* CGW_FILTER (length 8 bytes):
* Sets a CAN receive filter for the gateway job specified by the

* <u8> affected CAN frame elements
*
* CGW_CS_XOR (length 4 bytes):
* Set a simple XOR checksum starting with an initial value into
* data[result-idx] using data[start-idx] .. data[end-idx]
*
* The XOR checksum is calculated like this:
*
* xor = init_xor_val
*

* xor ^= can_frame.data[i]
*
* can_frame.data[ result_idx ] = xor
*

* Set a CRC8 value into data[result-idx] using a given 256 byte CRC8 table,
* a given initial value and a defined input data[start-idx] .. data[end-idx].
* Finally the result value is XOR'ed with the final_xor_val.
*
* The CRC8 checksum is calculated like this:
*
* crc = init_crc_val
*
* for (i = from_idx .. to_idx)
* crc = crctab[ crc ^ can_frame.data[i] ]
*
* can_frame.data[ result_idx ] = crc ^ final_xor_val
*
* The calculated CRC may contain additional source data elements that can be
* defined in the handling of 'checksum profiles' e.g. shown in AUTOSAR specs
* like http://www.autosar.org/download/R4.0/AUTOSAR_SWS_E2ELibrary.pdf
* E.g. the profile_data[] may contain additional u8 values (called DATA_IDs)
* that are used depending on counter values inside the CAN frame data[].
* So far only three profiles have been implemented for illustration.
*
* Remark: In general the attribute data is a linear buffer.
* Beware of sending unpacked or aligned structs!

/*
* There are several things to be aware of that aren't at all obvious:
*
*
* SOCKETS, SOCKET SETS, BANKS, ROWS, CHIP-SELECT ROWS, CHANNELS, etc..
*
* These are some of the many terms that are thrown about that don't always
* mean what people think they mean (Inconceivable!). In the interest of
* creating a common ground for discussion, terms and their definitions
* will be established.
*
* Memory devices: The individual chip on a memory stick. These devices
* commonly output 4 and 8 bits each. Grouping several
* of these in parallel provides 64 bits which is common
* for a memory stick.
*
* Memory Stick: A printed circuit board that aggregates multiple
* memory devices in parallel. This is the atomic
* memory component that is purchaseable by Joe consumer
* and loaded into a memory socket.
*
* Socket: A physical connector on the motherboard that accepts
* a single memory stick.
*
* Channel: Set of memory devices on a memory stick that must be
* grouped in parallel with one or more additional
* channels from other memory sticks. This parallel
* grouping of the output from multiple channels are
* necessary for the smallest granularity of memory access.
* Some memory controllers are capable of single channel -
* which means that memory sticks can be loaded
* individually. Other memory controllers are only
* capable of dual channel - which means that memory
* sticks must be loaded as pairs (see "socket set").
*
* Chip-select row: All of the memory devices that are selected together.
* for a single, minimum grain of memory access.
* This selects all of the parallel memory devices across
* all of the parallel channels. Common chip-select rows
* for single channel are 64 bits, for dual channel 128
* bits.
*
* Single-Ranked stick: A Single-ranked stick has 1 chip-select row of memory.
* Motherboards commonly drive two chip-select pins to
* a memory stick. A single-ranked stick, will occupy
* only one of those rows. The other will be unused.
*
* Double-Ranked stick: A double-ranked stick has two chip-select rows which
* access different sets of memory devices. The two
* rows cannot be accessed concurrently.
*
* Double-sided stick: DEPRECATED TERM, see Double-Ranked stick.
* A double-sided stick has two chip-select rows which
* access different sets of memory devices. The two
* rows cannot be accessed concurrently. "Double-sided"
* is irrespective of the memory devices being mounted
* on both sides of the memory stick.
*
* Socket set: All of the memory sticks that are required for
* a single memory access or all of the memory sticks
* spanned by a chip-select row. A single socket set
* has two chip-select rows and if double-sided sticks
* are used these will occupy those chip-select rows.
*
* Bank: This term is avoided because it is unclear when
* needing to distinguish between chip-select rows and
* socket sets.
*
* Controller pages:
*
* Physical pages:
*
* Virtual pages:

* a starting id!).
*
* This platform data structure should be used to provide the base id
