mx6sabresd_spl.cfg configures CCM registers, GPR registers and CCM_CCOSR.
Move the configuration to the spl code.
CCM_CCOSR setting is no longer required to get audio functionality in the kernel, so remove such setting.
Signed-off-by: Fabio Estevam fabio.estevam@freescale.com --- Hi Stefano,
Actually I would like to get rid of mx6sabresd_spl.cfg completely, but when I tried to remove it, I ended up with SPL not being built.
Any suggestions?
