remoteproc/omap: set bootaddr support
Some remote processors (like OMAP4's DSP) require we explicitly set a boot address from which they'd start executing code when taken out of reset. Support for this is now being added to the omap-specific remoteproc driver through a set_bootaddr function in the platform data which, if needed, must be set according to the backend remote processor. For OMAP4's dsp we can use the following control function: .set_bootaddr = omap_ctrl_write_dsp_boot_addr Signed-off-by: Juan Gutierrez <jgutierrez@ti.com> Signed-off-by: Suman Anna <s-anna@ti.com> [ohad: slight changes to the commit log] Signed-off-by: Ohad Ben-Cohen <ohad@wizery.com>
