2008-07-14Blackfin arch: Fix bug - Kernel does not boot if re-program clocksMichael Hennerich1-27/+0
Don't write conflicting data to EBIU_SDBCTL after the SDRAM is configured. This can cause data corruption, since we might change SDRAM row and column addressing modes. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>

2008-04-24[Blackfin] arch: Prevent potential Core Hang situationMichael Hennerich1-4/+30
If the new value written to the PLL_CTL or VR_CTL register is the same as the previous value, the PLL wake-up will occur immediately (PLL is already locked), but the core and system clock will be bypassed for the PLL_LOCKCNT duration. For this interval, code will execute at the CLKIN rate instead of at the expected CCLK rate. Software should guard against this condition by comparing the current value to the new value before writing the new value.

2007-12-24[Blackfin] serial driver: fix bug - cache the bits of the LSR on systems where the LSR is read-to-clearMike Frysinger1-1/+18
Cache the bits of the LSR on systems where the LSR is read-to-clear so that we can safely read the LSR in random places. this fixes older parts where break/framing/parity/overflow was not being detected at all in PIO mode, and this fixes newer parts where break/framing/parity/overflow was being reported all the time without being cleared.

2007-12-24[Blackfin] arch: Fix gpio label handlingMichael Hennerich1-0/+2
early serial init also utilizes the peripheral request api - however at this point bfin_gpio_init didn't allocate memory for the labels. So we always have two zombies (allocated pin functions without labels) This happens before the initcalls - We now allocate memory statically. Define MAX_RESOURCES individually for each cpu.

2007-11-21Blackfin arch: cplb and map header file cleanupMike Frysinger2-19/+5
- remove duplicated defines for the BF561 - generalize L2 support (so that it works for BF54x) and mark it executable - add support for reading/executing the Boot ROM sections (since it has data/functions we may need at runtime) - and fixup names for each map Signed-off-by: Mike Frysinger <michael.frysinger@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>

2007-07-25Blackfin arch: revise anomaly handling by basing things on the compiler not the kconfig definesMike Frysinger2-143/+237
revise anomaly handling by basing things on the compiler not the kconfig defines, so the header is stable and usable outside of the kernel. This also allows us to move some code from preprocessing to compiling (gcc culls dead code) which should help with code quality (readability, catch minor bugs, etc...).

2007-07-12Blackfin arch: initial supporting for BF548-EZKITRoy Huang1-0/+3
The ADSP-BF54x was specifically designed to meet the needs of convergent multimedia applications where system performance and cost are essential ingredients. The integration of multimedia, human interface, and connectivity peripherals combined with increased system bandwidth and on-chip memory provides customers a platform to design the most demanding applications. Since now, ADSP-BF54x will be supported in the Linux kernel and bunch of related drivers such as USB OTG, ATAPI, NAND flash controller, LCD framebuffer, sound, touch screen will be submitted later.
