Hello,
For the record this the second version of the series adding the support of 2 SoCs: Ocelot and Luton from Microsemi. Both of them belongs to the same family Vcore III.
We found them on various advanced switches product.
The support for Ocelot already have been submit to Linux, but not yet the Luton support.
Since the v1 many changes had been done:
- a big clean-up for indentation and some style issue - usage of the clrsetbits family functions where it was possible - split the patches for Ocelot and Luton - add a new patch to introduce the icache_lock function which was in the mscc directory in the first version - remove more unused define in the platform header files - use the automatic cache size detection instead of hard coding it - reduce the tlb init to only two entries for the IO as needed by the kernel - remove the interrupt disabling - fix the ddr init for luton
Gregory CLEMENT (7): MIPS: move create_tlb() in an proper header: mipsregs.h MIPS: Allow to prefetch and lock instructions into cache MSCC: add support for Ocelot SoCs MSCC: add support for Luton SoCs MSCC: add board support for the Ocelots based evaluation boards MSCC: add board support for the Luton based evaluation board MIPS: bootm: Add support for Vcore III linux kernel
