2009-02-18API: Improve glue mid-layer of the API demo application.Rafal Jaworowski
- Extend ub_dev_read() and ub_dev_recv() so they return the length actually read, which allows for better control and error handling (this introduces additional error code API_ESYSC returned by the glue mid-layer). - Clean up definitions naming and usage. - Other minor cosmetics. Note these changes do not touch the API proper, so the interface between U-Boot and standalone applications remains unchanged. Signed-off-by: Rafal Jaworowski <raj@semihalf.com>

2009-02-18API: Use stack pointer as API signature search hint in the glue layer.Rafal Jaworowski
De-hardcode range in RAM we search for the API signature. Instead use the stack pointer as a hint to narrow down the range in which the signature could reside (it is malloc'ed on the U-Boot heap, and is hoped to remain in some proximity from stack area). Adjust PowerPC code in API demo to the new scheme. Signed-off-by: Rafal Czubak <rcz@semihalf.com> Signed-off-by: Rafal Jaworowski <raj@semihalf.com>

2008-01-29API: Convert conditional building to the new scheme.Rafal Jaworowski
This fixes a build breakage with CONFIG_API enabled, which appeared after the recent changes in the U-Boot build system. Signed-off-by: Rafal Jaworowski <raj@semihalf.com>

2008-01-09API for external applications.Rafal Jaworowski
This is an API for external (standalone) applications running on top of U-Boot, and is meant to be more extensible and robust than the existing jumptable mechanism. It is similar to UNIX syscall approach. See api/README for more details. Included is the demo application using this new framework (api_examples). Please note this is still an experimental feature, and is turned off by default. Signed-off-by: Rafal Jaworowski <raj@semihalf.com>
