Module Parameters for Debugging

3. Differentiating hardware versions
=================================
3. Hardware version 1
To detect the hardware version, read the version number as param[0].param[1].param[2]
4 bytes version: (after the arrow is the name given in the Dell-provided driver)
02.00.22 => EF013
02.06.00 => EF019
In the wild, there appear to be more versions, such as 00.01.64, 01.00.21,
02.00.00, 02.00.04, 02.00.06.
6 bytes:
02.00.30 => EF113
02.08.00 => EF023
02.08.XX => EF123
02.0B.00 => EF215
04.01.XX => Scroll_EF051
04.02.XX => EF051
In the wild, there appear to be more versions, such as 04.03.01, 04.04.11. There
appears to be almost no difference, except for EF113, which does not report
pressure/width and has different data consistency checks.
Probably all the versions with param[0] <= 01 can be considered as
4 bytes/firmware 1. The versions < 02.08.00, with the exception of 02.00.30, as
4 bytes/firmware 2. Everything >= 02.08.00 can be considered as 6 bytes.

5.2.1 Parity checking and packet re-synchronization
There is no parity checking, however some consistency checks can be performed.

For instance for EF113:
SA1= packet[0];
A1 = packet[1];
B1 = packet[2];
SB1= packet[3];
C1 = packet[4];
D1 = packet[5];
if( (((SA1 & 0x3C) != 0x3C) && ((SA1 & 0xC0) != 0x80)) || // check Byte 1
(((SA1 & 0x0C) != 0x0C) && ((SA1 & 0xC0) == 0x80)) || // check Byte 1 (one finger pressed)

(((SA1 & 0xC0) != 0x80) && (( C1 & 0xF0) != 0x00)) ) // check Byte 5
// error detected
For all the other ones, there are just a few constant bits:
if( ((packet[0] & 0x0C) != 0x04) ||
((packet[3] & 0x0f) != 0x02) )
// error detected
In case an error is detected, all the packets are shifted by one (and packet[0] is discarded).

If enabled over the make command line with "W=1", it turns on additional
gcc -W... options for more extensive build-time checking.
KBUILD_BUILD_TIMESTAMP
--------------------------------------------------
Setting this to a date string overrides the timestamp used in the
UTS_VERSION definition (uname -v in the running kernel). The value has to
be a string that can be passed to date -d. The default value
is the output of the date command at one point during build.
KBUILD_BUILD_USER, KBUILD_BUILD_HOST
--------------------------------------------------
These two variables allow to override the user@host string displayed during
boot and in /proc/version. The default value is the output of the commands
whoami and host, respectively.

Example:

During the prepare phase of the build a wrapper include
file is generated in the directory:
arch/$(ARCH)/include/generated/asm
When a header is exported where the architecture uses
the generic header a similar wrapper is generated as part
of the set of exported headers in the directory:
usr/include/asm
The generated wrapper will in both cases look like the following:
