2012-07-24MIPS: BCM63XX: Add basic BCM6328 supportJonas Gorski
This includes CPU speed, memory size detection and working UART, but lacking the appropriate drivers, no support for attached flash.

2012-07-24MIPS: BCM63XX: Use the Chip ID register for identifying the SoCJonas Gorski
Newer BCM63XX SoCs use virtually the same CPU ID, differing only in the revision bits. But since they all have the Chip ID register at the same location, we can use that to identify the SoC we are running on.

2011-12-07MIPS: BCM63xx: Fix SDRAM size computation for BCM6345Florian Fainelli
Instead of hardcoding the amount of available RAM, read the number of effective multiples of 8MB from SDRAM_MBASE_REG.

2010-10-29MIPS: Decouple BMIPS CPU support from bcm47xx/bcm63xx SoC codeKevin Cernekee
BMIPS processor cores are used in 50+ different chipsets spread across 5+ product lines. In many cases the chipsets do not share the same peripheral register layouts, the same register blocks, the same interrupt controllers, the same memory maps, or much of anything else. But, across radically different SoCs that share nothing more than the same BMIPS CPU, a few things are still mostly constant: SMP operations Access to performance counters DMA cache coherency quirks Cache and memory bus configuration So, it makes sense to treat each BMIPS processor type as a generic "building block," rather than tying it to a specific SoC. This makes it easier to support a large number of BMIPS-based chipsets without unnecessary duplication of code, and provides the infrastructure needed to support BMIPS-proprietary features.

2010-04-12MIPS: BCM63xx: Add support for second uart.Maxime Bizon
The BCm63xx SOC has two uarts. Some boards use the second one for bluetooth. This patch changes platform device registration code to handle this. Changes to the UART driver were already merged in 6a2c7eabfd09ca7986bf96b8958a87ca041a19d8.

2009-11-02MIPS: bcm63xx: Set the correct BCM3302 CPU nameFlorian Fainelli
