2018-12-19MIPS: Allow to prefetch and lock instructions into cacheGregory CLEMENT
This path add a new helper allowing to prefetch and lock instructions into cache. This is useful very early in the boot when no RAM is available yet. Signed-off-by: Gregory CLEMENT <gregory.clement@bootlin.com>
2018-12-19MIPS: move create_tlb() in an proper header: mipsregs.hGregory CLEMENT
Export create_tlb() as an inline function in mipsregs.h. It allows to remove the declaration of the function from the board files. Then it will allow also to use this function very early in the boot when the stack is not usable. Signed-off-by: Gregory CLEMENT <gregory.clement@bootlin.com>
2018-12-19MIPS: remove local_irq_[save|restore] from CP0 macrosDaniel Schwierzeck
With moving write_on_tlb() to arch/mips/include/asm/mipsregs.h there are now compiler warnings when some generic code includes asm/io.h. This happens for example when enabling OF live tree. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
2018-12-19mips: mt76xx: Flush d-cache in arch_misc_init() to solve d-cache issuesStefan Roese
It has been noticed, that sometimes the d-cache is not in a "clean-state" when U-Boot is running on MT7688. This was detected when using the ethernet driver (which uses d-cache) and a TFTP command does not complete. Flushing the complete d-cache (again?) here seems to fix this issue.

2018-12-19mips: xilfpga: fix DTC warningsDaniel Schwierzeck
This fixes following DTC warning: arch/mips/dts/nexys4ddr.dtb: Warning (compatible_is_string_list): /ethernet@10e00000/mdio/phy@1:compatible: property is not a string list As upstream DTS in Linux doesn't have the offending property, simply remove it to fix the warning.

2018-12-19mips: ath79: fix DTC warningsDaniel Schwierzeck
Remove all interrupt nodes that cause warnings regarding a missing interrupt parent. There are no interrupt controller nodes defined and the device trees don't match the ones in Linux anymore. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
