| Status on SPI subsystem: | |
| ======================= | |
| SPI COMMAND (common/cmd_sf, cmd_spi): | |
| - | |
| SPI FLASH (drivers/mtd/spi): | |
| - sf_probe.c: SPI flash probing code. | |
| - sf_ops.c: SPI flash operations code. | |
| - sf.c: SPI flash interface, which interacts controller driver. | |
| - Bank Address Register (Accessing flashes > 16Mbytes in 3-byte addressing) | |
| - Added memory_mapped support for read operations. | |
| - Common probe support for all supported flash vendors except, ramtron. | |
| - Extended read commands support(dual read, dual IO read) | |
| - Quad Page Program support. | |
| - Quad Read support(quad fast read, quad IO read) | |
| - Dual flash connection topology support(accessing two spi flash memories with single cs) | |
| - Banking support on dual flash connection topology. | |
| SPI DRIVERS (drivers/spi): | |
| - | |
| TODO: | |
| - Runtime detection of spi_flash params, SFDP(if possible) | |
| - Add support for multibus build/accessing. | |
| - Need proper cleanups on spi_flash and drivers. | |
