disk: part: Enable get_info pointer for CONFIG_SPL_FAT_SUPPORT

2016-04-12T00:48:24+00:00

The patch "dm: part: Convert partition API use to linker lists"
(sha1: 96e5b03c8ab749b6547f6a3ceb4d4b9f274211aa) is adding new
dependency for enabling SPL_EXT_SUPPORT to be able to get
information about DOS partition.
get_info is also required for FAT support only which is used on Xilinx
Zynq boards.

disk/part.c: Expose list of available block drivers

2016-03-15T19:19:22+00:00

We have a pretty nice and generic interface to ask for a specific block
device. However, that one is still based around the magic notion that
we know the driver name.

In order to be able to write fully generic disk access code, expose the
currently internal list to other source files so that they can scan through
all available block drivers.

dm: part: Rename some partition functions

2016-03-14T21:34:50+00:00

Rename three partition functions so that they start with part_. This makes
it clear what they relate to.

dm: part: Convert partition API use to linker lists

2016-03-14T21:34:50+00:00

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.

dm: blk: Rename get_device_and_partition()

2016-03-14T21:34:50+00:00

Rename this function to blk_get_device_part_str(). This is a better name
because it makes it clear that the function returns a block device and
parses a string.

dm: blk: Rename get_device() to blk_get_device_by_str()

2016-03-14T21:34:50+00:00

The current name is too generic. The function returns a block device based
on a provided string. Rename it to aid searching and make its purpose
clearer. Also add a few comments.

dm: Add a new header for block devices

2016-03-14T21:34:50+00:00

At present block devices are tied up with partitions. But not all block
devices have partitions within them. They are in fact separate concepts.

Create a separate blk.h header file for block devices.
