In order to avoid keeping an ever growing list of chips which need to select a specific MIPS_L1_CACHE_SHIFT value introduce multiple internal and non-exposed Kconfig symbols for the various MIPS_L1_CACHE_SHIFT values out there and update the relevant Kconfig symbols to select them.

In the worst case this adds less then 128 bytes of code but on the other hand this makes code organization more clear. Signed-off-by:

With this patch we prevent the irq from being fired when it is registered. The Hardware fires an IRQ when input signal XOR polarity AND gpio mask is 1. Now we are setting polarity to a vlaue so that is is 0 when we register it. In addition we also set the irq mask register to 0 when the irq handler is initialized, so all gpio irqs are masked and there will be no unexpected irq. Signed-off-by:

BUG() can be a noop if CONFIG_BUG is not selected, leading to the following build problem on a randconfig: arch/mips/bcm63xx/cpu.c: In function 'detect_cpu_clock': arch/mips/bcm63xx/cpu.c:254:1: error: control reaches end of non-void function [-Werror=return-type] We fix this problem by replacing BUG() with panic() since it's best to handle the case of an unknown board instead of silently returning a random clock frequency.

This old wgt634u.c was trying to implement a bit ugly support for Netgear WGT634U. It provided info about LED, flash mapping & layout and was trying to handle reset button. This is not needed anymore as we have replacement for all this stuff. Signed-off-by:

This includes all devices from OpenWrt's "diag" that we support in arch code (we have entries for in enum bcm47xx_board). Signed-off-by:

Rafał Miłecki authored
So far this adds support for one Netgear model only, but it's designed and ready to add many more device. We could hopefully import database from OpenWrt. Support for SSB is currently disabled, because SSB doesn't implement IRQ domain yet. Signed-off-by:
-
Rafał Miłecki authored
So far this is mostly just a proof of concept, database consists of a single device. Creating a nice iterateable array wasn't an option because devices have different amount of LEDs. And we don't want to waste memory just because of support for a device with dozens on LEDs. Signed-off-by:

The BCM4706 has a problem with the CPU wait instruction. When r4k_wait or r4k_wait_irqoff is used will just hang and not return from a msleep(). Removing the cpu_wait functionality is a workaround for this problem. The BCM4716 does not have this problem. The BCM4706 SoC uses a MIPS 74K V4.9 CPU. Signed-off-by:

The early serial code is not needed because we already have early printk support provided by common/earlycons.c This change also fixes the following build error that occurs when CONFIG_SERIAL_8250 is not configured for Netlogic XLR boards: arch/mips/built-in.o: In function `nlm_early_serial_setup': setup.c:(.init.text+0x274): undefined reference to `early_serial_setup' make: *** [vmlinux] Error 1 Reported-by:

XLP9XX has a USB 3.0 controller on-chip with 2 xHCI ports. The USB block is similar to the one on XLP2XX, so update usb-init-xlp2.c to handle XLP9XX as well. Signed-off-by:

Most IO block offsets have changed in XLP9XX. Update iomap.h to add the new addresses of different SoC blocks like PIC, SYS, UART etc. that are needed by the base code. On XLP9xx, the SoC blocks of other nodes are seen on a PCI bus corresponding to the node. Update iomap code to reflect this. Signed-off-by:
