| | | | | | | | | | | | | | The retry logic in ug_putc() is broken. If the TX fifo is not ready and the counter runs out it will have a value of -1 and no transfer should be attempted. Also, a counter with a value of 0 means that the TX fifo got ready in the last try and the transfer should be attempted.

* powerpc: wii: allow ioremap within the memory holeAlbert Herranz2009-12-13
| | | | | | | | | | | | | | | Enable the flag that allows a platform to ioremap memory marked as reserved. This is currently needed on the Nintendo Wii video game console due to the workaround introduced in "wii: use both mem1 and mem2 as ram". This will no longer be needed when proper discontig memory support for 32-bit PowerPC is added to the kernel.

* wii: use both mem1 and mem2 as ramAlbert Herranz2009-12-13
| | | | | | | | | | | | | | | | | | | | | | | | | The Nintendo Wii video game console has two discontiguous RAM regions: - MEM1: 24MB @ 0x00000000 - MEM2: 64MB @ 0x10000000 Unfortunately, the kernel currently does not support discontiguous RAM memory regions on 32-bit PowerPC platforms. This patch adds a series of workarounds to allow the use of the second memory region (MEM2) as RAM by the kernel. Basically, a single range of memory from the beginning of MEM1 to the end of MEM2 is reported to the kernel, and a memory reservation is created for the hole between MEM1 and MEM2. With this patch the system is able to use all the available RAM and not just ~27% of it. This will no longer be needed when proper discontig memory support for 32-bit PowerPC is added to the kernel.

| * powerpc: fix linkstation and storcenter compilation breakageGuennadi Liakhovetski2009-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 Herrenschmidt2009-03-11
|/ | | | | | | | | | | | | | | | | | | | | | 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>
