Fix a longstanding bug where the LBA is calculated as the size of the
media instead of the number of blocks. This was perhaps not noticed
earlier since it prints the correct value first, before setting the wrong

db89e72302 ide: Move setting of vendor strings into ide_probe()
The current implementation adds this information in the block device's
probe() function, which is called in the blk_probe_or_unbind() in
ide_probe().

It is simpler to do this in ide_probe() itself, since the effect is the
same. This helps to consolidate use of ide_dev_desc[] which we would like
to remove.

Use strlcpy() to keep checkpatch happy.

646deed40b ide: Correct use of ATAPI
The use of atapi_read() was incorrect dropped. Fix this so that it will
be used when needed. Use a udevice for the first argument of atapi_read()
so it is consistent with ide_read().

This requires much of the ATAPI code to be brought out from behind the
existing #ifdef. It will still be removed by the compiler if it is not
needed.

Add an atapi flag to struct blk_desc so the information can be retained.

80778f505c ide: Move ide_init() into probing
At present the code does ide_init() as a separate operation, then calls
device_probe() to copy over the information. We can call ide_init() from
probe just as easily.

The only difference is that using 'ide init' twice will do nothing.
However it already fails to copy over the new data in that case, so the
effect is the same. For now, unbind the block devices and remove the IDE
device, which causes the bus to be probed again. Later patches will fix
this up fully, so that all blk_desc data is copied across.

Since ide_reset() is only called from ide_init(), there is no need to init
the ide_dev_desc[] array. This is already done at the end of ide_init() so
drop this code.

The call to uclass_first_device() is now within the probe() function of
the same device, so does nothing. Drop it.

Fixes IDE issues found on the Malta board under Qemu:

1) DMA implied commands were sent to the controller in stead of the PIO
variants. The rest of the code is DMA free and written for PIO operation.

2) direct pointer access was used to read and write the registers instead
of the inb/inw/outb/outw functions/macros. Registers don't have to be
memory mapped and ATA_CURR_BASE() does not have to return an offset from
address zero.

3) Endian isues in ide_ident() and reading/writing data in general. Names
were corrupted and sizes misreported.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.
