New in v2:
Addressed all Jonas comments but the SPI register set. Since Florian
and you have upcoming SPI drivers to submit, I'll let you decide which
block deserves its own register set.
External IRQ support has been changed slightly to handle more than 4
irq, it now uses a fixed number range above 100. It has been tested on
6348/58/68.
To make it easier to test, a complete patchset with USB/ethernet/board
support is here http://88.191.35.171/pub/bcm_6368_patches/
I will post remaining patches once this serie has been merged.
v1:
These patches add support for 6368 CPU to the existing bcm63xx code.
Basic CPU support for now, ethernet and board support will come soon.
Maxime Bizon (11):
MIPS: BCM63XX: set default pci cache line size.
MIPS: BCM63XX: hook up plat_ioremap to intercept soc registers
remapping.
MIPS: BCM63XX: call board_register_device from device_initcall()
MIPS: BCM63XX: introduce bcm_readll & bcm_writell.
MIPS: BCM63XX: cleanup cpu registers.
MIPS: BCM63XX: add more register sets & missing register definitions.
MIPS: BCM63XX: change irq code to prepare for per-cpu peculiarity.
MIPS: BCM63XX: prepare irq code to handle different external irq
hardware implementation.
MIPS: BCM63XX: handle 64 bits irq stat register in irq code.
MIPS: BCM63XX: add external irq support for non 6348 CPUs.
MIPS: BCM63XX: add support for bcm6368 CPU.

To: ralf; +Cc: Maxime Bizon, linux-mips
External irq only works for 6348, change code to prepare support of
other CPUs.

According to my sources BCM6345 has an EXTIRQ_CFG_REG, too (same place
as the others; 0x14).

of the if() above.

perf_regs[1] is (currently) always 0, so you are actually reading ...

... and writing to the REV_ID register. While it's probably harmless
as this is a read-only register, it doesn't look right.
Since BCM6368 and BCM6816 seem to be the only two actually having more
than one EXTIRQ register, I think it would make more sense to just
modify the first and check for the CPUID for the second instead of a
two element loop.
so I would do something like
if (BCMCPU_IS_6348()) {
/* do the 6348 modify of the first extirq reg */
} else {
/* do the normal modify of the first extirq reg */
}
And then add in your 6368 patch (maybe to the else branch)
if (BCMCPU_IS_6368()) {
/* modify the second ext_irq reg */
}

Apart from patch 10/11 (and the nitpick regarding the {read,write}ll
-> q) these look all fine to me. Thanks for your work!

Presumably because the CPU cache line size is 16 bytes? On MIPS we don't
set pci_dfl_cache_line_size; a patch (only compile tested) to pick a sane
default is below.
Does this work for you?
