Bandan Das 53735bef10 usb-mtp: Advertise SendObjectInfo for write support
This patch implements a dummy ObjectInfo structure so that
it's easy to typecast the incoming data. If the metadata is
valid, write_pending is set. Also, the incoming filename
is utf-16, so, instead of depending on external libraries, just
implement a simple function to get the filename

Bandan Das 88d5f381ec usb-mtp: Introduce write support for MTP objects
Allow write operations on behalf of the initiator. The
precursor to write is the sending of the write metadata
that consists of the ObjectInfo dataset. This patch introduces
a flag that is set when the responder is ready to receive
write data based on a previous SendObjectInfo operation by
the initiator (The SendObjectInfo implementation is in a
later patch)

Bandan Das ec6206a68f usb-mtp: Support delete of mtp objects
Write of existing objects by the initiator is acheived by
making a temporary buffer with the new changes, deleting the
old file and then writing a new file with the same name.

Also, add a "readonly" property which needs to be set to false
for deletion to work.

Collin L. Walling 53b310ce53 s390-ccw: use zipl values when no boot menu options are present
If no boot menu options are present, then flag the boot menu to
use the zipl options that were set in the zipl configuration file
(and stored on disk by zipl). These options are found at some
offset prior to the start of the zipl boot menu banner. The zipl
timeout value is limited to a 16-bit unsigned integer and stored
as seconds, so we take care to convert it to milliseconds in order
to conform to the rest of the boot menu functionality. This is
limited to CCW devices.

For reference, the zipl configuration file uses the following
fields in the menu section:

      prompt=1      enable the boot menu
      timeout=X     set the timeout to X seconds

To explicitly disregard any boot menu options, then menu=off or
<bootmenu enable='no' ... /> must be specified.

Collin L. Walling dbf2091aba s390-ccw: set cp_receive mask only when needed and consume pending service irqs
It is possible while waiting for multiple types of external
interrupts that we might have pending irqs remaining between
irq consumption and irq-type disabling. Those interrupts
could potentially propagate to the guest after IPL completes
and cause unwanted behavior.

As it is today, the SCLP will only recognize write events that
are enabled by the control program's send and receive masks. To
limit the window for, and prevent further irqs from, ASCII
console events (specifically keystrokes), we should only enable
the control program's receive mask when we need it.

While we're at it, remove assignment of the (non control program)
send and receive masks, as those are actually set by the SCLP.

Collin L. Walling ff5dbf1bc3 s390-ccw: read user input for boot index via the SCLP console
Implements an sclp_read function to capture input from the
console and a wrapper function that handles parsing certain
characters and adding input to a buffer. The input is checked
for any erroneous values and is handled appropriately.

A prompt will persist until input is entered or the timeout
expires (if one was set). Example:

      Please choose (default will boot in 10 seconds):

Correct input will boot the respective boot index. If the
user's input is empty, 0, or if the timeout expires, then
the default zipl entry will be chosen. If the input is
within the range of available boot entries, then the
selection will be booted. Any erroneous input will cancel
the timeout and re-prompt the user.

Collin L. Walling 118ee80f79 s390-ccw: move auxiliary IPL data to separate location
The s390-ccw firmware needs some information in support of the
boot process which is not available on the native machine.
Examples are the netboot firmware load address and now the
boot menu parameters.

While storing that data in unused fields of the IPL parameter block
works, that approach could create problems if the parameter block
definition should change in the future. Because then a guest could
overwrite these fields using the set IPLB diagnose.

In fact the data in question is of more global nature and not really
tied to an IPL device, so separating it is rather logical.

This commit introduces a new structure to hold firmware relevant
IPL parameters set by QEMU. The data is stored at location 204 (dec)
and can contain up to 7 32-bit words. This area is available to
programming in the z/Architecture Principles of Operation and
can thus safely be used by the firmware until the IPL has completed.
