Given a file ../img of size 4294967296 with GPT partition table and
partitions:

=> host bind 0 ../img
=> part list host 0
Disk host-0.blk not ready

The cause is os_filesize() returning int. File sizes must use off_t.

Correct all uses of os_filesize() too.

add block storage emulation for NVM XIP flash devices

Some paltforms such as Corstone-1000 need to see NVM XIP raw flash
as a block storage device with read only capability.

Here NVM flash devices are devices with addressable
memory (e.g: QSPI NOR flash).

The implementation is generic and can be used by different platforms.

Two drivers are provided as follows.

  nvmxip-blk :

    a generic block driver allowing to read from the XIP flash

  nvmxip Uclass driver :

        When a device is described in the DT and associated with
        UCLASS_NVMXIP, the Uclass creates a block device and binds it with
	 the nvmxip-blk.

Platforms can use multiple NVM XIP devices at the same time by defining a
DT node for each one of them.

Use standard U-Boot types in the file to make the code less verbose.

The code has quite a few unnecessary brackets and comparisons to zero,
etc. Fix these up as well as some upper-case hex values and use of 0x in
printf() strings.

Avoid the use of the function name in a few of the debug() calls, since
this causes a checkpatch warning. Convert all other calls too.

Use lower-case hex consistently.

Avoid using #ifdef and use a single function declaration, so it is easier
to read.

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
value.

Drop the unnecessary blksz variable while we are here.

Fixes: 68e6f221ed0 ("block: ide: Fix block read/write with driver model")

We only use one member of the ide_dev_desc[] array at a time and it does
not stick around outside ide_probe(). Use a single element instead.

Copy over the missing members of blk_desc at the same, since this was
missing from the previous code.

Rather than having the caller fill some of this in, do it all in the
ide_ident() function, since it knows all the values.

Update ide_ident() to indicate whether it finds a device or not. Use
that to decide whether to create a block device for it, rather than
looking DEV_TYPE_UNKNOWN.
