include: bitops: fix dead increment in fls() and ffs() ...

Static analyzers trip over this dead increment. It arguably
doesn't improve readability, so just drop the dead code.

include: <asm-generic/atomic.h>: remove stub IRQ save/restore ...

For an architecture to use <asm-generic/atomic.h>, it must define
local_irq_save() and local_irq_restore(). Instead of having every
platform define duplicate their stub definition, just drop them
altogether, so <asm-generic/atomic.h> can be used freestanding.

With fastboot over ethernet we now can have two instances of fastboot
running in parallel. Make sure that both instances use a different
temporary file to store data so that they do not influence each other.

fastboot: split generic code from USB gadget ...

The fastboot specification describes other protocols beyond USB. Allow
these to reuse the generic parts of the existing fastboot code when they
are implemented.

Most of the changes in common/fastboot.c are due to the renaming of struct
f_fastboot *f_fb to struct fastboot *fb.

.gitignore: drop stale ignore pattern include/asm ...

In old days, Linux created a symlink include/asm -> include/asm-*,
but all the asm headers were moved to arch/*/include/asm, which
is the same for Barebox too.

usb: i.MX: Add i.MX28 support ...

common.h: move the generic IOMEM definition to asm-generic/io.h ...

arch/mips/include/asm/io.h defines arch-specific IOMEM().

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.

iopoll: Introduce read_poll_timeout ...

barebox adoption of Linux commit:

| commit 5f5323a
| Author: Dejin Zheng <zhengdejin5@gmail.com>
| Date:   Mon Mar 23 23:05:51 2020 +0800
|
|     iopoll: introduce read_poll_timeout macro
|
|     this macro is an extension of readx_poll_timeout macro. the accessor
|     function op just supports only one parameter in the readx_poll_timeout
|     macro, but this macro can supports multiple variable parameters for
|     it. so functions like phy_read(struct phy_device *phydev, u32 regnum)
|     and phy_read_mmd(struct phy_device *phydev, int devad, u32 regnum) can
|     also use this poll timeout core. and also expand it can sleep some time
|     before read operation.
