| * powerpc: fix linkstation and storcenter compilation breakageGuennadi Liakhovetski2009-03-092-70/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | Defining flash partition table in platform code is deprecated, and due to recent changes linkstation and storcenter do not compile any more with their default configurations because of undefined references to physmap_set_partitions(). Instead of fixing them by using the correct kernel configuration macro in preprocessor conditional, remove partition table definitions altogether. Instead add support for partition definition on the command-line and in device tree to the default configurations.

* | powerpc/kconfig: Kill PPC_MULTIPLATFORMBenjamin Herrenschmidt2009-03-111-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | CONFIG_PPC_MULTIPLATFORM is a remain of the pre-powerpc days and isn't really meaningful anymore. It was basically equivalent to PPC64 || 6xx. This removes it along with the following changes: - 32-bit platforms that relied on PPC32 && PPC_MULTIPLATFORM now rely on 6xx which is what they want anyway. - A new symbol, PPC_BOOK3S, is defined that represent compliance with the "Server" variant of the architecture. This is set when either 6xx or PPC64 is set and open the door for future BOOK3E 64-bit. - 64-bit platforms that relied on PPC64 && PPC_MULTIPLATFORM now use PPC64 && PPC_BOOK3S - A separate and selectable CONFIG_PPC_OF_BOOT_TRAMPOLINE option is now used to control the use of prom_init.c Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

* powerpc: fix i2c on PPC linkstation / kurobox machinesGuennadi Liakhovetski2008-10-281-0/+14
| | | | | | | | | | The i2c bus defn is broken on linkstation / kurobox machines since at least 2.6.27. Fix it. Also remove CONFIG_SERIAL_OF_PLATFORM, which, if enabled, breaks the serial console after the "console handover: boot [udbg0] -> real [ttyS1]" message.

* powerpc: Move memory size print into common show_cpuinfo for 32-bitBecky Bruce2008-10-222-6/+0Star
| | | | | | | | | | | Most of the platforms were printing the size of the memory in their show_cpuinfo implementations. This moves that to the common show_cpuinfo, so that all 32-bit platforms will now print the size of memory. I also update the code to deal with the fact that total_memory is now a phys_addr_t.

| | | | | | | | | | | | | | | | | | Commit 69331af, "Fixes and cleanups for earlyprintk aka boot console", resulted in printk output prior to the initialization of the mpsc console driver not being printed. That commit causes the mpsc's CON_PRINTBUFFER flag to be cleared since udbg should have printed the previous output. I guess we can no longer ignore udbg. :) This patch provides udbg_putc() and udbg_getc() functions for the Marvell mv64x60 chips. These functions are enabled if an mv64x60 port is to be used as the console as determined from the device tree. Signed-off-by: Dale Farnsworth <dale@farnsworth.org> Acked-by: Mark A.
