* fix software breakpoints on xscaleMike Dunn2010-03-221-2/+12
| | | | | | | | | | | | | | | | | | | | | | This patch fixes xscale software breakpoints by cleaning the dcache and invalidating the icache after the bkpt instruction is inserted or removed. The icache operation is necessary in order to flush the fetch buffers, even if the icache is disabled (see section 4.2.7 of the xscale core developer's manual). The dcache is presumed to be enabled; no harm done if not. The dcache is also invalidated after cleaning in order to safeguard against a future load of invalid data, in the event that cache_clean_address points to memory that is valid and in use. Also corrected a confusing typo I noticed in a comment. TODO (or not TODO...?): the xscale's 2K "mini dcache" is not cleaned. This cache is not used unless the 'X' bit in the page table entry is set. This is a proprietary xscale extension to the ARM architecture. If a target's OS or executive makes use of this for memory regions holding code, the breakpoint problem will persist. Flushing the mini dcache requires that 2K of valid cacheable memory (mapped with 'X' bit set) be designated by the user for this purpose. The debug handler that gets downloaded to the target will also need to be extended.

* ft2232 init mess cleanupDavid Brownell2010-03-211-60/+99
| | | | | | | | | | | | | | | | | | | | | | In the ft2232 driver, initialization for many layouts punts to a routine called usbjtag_init(), instead of a routine specific to each layout. That routine is a mess built around a "what type layout am I" core. That's a bad design ... in this case, especially so, since it bypasses the layout-specific dispatch which was just done, and obfuscates the initialization which is at least somewhat generic, instead of being specific to the "usbjtag" layout. Split and document out the generic parts of usbjtag_init(), and make the rest of those layouts have layout-specific init methods. Also, rename usbjtag_reset() ... that also was not specific to the "usbjtag" layout, and thus contributed to the previous code structure confusion. (Eventually, all layout-specific code (and method tables) should probably live in files specific to each layout. These changes will facilitate those and other cleanups to this driver.)

* Fix underlying problem with xscale icache and dcache commandsMike Dunn2010-03-181-6/+11
| | | | | | | | | | | | | | | | | | | | Fix problem with the xscale icache and dcache commands. Both commands were enabling or disabling the mmu, not the caches I didn't look any further after my earlier patch fixed the trivial problem with command argument parsing. Turns out the underlying code was broken. The resolution is straightforward when you look at the arguments to xscale_enable_mmu_caches() and xscale_disable_mmu_caches(). I finally took a deeper look after dumping the cp15 control register (XSCALE_CTRL) and seeing that the cache bits weren't changing, but the mmu bit was (which caused all manner of grief, as you can imagine). This has been tested and works OK now. src/target/xscale.c | 17 +++++++++++------ 1 files changed, 11 insertions(+), 6 deletions(-) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

| | | | | | | | | | | | | | | | Until this time only basic SLC functionality exists when you want to use SLC to access external nand flash. Basic functionality can be selected with command: lpc3180 select 0 slc It is anyway very slow to write/read to/from nand flash. With the new command, SLC speed improved about 20 times, and hardware ECC info also read/written from/to nand flash OOB area: lpc3180 select 0 slc bulk Speed improvement achieved by using working are in SRAM of the LPC3250 chip and controlling DMA controller to interact between SRAM and SLC peripheral.

* image loading: fix problem with offsets > 0x80000000Bradey Honsinger2010-03-164-4/+4
| | | | | | | | | | | | | | | Fixes bug that prevented users from specifying a base address of 0x80000000 or higher in image commands (flash write_image, etm image, xscale trace_image). image.base_address is an offset from the start address contained in the image file (if there is one), or from 0 (for binary files). As a signed 32-bit int, it couldn't be greater than 0x7fffffff, which is a problem when trying to write a binary file to flash above that address. Changing it to a 64-bit long long keeps it as a signed offset, but allows it to cover the entire 32-bit address space. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
