This series adjusts the block device code to support conversion to driver model. Specifically
- A new 'legacy' block interface is created, allowing block devices to be
defined by a linker list and accessed through function calls
- Block device commands (such as sata and scsi) are adjusted to use these
functions rather than the block device array directly
- These same function calls are then implemented by the block uclass
- The existing block-device table in part.c is dropped
- The opportunity is taken to clean up the code style, as block devices are
one of the few remaining dark corners in U-Boot
It is useful to enable all block device drivers with sandbox. This improves sandbox code coverage and allows tests to be written. The following are enabled by this series:
- IDE
- SCSI
- SATA
- Systemace
USB was already enabled. MMC will be enabled by a future series. Note that these devices do not actually function in sandbox, but the code is compiled.
As mentioned, future work will enable MMC for sandbox including adding rudimentary sandbox SD card emulation. It would also be possible to create emulations for IDE, SCSI, SATA and Systemace but that work is not planned.
It should be noted that the current CONFIG_DM_MMC option does not fully enable driver model for MMC, since the MMC operations are not running through driver model. This will need to be addressed at some point.
This series is available at u-boot-dm/blka-working
I'd like to apply this series in the next few days - please let me know if there are any more comments.
