MIPS: X1830: Add X1830 system type.

2020-01-09T17:48:42Z

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

2019-10-09T21:55:57Z

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

2019-08-23T14:42:40Z

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.

mips: Add reserve-nomap memory type support

2019-05-02T18:27:11Z

It might be necessary to prevent the virtual mapping creation for a requested memory region. For instance there is a "no-map" property indicating exactly this feature. In this case we need to not only reserve the specified region by pretending it doesn't exist in the memory space, but completely remove the range from system just by removing it from memblock. The same way it's done in default early_init_dt_reserve_memory_arch() method.

MIPS: store the appended dtb address in a variable

2016-08-02T12:00:16Z

Instead of rewriting the arguments to match the UHI spec, store the address of a appended or UHI supplied dtb in fw_supplied_dtb. That way the original bootloader arugments are kept intact while still making the use of an appended dtb invisible for mach code. Mach code can still find out if it is an appended dtb by comparing fw_arg1 with fw_supplied_dtb.

MIPS: Introduce plat_get_fdt a platform API to retrieve the FDT

2016-05-13T12:02:03Z

Early access to the kernel command line requires early access to the FDT for platforms which pass the command line within the device tree. There was no common way to retrieve the location of the FDT without incurring side effects, such as plat_mem_setup which, on Malta at least, initializes a bunch of other stuff. This patch adds plat_get_ftd() for IMG platforms.
