* fix copyrights (this should happen before the mm-z1-x5 merge is brought back into the

SVN t2 mainline).

* apps/IPBaseStation: defines a reset in a particularily ugly way. Needs to be

fixed and made part of the platform/cpu definition.

apps/IPBaseStation deleted.

-- What is the purpose of msp430regtypes.h? Is there a easier way to deal with this?

No. This is how it is done. Provides the linkage to msp430hardware.h and various

defines that are there, ie. MSP430_NORACE(xxxxx). etc.

* There are multiple copies of msp430hardware.h. Is that reasonable?

* i2c for msp430 isn't done yet. needs to be cleaned up and made less ugly. Interface

needs to be finished.

shimmer/span has a working i2c. Investigate bringing that i2c implementation into the

main t2 usart and usci areas.

* CC2420 modules use LocalIeeeEui64C to obtain an ipv6 link-local address. Z1 needs to

provide. If the ds2401 (serializer chip) isn't supported how is this done?

* Currently config structs get put into ram via the data copy into ram mechanism. This

means that it takes up room in RAM and ROM. Suboptimal.

Some platforms (Epic?) actual modify parts of the config structure on the fly. These

need to stay in ram. Look at const stash on z1-rework.

* Original mm_core port removed McuPowerOverride. Why?

* usart/msp430usart.h usci/msp430usci.h: define baud rates and configurations and h/w config

values are defined. Originally for the msp430f1611. How should this stuff get dealt with

for other chips and platforms. Clocks and configuration values possible are quite variable

with new chips. This should probably be a platform dependency.

This should be changed to get rid of the bit struct and replaced with something that uses

the stuff from the TI HEADERS.

Are the bit fields really used or can we nuke them. Configuration uses a configuration struct

and functional stuff is code that uses the definitions in the TI HEADERS and other cpu headers.

bit fields are used by the basic definitions in the interface files. To get rid of the bit fields

requires completly redefining the Hpl interfaces.

* Need better approach to assigning ports. Should be a platform thing. this makes it so drivers

don't wire directly but instead wire to the platform ports. Or conversely the platform provides

the wiring... How to do this?

* Do we want to put in TOSThreads support? Best way if yes is to #ifdef needed code in

the interrupt handlers. Old school mechanism clones the code. Why did Kevin do that?

-- (done) Z1 uses I2C but never defines SDA or SCL. Rather it overlays the I2C pins on the SPI pins.

Works but isn't clean or straight forward. Confusing for someone new picking up what is going

on.

(done) Z1 currently overloads the SPI pins. Switch to using I2C pins so it is clean.

-- should UcsiB add call for Usci.setUmctl(0)? No. not defined (it exists though) but is reset to 0.

* clean up msp430_have_* checks. old old toolchain.

* tos/lib/tosboot/msp430 has various h/w dependencies. Add support for other msp430 processors.

One way is to simply extend what is in tos/lib/tosboot. That is keep the h/w dependancies in

tos/lib/tosboot/msp430.

A better way would be to figure out how to make tos/lib/tosboot processor independent and

move processor dependancies into tos/chips/msp430. To start simply make the msp430 code

become processor independent and the pieces in tos/lib/tosboot/msp430 reference the

appropriate processor dependent code in tos/chips (pick via platform file).

* dco_calib: needs to be evaluated for BC2 (RSEL 4 bits vs. 3 bits). RSEL_MASK should take care

of it but needs to be checked.

* dco_calib: currently busy wait runs two full ACLK_CALIB_PERIOD cycles. This can be shortened to one ACLK

edge and then an ACLK_CALIB_PERIOD. This may not be worth it because what we really want is an integrated

recalibration mechanism that runs off interrupts. One pass with ACLK_CALIB_PERIOD is 8 * 1/32768 = 244uS.

But it is a binary search and the entire process takes about 9ms. So we probably want to do this off

interrupts. But what about things like interrupt latency etc.

* dco_calib: termination condition checks for dco 7 because mod bits no longer take effect. Verify for BC2

and BASIC_CLOCK.
