Namespaces
namespace	sd
	The SD card's SPI-mode block driver (CHSd).

Typedefs
typedef void(*	sd::BlockFn) (const uint8_t *block, void *ctx)
	What stream() calls with each block, in order.

Functions
bool	sd::init ()
	Wakes the card and identifies it (SD v1, SDSC v2, SDHC/SDXC).
bool	sd::read (uint32_t lba, uint8_t *dst)
	Reads one 512-byte block (CMD17), polled at 12 MHz.
bool	sd::stream (uint32_t lba, uint32_t n, uint8_t *buf0, uint8_t *buf1, BlockFn fn, void *ctx)
	Reads n consecutive blocks with one multi-block read (CMD18), handing each to fn while the next one arrives.
