The primecell controller on some SoCs, i.e. SoCFPGA, is held in reset by
default. Until recently, the DMA controller was brought out of reset by the
bootloader(i.e. U-Boot). But a recent change in U-Boot, the peripherals
that are not used are held in reset and are left to Linux to bring them

When remoteproc stops a firmware, it sets the MCU PDDS flag, allowing
the platform to reach the Standby power mode if needed.
Symmetrically, clear this flag before running a firmware.
This fixes the issue where the system goes to Standby mode when the
MCU crashes while MPU is in CSTOP mode.

Hello,
I've been hacking around the cdrom driver so that I could get Linux to
mount and access the virtual CD device used by the Beurer GL50 evo
glucometer. The device is fairly quirky and goes into a reset cycle on a
vanilla kernel.
Since I had no idea how to get to the right changes at first,
The cdrom driver predates debugfs and most of the modern debugging
facilities, so instead it has been includings a module parameter and an
ioctl to enable debug messages.
In 2019, debugfs and dynamic debug makes most of that redundant, and even
confusing when trying to trace things in the dept of
The Beurer GL50 evo uses a Cygnal/Cypress-manufactured CD-on-a-chip that
only accepts a subset of SCSI commands.
Most of the not-implemented commands are fine to fail, but a few,
particularly around the MMC or Audio commands, will put the device into an
unrecoverable state, so they need to be
