Some hardware blocks attached to the OCTEON bootbus run asynchronously to accesses from the CPUs. These include MMC/SD host, CF(when using DMA), and NAND controller. A bus error, or corrupt data may occur if a CPU is trying to access a bootbus connected device at the same time the bus is running asynchronous operations. To work around these problems we add this semaphore that must be acquired before initiating bootbus activity. Subsequent patches will add users for this.

Pull MIPS updates from Ralf Baechle: "This is the main pull request for MIPS: - a number of fixes that didn't make the 3.19 release. - a number of cleanups. - preliminary support for Cavium's Octeon 3 SOCs which feature up to 48 MIPS64 R3 cores with FPU and hardware virtualization. - support for MIPS R6 processors. Revision 6 of the MIPS architecture is a major revision of the MIPS architecture which does away with many of original sins of the architecture such as branch delay slots. This and other changes in R6 require major changes throughout the entire MIPS core architecture code and make up for the lion share of this pull request. - finally some preparatory work for eXtendend Physical Address support, which allows support of up to 40 bit of physical address space on 32 bit processors" [ Ahh, MIPS can't leave the PAE brain damage alone.

2014-11-24MIPS: Fix microMIPS LL/SC immediate offsetsMaciej W. Rozycki1-1/+3
In the microMIPS encoding some memory access instructions have their immediate offset reduced to 12 bits only. That does not match the GCC `R' constraint we use in some places to satisfy the requirement, resulting in build failures like this: {standard input}: Assembler messages: {standard input}:720: Error: macro used $at after ".set noat" {standard input}:720: Warning: macro instruction expanded into multiple instructions Fix the problem by defining a macro, `GCC_OFF12_ASM', that expands to the right constraint depending on whether microMIPS or standard MIPS code is produced. Also apply the fix to where `m' is used as in the worst case this change does nothing, e.g. where the pointer was already in a register such as a function argument and no further offset was requested, and in the best case it avoids an extraneous sequence of up to two instructions to load the high 20 bits of the address in the LL/SC loop. This reduces the risk of lock contention that is the higher the more instructions there are in the critical section between LL and SC. Strictly speaking we could just bulk-replace `R' with `ZC' as the latter constraint adjusts automatically depending on the ISA selected. However it was only introduced with GCC 4.9 and we keep supporing older compilers for the standard MIPS configuration, hence the slightly more complicated approach I chose. The choice of a zero-argument function-like rather than an object-like macro was made so that it does not look like a function call taking the C expression used for the constraint as an argument. This is so as not to confuse the reader or formatting checkers like `checkpatch.pl' and follows previous practice. Signed-off-by: Maciej W. Rozycki <macro@codesourcery.com> Signed-off-by: Steven J.

2014-08-02MIPS: OCTEON: cvmx-bootinfo: add D-Link DSR-1000NAaro Koskinen1-0/+2
Add a definition for D-Link DSR-1000N router. The bootloader on this board supplies 20006 in the bootinfo; the enum CVMX_BOARD_TYPE_CUST_DSR1000N comes from the GPL sources of the board.

2014-05-23MIPS: Octeon: Remove checks for CONFIG_CAVIUM_GDBPaul Bolle1-1/+0
Three checks for CONFIG_CAVIUM_GDB were added in v2.6.29. But the Kconfig symbol CAVIUM_GDB was never added to the tree. Remove these checks. Also remove the last reference to octeon_get_boot_debug_flag(). There is no definition of that function anyway.

Enable interfaces on EdgeRouter Lite. Tested with cavium_octeon_defconfig and busybox shell. DHCP & ping works with eth0, eth1 and eth2. The board type "UBNT_E100" is taken from the sources of the vendor kernel shipped with the product.

Pull MIPS updates from Ralf Baechle: o Add basic support for the Mediatek/Ralink Wireless SoC family. o The Qualcomm Atheros platform is extended by support for the new QCA955X SoC series as well as a bunch of patches that get the code ready for OF support. o Lantiq and BCM47XX platform have a few improvements and bug fixes. o MIPS has sent a few patches that get the kernel ready for the upcoming microMIPS support. o The rest of the series is made up of small bug fixes and cleanups that relate to various parts of the MIPS code. The biggy in there is a whitespace cleanup. After I was sent another set of whitespace cleanup patches I decided it was the time to clean the whitespace "issues" for once and and that touches many files below arch/mips/. Fix up silly conflicts, mostly due to whitespace cleanups. * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (105 commits) MIPS: Quit exporting kernel internel break codes to uapi/asm/break.h MIPS: remove broken conditional inside vpe loader code MIPS: SMTC: fix implicit declaration of set_vi_handler MIPS: early_printk: drop __init annotations MIPS: Probe for and report hardware virtualization support.
