2024-06-27mips: bmips: setup: make CBR address configurableChristian Marangi1-1/+5
Add support to provide CBR address from DT to handle broken SoC/Bootloader that doesn't correctly init it. This permits to use the RAC flush even in these condition. To provide a CBR address from DT, the property "brcm,bmips-cbr-reg" needs to be set in the "cpus" node. On DT init, this property presence will be checked and will set the bmips_cbr_addr value accordingly. Also bmips_rac_flush_disable will be set to false as RAC flush can be correctly supported. The CBR address from DT will overwrite the cached one and the one set in the CBR register will be ignored. Also the DT CBR address is validated on being outside DRAM window.

2024-06-27mips: bmips: rework and cache CBR addr handlingChristian Marangi1-0/+4
Rework the handling of the CBR address and cache it. This address doesn't change and can be cached instead of reading the register every time. This is in preparation of permitting to tweak the CBR address in DT with broken SoC or bootloader. bmips_cbr_addr is defined in setup.c for each arch to keep compatibility with legacy brcm47xx/brcm63xx and generic BMIPS target.

2024-01-26MIPS: BCM63XX: Fix missing prototypesFlorian Fainelli1-1/+1
Most of the symbols for which we do not have a prototype can actually be made static and for the few that cannot, there is already a declaration in a header for it. Signed-off-by: Florian Fainelli <[email protected]> Signed-off-by: Thomas Bogendoerfer <[email protected]>
2020-10-12MIPS: replace add_memory_region with memblockThomas Bogendoerfer1-1/+1
add_memory_region was the old interface for registering memory and was already changed to used memblock internaly. Replace it by directly calling memblock functions. Signed-off-by: Thomas Bogendoerfer <[email protected]>

2015-03-25MIPS: BCM63xx: Move bcm63xx_gpio_init() to bcm63xx_register_devices().Nicolas Schichan1-0/+4
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.

2013-07-01MIPS: BCM63XX: add support for BCM3368 Cable ModemFlorian Fainelli1-0/+3
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.

2013-03-19Revert "MIPS: BCM63XX: Call board_register_device from device_initcall()"Jonas Gorski1-1/+1
This commit causes a race between PCI scan and SSB fallback SPROM handler registration, causing the wifi to not work on slower systems. The only subsystem touched from board_register_devices is platform device registration, which is safe as an arch init call. This reverts commit d64ed7ada2f689d2c62af1892ca55e47d3653e36 [MIPS: BCM63XX: Call board_register_device from device_initcall()].

This patch fixes a lockup on BCM6345 where setting the PLL soft reset bit will also lock the other blocks including UART.
