Until there is a generic MIPS way of handing the DTB over from bootloader to kernel we rely on a built in devicetrees. The OF code also remaps those register ranges that we use global in our drivers. Signed-off-by:

The current code uses multiple if statements for demultiplexing the different interrupt sources. Additionally, the MISC interrupt controller has 32 interrupt sources and the current code does not handles all of them. Get rid of the if statements and process all interrupt sources in a loop to fix these issues. Signed-off-by:

Make ath79_gpio_function_{en,dis}able to be wrappers around ath79_gpio_function_setup. Signed-off-by: -
Gabor Juhos authored
GPIO function selection is not working on the AR934x SoCs because the offset of the function selection register is different on those. Add a helper routine which returns the correct register address based on the SoC type, and use that in the 'ath79_gpio_function_*' routines. Signed-off-by:

Add macros to support the DSP ASE with microMIPS kernels when the toolchain does not have support. Signed-off-by:

Newer toolchains support the DSP and DSP Rev2 instructions. This patch performs a check for that support and adds compiler and assembler flags for only the files that need use those instructions. Signed-off-by:

On multi-chip boards, the first core on slave SoCs may take much more time to wakeup. Add code to wait for the core to come up before proceeding with the rest of the boot up. Update xlp_wakeup_core to also skip the boot node and the boot CPU initialization which is already complete. Signed-off-by:

Doing calibrate delay on a hardware thread will be inaccurate since it depends on the load on other threads in the core. It will also slow down the boot process when done for 128 hardware threads. Switch to a pre-computed loops per jiffy based on the core frequency. The value is computed based on the core frequency and roughly matches the value calculated by calibrate_delay(). Signed-off-by:

The XLR/XLS/XLP PIC has a 8 countdown timers which run at the PIC frequencey. One of these can be used as a clocksource to provide timestamps that is common across cores. This can be used in place of the count/compare clocksource which is per-CPU. On XLR/XLS PIC registers are 32-bit, so we just use the lower 32-bits of the PIC counter. On XLP, the whole 64-bit can be used. Provide common macros and functions for PIC timer registers on XLR/XLS and XLP, and use them to register a PIC clocksource. Signed-off-by:

Since we now use r4k cache code for Netlogic XLP, it is better to split L1 icache among the active threads, so that threads won't step on each other while flushing icache. The L1 dcache is already split among the threads in the core. Signed-off-by:

Rename function xlp_enable_pci_bswap() to xlp_config_pci_bswap(), which is a better description for its functionality. When compiled in big-endian mode, xlp_config_pci_bswap() will configure the PCIe links to byteswap. In little-endian mode, no swap configuration is needed for the PCIe controller, and the function is empty. Signed-off-by:

Provide functions ack_c0_eirr(), set_c0_eimr(), clear_c0_eimr() and read_c0_eirr_and_eimr() that do the EIMR and EIRR operations and update the interrupt handling code to use these functions. Also, use the EIMR register functions to mask interrupts in the irq code. The 64-bit interrupt request and mask registers (EIRR and EIMR) are accessed when the interrupts are off, and the common operations are to set or clear a bit in these registers. Using the 64-bit c0 access functions for these operations is not optimal in 32-bit, because it will disable/restore interrupts and split/join the 64-bit value during each register access.

An SoC normally do not define path variables for board_rev and board_type and the Broadcom SDK also uses the nvram values without a prefix in such cases. Do the same to fill these sprom attributes from nvram and do not leave them empty, because brcmsmac do not like this. Signed-off-by:

All the boot loaders I have seen are booting the kernel in raw mode by default. CFE seems to support elf kernel images too, but the default case is raw for the devices I know of. Select this option to make the kernel boot on most of the devices with the default options. Signed-off-by:

The old code just worked for nvram with a size of 0x8000 bytes. This patch adds support for reading nvram from partitions of 0xF000 and 0x10000 bytes. There is just 32KB space for the nvram, but most devices do not use the full size and this code reads the first 32KB in that case and prints a warning. Signed-off-by:
