At the moment, writing large amounts of data to the eMMC causes the device
to freeze. The symptoms vary, sometimes the device reboots immediately,
but usually it will just get stuck.

It turns out that the issue is not actually related to the eMMC:
Apparently, Samsung has made some modifications to the TrustZone firmware.
These require additional memory which is reserved at 0x85500000-0x86000000.
The downstream kernel describes this memory reservation as:

/* Additionally Reserved 6MB for TIMA and Increased the TZ app size
 * by 2MB [total 8 MB ]
 */

This suggests that it is used for additional TZ apps, although the extra
memory is actually 11 MB instead of the 8 MB mentioned in the comment.

Writing to the protected memory causes the kernel to crash or freeze.
In our case, writing to the eMMC causes the disk cache to fill
the available RAM, until the kernel eventually crashes
when attempting to use the reserved memory.

Add the additional memory as reserved-memory to fix this problem.

Pull new zonefs file system from Damien Le Moal:
 "Zonefs is a very simple file system exposing each zone of a zoned
  block device as a file.

  Unlike a regular file system with native zoned block device support
  (e.g. f2fs or the on-going btrfs effort), zonefs does not hide the
  sequential write constraint of zoned block devices to the user. As a
  result, zonefs is not a POSIX compliant file system. Its goal is to
  simplify the implementation of zoned block devices support in
  applications by replacing raw block device file accesses with a richer
  file based API, avoiding relying on direct block device file ioctls
  which may be more obscure to developers.

  One example of this approach is the implementation of LSM
  (log-structured merge) tree structures (such as used in RocksDB and
  LevelDB) on zoned block devices by allowing SSTables to be stored in a
  zone file similarly to a regular file system rather than as a range of
  sectors of a zoned device. The introduction of the higher level
  construct "one file is one zone" can help reducing the amount of
  changes needed in the application while at the same time allowing the
  use of zoned block devices with various programming languages other
  than C.

  Zonefs IO management implementation uses the new iomap generic code.
  Zonefs has been successfully tested using a functional test suite
  (available with zonefs userland format tool on github) and a prototype
  implementation of LevelDB on top of zonefs"

In order to allow the GICv4 code to link properly on 32bit ARM,
make sure we don't use 64bit divisions when it isn't strictly
necessary.
