dereference str_disk_guid to be sure that malloc worked. In
cmd/nvedit.c we need to be careful that we can also fit in that leading
space when adding to the string. And in tools/fit_image.c we need to
re-work the error handling slightly in fit_import_data() so that we only
call munmap() once. We have two error paths here, one where we have an
fd to close and one where we do not. Adjust labels to match this.

The previous commit fixed a problem in FAT code where going back to the

Add a test to exercise this case (which was once fixed in commit
18a10d46f2 "fat: handle paths that include ../" but reintroduced due to
the directory iterator refactoring).
This test only very barely catches the problem - without the fix the
size command still gives valid output but the additional spurious
"Invalid FAT entry" error message makes it not get caught in the
'egrep -A3 ' output. I tried to make a proper test that grows the root
directory to two clusters lots of with dummy files but that causes the
write tests to crash the sandbox totally...

Currently we can only test FAT32 which is the default FAT version that
mkfs.vfat creates by default. Instead make it explicitly create either a
FAT16 or a FAT32 volume. This allows us to exercise more code, for
instance the root directory handling is done differently in FAT32 than
the older FATs.
Adding FAT12 support is a much bigger job since the test creates a 2.5GB
file and the FAT12 maximum partition size is way smaller than that.

This board builds an U-Boot binary that is bootable with QEMU's 'virt'
machine on ARM. The minimal QEMU command line is:
qemu-system-arm -machine virt,highmem=off -bios u-boot.bin
(Note that the 'highmem=off' parameter to the 'virt' machine is required for
PCI to work in U-Boot.) This command line enables the following:
- u-boot.bin loaded and executing in the emulated flash at address 0x0
- A generated device tree blob placed at the start of RAM
- A freely configurable amount of RAM, described by the DTB
- A PL011 serial port, discoverable via the DTB
- An ARMv7 architected timer
- PSCI for rebooting the system
- A generic ECAM-based PCI host controller, discoverable via the DTB
Additionally, QEMU allows plugging a bunch of useful peripherals to the PCI bus.
The following ones are supported by both U-Boot and Linux:
- To add a Serial ATA disk via an Intel ICH9 AHCI controller, pass e.g.:
-drive if=none,file=disk.img,id=mydisk -device ich9-ahci,id=ahci -device ide-drive,drive=mydisk,bus=ahci.0
- To add an Intel E1000 network adapter, pass e.g.:
-net nic,model=e1000 -net user
- To add an EHCI-compliant USB host controller, pass e.g.:
-device usb-ehci,id=ehci
- To add a NVMe disk, pass e.g.:
-drive if=none,file=disk.img,id=mydisk -device nvme,drive=mydisk,serial=foo
