part: Drop duplication declaration of block_dev_desc_t

2016-01-25T15:39:46+00:00

This is already defined in ide.h, which part.h includes. So we don't need
the duplicate typedef. At least with my old blackfin gcc 4.3.5 tool chain,
this causes an error.

mmc: store hwpart in the block device

2016-01-14T02:05:19+00:00

This will allow us to have multiple block device structs each referring
to the same eMMC device, yet different HW partitions.

For now, there is still a single block device per eMMC device. As before,
this block device always accesses whichever HW partition was most recently
selected. Clients wishing to make use of multiple block devices referring
to different HW partitions can simply take a copy of this block device
once it points at the correct HW partition, and use each one as they wish.
This feature will be used by the next patch.

In the future, perhaps get_device() could be enhanced to return a
dynamically allocated block device struct, to avoid the client needing to
copy it in order to maintain multiple block devices. However, this would
require all users to be updated to free those block device structs at some
point, which is rather a large change.

Most callers of mmc_switch_part() wish to permanently switch the default
MMC block device's HW partition. Enhance mmc_switch_part() so that it does
this. This removes the need for callers to do this. However,
common/env_mmc.c needs to save and restore the current HW partition. Make
it do this more explicitly.

Replace use of mmc_switch_part() with mmc_select_hwpart() in order to
remove duplicate code that skips the call if that HW partition is already
selected.

block: pass block dev not num to read/write/erase()

2016-01-14T02:05:18+00:00

This will allow the implementation to make use of data in the block_dev
structure beyond the base device number. This will be useful so that eMMC
block devices can encompass the HW partition ID rather than treating this
out-of-band. Equally, the existence of the priv field is crying out for
this patch to exist.

gpt: part: Definition and declaration of GPT verification functions

2015-11-23T16:01:50+00:00

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.

sandbox: block driver using host file/device as backing store

2014-01-09T00:24:03+00:00

Provide a way to use any host file or device as a block device in U-Boot.
This can be used to provide filesystem access within U-Boot to an ext2
image file on the host, for example.

The support is plumbed into the filesystem and partition interfaces.

We don't want to print a message in the driver every time we find a missing
device. Pass the information back to the caller where a message can be printed
if desired.
