+How to use SD/MMC cards with Atmel SoCs having MCI hardware
+-----------------------------------------------------------
+2010-08-16 Reinhard Meyer <reinhard.meyer@emk-elektronik.de>
+
+This is a new approach to use Atmel MCI hardware with the
+general MMC framework. Therefore it benefits from that
+framework's abilities to handle SDHC Cards and the ability
+to write blocks.
+
+- AT91SAM9XE512 (tested, will definitely work with XE128 and XE256)
+- AT91SAM9260 (not tested, but MCI is to AT91SAM9XE)
+- AT91SAM9G20 (not tested, should work)
+
+It should work with all other ATMEL devices that have MCI,
+including AVR32.
+
+The generic driver does NOT assign port pins to the MCI block
+nor does it start the MCI clock. This has to be handled in a
+board/SoC specific manner before the driver is initialized:
+
+example: this is added to at91sam9260_devices.c:
+
+#if defined(CONFIG_ATMEL_MCI) || defined(CONFIG_GENERIC_ATMEL_MCI)
+void at91_mci_hw_init(void)
+{
+	at91_set_a_periph(AT91_PIO_PORTA, 8, PUP);	/* MCCK */
+#if defined(CONFIG_ATMEL_MCI_PORTB)
+	at91_set_b_periph(AT91_PIO_PORTA, 1, PUP);	/* MCCDB */
+	at91_set_b_periph(AT91_PIO_PORTA, 0, PUP);	/* MCDB0 */
+	at91_set_b_periph(AT91_PIO_PORTA, 5, PUP);	/* MCDB1 */
+	at91_set_b_periph(AT91_PIO_PORTA, 4, PUP);	/* MCDB2 */
+	at91_set_b_periph(AT91_PIO_PORTA, 3, PUP);	/* MCDB3 */
+#else
+	at91_set_a_periph(AT91_PIO_PORTA, 7, PUP);	/* MCCDA */
+	at91_set_a_periph(AT91_PIO_PORTA, 6, PUP);	/* MCDA0 */
+	at91_set_a_periph(AT91_PIO_PORTA, 9, PUP);	/* MCDA1 */
+	at91_set_a_periph(AT91_PIO_PORTA, 10, PUP);	/* MCDA2 */
+	at91_set_a_periph(AT91_PIO_PORTA, 11, PUP);	/* MCDA3 */
+#endif
+}
+#endif
+
+the board specific file need added:
+...
+#ifdef CONFIG_GENERIC_ATMEL_MCI
+# include <mmc.h>
+#endif
+...
+#ifdef CONFIG_GENERIC_ATMEL_MCI
+/* this is a weak define that we are overriding */
+int board_mmc_init(bd_t *bd)
+{
+	/* Enable clock */
+	at91_sys_write(AT91_PMC_PCER, 1 << AT91SAM9260_ID_MCI);
+	at91_mci_hw_init();
+
+	/* This calls the atmel_mci_init in gen_atmel_mci.c */
+	return atmel_mci_init((void *)AT91_BASE_MCI);
+}
+
+/* this is a weak define that we are overriding */
+int board_mmc_getcd(u8 *cd, struct mmc *mmc)
+{
+	/*
+	 * the only currently existing use of this function
+	 * (fsl_esdhc.c) suggests this function must return
+	 * *cs = TRUE if a card is NOT detected -> in most
+	 * cases the value of the pin when the detect switch
+	 * closes to GND
+	 */
+	*cd = at91_get_gpio_value (CONFIG_SYS_MMC_CD_PIN) ? 1 : 0;
+	return 0;
+}
+
+#endif
+
+and the board definition files needs:
+
+/* SD/MMC card */
+#define CONFIG_MMC			1
+#define CONFIG_GENERIC_MMC		1
+#define CONFIG_GENERIC_ATMEL_MCI	1
+#define CONFIG_ATMEL_MCI_PORTB		1	/* Atmel XE-EK uses port B */

+ * this driver supports the enhanced embedded flash in the Atmel
+ * AT91SAM9XE devices with the following geometry:
+ *
+ * AT91SAM9XE128: 1 plane of  8 regions of 32 pages (total  256 pages)
+ * AT91SAM9XE256: 1 plane of 16 regions of 32 pages (total  512 pages)
+ * AT91SAM9XE512: 1 plane of 32 regions of 32 pages (total 1024 pages)
+ * (the exact geometry is read from the flash at runtime, so any
+ *  future devices should already be covered)
+ *
+ * Regions can be write/erase protected.
+ * Whole (!) pages can be individually written with erase on the fly.
+ * Writing partial pages will corrupt the rest of the page.
+ *
+ * The flash is presented to u-boot with each region being a sector,
+ * having the following effects:
+ * Each sector can be hardware protected (protect on/off).
+ * Each page in a sector can be rewritten anytime.
+ * Since pages are erased when written, the "erase" does nothing.
+ * The first "CONFIG_EFLASH_PROTSECTORS" cannot be unprotected
+ * by u-Boot commands.
+ *
+ * Note: Redundant environment will not work in this flash since
+ * it does use partial page writes. Make sure the environent spans
+ * whole pages!
+ */
+
+/*
+ * optional TODOs (nice to have features):
+ *
+ * make the driver coexist with other NOR flash drivers
+ *	(use an index into flash_info[], requires work
+ *	in those other drivers, too)
+ * Make the erase command fill the sectors with 0xff
+ *	(if the flashes grow larger in the future and
+ *	someone puts a jffs2 into them)
+ * do a read-modify-write for partially programmed pages
