Laurent Pinchart d464df2667 [POWERPC] cpm_uart: Allocate DPRAM memory for SMC ports on CPM2-based platforms. ... This patch allocates parameter RAM for SMC serial ports without relying on previous initialisation by a boot loader or a wrapper layer. SMC parameter RAM on CPM2-based platforms can be allocated anywhere in the general-purpose areas of the dual-port RAM. The current code relies on the boot loader to allocate a section of general-purpose CPM RAM and gets the section address from the device tree. This patch modifies the device tree address usage to reference the SMC parameter RAM base pointer instead of a pre-allocated RAM section and allocates memory from the CPM dual-port RAM when initialising the SMC port. CPM1-based platforms are not affected.
