blk: Make blk_next_free_devnum() public

2018-11-14T17:16:27+00:00

blk_next_free_devnum() can be helpful in some cases. Make it
a public API.

blk: Call part_init() in the post_probe() method

2018-11-14T17:16:27+00:00

part_init() is currently called in every DM BLK driver, either
in its bind() or probe() method. However we can use the BLK
uclass driver's post_probe() method to do it automatically.

Update all DM BLK drivers to adopt this change.

sandbox: blk: Switch to use platdata_auto_alloc_size for the driver data

2018-11-14T17:16:27+00:00

Currently the sandbox block driver uses priv_auto_alloc_size for
the driver data, however that's only available after the device
probe phase. In order to make it accessible in an earlier phase,
switch to use platdata_auto_alloc_size instead.

This patch is the prerequisite for the follow up patch of DM BLK
driver changes to work with Sandbox.

blk: Support block drivers in TPL

2018-10-09T10:40:27+00:00

At present it is not possible to enable/disable block drivers in TPL. This
is needed to provide sandbox support. Add a Kconfig option and adjust the
Makefile.

block: Add SPL_BLOCK_CACHE and default n

2018-06-18T18:43:13+00:00

When enabling BLOCK_CACHE on devices with limited RAM during SPL,
some devices may not boot.  This creates an option to enable
block caching in SPL by defaults off.  It is dependent on SPL_BLK

block: Have BLOCK_CACHE default to y in some cases

2018-06-07T13:12:26+00:00

When dealing with filesystems that come from block devices we can get a
noticeable performance gain in some use cases from having the block
cache enabled.  The code paths are valid in other cases when we have BLK
set and may provide wins in raw reads in some use cases, so have this be
default when BLK is enabled.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.
