U-Boot typically interprets unprefixed numbers as base 16, and DFU RAM
entity parsing has historically done so. Reverse the change to default
to base 10, so that values in previously working command-lines aren't

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.

The dfu_alt_info_spl variable allows passing a starting point
for the binary to be flashed in the SPI NOR.
For example, if we have 'dfu_alt_info_spl=spl raw 0x400', this means
that we want to flash the binary starting at address 0x400.
In order to do so we need to erase the entire sector and write to
the the subsequent SPI NOR sectors taking such start address
into account for the address calculations.
Tested by succesfully writing SPL binary into 0x400 offset and
the u-boot.img at offset 64 kiB of a SPL NOR.

SPI NOR flashes need to erase the entire sector size and we cannot pass
any arbitrary length for the erase operation.
To illustrate the problem:
Copying data from PC to DFU device
Download [=========================] 100% 478208 bytes
Download done.
state(7) = dfuMANIFEST, status(0) = No error condition is present
state(10) = dfuERROR, status(14) = Something went wrong, but the
device does not know what it was
Done!
In this case, the binary has 478208 bytes and the M25P32 SPI NOR
has an erase sector of 64kB.
478208 = 7 entire sectors of 64kiB + 19456 bytes.
Erasing the first seven 64 kB sectors works fine, but when trying
to erase the remainding 19456 causes problem and the board hangs.
Fix the issue by always erasing with the erase sector size.

When writing to files in a filesystem on MMC, dfu_mmc.c buffers up the
entire file content until the end of the transaction, at which point the
file is written in one go. This allows writing files larger than the USB
transfer size (CONFIG_SYS_DFU_DATA_BUF_SIZE); the maximum written file
size is CONFIG_SYS_DFU_MAX_FILE_SIZE (the size of the temporary buffer).
The current file reading code does not do any buffering, and so limits
the maximum read file size to the USB transfer size. Enhance the code to
do the same kind of buffering as the write path, so the same file size
limits apply.
Remove the size checking code from dfu_read() since all read paths now
support larger files than the USB transfer buffer.

DFU currently allocates buffer memory at the start of each data transfer
operation and frees it at the end. Especially since memalign() is used to
allocate the buffer, and various other allocations happen during the
transfer, this can expose the code to heap fragmentation, which prevents
the allocation from succeeding on subsequent transfers.
Fix the code to allocate the buffer once when DFU mode is initialized,
and free the buffer once when DFU mode is exited, to reduce the exposure
to heap fragmentation.
The failure mode is:
// Internally to memalign(), this allocates a lot more than s to guarantee
// that alignment can occur, then returns chunks of memory at the start/
// end of the allocated buffer to the heap.
p = memalign(a, s);
// Various other malloc()s occur here, some of which allocate the RAM
// immediately before/after "p".
//
// DFU transfer is complete, so buffer is released.
free(p);
// By chance, no other malloc()/free() here, in DFU at least.
//
// A new DFU transfer starts, so the buffer is allocated again.
// In theory this should succeed since we just free()d a buffer of the
// same size. However, this fails because memalign() internally attempts
// to allocate much more than "s", yet free(p) above only free()d a
// little more than "s".
p = memalign(a, s);

For writing files, DFU implementation requires the file buffer
with the len at least of file size. For big files it requires
the same big buffer.
Previously the file buffer was allocated as a static variable,
so it was a part of U-Boot .bss section. For 32MiB len of buffer
we have 32MiB of additional space, required for this section.
The .bss needs to be cleared after the relocation.
This introduces an additional boot delay at every start, but usually
the dfu feature is not required at the standard boot, so the buffer
should be allocated only if required.
This patch removes the static allocation of this buffer,
and alloc it with memalign after first call of function:
- dfu_fill_entity_mmc()
and the buffer is freed on dfu_free_entity() call.
This was tested on Trats2.
A quick test with trace. Boot time from start to main_loop() entry:
- ~888ms - before this change (arch memset enabled for .bss clear)
- ~464ms - after this change

was passed for memalign() without checking its value.
And the the memalign will return non null pointer for size 0.
This could possibly cause data abort, so now the value of var

This commit provides distinction between DFU device detach and reset.
The -R behavior is preserved with proper handling of the dfu-util's -e
switch, which detach the DFU device.
By running dfu-util -e; one can force device to finish the execution of
dfu command on target and execute some other scripted commands.
Moreover, some naming has been changed - the dfu_reset() method now is known
as dfu_detach(). New name better reflects the purpose of the code.
It was also necessary to increase the number of usb_gadget_handle_interrupts()
calls since we also must wait for detection of the USB reset event.
Example usage:
1. -e (detach) switch
dfu-util -a0 -D file1.bin;dfu-util -a3 -D uImage;dfu-util -e
access to u-boot prompt.
2. -R (reset) switch

CONFIG_SYS_DFU_DATA_BUF_SIZE may be large to allow for FAT/ext layouts

block. This prevents the DFU protocol from timing out when e.g. writing

Fix calls to dfu_write() and dfu_flush() to detect errors in the I/O
itself. This could happen due to problems with the storage medium, or
simply when trying to write a FAT/ext file that is larger than the buffer
dfu_mmc.c maintains for this purpose.
Signal the error by switching the DFU state/status. This will be picked
up by the DFU client when it sends the next DFU request. Note that errors
can't simply be returned from e.g. dnload_request_complete(), since that
function has no way to pass errors back to the DFU client; a call to
dnload_request_complete() simply means that a USB OUT completed.
This error state/status needs to be cleared when the next DFU client
connects. While there is a DFU_CLRSTATUS request, no DFU client seems to
send this. Hence, clear this when selecting the USB alternate setting on
the USB interface.
Finally, dfu.c relies on a call to dfu_flush() to clear up the internal
state of the write transaction. Now that errors in dfu_write() are
detected, dfu_flush() may no longer be called for every transaction.
Separate out the cleanup code into a new function, and call it whenever
dfu_write() fails, as well as from any call to dfu_flush().

DFU read support appears to rely upon dfu->read_medium() updating the
passed-by-reference len parameter to indicate the remaining size
available for reading.
dfu_read_medium_mmc() never does this, and the implementation of
dfu_read_medium_nand() will only work if called just once; it hard-codes
the value to the total size of the NAND device irrespective of read
offset.
I believe that overloading dfu->read_medium() is confusing. As such,
this patch introduces a new function dfu->get_medium_size() which can
be used to explicitly find out the medium size, and nothing else.
dfu_read() is modified to use this function to set the initial value for
dfu->r_left, rather than attempting to use the side-effects of
dfu->read_medium() for this purpose.
Due to this change, dfu_read() must initially set dfu->b_left to 0, since
no data has been read.
dfu_read_buffer_fill() must also be modified not to adjust dfu->r_left
when simply copying data from dfu->i_buf_start to the upload request
buffer. r_left represents the amount of data left to be read from HW.
That value is not affected by the memcpy(), but only by calls to
dfu->read_medium().
After this change, I can read from either a 4MB or 1.5MB chunk of a 4MB
eMMC boot partion with CONFIG_SYS_DFU_DATA_BUF_SIZE==1MB. Without this
change, attempting to do that would result in DFU read returning no data
at all due to r_left never being set.
