config MXC_SAHARA
tristate "Security Hardware Support (FSL SHW)"
---help---
Provides driver and kernel mode API for using cryptographic
accelerators.
config MXC_SAHARA_USER_MODE
tristate "User Mode API for FSL SHW"
depends on MXC_SAHARA
---help---
Provides kernel driver for User Mode API.
config MXC_SAHARA_POLL_MODE
bool "Force driver to POLL for hardware completion."
depends on MXC_SAHARA
default n
---help---
When this flag is yes, the driver will not use interrupts to
determine when the hardware has completed a task, but instead
will hold onto the CPU and continually poll the hardware until
it completes.
config MXC_SAHARA_POLL_MODE_TIMEOUT
hex "Poll loop timeout"
depends on MXC_SAHARA_POLL_MODE
default "0xFFFFFFFF"
help
To avoid infinite polling, a timeout is provided. Should the
timeout be reached, a fault is reported, indicating there must
be something wrong with SAHARA, and SAHARA is reset. The loop
will exit after the given number of iterations.
