1e5eca7d42 usb: return 0 from usb_stor_get_info even if removable media
This fixes a regression caused by

commit 07b2b78ce4
    dm: usb: Convert USB storage to use driver-model for block devs

which caused part_init to be called when it was not previously.
Without this patch, the following happens when a USB sd card reader is used.

=> usb start
starting USB...
USB0:   Port not available.
USB1:   USB EHCI 1.00
scanning bus 1 for devices... 3 USB Device(s) found
       scanning usb for storage devices... Device NOT ready
   Request Sense returned 02 3A 00
 ### ERROR ### Please RESET the board ###

This happens because dev_desc->blksz is 0.

ff8fef5666 Fix block device accesses beyond 2TiB
With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type,
which is required to represent block numbers for storage devices that
exceed 2TiB (the block size usually is 512B), e.g. recent hard drives.

For some obscure reason, the current U-Boot code uses lbaint_t for the
number of blocks to read (a rather optimistic estimation of how RAM
sizes will evolve), but not for the starting address. Trying to access
blocks beyond the 2TiB boundary will simply wrap around and read a
block within the 0..2TiB range.

We now use lbaint_t for block start addresses, too. This required
changes to all block drivers as the signature of block_read(),
block_write() and block_erase() in block_dev_desc_t changed.

usb_storage wouldn't compile when the CONFIG_SYS_64BIT_LBA option is
turned on because the used fixed size data types in their exported
functions when they should have used lbaint_t for the block count
parameter. That meant that when the sizes happened to be the same, when
using a 28 bit LBA, the driver would build, but when it wasn't, a 48 bit
LBA, things broke.

This change adjusts the signatures to use the right type and makes small

Fix EHCI "out of buffer pointers" with CD-ROM' introduce a bug in
usb_storage as it wrongly assumes that every transfer can use
4096 bytes per qt_buffer. This is wrong if the start address of
the data is not page aligned to 4096 bytes and leads to 'EHCI
timed out on TD' messages because of 'out of buffer pointers'
in ehci_td_buffer function.

The bug appears during load of a fragmented file and
read from or write to an unaligned memory address.

f57661394a USB: Align buffers at cacheline
This avoids cache-alignment warnings shown in console
when a usb command is entered.

Whenever X bytes of unaligned buffer is invalidated, arm core
invalidates X + Y bytes as per the cache line size and throws
these warnings.

5b84dd67cf usb: replace wait_ms() with mdelay()
Common code has a mdelay() func, so use that instead of the usb-specific
wait_ms() func.  This also fixes the build errors:

5dd95cf93d usb_storage: Fix EHCI "out of buffer pointers" with CD-ROM
When performing large bulk reads from a CD or DVD using the U-Boot
usb_storage driver, it generates requests of up to 20 blocks at a time.

With a standard 512-byte block size, that is 10240 bytes and within the
limit of U-Boot's EHCI driver (maximum 5 pages at 4k per page).

Unfortunately CD-ROM media has a 2048-byte blocksize, resulting in a
maximum transfer size of 40960 bytes, which does not fit.

Since the EHCI specification is impossibly obtuse and far beyond my
comprehension, I chose to dynamically compute the limit based on the
blocksize.
