2009-02-13powerpc/ps3: Move ps3_mm_add_memory to device_initcallGeoff Levand
Change the PS3 hotplug memory routine ps3_mm_add_memory() from a core_initcall to a device_initcall. core_initcall routines run before the powerpc topology_init() startup routine, which is a subsys_initcall, resulting in failure of ps3_mm_add_memory() when CONFIG_NUMA=y. When ps3_mm_add_memory() fails the system will boot with just the 128 MiB of boot memory Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2009-01-29powerpc/5200: Bugfix for PCI mapping of memory and IMMRGrant Likely
This patch ensures that memory gets properly mapped into the PCI address space. Without this patch, the memory window BAR is left at whatever value happened to be loaded into the BAR when Linux was booted. Without this patch, memory could end up getting mapped at any of the 1G address boundaries instead of at '0' where Linux expects it. Similarly, this patch also ensures that the internally memory mapped registers (IMMR) are mapped to the correct PCI address range. Without this patch, PCI appears to work correctly until a PCI device is inserted which DMAs into memory.

2009-01-13powerpc/powermac: Fix occasional SMP boot failureBenjamin Herrenschmidt
The PowerMac kernel occasionally fails to bring up the secondary CPUs on SMP, the trigger factor seem to be fairly random and related to location of code and data. This appears to be due to the initial loading of the TOC value by the secondary processor which now happens before we clear HID4:RM_CI (Real Mode Cache Invalidate). This bit should really be cleared before we do any load or store other than fetching code. This fix works based on the assumption that all SMP 64-bit PowerMacs use variants of the 970, which fortunately is true, by explicitely clearing that bit, adding an slbia for good measure as RM_CI mode is known to create bogus ERAT entries. I also removed some spurrious debug output that was left enabled by mistake while at it. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2008-12-30powerpc: Implement GPIO driver for simple memory-mapped banksAnton Vorontsov
The driver supports very simple GPIO controllers, that is, when a controller provides just a 'data' register. Such controllers may be found in various BCSRs (Board's FPGAs used to control board's switches, LEDs, chip-selects, Ethernet/USB PHY power, etc). So far we support only 1-byte GPIO banks. Support for other widths may be implemented when/if needed. p.s. To avoid "made up" compatible entries (like compatible = "simple-gpio"), boards must call simple_gpiochip_init() to pass the compatible string.
