dfu: Disable default calculation of CRC32

2014-06-11T00:31:48+00:00

Patch (SHA1: bd694244db7bc969954)
dfu: Introduction of the "dfu_hash_algo" env variable for checksum method
setting

already introduced more generic handling of the crc32 calculation.
Up till now the CRC32 of received data was calculated unconditionally.
This patch changes this and from now - by default the crc32 is NOT
calculated anymore.

dfu: Introduction of the "dfu_hash_algo" env variable for checksum method setting

2014-06-01T17:18:00+00:00

Up till now the CRC32 of received data was calculated unconditionally.
The standard crc32 implementation causes long delay when large images
were uploaded.

The "dfu_hash_algo" environment variable gives the opportunity to
disable on demand the hash (crc32) calculation.
It can be done without the need to recompile the u-boot binary.

By default the crc32 is calculated, which means that legacy behavior
has been preserved.

Tests results:
400 MiB ums.img file
With 		crc32 calculation: 65 sec [avg 6.29 MB/s]
Without 		crc32 calculation: 25 sec [avg 16.17 MB/s]

dfu: mmc: Provide support for eMMC boot partition access

2014-05-14T22:24:24+00:00

Before this patch it was only possible to access the default eMMC HW
partition. By partition selection I mean the access to eMMC via the
ext_csd[179] register programming.

It sometimes happens that it is necessary to write to other partitions.
This patch adds extra attribute to "raw" sub type of the dfu_alt_info
environment variable (e.g. boot-mmc.bin raw 0x0 0x200 mmcpart 1;)

It saves the original boot value and restores it after storing the file.

drivers:dfu: dfu_flush(): add raw data flush to complete dfu write

2014-05-14T22:23:56+00:00

Before dfu write and flush operations separation,
dfu write data was flushed by host download request
with len of zero size.

Since above change manually calling dfu write with zero
size has non sense (e.g. in THOR). This should be done by
flush operation.
So now dfu_write_buffer_drain() is called in dfu_flush().
If there is any raw data to flush (like it can be in thor)
then it will be physically written to medium.

dfu, nand: add medium specific polltimeout function

2014-05-08T08:38:30+00:00

add a possibility to add a medium specific polltimeout
function. So it is possible to define different
poll timeouts.

Used on nand medium, for setting the DFU_MANIFEST_POLL_TIMEOUT
only on nand ubi partitions, which is currently the only
usecase.

dfu: mmc: change offset base handling

2014-05-05T06:20:56+00:00

Previously offsets handled by dfu_fill_entity_mmc(), defined in boards'
CONFIG_DFU_ALT were treated as hexadecimal regardless of their prefix,
which sometimes led to confusion. This patch forces usage of explicit
numerical base prefixes.

dfu: mmc: raw data write fix

2014-05-05T06:00:28+00:00

When user attempted to perform a raw write using DFU (vide
dfu_fill_entity_mmc) with MMC interface not initialized before,
get_mmc_blk_size() reported invalid (zero) block size - it wasn't
possible to write ie. a new u-boot image.

This commit fixes that by initializing MMC device before use in
dfu_fill_entity_mmc().

While fixing initialization sequence, I had to change about half of
dfu_fill_entity_mmc's body, so I refactored it on the way to make it,
IMHO, considerably more comprehensible.

Being left as dead code, get_mmc_blk_size() was removed.

Tested on Samsung Goni.

dfu: mmc: Replace calls to u-boot commands with native mmc API

2014-03-23T01:20:10+00:00

For some time we have been using the run_command() with properly crafted
string. Such approach turned to be unreliable and error prone.

Switch to "native" mmc subsystem API would allow better type checking and
shall improve speed.

Also, it seems that this API is changing less often than u-boot commands.
The approach similar to env operations on the eMMC has been reused.
