[POWERPC] cpm_uart: Allocate DPRAM memory for SMC ports on CPM2-based platforms.

2008-04-17T06:01:36Z

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. Signed-off-by: Laurent Pinchart Acked-by: Scott Wood Signed-off-by: Kumar Gala

[POWERPC] CPM: Rename commproc to cpm1 and cpm2_common.c to cpm2.c

2008-01-28T14:31:05Z

Rename commproc.[ch] to cpm1.[ch] to be more consistent with cpm2. Also rename cpm2_common.c to cpm2.c as suggested by Scott Wood. Adjust the includes accordingly. Signed-off-by: Jochen Friedrich Signed-off-by: Kumar Gala

[POWERPC] Move CPM command handling into the cpm drivers

2007-12-14T04:47:16Z

This patch moves the CPM command handling into commproc.c for CPM1 and cpm2_common.c. This is yet another preparation to get rid of drivers accessing the CPM via the global cpmp. Signed-off-by: Jochen Friedrich Acked-by: Scott Wood Acked-by: Arnd Bergmann Signed-off-by: Vitaly Bordug

[POWERPC] cpm: Describe multi-user ram in its own device node.

2007-10-04T20:47:05Z

The way the current CPM binding describes available multi-user (a.k.a. dual-ported) RAM doesn't work well when there are multiple free regions, and it doesn't work at all if the region doesn't begin at the start of the muram area (as the hardware needs to be programmed with offsets into this area). The latter situation can happen with SMC UARTs on CPM2, as its parameter RAM is relocatable, u-boot puts it at zero, and the kernel doesn't support moving it. It is now described with a muram node, similar to QE. The current CPM binding is sufficiently recent (i.e. never appeared in an official release) that compatibility with existing device trees is not an issue. The code supporting the new binding is shared between cpm1 and cpm2, rather than remain separated. QE should be able to use this code as well, once minor fixes are made to its device trees.

[POWERPC] cpm_uart: sparse fixes

[POWERPC] cpm_uart: Be an of_platform device when CONFIG_PPC_CPM_NEW_BINDING is set.

2007-10-04T01:36:35Z

The existing OF glue code was crufty and broken. Rather than fix it, it has been removed, and the serial driver now talks to the device tree directly. The non-CONFIG_PPC_CPM_NEW_BINDING code can go away once CPM platforms are dropped from arch/ppc (which will hopefully be soon), and existing arch/powerpc boards that I wasn't able to test on for this patchset get converted (which should be even sooner).
