* [ARM] Remove arch-imx from build systemSascha Hauer2009-05-072-22/+7
| | | | | | | arch-imx is superseeded by the MXC architecture support. This patch removes arch-imx from the build system. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mxc irq: make architecture runtime dependentSascha Hauer2009-05-071-35/+39
| | | | | | | | | Currently we depend on hardcoded base addresses for the interrupt controller. This prevents us from compiling in more than one i.MX architecture at a time. This patch changes the base address to a runtime calculated one. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mxc timer: make compile time independentSascha Hauer2009-05-072-178/+135

* MXC: rename mxc_map_io to architecture specific versionsSascha Hauer2009-05-0716-18/+39
| | | | | | | | This allows us to have more mapping functions for more than one i.MX architecture in the kernel. As this is the earliest board specific hook we have, also use it to set the cpu type. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* i.MX35 clock support: remove automotive pathSascha Hauer2009-05-071-28/+5
| | | | | | | | | It is no longer present in newer cores. Unfortunately Freescale decided to put the bit which decides between automotive clock path and consumer clock path in the automotive clock path direction. With current code we cannot detect the core revision, so just remove automotive path completely. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* Move dtc and libfdt sources from arch/powerpc/boot to scripts/dtcDavid Gibson2009-05-0331-11152/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | The powerpc kernel always requires an Open Firmware like device tree to supply device information. On systems without OF, this comes from a flattened device tree blob. This blob is usually generated by dtc, a tool which compiles a text description of the device tree into the flattened format used by the kernel. Sometimes, the bootwrapper makes small changes to the pre-compiled device tree blob (e.g. filling in the size of RAM). To do this it uses the libfdt library. Because these are only used on powerpc, the code for both these tools is included under arch/powerpc/boot (these were imported and are periodically updated from the upstream dtc tree). However, the microblaze architecture, currently being prepared for merging to mainline also uses dtc to produce device tree blobs. A few other archs have also mentioned some interest in using dtc. Therefore, this patch moves dtc and libfdt from arch/powerpc into scripts, where it can be used by any architecture. The vast bulk of this patch is a literal move, the rest is adjusting the various Makefiles to use dtc and libfdt correctly from their new locations.

The compatibilities are a bit different based on which kernel was used previously + Users of TI/MV kernels no longer see mtd2 "params" (mainline u-boot env is in a different place) * Filesystem is now mtd2 ... vs mtd3 + Users of GIT kernels now see mtd0 and mtd1 partitions * Filesystem partition starts 640 KBytes earlier * Filesystem is now mtd2 ... vs mtd0 * Linux now *uses* the flash-resident BBT * Removes annoying slowdown/hiccup during boot * Potentially ~64KB less space available with TI/MV kernels If you *used* NAND partitions from Linux, there is no solution that's fully compatible with all previous kernels in those respects ... ergo this "best compromise". It'd be good to back back up the filesystem data; or, carry your own backwards-compatibility patch for awhile.

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.
