1: - board/altera/common/flash.c:flash_erase():
o allow interrupts befor get_timer() call
o check-up each erased sector and avoid unexpected timeouts
- board/altera/dk1c20/dk1s10.c:board_early_init_f():
o enclose sevenseg_set() in cpp condition
- remove the ASMI configuration for DK1S10_standard_32 (never present)
- fix some typed in mistakes in the NIOS documentation
2: - split DK1C20 configuration into several header files:
o two new files for each NIOS CPU description
o U-Boot related part is remaining in DK1C20.h
3: - split DK1S10 configuration into several header files:
o two new files for each NIOS CPU description
o U-Boot related part is remaining in DK1S10.h
4: - Add support for the Microtronix Linux Development Kit
NIOS CPU configuration at the Altera Nios Development Kit,
Stratix Edition (DK-1S10)
5: - Add documentation for the Altera Nios Development Kit,
Stratix Edition (DK-1S10)
6: - Add support for the Nios Serial Peripharel Interface (SPI)
(master only)
7: - Add support for the common U-Boot SPI framework at
RTC driver DS1306

/*************************************************************************
|
|
* Exception Vector Table
|
|
*
|
|
* This could have gone in the cpu soure tree, but the whole point of
|
|
* Nios is customization -- and polluting the cpu source tree with
|
|
* board-specific ifdef's really defeats the purpose, no? With this in
|
|
* the board-specific tree, each board has the freedom to organize
|
|
* vectors/traps, etc anyway it wants. The init code copies this table
|
|
* to the proper location.
|
|
*
|
|
* Each board can do what it likes here. But there are four "standard"
|
|
* handlers availble:
|
|
*
|
|
* _cwp_lolimit -Handles register window underflows.
|
|
* _cwp_hilimit -Handles register window overflows.
|
|
* _timebase_int -Increments the timebase.
|
|
* _def_xhandler -Default exception handler.
|
|
*
|
|
* _timebase_int handles a Nios Timer interrupt and increments the
|
|
* timestamp used for the get_timer(), reset_timer(), etc. routines. It
|
|
* expects the timer to be configured like the standard-32 low priority
|
|
* timer.
|
|
*
|
|
* _def_xhandler dispatches exceptions/traps via the external_interrupt()
|
|
* routine. This lets you use the irq_install_handler() and handle your
|
|
* interrupts/traps with code written in C.
