There is a vendor specific command to read the NVP of the device,
including the KAS. The trick is that the data is randomly
scrambled using a so-called para_noise array of random values.
There seems to be a problem when retrieving large entries (>1000
bytes typically) which causes sg_pt do behave strangely.

This tool can send vendor specific scsi commands to sony nwz
players such as getting serial number, model id, device info,
and others. It can potentially be used to get some private keys
stored on the device but probably not the KAS used to encrypt
firmware upgrades images(UPG).

This tool is specific to the em1/mp200 sony based players. In
deals with raw emmc images (which is possible but hard to get).
This tool is also useful as a documentation of the underlying
emmc format used for a future port.

If interrupts trigger during cache invalidation this could cause memory
corruption. This should be right fix for commit_discard_idcache in

It seems something wrong with cache handling in rk27xx. OF always disable cache
before invalidating cache ways, therefore, now we do the same.
Hopefully this will fix cache handling, but I couldn't contend that it's really so.

The running count is only 16-bit wide, since the always tick
setting derives from the crystal clock at 24MHz the user timer
cannot be set lower than ~300Hz which is already too high.
Switch to the 32KHz crystal source to fix this.

The raw encode mode allows to use the raw encode_page routine on
any file which proved to be useful. The guessed fields of the
headers are based on some rk2918 headers which leaked. They are
mainly informative though (date, version, chip).

when you switch theme away from cabbiev2 to a theme

the icons are still off which doesnt mimic the default

Similar as done with SAPI / MSSP make the current implementation for executable
based TTS engines a base class and create derived classes for each supported
TTS. Removes the need for the implementation to know about the individual TTS
engines.
Add support for speaking directly (i.e. without going through a temporary wave
file, currently only used by espeak).
