The sead3-mtd.o is built for obj-y -- and hence this code is always present. It will never be modular, so using module_init as an alias for __initcall can be somewhat misleading. Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be a worse thing. Note that direct use of __initcall is discouraged, vs. one of the priority categorized subgroups. As __initcall gets mapped onto device_initcall, our use of device_initcall directly in this change means that the runtime impact is zero -- it will remain at level 6 in initcall ordering. We also fix a missing semicolon, which this change uncovers. Signed-off-by:

Loongson-1 is a 32-bit MIPS CPU and Loongson-2/3 are 64-bit MIPS CPUs, and both Loongson-2/3 has the same PRID IMP filed (0x6300). As a result, renaming PRID_IMP_LOONGSON1 and PRID_IMP_LOONGSON2 to PRID_IMP_LOONGSON_32 and PRID_IMP_LOONGSON_64 will make more sense. Signed-off-by:

Commit c24a8a7a ("MIPS: Netlogic: Add MSI support for XLP") added "select ARCH_SUPPORTS_MSI". But the Kconfig symbol ARCH_SUPPORTS_MSI was already removed in v3.12, so that select is a nop. Drop it. Signed-off-by:

74K/proAptiv share the same event/cache maps. So it's better to change the names of the existing mipsxx74Kcore_[event|cache]_map. Signed-off-by:

The HAVE_PWM symbol is only for legacy platforms that provide the PWM API without using the generic framework. The jz4740 platform uses the generic PWM framework, after the commit "f6b8a570 pwm: Add Ingenic JZ4740 support". Signed-off-by:

Commit 0046be10e0c502705fc74d91408eba13a73bc201 ("mips: delete non-required instances of include <linux/init.h>") inadvertently removed an include that was actually correct. Restore it. Note that it gets init.h implicitly anyway, so this is largely a cosmetic fixup; no build regressions were caused by this. Signed-off-by: -

Add a few Belkin F7Dxxxx entries, with F7D4401 sourced from online documentation and the "F7D7302" being observed. F7D3301, F7D3302, and F7D4302 are reasonable guesses which are unlikely to cause mis-detection. Signed-off-by:

The Linksys WRT54G/GS/GL family uses the same boardtype numbers, and the same gpio configuration. The boardtype numbers are changing with the hardware versions, but these hardware numbers are different or each model. Detect them all as one device, this also worked in OpenWrt. Signed-off-by:

The M5150 core is a 32-bit MIPS RISC which implements the MIPS Architecture Release-5 in a 5-stage pipeline. In addition, it includes the MIPS Architecture Virtualization Module that enables virtualization of operating systems, which provides a scalable, trusted, and secure execution environment.

The previous NR_CPUS=2 default is not an optimal default for current Malta setups where it is common to have more than 2 CPUs available. It makes sense to increase this to a number which covers all common setups currently in use, such that all of those cores are usable. 8 seems to fit that description. If the user has less than 8 CPUs & they wish to have a more optimal kernel they can simply reduce this in their config. It makes sense for the default to work on as many systems as possible.

For Malta defconfigs which may run on an SMP configuration without hardware cache anti-aliasing, a 16KB page size is a safer default. Most notably at the moment it will avoid cache aliasing issues for multicore proAptiv systems. Signed-off-by:

This patch simply regenerates the malta defconfigs such that they don't change after being used & saved as a defconfig again. ie. it is the result of running the following: for cfg in arch/mips/configs/malta*; do ARCH=mips make `basename ${cfg}` ARCH=mips make savedefconfig mv -v defconfig ${cfg} done Signed-off-by: -

The au1xxx-ide driver isn't any faster than pata_platform since it spends a lot of time busy waiting for DMA to finish; faster PIO/DMA modes only work on the db1200 with a certain cpu speed, UDMA is broken, and finally the old IDE layer is on death row, so time to switch to the newer ATA layer.

Shift System Controller memory mapping to 0x80000000 Signed-off-by:

Markos Chandras authored
Use a Malta specific function to free the init section once the kernel has booted. When operating in EVA mode, the physical memory is shifted to 0x80000000. Kernel is loaded into 0x80000000 (virtual) so the offset between physical and virtual addresses is 0. Signed-off-by: -

PHYS_OFFSET is used to denote the physical start address of the first bank of RAM. When the Malta board is in EVA mode, the physical start address of RAM is shifted to 0x80000000 so it's necessary to use this macro in order to make the code EVA agnostic. Signed-off-by: -

The 'ememsize' variable is used to denote the real RAM which is present on the Malta board. This is different compared to 'memsize' which is capped to 256MB. The 'ememsize' is used to get the actual physical memory when setting up the Malta memory layout. This only makes sense in case the core operates in the EVA mode, and it's ignored otherwise.

Markos Chandras authored
The Malta board aliases 0x80000000 - 0xffffffff to 0x00000000 - 0x7fffffff ignoring the 256 MB IO hole in 0x10000000. The physical memory is shifted to 0x80000000 so up to 2GB can be used. Kuseg is expanded to 3GB (due to board limitations only 2GB can be accessed) and lowmem (kernel space) is expanded to 2GB. The Segment Control registers are programmed as follows: Virtual memory Physical memory Mapping 0x00000000 - 0x7fffffff 0x80000000 - 0xfffffffff MUSUK (kuseg) 0x80000000 - 0x9fffffff 0x00000000 - 0x1ffffffff MUSUK (kseg0) 0xa0000000 - 0xbf000000 0x00000000 - 0x1ffffffff MUSUK (kseg1) 0xc0000000 - 0xdfffffff - MK (kseg2) 0xe0000000 - 0xffffffff - MK (kseg3) The location of exception vectors remain the same since 0xbfc00000 (traditional exception base) still maps to 0x1fc00000 physical.

There is a chance for the secondary cache to have memory aliases. This can happen if the bootloader is in a non-EVA mode (or even in EVA mode but with different mapping from the kernel) and the kernel switching to EVA afterwards. It's best to flush the icache to avoid having the secondary CPUs fetching stale data from it. Signed-off-by:

A core in EVA mode can have any possible segment mapping, so the default free_initmem_default() function may not always work as expected. Therefore, add a callback that platforms can use to free up the init section. Signed-off-by: -
