ARMv7-R and TMS570: Re-orider some initialization logic. __start used to called arm_boot() which would return. Then __start would call os_start(). That won't work for the TMS570 if is does a destructive memory tested because the return information will be lost in the stack. Also comment a nuisance assertion. The assertion is probably correct but certainly a nuisance during initial testing

AVR: Fix interrupt bombing during a context switch

TCB_RESTORE macro has a problem when restoring Status Register and returning from the function (in up_fullcontextrestore()) as non-atomic action. If there is some frequently occurring interrupt, chances are that we will enter the interrupt handler just before ret is called. The handler may cause a context switch which, when unrolled, will execute up_fullcontextrestore() function that employs TCB_RESTORE. It will be interrupted again just before return, leaving part of context switch content un-popped again, etc... Thus, chances are that the stack will eventually blow. Note that this is not some edge condition fix. This bug was discovered when testing AVR with UART configured to work on 115200 baud rate.
