arm64: booti: allow to place kernel image anywhere in physical memory
At first, the ARM64 Linux booting requirement recommended that the
kernel image be placed text_offset bytes from 2MB aligned base near
the start of usable system RAM because memory below that base address
was unusable at that time.
This requirement was relaxed by Linux commit
a7f8de168ace ("arm64:
allow kernel Image to be loaded anywhere in physical memory").
Since then, the bit 3 of the flags field indicates the tolerance
of the kernel physical placement. If this bit is set, the 2MB
aligned base may be anywhere in physical memory. For details, see
Documentation/arm64/booting.txt of Linux.
The booti command should be also relaxed. If the bit 3 is set,
images->ep is respected, and the image is placed at the nearest
bootable location. Otherwise, it is relocated to the start of the
system RAM to keep the original behavior.
Another wrinkle we need to take care of is the unknown endianness of
text_offset for a kernel older than commit
a2c1d73b94ed (i.e. v3.16).
We can detect this based on the image_size field. If the field is
zero, just use a fixed offset 0x80000.

This causes early run-time failures in all boards compiled using the Thumb-1

usb: gadget: g_dnl: fix g_dnl_set_serialnumber()
instead of only copying if strlen(s) is less than 32 characters, let's
just copy at most 31 characters regardless of the size of
serial#. This will guarantee that we always have a serial number if
serial# environment variable is set to anything.
Note that without a proper serial number, USB Command Verifier fails
our test of Device Descriptor since we will claim to have a serial
number without really providing one when requested.
