This fixes: {standard input}: Assembler messages: {standard input}:145: Error: opcode not supported on this processor: vr5000 (mips4) `clz $2,$2' {standard input}:920: Error: opcode not supported on this processor: vr5000 (mips4) `clz $7,$9' {standard input}:1797: Error: opcode not supported on this processor: vr5000 (mips4) `clz $7,$7' {standard input}:1851: Error: opcode not supported on this processor: vr5000 (mips4) `clz $7,$7' {standard input}:2831: Error: opcode not supported on this processor: vr5000 (mips4) `clz $7,$7' {standard input}:4209: Error: opcode not supported on this processor: vr5000 (mips4) `clz $7,$7' {standard input}:4329: Error: opcode not supported on this processor: vr5000 (mips4) `clz $2,$2' make[2]: *** [arch/mips/mm/tlbex.o] Error 1 which triggered due to a regression causing the file to be built with `-march=r5000' rather than `-march=sb1', fixed separately. Nevertheless the error should not happen, the other uses of CLZ are appropriately guarded. This change copies the arrangement from one of those other places. Signed-off-by:Maciej W.

Code in a switch statement in probe_pcache checks the CPU type twice unnecessarily for processor implementations that have the alias removal feature reported by the CP0 Config7.AR and Config7.IAR bits. This change rewrites the affected fragment avoiding the extraneous check and improving readability. Signed-off-by:

The generic version uses a variable length of u32 registers instead of u32/u64. This allows easier support for "wider" registers without having to rewrite everything. This "generic" version is as fast as the old version in the best case (i == next set bit), and twice as fast in the worst case in 64 bits. Using a macro was chosen over a (forced) inline version because gcc generated more compact code with the macro. The change from (signed) int to unsigned int for i and to_call was intentional as the value can be only between 0 and (width - 1) anyway, and allowed gcc to optimise the code a bit further.

We are using the mips counters as the clock source, so we need to ensure they are synced, else e.g. gettimeofday will return different values depending on which core it was run. Observed difference was about 8 seconds, causing ~8 seconds ping or time running backwards for some programs. Signed-off-by:

Add use of the common clock framework to set and enable the 48MHz clock source for the onchip OHCI and UDC blocks. Tested on a DB1500. (Au1200 and Au1300 use an external 48MHz crystal). Signed-off-by:

This patch introduces common clock framework integration for all configurable on-chip clocks on Alchemy chips: - 2 or 3 PLLs which generate integer multiples of the root rate 12MHz, - 6 dividers which take one of the 3 PLLs as input and divide their rate by either multiples of 2 or 1 (Au1300). - another bank of up to 6 muxes which take either one of the 6 above dividers or one of the PLLs directly and divide their rate further by 1, 2, 3 or 4. - a few other sources which are used by onchip peripherals and are informational. This implementation will take the clock tree as it was set up by boot firmware: all in-kernel boards should continue to work without having to set up the clock tree in board code. CLK_IGNORE_DISABLED will be removed once all drivers have been converted. Signed-off-by:

This patch changes the static memory controller registers to offsets from base, prefixes them with AU1000_ to avoid silent failures due to changed addresses and introduces helpers to access them. No functional changes, comparing assembly of a few select functions shows no differences. Signed-off-by:
