<content type='text'>
The return value of write_sparse_chunk_raw is unsigned, so the existing
check has no effect. Use IS_ERR_VALUE to detect error instead, which is
what write_sparse_chunk_raw does itself.

After some header file cleanups to add missing include files, remove
common.h from all files in the lib directory. This primarily means just
dropping the line but in a few cases we need to add in other header
files now.

genimage create android-sparse file with CRC32 chunk at end. When
U-Boot's fastboot receives this chunk it returns error message:
`Fail Bogus chunk size for chunk type Dont Care`

According to reference implementation of Android's sparse file format:

&lt;https://android.googlesource.com/platform/system/core/+/refs/heads/main/
libsparse/output_file.cpp#513&gt;

the chunk_header.total_sz is CHUNK_HEADER_LEN + 4 (CRC32 size).

Commit 62649165cb02 ("lib: sparse: Make CHUNK_TYPE_RAW buffer aligned")
fixed cache alignment for systems with a D-CACHE.

However it introduced some performance regressions [1] on system
flashing huge images, such as Android.

On AM62x SK EVM, we also observe such performance penalty:
Sending sparse 'super' 1/2 (768793 KB)             OKAY [ 23.954s]
Writing 'super'                                    OKAY [ 75.926s]
Sending sparse 'super' 2/2 (629819 KB)             OKAY [ 19.641s]
Writing 'super'                                    OKAY [ 62.849s]
Finished. Total time: 182.474s

The reason for this is that we use an arbitrary small buffer
(info-&gt;blksz * 100) for transferring.

Fix it by using a bigger buffer (info-&gt;blksz * FASTBOOT_MAX_BLK_WRITE)
as suggested in the original's patch review [2].

With this patch, performance impact is mitigated:
Sending sparse 'super' 1/2 (768793 KB)             OKAY [ 23.912s]
Writing 'super'                                    OKAY [ 15.780s]

If a chunk was larger than 4GiB, then chunk_data_sz would overflow and
blkcnt would not be calculated correctly. Upgrade it to a u64 and cast
its multiplicands as well. Also fix bytes_written while we're at it.

Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.

Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

Introduce CONFIG_IMAGE_SPARSE and CONFIG_CMD_MMC_SWRITE so the "mmc
swrite" command is separated from the fastboot code.

Move image-sparse from common to lib so it's clear it's library code.

Rename CONFIG_FASTBOOT_FLASH_FILLBUF_SIZE to CONFIG_IMAGE_SPARSE_FILLBUF_SIZE
and migrate it to Kconfig.
