cpm_uart_map_pram() and cpm_uart_unmap_pram() are very similar for CPM1 and CPM2. On CPM1 cpm_uart_map_pram() uses of_iomap() while CPM2 uses of_address_to_resource()/ioremap(). CPM2 version will also work on CPM1. On CPM2 cpm_uart_map_pram() and cpm_uart_unmap_pram() has a special handling for SMC. Just gate it by an IS_ENABLED(CONFIG_CPM2). So move the CPM2 version into cpm_uart_core.c which is the only user of those two fonctions and refactor to also handle CPM1 as mentionned above. PROFF_SMC_SIZE is only defined for SMC2 and used only there. To make it simple, just use the numerical value 64, this is the only place it is used and anyway there's already the same numerical value for the alignment. Use cpm_muram_alloc() instead of cpm_dpalloc() macro. Then cpm_uart_cpm1.c and cpm_uart_cpm2.c are now empty and go away. Replace printk(KERN_WARN by pr_warn( to make checkpatch happier.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
