In TPL we try to minimise code size so do not include the PCI subsystem.
We can use fixed BARs and drivers can directly program the devices that
they need.
However we do need to bind the devices on the PCI bus and without PCI this
does not ordinarily happen. As a work-around, define a fake PCI bus which
does this binding, but no other PCI operations. This is a convenient way
to ensure that we can use the same device tree for TPL, SPL and U-Boot
proper:
TPL - CONFIG_TPL_PCI is not set (no auto-config, fake PCI bus)
SPL - CONFIG_SPL_PCI is set (no auto-config but with real PCI bus)
U-Boot - CONFIG_PCI is set (full auto-config after relocation)

At present the value of the timer base is used to determine whether the

never exactly 0 when it is read. However 'time 0' may indicate the time
that the machine was reset so it is useful to be able to denote that.

The signature 0x55 0xAA in bytes 510 and 511 of the first sector can either
indicate a DOS partition table of the first sector of a FAT file system.
The current code tries to check if the partition table is valid by looking
at the boot indicator of the partition entries. But first of all it does
not count from 0 to 3 but only from 0 to 2. And second it misses to
increment the pointer for the partition entry.
If it is a FAT file system can be discovered by looking for the text 'FAT'
at offset 0x36 or 'FAT32' at offset 0x52. In a DOS PBR there are no
partition entries, so those bytes are undefined. Don't require the byte at
offset 0x1BE to differ from 0x00 and 0x80.
With the patch the logic is changed as follows:
If the partition table has either an invalid boot flag for any partition or
has no partition at all, check if the first sector is a DOS PBR by looking
at the FAT* signature.

It's possible that the data cache for the buffer still holds data
to be flushed to memory, since the buffer was probably used as stack
before. Thus we need to make sure to flush it also on reads, since
it's possible that the cache is automatically flused to memory after
the NVMe DMA transfer happened, thus overwriting the NVMe transfer's
data. Also add a missing dcache flush for the prp list.

Profiling the EHCI driver shows a significant performance problem in
ehci_submit_async(). Specifically, this function keeps enabling and
disabling async schedule back and forth for every single transaction.
However, enabling/disabling the async schedule does not take effect
immediatelly, but instead may take up to 1 mS (8 uFrames) to complete.
This impacts USB storage significantly, esp. since the recent reduction
of maximum transfer size to support more USB storage devices. This in
turn results in sharp increase in the number of ehci_submit_async()
calls. Since one USB storage BBB transfer does three such calls and
the maximum transfer size is 120 kiB, the overhead is 6 mS per 120 kiB,
which is unacceptable.
However, this overhead can be removed simply by keeping the async
schedule running. Specifically, the first transfer starts the async
schedule and then each and every subsequent transfer only adds a new
QH into that schedule, waits until the QH is completed and does NOT
disable the async schedule. The async schedule is stopped only by
shutting down the controller, which must happen before moving out
of U-Boot, otherwise the controller will corrupt memory.

Clear the USB_READY flag in the storage driver only in case there
is an error, otherwise usb_stor_BBB_transport() waits 5 mS before
doing anything every single time.
This is because the USB_READY flag is only ever set in
usb_test_unit_ready(), which is called only upon storage device
probe, not between each and every request. However, the device
cannot move out of USB_READY state once it was initialized.
