part: call part_init() in blk_get_device_by_str() only for MMC

2021-12-18T11:05:19+00:00

In blk_get_device_by_str(), the comment says: "Updates the partition table
for the specified hw partition."
Since hw partition is supported only on MMC, it makes no sense to do so
for other devices.

efi: Add uclass for devices provided by UEFI firmware

2021-12-09T19:43:25+00:00

UCLASS_EFI_LOADER is used for devices created by applications and
drivers loaded by U-Boots UEFI implementation.

This patch provides a new uclass (UCLASS_EFI_MEDIA) to be used for devices
that provided by a UEFI firmware calling U-Boot as an EFI application.

If the two uclasses can be unified, is left to future redesign.

part: return -ENOSYS when get_info not valid.

In some case, get_info() interface can be NULL, add this check to stop
from crash.

global: Convert simple_strtoul() with hex to hextoul()

2021-08-02T17:32:14+00:00

It is a pain to have to specify the value 16 in each call. Add a new
hextoul() function and update the code to use it.

Add a proper comment to simple_strtoul() while we are here.

part: Add check for NULL dev_part_str

2021-05-26T21:26:07+00:00

Some callers (e.g. cmd/fs.c) of fs_set_blk_dev may use a NULL dev_part_str.
While blk_get_device_part_str handles this fine,
part_get_info_by_dev_and_name does not. This fixes commands crashing when
implicitly using bootdevice.

The unit test has also been updated to set bootdevice to a known value and
to restore it after we are done.

Fixes: 7194527b6a ("cmd: fs: Use part_get_info_by_dev_and_name_or_num to parse partitions")

part: Fix bogus return from part_get_info_by_dev_and_name

2021-04-22T18:09:45+00:00

blk_get_device_by_str returns the device number on success. So we must
check if the return was negative to determine an error.

part: Support string block devices in part_get_info_by_dev_and_name

2021-02-26T14:30:55+00:00

This adds support for things like "#partname" and "0.1#partname". The block
device parsing is done like in blk_get_device_part_str.

This adds an option to part_get_info_by_dev_and_name_or_num to allow
callers to specify whether whole-disk partitions are fine.

part: Give several functions more useful return values

2021-02-26T14:30:55+00:00

Several functions in disk/part.c just return -1 on error. This makes them
return different errnos for different failures. This helps callers
differentiate between failures, even if they cannot read stdout.

disk: part: sandbox support in dev_print()

2021-01-30T21:25:42+00:00

Commands like 'fatinfo' call dev_print() to print device information. If
the block device is created via 'host bind', we should print accurate
information.
