[PATCH 2/5] MIPS: bcm63xx: fix SDRAM size computation for BCM6345

From: Florian Fainelli <ffainelli@freebox.fr>

Instead of hardcoding the amount of available RAM, read the number of
effective multiples of 8MB from SDRAM_MBASE_REG.

For consistency with other parts of the code, I would rather keep it.

[PATCH 4/5] MIPS: bcm63xx: remove BCM6345 hacks to read base boot address

[Florian Fainelli]

From: Florian Fainelli <ffainelli@freebox.fr>

Though BCM6345 does not technically have the same MPI register layout
than the other SoCs, reading the chip-select registers is done the same
way, and particularly for chip-select 0, which is the boot flash.
Now that BCM6345 has a MPI_BASE register defined, use it.

[PATCH 5/5] MIPS: bcm63xx: fix GPIO set/get for BCM6345

[Florian Fainelli]

From: Florian Fainelli <ffainelli@freebox.fr>

On BCM6345, the register offsets for the set/get GPIO registers is wrong
in order not add more complexity, use the HI_* variants for BCM6345
which results in reading/writing from/to the right register offsets.
