2016-08-02MIPS: store the appended dtb address in a variableJonas Gorski1-2/+2
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.

2016-05-13MIPS: BMIPS: Add BCM6358 supportÁlvaro Fernández Rojas1-0/+10
BCM6358 has a shared TLB which conflicts with current SMP support, so it must be disabled for now. BCM6358 uses >= 0xfffe0000 addresses for internal registers, which need to be remapped (by using a simplified version of BRCM63xx ioremap.h). However, 0xfff80000 is a better address, since it also covers BCM3368, leaving the possibility to add it in the future.

2016-05-13MIPS: BMIPS: Add early CPU initialization codeFlorian Fainelli1-0/+1
Port the stblinux-3.3 code to perform a bunch of CPU-specific initialization, make it compatible with run-time detection of the CPU, and unroll the brcmstb-specific macros: BDEV_RB(), BDEV_UNSET. The "pref 30" disabling is done as a quirk. This is a preliminary change to allow the use of the "rotr" instruction gated by cpu_has_rixi.

Seval of-enabled machines (bmips, lantiq, xlp, pistachio, ralink) copied the arguments from dtb to arcs_command_line to prevent the kernel from overwriting them. Since there is now an option to keep the dtb arguments, default to the new option remove the "backup" to arcs_command_line in case of USE_OF is enabled, except for those platforms that still take the bootloader arguments or do not use any at all.
