a478a26cd0 x86: timer: Use a separate flag for whether timer is inited
At present the value of the timer base is used to determine whether the
timer has been set up or not. It is true that the timer is essentially
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.

Update the code to use a separate flag instead.

096c71e34b x86: timer: Set up the timer in timer_early_get_count()
This function can be called before the timer is set up. Make sure that the
init function is called so that it works correctly.

This is needed so that bootstage can work correctly in TPL.

c53b318e1b spi: Add support for memory-mapped flash
On x86 platforms the SPI flash can be mapped into memory so that the
contents can be read with normal memory accesses.

Add a new SPI method to find the location of the SPI flash in memory. This
differs from the existing device-tree "memory-map" mechanism in that the
location can be discovered at run-time.

e1500a6ce2 spl: Correct priority selection for image loaders
At present the name of the image comes first in the linker-list symbol
used. This means that the name of the function sets the sort order, which
is not the intention.

Update it to put the boot-device type first, then the priority. This
produces the expected behaviour.

bb43c27847 cmd: avb: Fix requested partitions list
The requested_partitions[] array should contain only boot partitions.
Usually it's only 'boot' partition, as can be seen in [1]. Also, seems
like the requested_partitions[] are only used when there is no 'vbmeta'
partition [2], which is not a regular use-case.

Make requested_partitions[] contain only 'boot' partition as it was
supposed to be, and also make that array to be a local in
do_avb_verify_part() function, as nobody else needs that.

            -d zImage -b zynq-microzed.dtb -i initramfs.cpio image.ub

the type of fdt subimage is the same as of the main kernel image and
the architecture of the initramfs image is not set. Such an image is
refused by U-Boot when booting. This commits sets the mentioned
attributes, allowing to use the "-f auto" mode in this case instead of
writing full .its file.

Add a simple implementation of this function, to allow logging to be

implementation.

To keep the code size small,

- The function is built only when logging is enabled, as it
  (currently) is not needed otherwise; and
- Like the existing implementation of snprintf(), its buffer-size
  parameter is ignored.

34856b0f1c disk: part_dos: correctly detect DOS PBR
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.

2f83481dff nvme: use page-aligned buffer for identify command
Change the stack-allocated buffer for the identification command
to explicitly allocate page-aligned buffers.  Even though the spec
seems to allow having admin queue commands on non page-aligned
buffers, it seems to not be possible on my i.MX8MQ board with a
a Silicon Power P34A80.  Since all of the NVMe drivers I have seen
always do admin commands on a page-aligned buffer, which does work
on my system, it makes sense for us to do that as well.

8c403402ca nvme: flush dcache on both r/w, and the prp list
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.

02b0e1a36c usb: ehci-hcd: Keep async schedule running
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.

da3d1c499f usb: storage: Only clear READY flag on error
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.

7d6fd7f0ba usb: storage: Limit transfer size to 120 kiB
Due to constant influx of more and more weird and broken USB sticks,
do as Linux does in commit 779b457f66e10de3471479373463b27fd308dc85

    usb: storage: scsiglue: further describe our 240 sector limit

    Just so we have some sort of documentation as to why
    we limit our Mass Storage transfers to 240 sectors,
    let's update the comment to make clearer that
    devices were found that would choke with larger
    transfers.

    While at that, also make sure to clarify that other
    operating systems have similar, albeit different,
    limits on mass storage transfers.

And reduce the maximum transfer length of USB storage to 120 kiB.
