xtensa: rework {CONFIG,PLATFORM}_DEFAULT_MEM_START

2018-08-20T19:28:03+00:00

Drop PLATFORM_DEFAULT_MEM_START from the platform/hardware.h headers. Provide definition of CONFIG_DEFAULT_MEM_START always, allow changing it only in noMMU configurations when PLATFORM_WANT_DEFAULT_MEM is selected. Change prompt and description so that it's clear that it controls PAGE_OFFSET and PHYS_OFFSET. Signed-off-by: Max Filippov

xtensa: drop unused {CONFIG,PLATFORM}_DEFAULT_MEM_SIZE

2018-08-20T19:27:52+00:00

Now that noMMU cache attributes are set up separately drop no longer used macro PLATFORM_DEFAULT_MEM_SIZE and config symbol CONFIG_DEFAULT_MEM_SIZE used for setting it. Signed-off-by: Max Filippov

xtensa: don't use linux IRQ #0

2017-06-05T23:53:10+00:00

Linux IRQ #0 is reserved for error reporting and may not be used. Increase NR_IRQS for one additional slot and increase irq_domain_add_legacy parameter first_irq value to 1, so that linux IRQ #0 is not associated with hardware IRQ #0 in legacy IRQ domains. Introduce macro XTENSA_PIC_LINUX_IRQ for static translation of xtensa PIC hardware IRQ # to linux IRQ #. Use this macro in XTFPGA platform data definitions. This fixes inability to use hardware IRQ #0 in configurations that don't use device tree and allows for non-identity mapping between linux IRQ # and hardware IRQ #.

xtensa: xtfpga: fix integer overflow in TASK_SIZE

2015-11-02T15:02:55+00:00

This fixes the following warning when default memory region crosses 0x80000000: arch/xtensa/include/asm/processor.h:40:47: warning: integer overflow in expression [-Woverflow] #define TASK_SIZE (PLATFORM_DEFAULT_MEM_START + PLATFORM_DEFAULT_MEM_SIZE) ^ Signed-off-by: Max Filippov

xtensa: xtfpga: fix hardware lockup caused by LCD driver

2015-02-27T04:55:29+00:00

LCD driver is always built for the XTFPGA platform, but its base address is not configurable, and is wrong for ML605/KC705. Its initialization locks up KC705 board hardware. Make the whole driver optional, and its base address and bus width configurable. Implement 4-bit bus access method. Cc: stable@vger.kernel.org Signed-off-by: Max Filippov

xtensa: make PLATFORM_DEFAULT_MEM parameters configurable

2014-10-21T09:28:59+00:00

This allows using xtfpga platform with both MMU and noMMU cores. Signed-off-by: Max Filippov

xtensa: add SMP support

2014-01-14T18:19:58+00:00

This is largely based on SMP code from the xtensa-2.6.29-smp tree by Piet Delaney, Marc Gauthier, Joe Taylor, Christian Zankel (and possibly other Tensilica folks). Signed-off-by: Max Filippov Signed-off-by: Chris Zankel
