* libchip/i2c/spi-sd-card.c: Updated to the libblock changes.

	* libchip/ide/ata.c: Change to use a mutex rather than disable
	pre-emption. Updated to the libblock changes.

	* libchip/ide/ata_internal.h: Updated to the new chains API.

	* libchip/ide/ide_controller.c: Updated to the libblock
	changes. Added come debug tracing.

	* libchip/ide/ide_ctrl_cfg.h, libchip/ide/ide_ctrl_io.h: Updated
	to the libblock changes.
