Kwikstik hal patch

The attached patch provides HAL for the Freescale Kwikstik board. The
implementation is a clone of the twr_k40x256 hal with clock frequency and
diagnostic uart adjusted to match the particulars of the Kwikstick board.

Hi Tomas

Thank you for bringing eCos on Kwikstik.

I noticed some macros related to other your contributions in plf_io.h and that
may require synchronization. This will put Kwikstik on a wait. There may be
another reason for deferring inclusion of Kwinkstik, some work of my own that
will introduce FlexBus memory that may introduce some changes in memory layout
CDLs. I hope to have them in Bugzilla next week.

The I2C macros can be removed, they are not used anywhere else in the patch
(they got in because of the order of my various patches in my local tree), but
I won't be able to come back to this for about week.

Hi Tomas.

I have submitted an update to Kinetis HAL in Bug 1001450. It introduces some
changes to Startup type that, in their final form, will need to propagate to
Kwikstik HAL too. In that sense this bug depends on Bug 1001450.

OK, I shall update the patch to that effect when it lands in the repository.

I am also adding a dependency on bug 1001428, the Freescale SLCD HAL patch.

Tomas

I have checked the bug #1001450 patches in. Can you synchronize this port with
CVS?
Hint: Since this port is based on TWR-K40X256, IMO the easy way is to look at
Attachment 1561 for diffs (with respect to original Kwikstik patch).

P.S.

If you can't test MMC you can omit it.

Hi Tomas

I now have a KwikStik board on my desk. Do you have any time to update your
patch per comment #6 in the short term? If not, I may have a look at doing this
myself as I would like to start experimenting with the board soon.

Tomas, have you been using ROM startup with KwikStik mainly? Or RAM startup
with stubs? Or RAM startup without stubs? Have you been using the J-Link GDB
server? Just interested in what might be a good (well tested) place to start
experimenting.

Hi John

FYI PEEDI has JTAG/SWD support for Kinetis including flashing. (you mentioned
in some conversation so I assume you might have one).

John, I have been using both ROM and RAM startup, though not entirely sure
about the gdb stubs (whatever is the default setting in the config), they both
should work fine. I use OpenOCD as gdb server with J-Link. (I got a driver for
the Kwikstik LCD together with couple of homemade bitmapped fonts, but had to
put that on back burner at the moment; I expect to have some time to come back
to this in couple of weeks, though I need to get the i2c driver for kinetis out
of the way first).

Tomas, your port is working well for me with changes per comment #6. I will
check this in when I'm back at my desk later this week. Let me know if you
could make use of a revised patch in the meantime.

FYI, I'm using the J-Link GDB server with SRAM startup.
