disk: part_efi: re-order partition list printf, change case
The partition name is a long variable-length string. Move it last on
the line to ensure consistent layout and that the entries align with
the "header" line. Also, surround it in quotes, so if it's empty, it's
obvious that something is still being printed.
Also, change the case of the LBA numbers; lower-case looks nicer in my
opinion, and will be more consistent with the UUID printing that is
added later in this series.

disk: part_dos: don't claim whole-disk FAT filesystems
Logically, a disk that contains a raw FAT filesystem does not in fact
have a partition table. However, test_part_dos() was claiming that such
disks did in fact have a DOS-style partition table. This caused
get_device_and_partition() not to return a whole-disk disk_partition_t,
since part_type != PART_TYPE_UNKNOWN.
part_dos.c's print_partition_extended() detected the raw FAT filesystem
condition and printed a fake partition table that encompassed the whole
disk.
However, part_dos.c's get_partition_info_extended() did not return any
valid partitions in this case. This combination caused
get_device_and_partition() not to find any valid partitions, and hence
to return an error.
Fix test_part_dos() not to claim that raw FAT filesystems are DOS
partition tables. In turn, this causes get_device_and_partition() to
return a whole-disk disk_partition_t, and hence the following commands
work:
fatls mmc 0 /
fatls mmc 0:auto /
An alternative would be to modify print_partition_extended() to detect
raw FAT filesystems, just like print_partition_extended() does, and to
return a fake partition in this case. However, this seems logically
incorrect, and also duplicates code, since get_device_and_partition()
falls back to returning a whole-disk partition when there is no partition
table on the device.

FAT: check for partition 0 not 1 for whole-disk fs
The recent switch to use get_device_and_partition() from do_fat_ls()
broke the ability to access a FAT filesystem directly on a whole device;
FAT only works within a partition on a device.
This change makes e.g. "fatls mmc 0:0" work; explicitly requesting
partition ID 0 is something that get_device_and_partition() fully
supports. However, fat_register_device() expects partition ID 1 to be
used in the full-disk case; partition ID 1 was previously implicitly
specified when the user didn't actually specify a partition ID. Update
fat_register_device() to expect the correct ID.
This change does imply that if a user explicitly executes "fatls mmc 0:1"
then this will fail, and may be a change in behaviour.
Note that this still prevents "fatls mmc 0:auto" from working. The next
patch will fix that.

and whether the calling command allows the whole device to be returned
or not.

There is two types of Xyref5422 board. One is 3GB ram with 12 ram banks and
another is 2GB ram with 8 ram banks. To initialize memory, we should
define CONFIG_NR_DRAM_BANKS and SDRAM_BANK_SIZE. Unfortunately, previous

to perform safe cache operations. For now we don't do bounce
buffering so getting unaligned buffer is an upper layer error.
We can't check if the buffer is properly padded with current
interface so just assume it is (consider changing with in the
future). The following changes are done:
1. Remove useless length alignment check. We get actual transfer
length not the size of the underlying buffer so it's perfectly
valid for it to be unaligned.
2. Move flush_dcache_range() out of while loop or it will
flush too much.
3. Don't try to fix buffer address before calling invalidate:
if it's unaligned it's an error anyway so let cache subsystem
cry about that.
4. Fix end buffer address to be cacheline aligned assuming upper
layer reserved enough space. This is potentially dangerous
operation so upper layers should be careful about that.

ehci-hcd.c, musb_core, usb.h: Add USB_DMA_MINALIGN define for cache alignment
The USB spec says that 32 bytes is the minimum required alignment.
However on some platforms we have a larger minimum requirement for cache
coherency. In those cases, use that value rather than the USB spec
minimum. We add a cpp check to <usb.h> to define USB_DMA_MINALIGN and
make use of it in ehci-hcd.c and musb_core.h. We cannot use MAX() here
as we are not allowed to have tests inside of align(...).

[marek.vasut]: introduce some crazy macro voodoo

[ilya.yanok]: moved external buffer fixes to separate patch,
we use {ALLOC,DEFINE}_ALIGN_BUFFER macros with alignment of USB_DMA_MINALIGN
for qh_list, qh and qtd structures to make sure they are proper aligned
for both controller and cache operations.

ehci-hcd: program asynclistaddr before every transfer
Move or_asynclistaddr programming to ehci_submit_async()
function to make sure queue head is properly programmed
before every transfer. This solves the problem with changing
qh address.
Also remove unneeded qh_list->qh_link reprogramming at the
end of transfer.
