MIPS: pic32: treat port as signed integer get_port_from_cmdline() returns an int, yet is assigned to a char, which is wrong in its own right, but also, with char becoming unsigned, this poses problems, because -1 is used as an error value. Further complicating things, fw_init_early_console() is only ever called with a -1 argument. Fix this up by removing the unused argument from fw_init_early_console() and treating port as a proper signed integer. Cc: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Signed-off-by: Jason A.

MIPS: move from strlcpy with unused retval to strscpy Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used.

MIPS: Use address-of operator on section symbols When building xway_defconfig with clang: arch/mips/lantiq/prom.c:82:23: error: array comparison always evaluates to true [-Werror,-Wtautological-compare] else if (__dtb_start != __dtb_end) ^ 1 error generated. These are not true arrays, they are linker defined symbols, which are just addresses. Using the address of operator silences the warning and does not change the resulting assembly with either clang/ld.lld or gcc/ld (tested with diff + objdump -Dr). Do the same thing across the entire MIPS subsystem to ensure there are no more warnings around this type of comparison.

MIPS: store the appended dtb address in a variable 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: Add support for PIC32MZDA platform This adds support for the Microchip PIC32 MIPS microcontroller with the specific variant PIC32MZDA. PIC32MZDA is based on the MIPS m14KEc core and boots using device tree. This includes an early pin setup and early clock setup needed prior to device tree being initialized. In additon, an interface is provided to synchronize access to registers shared across several peripherals.
