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.

MIPS: jz4740: Rename jz4740 folders to ingenic

2020-09-18T14:35:05+00:00

Now that all the jz4740 platform code has been removed, and we're left
with only a Kconfig and the cpu-feature-overrides.h file, finalize the
cleanup process by renaming the jz4740 and include/mach-jz4740 folders
to ingenic and include/mach-ingenic.

MIPS: generic: Add support for Ingenic SoCs

2020-09-18T14:33:59+00:00

Add support for Ingenic SoCs in arch/mips/generic/.

The Kconfig changes are here to ensure that it is possible to compile
either a generic kernel that supports Ingenic SoCs, or a Ingenic-only
kernel, both using the same code base, to avoid duplicated code.

MIPS: generic: Add support for zboot

2020-09-18T14:33:06+00:00

There is no reason we can't create compressed kernels here, so select
the option SYS_SUPPORTS_ZBOOT.

MIPS: generic: Support booting with built-in or appended DTB

2020-09-18T14:32:19+00:00

The plat_get_fdt() checked that the kernel was booted using UHI before
reading the 'fw_passed_dtb' variable. However, this variable is also set
when the DT has been appended, or when it has been built into the kernel.

Support these usecases by removing the UHI check.

MIPS: generic: Init command line with fw_init_cmdline()

2020-09-18T14:31:10+00:00

The function bootcmdline_init() in arch/mips/kernel/setup.c will
populate the boot_command_line string using the parameters hardcoded in
the kernel, and those provided in the devicetree file. Then, it would
append the content of the arcs_cmdline variable, which is filled by the
board's plat_mem_setup() function.

The plat_mem_setup() function for the generic MIPS board would just copy
the current boot_command_line to arcs_cmdline, which is nonsense for two
reasons:
- the result will be appended to the boot_command_line anyway, so all it
  does is duplicate every single parameter on the command line;
- the code did not perform at all what it's supposed to, which is to
  retrieve the parameters passed by the bootloader.

Fix this by calling fw_init_cmdline() in plat_mem_setup(), which will
properly initialize arcs_cmdline to the parameters passed by the
bootloader.

MIPS: generic: Allow boards to set system type

2020-09-18T14:28:56+00:00

Check for the system_type variable in the get_system_type() function. If
non-NULL, return it as the system type.

MIPS: Kconfig: add MIPS_GENERIC_KERNEL symbol

2020-09-18T14:28:31+00:00

The MIPS_GENERIC symbol now won't select any other configuration option.
The MIPS_GENERIC_KERNEL will select all the options that the previous
MIPS_GENERIC option did select, and will select MIPS_GENERIC as well.

The whole point of this, is that it now becomes possible to compile a
kernel for a SoC supported by the arch/mips/generic/ code, without
making that kernel generic itself.

MIPS: Only include the platform file needed

2020-05-12T22:17:18+00:00

Instead of including all Platform files, we simply include the
needed one and avoid clashes with makefile variables.

MIPS: generic: Replace by

2020-02-19T18:36:07+00:00

The generic MIPS platform code is not a clock provider, and just needs
to call of_clk_init().

Hence it can include  instead of .
