- Slight tweaks, use $acr + addoq to propagate carry across the loop boundary.
- Better use of latency cycles.
- Remove duplicate folding of carry, it is not needed.
|

Implements cris_delay10ns.
|
|
- Clean up some formatting and whitespace.
|
|
These files are different for ETRAX FS and ARTPEC-3.
|
|
- Change include paths to machine specific headers (asm/arch/hwregs -> hwregs)
- Add cpu_possible_map as cpumask_t and export it.
- Drop struct pt_regs parameter from crisv32_ipi_interrupt.
- timer -> timer0
|
|
- do_signal now returns void, and does not have the previous signal set
as a parameter.
- Remove sys_rt_sigsuspend, we can use the common one instead.
- Change sys_sigsuspend to be more like x86, don't call do_signal here.
- handle_signal, setup_frame and setup_rt_frame now return -EFAULT
if we've delivered a segfault, which is used by callers to perform
necessary cleanup.
- Break long lines, correct whitespace and formatting errors.
|
|
- Update to work for ETRAX FS and ARTPEC-3
|
|
- CONFIG_ETRAXFS_SIM -> CONFIG_ETRAX_VCS_SIM
- ser_intr_mask.data_avail -> ser_intr_mask.dav
|
|
- Don't use SANITYCHECK(x) as a macro, test FAST_TIMER_SANITY_CHECKS with
ifdef. This makes it possible for automatic indent etc to work.
- Correct some whitespace errors.
- Don't initialize static variable.
|
|
- Include pinmux.h from machine specific directory.
- Add some more symbols: crisv32_pinmux_alloc, crisv32_pinmux_dealloc_fixed,
crisv32_io_get_name and crisv32_io_get
|
|
The init function should be defined always.
|
|
|
|
- Moved all calls to register_chrdev to a function called by module_init.
- Added mutex locking.
- Added better error handling at start up.
- Added BIN_TO_BCD of the month value before it is saved to the RTC.
- Corrected the month value returned by pcf8563_readreg.
- Cache the voltage low value at driver init so the battery status
information does not get 'accidentally' cleared when setting the RTC time.
- Removed obsolete CONFIG_ETRAX_RTC_READONLY
- Voltage low ioctl():s RTC_VLOW_RD -> RTC_VL_READ, RTC_VLOW_SET -> RTC_VL_CLR

collision.

Also, remove useless CVS id tag.
|
|
- Workaround for cachebug (Guinness TR 106).
- Add ARTPEC-3 support.
|
|
- Change AFLAGS to asflags-y, LDFLAGS to ldflags-y and EXTRA_CFLAGS
to ccflags-y. We only need the flags in this Makefile.

|
|
- Change include path to machine dependent header files.

- Change timers to use fasttimer_t instead of timevals.
- Change name of timeval_cmp to fasttime_cmp to highlight this.
- Register name for first timer is regi_timer0, not regi_timer.

- Don't return if we're blocking interrupts, goto done and restore interrupts.
- Disable interrupts while walking the fasttimer list, only restore
while doing the callback.

Also add board_mmcspi to build if ETRAX_SPI_MMC_BOARD is set.
(Generic MMC SPI implementation)

Now uses a DMA descriptor ring, which should avoid any unnecessary
pauses in the streams.
|
|
|
|
The two chips are somewhat different, and needs different handling.
Adds handing of the dma, dram initialization, hardware settings, io,
memory arbiter and pinmux
Also moves the dma, dram initialization and io from CRIS v32 common files.
|

Adds gpio and nandflash handling for Etrax-FS
|
|
Adds gpio and nandflash handling for Artpec-3.

- Rename CRISv32 config items which had different types from CRISv10.
(ETRAX_LED2G, ETRAX_LED2R, ETRAX_LED3G, ETRAX_LED3R, ETRAX_I2C_DATA_PORT,
ETRAX_I2C_CLK_PORT)

An extra error handling label is needed for the case where the ioremap has
succeeded.
The problem was detected using the following semantic match

Improve including of architecture dependent Kconfig files.
- Always include the architecture dependent Kconfig files.
- Wrap architecture dependent Kconfig files inside an appropriate
"if ETRAX_ARCH_Vxx" block.
This makes it possible to run the configuration even without the arch links,
which are created later in the build process.
