MIPS: BCM63xx: Move bcm63xx_gpio_init() to bcm63xx_register_devices().

2015-03-25T12:47:55+00:00

When called from prom init code, bcm63xx_gpio_init() will fail as it will call gpiochip_add() which relies on a working kmalloc() to alloc the gpio_desc array and kmalloc is not useable yet at prom init time. Move bcm63xx_gpio_init() to bcm63xx_register_devices() (an arch_initcall) where kmalloc works.

MIPS: BCM63XX: always register bmips smp ops

Use the return value for guarding further SMP setup. Signed-off-by: Jonas Gorski Signed-off-by: John Crispin Patchwork: http://patchwork.linux-mips.org/patch/6249/

MIPS: BMIPS: add a smp ops registration helper

2014-01-22T19:18:52+00:00

Add a helper similar to the generic register_XXX_smp_ops() for bmips. Register SMP UP ops in case of BMIPS32/3300. Signed-off-by: Jonas Gorski Signed-off-by: John Crispin Patchwork: http://patchwork.linux-mips.org/patch/6248/

MIPS: BMIPS: change compile time checks to runtime checks

2014-01-22T19:18:51+00:00

Allow building for all bmips cpus at the same time by changing ifdefs to checks for the cpu type, or adding appropriate checks to the assembly. Since BMIPS43XX and BMIPS5000 require different IPI implementations, split the SMP ops into one for each, so the runtime overhead is only at registration time for them.

MIPS: BCM63XX: disable SMP also on BCM3368

BCM3368 has the same shared TLB as BCM6358. Signed-off-by: Jonas Gorski Signed-off-by: John Crispin Patchwork: http://patchwork.linux-mips.org/patch/6239/

MIPS: BCM63xx: Enable second core SMP on BCM6328 if available

BCM6328 has a OTP which tells us if the second core is available. Signed-off-by: Jonas Gorski Cc: linux-mips@linux-mips.org Cc: John Crispin Cc: Maxime Bizon Cc: Florian Fainelli Cc: Kevin Cernekee Patchwork: https://patchwork.linux-mips.org/patch/5490/ Signed-off-by: Ralf Baechle

MIPS: BCM63xx: Add SMP support to prom.c

2013-07-01T13:10:59+00:00

This involves two changes to the BSP code: 1) register_smp_ops() for BMIPS SMP 2) The CPU1 boot vector on some of the BCM63xx platforms conflicts with the special interrupt vector (IV). Move it to 0x8000_0380 at boot time, to resolve the conflict.

MIPS: BCM63XX: add support for BCM3368 Cable Modem

2013-07-01T13:10:53+00:00

The Broadcom BCM3368 Cable Modem SoC is extremely similar to the existing BCM63xx DSL SoCs, in particular BCM6358, therefore little effort in the existing code base is required to get it supported. This patch adds support for the following on-chip peripherals: - two UARTS - GPIO - Ethernet - SPI - PCI - NOR Flash The most noticeable difference with 3368 is that it has its peripheral register at 0xfff8_0000 we check that separately in ioremap.h. Since 3368 is identical to 6358 for its clock and reset bits, we use them verbatim.
