MIPS: Netlogic: replace early_init_devtree() call

2013-11-06T22:14:04+00:00

The early_init_devtree() API was removed in linux-next for 3.13 with
commit "mips: use early_init_dt_scan". This causes Netlogic XLP compile
to fail:

arch/mips/netlogic/xlp/setup.c:101: undefined reference to `early_init_devtree'

Add xlp_early_init_devtree() which uses the __dt_setup_arch() to
handle early device tree related initialization to fix this.

MIPS: Netlogic: Add support for USB on XLP2xx

2013-09-03T21:22:20+00:00

Add USB intialization code to handle the new XLP2XX USB 3.0 block.
This adds xlp/usb-init-xlp2.c to initialize the XLP2XX USB glue-logic
for XHCI and EHCI. Interrupt and IO offset code in xlp-hal/iomap.h
and xlp/nlm_hal.c is also updated for the new USB block.

MIPS: Netlogic: XLP2xx update for I2C controller

2013-09-03T21:22:20+00:00

XLP2xx has a new I2C controller which has 4 buses connected to
it. Update the IO offset and IRQ mapping code to reflect this.

MIPS: Netlogic: XLP2XX CPU and PIC frequency

2013-09-03T21:22:19+00:00

Add code to calculate the CPU and PIC frequency for XLP2XX SoCs.

Since the PIC frequency on XLP2XX can be configured, add a new macro
pic_timer_freq() to be used in netlogic/common/time.c.

MIPS: Netlogic: Add support for XLP2XX

2013-09-03T21:22:19+00:00

XLP2XX is first in the series of 28nm XLPII processors.

The changes are to:
* Add processor ID for XLP2XX to asm/cpu.h and kernel/cpu-probe.c.
* Add a cpu_is_xlpii() function to check for XLPII processors.
* Update xlp_mmu_init() to use config4 to enable extended TLB.

MIPS: Netlogic: Read memory from DRAM BARs

2013-09-03T21:22:18+00:00

Read the memory from the Bridge DRAM BARs, if it is not passed in
from the device tree. This will allow us to remove memory configuration
from built in device trees.

MIPS: Netlogic: Fix sign extension in PIC write

2013-06-13T15:46:42+00:00

This does not cause a problem yet, but we do not want to write 1
to reserved bits.

MIPS: Netlogic: move cpu_ready array to boot area

2013-06-13T15:46:42+00:00

Move the nlm_cpu_ready[] array used by the cpu wakeup code to the
boot area, along with rest of the boot parameter code.

MIPS: Netlogic: Split reset code out of smpboot.S

2013-06-13T15:46:42+00:00

The reset and core initialization code should be available for
uniprocessor as well. This changes is just to take out the code
into a different file, without any change to the logic.

The change for  uniprocessor initialization code is in a later patch.
