The test and info callbacks into the partition callback struct are
used by the "part list" command on the command line. That command
is used by the distro script.
With verb=1 set, "part list" thus throws a lot of warnings about
partitions it can't find when an upper layer searches for partitions.
So let's reduce verbosity to bring it to the same level of noise
as the other partition targets.

Since commit ff98cb90514d ("part: extract MBR signature from partitions")
SPL boot on i.MX6 starts to fail:
U-Boot SPL 2017.09-00221-g0d6ab32 (Oct 02 2017 - 15:13:19)
Trying to boot from MMC1
(keep in loop)
Use the original allocation scheme for the SPL case, so that MX6 boards
can boot again.
This is a temporary solution to avoid the boot regression.

U-Boot widely uses error() as a bit noisier variant of printf().
This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:
# define __compiletime_error(message) __attribute__((error(message)))
This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux. (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)
Let's convert error() into now treewide-available pr_err().
Done with the help of Coccinelle, excluing tools/ directory.
The semantic patch I used is as follows:
// <smpl>
@@@@
-error
+pr_err
(...)
// </smpl>

The UEFI spec allows an EFI system partition (ESP, with the bootloader or
kernel EFI apps on it) to reside on a disk using a "legacy" MBR
partitioning scheme.
But in contrast to actual legacy disks the ESP is not marked as
"bootable" using bit 7 in byte 0 of the legacy partition entry, but is
instead using partition *type* 0xef (in contrast to 0x0b or 0x0c for a
normal FAT partition). The EFI spec isn't 100% clear on this, but it even
seems to discourage the use of the bootable flag for ESPs.
Also it seems that some EFI implementations (EDK2?) even seem to ignore
partitions marked as bootable (probably since they believe they contain
legacy boot code).
The Debian installer [1] (*not* mini.iso), for instance, contains such an
MBR, where none of the two partitions are marked bootable, but the ESP
has clearly type 0xef.
Now U-Boot cannot find the ESP on such a disk (USB flash drive) and
fails to load the EFI grub and thus the installer.
Since it all boils down to the distro bootcmds eventually calling
"part list -bootable" to find potential boot partitions, it seems logical
to just add this "partition type is 0xef" condition to the is_bootable()
implementation.
This allows the bog standard arm64 Debian-testing installer to boot from
an USB pen drive on Allwinner A64 boards (Pine64, BananaPi-M64).
(Ubuntu and other distribution installers don't have a legacy MBR, so
U-Boot falls back to El Torito there).

Needed to support efi file protocol. The fallback.efi loader wants
to be able to read the contents of the /EFI directory to find an OS
to boot.
Modelled after POSIX opendir()/readdir()/closedir(). Unlike the other
fs APIs, this is stateful (ie. state is held in the FS_DIR "directory
stream"), to avoid re-traversing of the directory structure at each
step. The directory stream must be released with closedir() when it
is no longer needed.

The current code checks that no partitions overlap with the GPT partition
table using the offset of the first LBA usable for that partition.
This works fine, unless you have a partition entry that is further away
than it usually is and you want to create partitions in the gap between the
GPT header and the GPT partition entries, for example to reflash a
bootloader that needs to be set there.
Rework the test to something a bit smarter that checks whether a partition
would overlap with either the GPT header or the partition entries, no
matter where it is on the disk.
Partitions that do not have a start LBA specified will still start at the
first LBA usable set in the GPT header, to avoid weird behaviours.

Some architectures require their SPL loader at a fixed address within
the first 16KB of the disk. To avoid an overlap with the partition
entries of the EFI partition table, the first safe offset (in bytes,
from the start of the device) for the entries can be set through
CONFIG_EFI_PARTITION_ENTRIES_OFF (via Kconfig)
When formatting a device with an EFI partition table, we may need to
leave a gap between the GPT header (always in LBA 1) and the partition
entries. The GPT header already contains a field to specify the
on-disk location, which has so far always been set to LBA 2. With this
change, a configurable offset will be translated into a LBA address
indicating where to put the entries.
Now also allows an override via device-tree using a config-node (see
doc/device-tree-bindings/config.txt for documentation).
Tested (exporting an internal MMC formatted with this) against Linux,
MacOS X and Windows.

So far partition search by name has been supported only on the EFI partition
table. This patch extends the search to all partition tables.
Rename part_get_info_efi_by_name() to part_get_info_by_name(), move it from
part_efi.c into part.c and make it a generic function which traverses all part
drivers and searches all partitions (in the order given by the linked list).
For this a new variable struct part_driver.max_entries is added, which limits
the number of partitions searched. For EFI this was GPT_ENTRY_NUMBERS.
Similarly the limit is defined for DOS, ISO, MAC and AMIGA partition tables.
