Add dummy.o to the targets list, and fill targets automatically from $(vmlinuzobjs) to avoid having to maintain two lists. When building with XZ compression copy ashldi3.c to the build directory to use a different object file for the kernel and zboot. Without this the same object file need to be build with different flags which cause a rebuild at every run. Signed-off-by:

The extended flash address needs to be subtracted from bcm_tag flash image offsets. Move this value to the bcm_tag header file. Renamed define name to consistently use bcm963xx for flash layout which should be considered a property of the board and not the SoC (i.e. bcm63xx could theoretically be used on a board without CFE or any flash).

Use the common definition of the nvram structure from the header file include/linux/bcm963xx_nvram.h instead of maintaining a separate copy. Read the version 5 size of nvram data from memory and then call the new checksum verification function from the header file. Signed-off-by:

Simon Arlott authored
Broadcom BCM963xx boards have multiple nvram variants across different SoCs with additional checksum fields added whenever the size of the nvram was extended. Add this structure as a header file so that multiple drivers can use it. Signed-off-by:

James Hogan authored
The header arch/mips/kvm/opcode.h defines a few extra opcodes which aren't in arch/mips/include/uapi/asm/inst.h. There's nothing KVM specific about them, so lets move them into inst.h where they belong and delete the header. Note that mfmcz_op is renamed to mfmc0_op to match the instruction set manual, and wait_op was already added to inst.h in commit b0a3eae2 ("MIPS: inst.h: define COP0 wait op"), merged in v3.16-rc1.

Drop the custom cache operation code definitions used by KVM for emulating guest CACHE instructions, and switch to use the existing definitions in <asm/cacheops.h>. Signed-off-by:
-
James Hogan authored
Most of the cache op codes defined in cacheops.h are split into a 2-bit cache identifier, and a 3-bit cache op code which does largely the same thing semantically regardless of the cache identifier. To allow the use of these definitions by KVM for decoding cache ops, break the definitions down into parts where it makes sense to do so, and add masks for the Cache and Op field within the cache op.

Add a few missing trap codes. [ralf@linux-mips.org: Drop removal of exception codes. I don't care what the incomplete architecture spec says; it can't change existing hardware and VCEI is supported indeed.] Signed-off-by:

James Hogan authored
Move the Cause.ExcCode trap code definitions from kvm_host.h to mipsregs.h, since they describe architectural bits rather than KVM specific constants, and change the prefix from T_ to EXCCODE_. Signed-off-by:

When calculating the offsets into the commpage for dynamically translated mtc0/mfc0 guest instructions, multiple offsetof()s are added together to find the offset of the specific register in the mips_coproc, within the commpage. Simplify each of these cases to a single offsetof() to find the offset of the specific register within the commpage. Signed-off-by:

The CAUSEB_DC and CAUSEF_DC definitions used by KVM are defined in asm/kvm_host.h, but all the other Cause register field definitions are found in asm/mipsregs.h. Lets reunite the DC bit definitions with its friends in mipsregs.h. Signed-off-by:

Some definitions in the MIPS asm/kvm_host.h are completely unused, so lets drop them. MS_TO_NS is no longer used since commit e30492bb ("MIPS: KVM: Rewrite count/compare timer emulation"). The others don't appear ever to have been used. Signed-off-by:

Joshua Henderson authored
This adds support for the Microchip PIC32 MIPS microcontroller with the specific variant PIC32MZDA. PIC32MZDA is based on the MIPS m14KEc core and boots using device tree. This includes an early pin setup and early clock setup needed prior to device tree being initialized. In additon, an interface is provided to synchronize access to registers shared across several peripherals. Signed-off-by:

This adds support for the interrupt controller present on PIC32 class devices. It handles all internal and external interrupts. This controller exists outside of the CPU core and is the arbitrator of all interrupts (including interrupts from the CPU itself) before they are presented to the CPU. The following features are supported: - DT properties for EVIC and for devices/peripherals that use interrupt lines - Persistent and non-persistent interrupt handling - irqdomain and generic chip support - Configuration of external interrupt edge polarity Signed-off-by:

The cp0_tcstatus member of struct pt_regs was removed along with the rest of SMTC in v3.16, commit b633648c ("MIPS: MT: Remove SMTC support"), however recent uprobes support in v4.3 added back a reference to it in the regoffset_table[] in ptrace.c. Remove it. Signed-off-by:

Fix the description of the microMIPS NOP16 encoding or MM_NOP16, which is not equivalent to the MIPS16 NOP instruction. This is 0x0c00 and represents the microMIPS `MOVE16 $0, $0' operation, whereas MIPS16 NOP is encoded as 0x6500, representing `MOVE $0, $16'. Also fix a typo in `mm_fp0_format' description.

Remove irrelevant content from the description of the emulation frame in `mips_dsemul', referring to bare-metal configurations. Update the text, reflecting the change made with commit ba3049ed ("MIPS: Switch FPU emulator trap to BREAK instruction."), where we switched from using an address error exception on an unaligned access to the use of a BREAK 514 instruction causing a breakpoint exception instead.
