Signed-off-by: NCornelia Huck <cornelia.huck@de.ibm.com>

Because of El Torito spec flaw boot image size needs to be verified.

Boot catalog entry size field has 16-bit width, and specifies size
in 512-byte units.

Thus, boot image size cannot exceed 32M.

We actually search for the file to get the file size.

This is done by scanning the ISO directory tree for the ISO block number
and reading the file size from the directory entry.

Some gcc versions (e.g. Fedora 22 gcc 5.1.1) seem to use floating

The current U-Boot binary in QEMU has a bug where it fails to support
dynamic CCSR addressing. Without this support, u-boot can not boot the
ppce500 machine anymore. This has been fixed upstream in u-boot commit
e834975b.

Update the u-boot blob we carry in QEMU to the latest u-boot upstream,
so that we can successfully run u-boot with the ppce500 machine again.

Starting with version 4.9, GCC assumes it can't safely dereference null
pointers, and uses this for some optimizations. On s390, the lowcore
memory is located at address 0, so this assumption is wrong and breaks
the s390-ccw firmware. Pass -fdelete-null-pointer-checks to avoid that.
