2012-11-20MIPS: BCM63XX: fix BCM6345 clocks bitsFlorian Fainelli
BCM6345 has an intermediate 16-bits wide test control register between the peripheral identifier register, and its clock control register is only 16-bits wide contrary to other platforms where it is 32-bits wide. By shifting all clocks bits by 16-bits to the left we ensure they get written to the proper clock control register, without adding specific BCM6345 handling in the clock code.

2012-11-09MIPS: Netlogic: Support for XLR/XLS Fast Message NetworkGanesan Ramalingam
On XLR/XLS, the cpu cores communicate with fast on-chip devices (e.g. network accelerator, security engine etc.) using the Fast Messaging Network(FMN). The FMN queues and credits needs to be configured and intialized before it can be used. The co-processor 2 on XLR/XLS CPU cores has registers for FMN access, and the XLR/XLS has custom instructions for sending and loading messages. The FMN can deliver also per-cpu interrupts when messages are available at the CPU. This patch adds FMN initialization, adds interrupt setup and handling, and also provides support for sending and receiving FMN messages.

2012-11-09MIPS: BCM47xx: sprom: read values without prefix as fallbackHauke Mehrtens
There are bcma based devices like the Linksys E2000 out there, which do have one ieee80211 core, but no PCIe core and they are using no prefixes for the sprom. In addition some values like boardtype are stored without a prefix for the main SoC chip also when they have an additional PCIe wifi chip with an own boardtype var on some devices. The Ethernet addresses are now also read out correctly without a prefix so calling bcm47xx_fill_sprom_ethernet is not needed any more.

2012-11-09MIPS: BCM47XX: improve memory size detectionHauke Mehrtens
The memory size is detected by finding a place where it repeats in memory. Currently we are just checking when the function prom_init is seen again, but it is better to check for a bigger part of the memory to decrease the chance of wrong results. This should fix a problem we saw in OpenWrt, where the detected available memory decreed on some devices when doing a soft reboot.

2012-11-09MIPS: Move processing of coherency kernel parameters earlierShane McDonald
Commit 97ce2c88f9ad42e3c60a9beb9fca87abf3639faa (jump-label: initialize jump-label subsystem much earlier) caused MIPS to break, so this was resolved with commit 6650df3c380e0db558dbfec63ed860402c6afb2a (MIPS: Move cache setup to setup_arch().). Unfortunately, after this commit, the coherency kernel parameters, cca and coherentio, are no longer processed before their values are used. This patch fixes this problem by marking them as early_param, which results in them being processed before they are needed.

2012-11-09mips/octeon: 16-Bit NOR flash was not being detected during bootCharles Hardin
The cavium code assumed that all NOR on the boot bus was an 8-bit NOR part and hardcoded the bankwidth.

The kernel_thread() changes for FRV don't work, and FRV fails to boot, starting with: commit 02ce496f152df87be081a64796498942c433a2fd Author: Al Viro <viro@zeniv.linux.org.uk> Date: Tue Sep 18 22:18:51 2012 -0400 Subject: frv: split ret_from_fork, simplify kernel_thread() a lot The problem is that the userspace registers are completely cleared when a kernel thread is created and all subsequent user threads are then copied from that. Unfortunately, however, the TBR and PSR registers are restored from the pt_regs and the values they should be set to are clobbered by the memset. Instead, copy across the old user registers as normal, and then merely alter GR8 and GR9 in it if we're going to execute a kernel thread. Signed-off-by: David Howells <dhowells@redhat.com>
2012-11-02FRV: Fix the preemption handlingDavid Howells
Fix the preemption handling in FRV code where the PREEMPT_ACTIVE value is incorrectly loaded into the threadinfo flags rather than the threadinfo preemption count. Unfortunately, the code cannot be simply converted to use preempt_schedule_irq() as is because FRV uses virtual interrupt disablement to cut down on the cost of actually disabling interrupts and thus local_irq_enable() doesn't actually enable interrupts.
