* drivers: Introduce a simplified remoteproc frameworkNishanth Menon2015-10-22-0/+163
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many System on Chip(SoC) solutions are complex with multiple processors on the same die dedicated to either general purpose of specialized functions. Many examples do exist in today's SoCs from various vendors. Typical examples are micro controllers such as an ARM M3/M0 doing a offload of specific function such as event integration or power management or controlling camera etc. Traditionally, the responsibility of loading up such a processor with a firmware and communication has been with a High Level Operating System(HLOS) such as Linux. However, there exists classes of products where Linux would need to expect services from such a processor or the delay of Linux and operating system being able to load up such a firmware is unacceptable. To address these needs, we need some minimal capability to load such a system and ensure it is started prior to an Operating System(Linux or any other) is started up. NOTE: This is NOT meant to be a solve-all solution, instead, it tries to address certain class of SoCs and products that need such a solution. A very simple model is introduced here as part of the initial support that supports microcontrollers with internal memory (no MMU, no execution from external memory, or specific image format needs). This basic framework can then (hopefully) be extensible to other complex SoC processor support as need be.

* config_distro_bootcmd.h: Use a private variable for bootpartSjoerd Simons2015-10-22-7/+11
| | | | | | | | | | | | | | Hush has an oddity where using ${var} causes var to resolved in the the global address space (iotw the environment) first and only afterwards will the local variable space be searched. This causes odd side-effects when iterating over the boot partitions using ${bootpart} if the environment also has a bootpart variable (e.g. for the various TI boards). Fix this by using the hopefully more unique ${distro_bootpart} instead of ${bootpart}. Signed-off-by: Sjoerd Simons <sjoerd.simons@collabora.co.uk> Acked-by: Stephen Warren <swarren@wwwdotorg.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Advantech SOM-6896 is a Broadwell U based COM Express Compact Module Type 6. This patch adds support for it as a coreboot payload. On board SATA and SPI are functional. On board Ethernet isn't functional but since it's optional and ties up a PCIe x4 that is otherwise brought out, this isn't a concern at the moment.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far VxWorks bootline can be contructed from various environment variables, but when these variables do not exist we get these from corresponding config macros. This is not helpful as it requires rebuilding U-Boot, and to make sure these config macros take effect we should not have these environment variables. This is a little bit complex and confusing. Now we change the logic to always contruct the bootline from environments (the only single source), by adding two new variables "bootdev" and "othbootargs", and adding some comments about network related settings mentioning they are optional.
