Try to keep the naming conventions consistent, so: SPI_ADC_BF533 -> BFIN_SPI_ADC TWI_LCD -> BFIN_TWI_LCD Signed-off-by:Mike Frysinger <vapier@gentoo.org>

For systems where the core cycles are not a usable tick source (like SMP or cycles gets updated), enable gptimer0 as an alternative. Signed-off-by:

Add some notes for anomaly 05000120 to make sure we work around it. Signed-off-by:

The two high address lines on the BF51x are not dedicated which means we need to handle them like any other peripheral pin if we want to access the upper 2MB of parallel flash. Signed-off-by:

Workaround anomaly 05000227 by only using the scratch pad for stack when absolutely necessary. The core code which reprograms clocks really only touches MMRs directly with constants. Signed-off-by: -

This init code existed only to dump a printk(), and not even a useful one. Signed-off-by: -

Our early L1 relocate code may implicitly call code which lives in L1 memory. This is due to the dma_memcpy() rewrite that made the DMA code lockless and safe to be used by multiple processes. If we start the early DMA memcpy to relocate things into L1 instruction but then our DMA memcpy code calls a function that lives in L1, things fall apart. As such, create a small dedicated DMA memcpy routine that we can assume sanity at boot time. Reported-by:

Add some defines to make the BF538/BF561 look like most other Blackfin parts in that it has a MDMA0 channel available for low level init. Signed-off-by:

Make sure our bfin_addr_dcachable() function flags cached L2 SRAM properly else memory easily goes unflushed when working with DMA. Signed-off-by: -

The I/O port functions take ints, so we need to cast them up before passing to our read/write funcs to avoid ugly messes of warnings. Signed-off-by:

The traps test case 21 "exception 0x3f: l1_instruction_access" would make the kernel panic on BF533's because we end up calling show_stack() infinitely. Signed-off-by:

Mike Frysinger authored
Make sure we flush all data caches and their write buffers before flushing icache, otherwise random edge cases could crop up where stale data is read into icache from external memory. As fallout, punt the combined icache + dcache flush function since we cannot safely do them back to back -- the SSYNC is needed between the dcache flush and the icache flush. Signed-off-by:
