next in thread | raw e-mail | index | archive | help
During the next day or so I'll be submitting the following patches for
the arm/at91 (head) tree with the goal of eventually being able to
create a single "GENERIC" kernel that will boot on the at91rm9200,
at91sam926? and at91sam9g20 (as long as boot sequence configures the
multiplexed pins).
I also have patches against 8-current if any one needs them.
These patches have been tested on a KB9202C and an Atmel AT91SAM9G20EK
Rev B. I would appreciate testing (or loan of boards) for the
at91sam926? family.
I am assuming it would be best to submit separate PRs for each of the
changes. If something else is preferred let me know.
at91_mci.c:
* Compile and run time selection of "Slot B" of mci controller.
* Compile and run time selection of 4 wire connection (4x bandwidth
to slot).
* No byte swapping on non-RM9200 targets.
* Fix obscure segfault when bus_dma_load() fails in
at91_mci_start_cmd().
at91_pit.c:
* Support for full resolution timer counter.
* Remove compile time address dependencies.
at91_rst.c: (NEW)
* Support SAM9 reset controller.
* Implement shutdown() on NRST (reset button) and full reset if held
for more the 5 seconds.
at91_wdt.c: (NEW)
* Support SAM9 watchdog timer using the watchdog(9) style interface.
if_ate.c:
* Support for sam9 "EMAC" controller.
* Support for rmii interface to phy.
at91.c & at91sam9.c:
* Eliminate separate at91sam9.c file.
* Add new devices to at91sam9_devs table.
at91_machdep.c & at at91sam9_machdep.c:
* Automatic chip type determination.
* Remove compile time chip dependencies.
* Eliminate separate at91sam9_machdep.c file.
at91_pmc.c:
* Corrected support for all of the sam926? and sam9g20 chips.
* Remove compile time chip dependencies.
