28f0014bde iso: Fix part info command

let's also start counting at 1.

e40cf34a29 drivers: block: add block device cache
Add a block device cache to speed up repeated reads of block devices by
various filesystems.

This small amount of cache can dramatically speed up filesystem
operations by skipping repeated reads of common areas of a block
device (typically directory structures).

This has shown to have some benefit on FAT filesystem operations of
loading a kernel and RAM disk, but more dramatic benefits on ext4
filesystems when the kernel and/or RAM disk are spread across
multiple extent header structures as described in commit fc0fc50.

The cache is implemented through a minimal list (block_cache) maintained
in most-recently-used order and count of the current number of entries
(cache_count). It uses a maximum block count setting to prevent copies
of large block reads and an upper bound on the number of cached areas.

The maximum number of entries in the cache defaults to 32 and the maximum
number of blocks per cache entry has a default of 2, which has shown to
produce the best results on testing of ext4 and FAT filesystems.

The 'blkcache' command (enabled through CONFIG_CMD_BLOCK_CACHE) allows
changing these values and can be used to tune for a particular filesystem
layout.

96e5b03c8a dm: part: Convert partition API use to linker lists
We can use linker lists instead of explicitly declaring each function.
This makes the code shorter by avoiding switch() statements and lots of
header file declarations.

While this does clean up the code it introduces a few code issues with SPL.
SPL never needs to print partition information since this all happens from
commands. SPL mostly doesn't need to obtain information about a partition
either, except in a few cases. Add these cases so that the code will be
dropped from each partition driver when not needed. This avoids code bloat.

I think this is still a win, since it is not a bad thing to be explicit
about which features are used in SPL. But others may like to weigh in.

99e7fc8a26 mmc: emmc and hw partitions partition table id bugfix.
On bootup the emmc's hw partition is always set to 0 and the partition
table is read from it. When switching to another hw partition the
partition table's id is not updated but instead the old one from
hw partition 0 is used. If there is no partition table on hw partition 0
then the code will terminate and return error even if the desired hw
partition contains a perfectly fine partition table. This fix updates
the partition table struct to correspond to the specified hw partition
before testing if the partition table is valid or not.

> part list mmc 0 -bootable devplist

> printenv devplist

devplist=2

Then the distro scripts will search extlinux in partition 2
and not in the first partition.

cef68bf904 gpt: part: Definition and declaration of GPT verification functions
This commit provides definition and declaration of GPT verification
functions - namely gpt_verify_headers() and gpt_verify_partitions().
The former is used to only check CRC32 of GPT's header and PTEs.
The latter examines each partition entry and compare attributes such as:
name, start offset and size with ones provided at '$partitions' env
variable.

b349abbfe9 gpt: Fix the protective MBR partition size
According to the UEFI Spec (Table 16, section 5.2.3 of the version 2.4 Errata
B), the protective MBR partition record size must be set to the size of the
disk minus one, in LBAs.

However, the current code was setting the size as the total number of LBAs on
the disk, resulting in an off-by-one error.

This confused the AM335x ROM code, and will probably confuse other tools as
well.
