MIPS: BMIPS: Add support for BCM63268

2016-05-13T12:02:09+00:00

This SoC is very similar to BCM63168 and Broadcom usually refers to them as
BCM63268.
Add BCM63268 and missing BCM63168 to device tree documentation.

MIPS: BMIPS: Add device tree example for BCM6358

2016-05-13T12:02:09+00:00

This adds a device tree example for SFR Neufbox4 (Sercomm version), which
also serves as a real example for brcm,bcm6358-leds.

MIPS: BMIPS: Add BCM6358 support

2016-05-13T12:02:09+00:00

BCM6358 has a shared TLB which conflicts with current SMP support, so it must
be disabled for now.
BCM6358 uses >= 0xfffe0000 addresses for internal registers, which need to be
remapped (by using a simplified version of BRCM63xx ioremap.h).
However, 0xfff80000 is a better address, since it also covers BCM3368, leaving
the possibility to add it in the future.

MIPS: BMIPS: Add early CPU initialization code

2016-05-13T12:01:55+00:00

Port the stblinux-3.3 code to perform a bunch of CPU-specific initialization,
make it compatible with run-time detection of the CPU, and unroll the
brcmstb-specific macros: BDEV_RB(), BDEV_UNSET.

The "pref 30" disabling is done as a quirk. This is a preliminary change to
allow the use of the "rotr" instruction gated by cpu_has_rixi.

irqchips/bmips: Add bcm6345-l1 interrupt controller

2016-02-08T14:03:42+00:00

Add the BCM6345 interrupt controller based on the SMP-capable BCM7038
and the BCM3380 but with packed interrupt registers.

Add the BCM6345 interrupt controller to a list with the existing BCM7038
so that interrupts on CPU1 are not ignored.

Update the maintainers file list for BMIPS to include this driver.

MIPS: Make MIPS_CMDLINE_DTB default

2015-11-11T07:38:37+00:00

Seval of-enabled machines (bmips, lantiq, xlp, pistachio, ralink) copied
the arguments from dtb to arcs_command_line to prevent the kernel from
overwriting them.

Since there is now an option to keep the dtb arguments, default to the
new option remove the "backup" to arcs_command_line in case of USE_OF is
enabled, except for those platforms that still take the bootloader
arguments or do not use any at all.

mips/irq: prepare for drivers/irqchip/irqchip.h removal

2015-07-31T18:51:21+00:00

The IRQCHIP_DECLARE macro migrated to 'include/linux/irqchip.h'.

See commit 91e20b5040c67c51aad88cf87db4305c5bd7f79d
("irqchip: Move IRQCHIP_DECLARE macro to include/linux/irqchip.h").

This patch removes inclusions of private header 'drivers/irqchip/irqchip.h'and
replaces them with the inclusion of 'include/linux/irqchip.h'.

MIPS: BMIPS: Accept UHI interface for passing a dtb

2015-06-21T19:54:17+00:00

Detect and use passed dtb address using the UHI interface. This allows for
booting with a vmlinux.bin appended dtb instead of using a built-in one.

MIPS: BMIPS: Add support for Broadcom BCM97435SVMB

2015-06-21T19:53:34+00:00

Add a DTS file and Kconfig entry for the BCM97435SVMB evaluation board
using bcm7435.dtsi as an example.

The current code needs some tweaking to allow us to use the
dual-threaded dual BMIPS5200 CPUs, so for now we limit ourselves to
allowing just a single CPU to be booted.
