* davinci: support different UART bases for zImage uncompressMark A. Greer2009-05-26
| | | | | | | | | | The davinci pre-kernel boot code assumes that all platforms use the same UART base address for the console. That assumption is not longer valid with some newer SoCs so determine the console UART base address from the machine number passed in from bootloader. Signed-off-by: Mark A.

* davinci: use 32-bit accesses for low-level debug macrosChaithrika U S2009-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch defines debug macros for low-level debugging for Davinci based platforms Tested on : - DM644x DaVinci EVM - DM646X DaVinciHD EVM - DM355 EVM This patch attempts to solve the low-level debug issue in DM646x. The UART on DM646x SoC allows only 32-bit access. The existing debug-macro.S uses the macros from debug-8250.S file. This led to garbage serial out in the case of DM646x. The inclusion of debug-8250.S does not allow for run time fix for this issue. There are compile time errors due to multiple definitions of the macros. Also when building a single image for multiple DaVinci Platforms, the ifdefs cannot be relied upon. The solution below does not include the debug-8250.S file and defines the necessary macros. This solution was arrived at after observing that word access does not affect the low-level debug messages on DM644x/DM355. The other approach to this issue is to use the UART module information available in the peripheral registers to decide the access mechanism. But this will have to be done for every access of UART specifically for DM646x. Also this calls for a modification of the debug-8250.S file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the DaVinci GPIO code to work better on non-dm6446 parts, notably the dm355: - Only handle the number of GPIOs the chip actually has. So for example on dm6467, GPIO-42 is the last GPIO, and trying to use GPIO-43 now fails cleanly; or GPIO-72 on dm6446. - Enable GPIO interrupts on each 16-bit GPIO-irq bank ... previously, only the first five were enabled, so GPIO-80 and above (on dm355) wouldn't trigger IRQs. - Use the right IRQ for each GPIO bank. The wrong values were used for dm355 chips, so GPIO IRQs got routed incorrectly. - Handle up to four pairs of 16-bit GPIO banks ... previously only three were handled, so accessing GPIO-96 and up (e.g. on dm355) would oops. - Update several comments that were dm6446-specific. Verified by receiving GPIO-1 (dm9000) and GPIO-5 (msp430) IRQs on the DM355 EVM. One thing this doesn't do is handle the way some of the GPIO numbers on dm6467 are reserved but aren't valid as GPIOs. Some bitmap logic could fix that if needed. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

* | davinci: major rework of clock, PLL, PSC infrastructureKevin Hilman2009-04-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a significant rework of the low-level clock, PLL and Power Sleep Controller (PSC) implementation for the DaVinci family. The primary goal is to have better modeling if the hardware clocks and features with the aim of DVFS functionality. Highlights: - model PLLs and all PLL-derived clocks - model parent/child relationships of PLLs and clocks - convert to new clkdev layer - view clock frequency and refcount via /proc/davinci_clocks Special thanks to significant contributions and testing by David Brownell.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a device driver for the NAND flash controller found on the various DaVinci family chips. It handles up to four SoC chipselects, and some flavors of secondary chipselect (e.g. based on upper bits of the address bus) as used with some multichip packages. (Including the 2 GiB chips used on some TI devel boards.) The 1-bit ECC hardware is supported (3 bytes ECC per 512 bytes data); but not yet the newer 4-bit ECC (10 bytes ECC per 512 bytes data), as available on chips like the DM355 or OMAP-L137 and needed with the more error-prone MLC NAND chips. This is a cleaned-up version of code that's been in use for several years now; sanity checked with the new drivers/mtd/tests.

* | [ARM] pass reboot command line to arch_reset()Russell King2009-03-19
|/ | | | | | | | | | | | | | | OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.

* [ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King2008-11-29
| | | | | | | | | | | | | When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.

What most platforms are using is bus_addr == phys_addr so such is the default. One exception is ebsa110 which has no DMA what so ever, so the actual definition is not important except only for proper compilation. Also added a comment about the special footbridge bus translation. Let's also remove comments alluding to set_dma_addr which is not (and should not) be commonly used.
