SSB_EMBEDDED needs functions from driver_pcicore which are only available if SSD_DRIVER_HOSTMODE is selected so make it depend on that symbol. Fixes the following linking problem: drivers/ssb/embedded.c:202: undefined reference to `ssb_pcicore_plat_dev_init' drivers/built-in.o: In function `ssb_pcibios_map_irq': drivers/ssb/embedded.c:247: undefined reference to `ssb_pcicore_pcibios_map_irq' Signed-off-by:

The ISA exception bit selects whether exceptions are taken in classic or microMIPS mode. This bit is Config3.ISAOnExc and was improperly defined as bits 16 and 17 instead of just bit 16. A new function was added so that platforms could set this bit when running a kernel compiled with only microMIPS instructions. Signed-off-by:

BMIPS43xx CPUs have two hardware threads, and on some SoCs such as 3368, the bootloader has configured the system to boot from TP1 instead of the more usual TP0. Create the physical to logical CPU mapping to cope with that, do not remap the software interrupts to be cross CPUs such that we do not have to do use the logical CPU mapping further down the code, and finally, reset the slave TP1 only if booted from TP0.

As Jonas Gorske said in his patch: Disable cpu_has_mmips for everything but SEAD3 and MALTA. Most of these platforms are from before the micromips introduction, so they are very unlikely to implement it. Reduces an -Os compiled, uncompressed kernel image by 8KiB for BCM63XX. This patch taks a different approach than his, we gate the runtime test for microMIPS by the config symbol SYS_SUPPORTS_MICROMIPS. Signed-off-by:

Prepare of a next patch which will call tlbmiss_handler_setup_pgd on microMIPS. MicroMIPS complains if the called code s not in the .text section. To fix this we generate code into space reserved in arch/mips/mm/tlb-funcs.S While there, move the rest of the generated functions (handle_tlbl, handle_tlbs, handle_tlbm) to the same file.

MIPS I is the ancestor of all MIPS ISA and architecture variants. Anything ever build in the MIPS empire is either MIPS I or at least contains MIPS I. If it's running Linux, that is. So there is little point in having cpu_has_mips_1 because it will always evaluate as true - though usually only at runtime. Thus there is no point in having the MIPS_CPU_ISA_I ISA flag, so get rid of it. Little complication: traps.c was using a test for a pure MIPS I ISA as a test for an R3000-style cp0. To deal with that, use a check for cpu_has_3kex or cpu_has_4kex instead. cpu_has_3kex is a new macro. At the moment its default implementation is !cpu_has_4kex but this may eventually change if Linux is ever going to support the oddball MIPS processors R6000 and R8000 so users of either of these macros should not make any assumptions.

We will use 8250_dw instead. Signed-off-by:

David Daney authored
A few differences needed by OCTEON: o These are DWC UARTS, but have USR at a different offset. o Internal SoC buses require reading back from registers to maintain write ordering. o 8250 on OCTEON appears with 64-bit wide registers, so when using readb/writeb in big endian mode we have to adjust the membase to hit the proper part of the register. o No UCV register, so we hard code some properties. Because OCTEON doesn't have a UCV register, I change where dw8250_setup_port(), which reads the UCV, is called by pushing it in to the OF and ACPI probe functions, and move unchanged dw8250_setup_port() earlier in the file.

Add the firmware header format which is used by Broadcom Cable Modem SoCs such as the BCM3368 SoC. We export the bcm_hcs firmware format structure because it is used by user-land tools to create firmware images for these SoCs and will later be used by a corresponding MTD parser. Signed-off-by:

The Broadcom BCM3368 Cable Modem SoC is extremely similar to the existing BCM63xx DSL SoCs, in particular BCM6358, therefore little effort in the existing code base is required to get it supported. This patch adds support for the following on-chip peripherals: - two UARTS - GPIO - Ethernet - SPI - PCI - NOR Flash The most noticeable difference with 3368 is that it has its peripheral register at 0xfff8_0000 we check that separately in ioremap.h. Since 3368 is identical to 6358 for its clock and reset bits, we use them verbatim. Signed-off-by:

Enabling BOOT_RAW is mandatory to get a binary image (objcopy from ELF to binary) to work. This does not affect the ELF kernels which are used by CFE on BCM63XX DSL platforms, but is going to be necessary to support BCM63XX on Cable Modem chips such as BCM3368. Signed-off-by:

For non-SMP, uses the new random canary value that is stored in the task struct whenever a new task is forked. Based on ARM version in df0698be and subject to the same limitations: the variable GCC expects, __stack_chk_guard, is global, so this will not work on SMP. Quoting Nicolas Pitre <nico@fluxnic.net>: "One way to overcome this GCC limitation would be to locate the __stack_chk_guard variable into a memory page of its own for each CPU, and then use TLB locking to have each CPU see its own page at the same virtual address for each of them."

Markos Chandras authored
When building with -fstack-protector, gcc emits the __stack_chk_guard and __stack_chk_fail symbols to check for stack stability. These symbols are defined in vmlinux but the generated vmlinux.bin that is used to create the compressed vmlinuz image has no symbol table so the linker can't find these symbols during the final linking phase. As a result of which, we need either to redefine these symbols just for the compressed image or drop the -fstack-protector option when building the compressed image. This patch implements the latter of two options. Fixes the following linking problem: dbg.c:(.text+0x7c): undefined reference to `__stack_chk_guard' dbg.c:(.text+0x80): undefined reference to `__stack_chk_guard' dbg.c:(.text+0xd4): undefined reference to `__stack_chk_guard' dbg.c:(.text+0xec): undefined reference to `__stack_chk_fail' [ralf@linux-mips.org: I'm applying this before the patch that actually adds stack protector support for MIPS. This means, it will not be possible to trigger above error message with any commit from the tree but rather they are what one would hit without this commit.] Signed-off-by:

The PMC MSP71XX gpio drivers were added in v2.6.28, see commit 9fa32c6b ("MIPS: PMC MSP71XX gpio drivers"). They are only built if CONFIG_HAVE_GPIO_LIB is set. But the Kconfig symbol HAVE_GPIO_LIB was already removed in v2.6.27, see commit 7444a72e ("gpiolib: allow user-selection"). So these drivers were never buildable. Perhaps no-one noticed because there are no in tree users of msp71xx_init_gpio() and msp71xx_init_gpio_extended(). Anyhow, these drivers can safely be removed. Signed-off-by:
