MIPS: replace add_memory_region with memblock

2020-10-12T10:01:36+00:00

add_memory_region was the old interface for registering memory and was already changed to used memblock internaly. Replace it by directly calling memblock functions. Signed-off-by: Thomas Bogendoerfer

MIPS: Ingenic: Add system type for new Ingenic SoCs.

2020-09-27T08:57:27+00:00

Add JZ4775, X1000E, X2000, and X2000E system type for cat /proc/cpuinfo to give out JZ4775, X1000E, X2000 and X2000E. Signed-off-by: 周琰杰 (Zhou Yanjie) Reviewed-by: Paul Cercueil Signed-off-by: Thomas Bogendoerfer

MIPS: X2000: Add X2000 system type.

2020-07-24T09:13:57+00:00

1.Add "PRID_COMP_INGENIC_13" and "PRID_IMP_XBURST2" for X2000. 2.Add X2000 system type for cat /proc/cpuinfo to give out X2000. Signed-off-by: 周琰杰 (Zhou Yanjie) Signed-off-by: Thomas Bogendoerfer

MIPS: ingenic: Use enum instead of macros for Ingenic SoCs

2020-07-16T08:47:30+00:00

Use an enum instead of macros to represent the various versions of the Ingenic SoCs, and add some of the SoC versions that were previously missing. Signed-off-by: Paul Cercueil Signed-off-by: Thomas Bogendoerfer

MIPS: Remove PMC MSP71xx platform

No (active) developer owns this hardware, so let's remove Linux support. Signed-off-by: Thomas Bogendoerfer

MIPS: Cleanup code about plat_mem_setup()

2020-04-21T14:07:14+00:00

In the current code, plat_mem_setup() is called by arch_mem_init() instead of setup_arch() and has been declared in asm/bootinfo.h, so modify the code comment to reflect the reality and remove the useless duplicate declartion in arch/mips/kernel/setup.c.

MIPS: X1830: Add X1830 system type.

2020-01-09T17:48:42+00:00

1.Add X1830 system type for cat /proc/cpuinfo to give out X1830. 2.Change "PRID_IMP_XBURST" to "PRID_IMP_XBURST_REV1" and add a new "PRID_IMP_XBURST_REV2" for new Ingenic CPUs which has XBurst with MXU2 SIMD ISA. Notice: 1."PRID_IMP_XBURST_REV2" is corresponds to the latest XBurst processor with 128bit MXU2 SIMD instruction set, not the upcoming XBurst2 processor. This version of the processors fixes issues such as BTB and HPTLB. 2.In order to simplify and reuse the code, the "c->cputype" and the "c->writecombine" and the "__cpu_name[cpu]" in the original "PRID_IMP_XBURST" (now is "PRID_IMP_XBURST_REV1") are removed, and the corresponding settings are abtained through fall-through to "PRID_IMP_XBURST_REV2", which will cause the name that was previously mistakenly called "JZRISC" to become to the real name "XBurst".

MIPS: SGI-IP22/28: Use PROM for memory detection

2019-10-09T21:55:57+00:00

EARLY_PRINTK uses ArcWrite (via prom_putchar) on IP22/28, which needs to not mess up PROMs data structures. ARC PROM gives out a list of memory chunks, which are used and which are free. This fixes the problem of not working early printk. By using XKPHYS spaces more than 256MB memory on Indigo2 R4k machines is working now, too.

MIPS: init: Drop boot_mem_map

2019-08-23T14:42:40+00:00

boot_mem_map was introduced very early and cannot handle memory maps with nid. Nowadays, memblock can exactly replace boot_mem_map. Detect pfn info and setup resources with memblock maps.
