+ * remember:
+ *
+ * - other at91 parts (like at91sam9) have multiple controllers
+ * and different pin muxing; this version is at91rm9200 specfic.
+ *
+ * - at91sam9261 SPI0 pins are directly muxed with MMC/SD pins.
+ *
+ * - rm9200 spi chipselects drop wrongly, so the native driver
+ * will need to use gpios much like this does.
+ *
+ * - real hardware only allows 8..16 bits per word, while this
+ * bitbanger allows 1..32 (incompatible superset).
+ *
+ * - this disregards clock parameters. with inlined gpio calls,
+ * gcc 3.4.4 produces about 1.5 mbit/sec, more than 2x faster
+ * than using the subroutined veresion from txrx_word().
+ *
+ * - suspend/resume and <linux/clk.h> support is missing ...
