* docs: arm: convert docs to ReST and rename to *.rstMauro Carvalho Chehab2019-07-151-1/+1
| | | | | | | | | | | | | | | | | | Converts ARM the text files to ReST, preparing them to be an architecture book. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

* MIPS: bmips: remove unnecessary call to register "simple-bus"Rob Herring2018-06-241-7/+0
| | | | | | | | | | | | | | | | | The DT core will register "simple-bus" by default, so it is not necessary for arch specific code to do so unless there are custom match entries, auxdata or parent device. Neither of those apply here, so remove the call.

* MIPS: store the appended dtb address in a variableJonas Gorski2016-08-021-2/+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.

* MIPS: BMIPS: Add BCM6358 supportÁlvaro Fernández Rojas2016-05-131-0/+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.

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.

* MIPS: Make MIPS_CMDLINE_DTB defaultJonas Gorski2015-11-111-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
