can be reverted.
